Question 1Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

Under FIFRA, which federal agency is responsible for registering pesticide products and approving their labels?

  1. The Food and Drug Administration
  2. The U.S. Environmental Protection Agency Correct answer.
  3. The U.S. Department of Agriculture
  4. The Occupational Safety and Health Administration

Explanation

FIFRA authorizes the U.S. EPA to register pesticides and approve labeling before a product may be sold or distributed. USDA, FDA, and OSHA have related roles but do not register pesticides or approve pesticide labels.

Question 2Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

A pesticide product's label bears an EPA Registration Number. What does this number indicate?

  1. The product may be sold without any further state review
  2. The product has been tested and proven safe for all users
  3. The product is certified organic by the federal government
  4. The product has been registered with EPA for the uses stated on the label Correct answer.

Explanation

The EPA Registration Number shows the product is registered under FIFRA for the uses described on its approved label. Registration does not mean the product is risk-free, nor does it replace state registration requirements.

Question 3Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

Which statement best describes the legal status of the pesticide label under FIFRA?

  1. The label is enforceable only when the product is used on agricultural crops
  2. The label is part of the legal registration and its directions must be followed Correct answer.
  3. The label is advisory guidance that applicators may adapt to local conditions
  4. The label applies only to the original purchaser of the product

Explanation

The label is legally binding and is considered part of the registration; use inconsistent with the label is a violation of FIFRA. Applicators may not deviate from label directions even for local conditions.

Question 4Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

Under FIFRA, using a registered pesticide in a manner inconsistent with its labeling is:

  1. Allowed when the crop is not for human consumption
  2. Permitted if the pest is not listed on the label
  3. A violation of federal law Correct answer.
  4. Permitted if the applicator is certified

Explanation

FIFRA makes it unlawful to use a pesticide in a manner inconsistent with its labeling. Certification does not authorize off-label use, and the restriction applies regardless of the pest or crop.

Question 5Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

Before a pesticide product may legally be distributed or sold in Nevada, the registrant generally must:

  1. Obtain state registration through the Nevada Department of Agriculture Correct answer.
  2. Receive approval from the nearest university extension office
  3. Post a bond with the county sheriff
  4. Obtain a local business license in each county where it is sold

Explanation

Nevada requires pesticide products to be registered with the state, administered by the Nevada Department of Agriculture, in addition to federal EPA registration. County licenses or sheriff bonds are not the mechanism for state pesticide registration.

Question 6Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

In Nevada, which agency administers the pesticide applicator certification and licensing program?

  1. The Nevada State Board of Health
  2. The Nevada Public Utilities Commission
  3. The Nevada Department of Agriculture Correct answer.
  4. The Nevada Department of Wildlife

Explanation

The Nevada Department of Agriculture administers pesticide registration, applicator certification, and related enforcement under state law. The other listed agencies regulate different areas and do not license pesticide applicators.

Question 7Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

A certified commercial applicator's certification in Nevada is generally valid for a defined period. Which practice keeps the certification in force?

  1. Renewing before expiration and meeting continuing education requirements Correct answer.
  2. Relying on the federal registration of the product used
  3. Paying a late fee each year instead of renewing
  4. Applying for renewal only after the certification has lapsed

Explanation

Certifications expire and must be renewed, typically with continuing education credits, to remain valid. Allowing a certification to lapse means the applicator is no longer certified until requirements are met again.

Question 8Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

Under FIFRA, which of the following is classified as a restricted use pesticide?

  1. A product that may cause unreasonable adverse effects without additional regulatory restrictions Correct answer.
  2. A product that requires no personal protective equipment
  3. A product registered exclusively for homeowner use
  4. A product sold only in containers larger than one gallon

Explanation

EPA classifies a pesticide as restricted use when it may cause unreasonable adverse effects on humans or the environment even when used as directed, so it is limited to certified applicators or persons under their supervision. Container size, homeowner-only marketing, and PPE requirements are not the basis for this classification.

Question 9Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

Who may legally apply a restricted use pesticide under FIFRA?

  1. Any adult who has read the label
  2. Any employee of a licensed business
  3. Any person who has completed a safety training video
  4. A certified applicator, or a person under the direct supervision of a certified applicator as allowed by label and state rules Correct answer.

Explanation

Restricted use pesticides may be applied only by certified applicators or by persons under their direct supervision where the label and state law permit. Reading a label or general training does not confer legal authority to apply restricted use products.

Question 10Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

An applicator wants to apply a product to a use site that does not appear on the label. What is the correct course of action?

  1. Do not make the application, because unlabeled use sites are not permitted Correct answer.
  2. Apply only if the target pest is listed on the label
  3. Apply at a reduced rate to limit risk
  4. Apply and document the decision in the application record

Explanation

A pesticide may be used only on sites listed on its label; using it on an unlisted site is a use inconsistent with labeling. Reduced rates, listed pests, or recordkeeping do not authorize unlabeled site use.

Question 11Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

A product label states a maximum application rate per acre per year. An applicator makes several applications in one season. How should the applicator manage the total?

  1. Split applications so each is below the maximum, ignoring the annual total
  2. Apply the maximum rate each time regardless of season total
  3. Track cumulative use and stay within the annual maximum stated on the label Correct answer.
  4. Exceed the maximum if pest pressure is unusually high

Explanation

Annual maximum rates are cumulative limits; applicators must track all applications across the year and not exceed the labeled total. Pest pressure does not justify exceeding labeled maximums.

Question 12Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

What is the purpose of the signal word on a pesticide label, such as DANGER, WARNING, or CAUTION?

  1. To indicate the relative acute toxicity hazard of the product Correct answer.
  2. To indicate the shelf life of the product
  3. To indicate the target pest category
  4. To indicate the product's EPA registration status

Explanation

Signal words communicate the relative acute toxicity of the formulated product, with DANGER reflecting the highest hazard and CAUTION the lowest. They do not convey registration status, shelf life, or pest category.

Question 13Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

The precautionary statements section of a pesticide label typically includes which information?

  1. The registration expiration date of the state license
  2. The price of the product
  3. Hazards to humans and domestic animals and required personal protective equipment Correct answer.
  4. The name of the nearest emergency room

Explanation

Precautionary statements describe hazards to humans, animals, and the environment and specify required PPE and first aid. They do not include pricing, local medical facilities, or license dates.

Question 14Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

An applicator is mixing a product whose label requires chemical-resistant gloves, long sleeves, and a respirator. The applicator plans to wear only gloves. This plan is:

  1. Not acceptable, because all PPE specified on the label must be worn Correct answer.
  2. Acceptable, because gloves are the most important item
  3. Acceptable, because the product is diluted during mixing
  4. Acceptable, because mixing takes only a few minutes

Explanation

Label-specified PPE is a legal requirement and must be worn for the tasks indicated, including mixing and loading. Partial PPE use is a label violation and increases exposure risk.

Question 15Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

Under FIFRA, a pesticide dealer or distributor may sell a general-use pesticide to:

  1. Only licensed businesses
  2. Only persons who own agricultural land
  3. Any purchaser, since general-use products do not require certification Correct answer.
  4. Only certified applicators

Explanation

General-use pesticides may be purchased and used by the general public without certification, though label directions still apply. Restricted use products, by contrast, are limited to certified applicators or supervised persons.

Question 16Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

Which of the following best describes the Worker Protection Standard's relationship to pesticide labeling?

  1. It imposes additional worker safety requirements that apply in addition to label directions Correct answer.
  2. It applies only to homeowners applying pesticides
  3. It eliminates the need for applicator certification
  4. It replaces label PPE requirements with its own standards

Explanation

The Worker Protection Standard sets requirements for agricultural workers and handlers that operate alongside, not instead of, label directions. Compliance with the label does not excuse noncompliance with WPS, and vice versa.

Question 17Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

An applicator discovers that a product's label has been updated and the new label prohibits a practice the old label allowed. Which version governs current use?

  1. The version printed in a generic pest management guide
  2. The label in effect for the product at the time of the application Correct answer.
  3. The oldest label the applicator can find
  4. Whichever version the applicator prefers

Explanation

Applicators must follow the current label for the product being used; older labels do not authorize practices now prohibited. Generic guides and personal preference cannot override the label.

Question 18Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

What information does the EPA Registration Number on a label typically NOT provide?

  1. The expiration date of the applicator's certification Correct answer.
  2. The product number assigned to the specific product
  3. Identification that the product is registered with EPA
  4. The company number assigned to the registrant

Explanation

The EPA Registration Number identifies the registrant and product and confirms federal registration, but it says nothing about an individual applicator's certification. Certification status is tracked separately by the state.

Question 19Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

Which practice is required when an applicator must store a pesticide?

  1. Remove the label to prevent fading
  2. Store it near food or animal feed for convenience
  3. Store it in its original labeled container with the label intact Correct answer.
  4. Transfer it to an unmarked container to save space

Explanation

Pesticides must be kept in their original labeled containers so that the label remains available and the contents are identifiable. Removing or covering labels and storing near food or feed create serious hazards and violate label directions.

Question 20Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

Under FIFRA, which of the following is a legal requirement for a pesticide container?

  1. It must be returnable to the manufacturer
  2. It must be made of metal
  3. It must hold at least one gallon
  4. It must bear the registered label when sold or distributed Correct answer.

Explanation

Pesticide containers must bear the registered label when distributed or sold, ensuring users have the required directions and warnings. Material, returnability, and size are not FIFRA labeling requirements.

Question 21Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

An applicator keeps required records of restricted use pesticide applications. Which statement about recordkeeping is most accurate?

  1. Records may be discarded immediately after the application
  2. Records are required only for applications on lawns
  3. Records must be kept as required by federal and state rules and made available for inspection Correct answer.
  4. Records are optional if the applicator is certified

Explanation

Certified applicators must maintain records of restricted use pesticide applications for the period required by federal and state rules and provide them to authorized officials on request. Recordkeeping is mandatory and not limited to lawn applications.

Question 22Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

A commercial applicator in Nevada applies a restricted use pesticide for a client. Who is responsible for ensuring the application complies with the label?

  1. The client who requested the service
  2. The supplier who sold the product
  3. The certified applicator making or supervising the application Correct answer.
  4. The manufacturer of the pesticide

Explanation

The certified applicator is responsible for complying with label directions and applicable regulations during the application. Clients, manufacturers, and suppliers have other duties but do not assume the applicator's compliance responsibility.

Question 23Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

Which situation would most likely require the applicator to consult Nevada state rules in addition to the federal label?

  1. When the product is being stored rather than applied
  2. When the label already states everything needed for any state
  3. When the applicator is applying a general-use product at home
  4. When state rules impose additional restrictions or requirements on the product or application Correct answer.

Explanation

States may impose requirements beyond the federal label, and applicators must comply with both. The label alone may not reflect state-specific restrictions, and state rules can apply to storage and general-use products as well.

Question 24Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

An applicator reads a label statement that says "Do not apply when wind speed exceeds 10 mph." This statement is best understood as:

  1. A recommendation that can be waived by the applicator
  2. A guideline that applies only to aerial application
  3. A suggestion for optimal results only
  4. A mandatory use restriction that must be followed Correct answer.

Explanation

Label statements that set conditions of use are enforceable restrictions, not mere suggestions. Applicators may not waive them, and they apply to the labeled methods of application.

Question 25Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

Which of the following best describes the concept of "direct supervision" for restricted use pesticides under FIFRA?

  1. The uncertified person may apply without any communication with the certified applicator
  2. The uncertified person may apply whenever the certified applicator is in the same county
  3. The certified applicator is responsible for and able to direct the application, with the level of oversight defined by label and state rules Correct answer.
  4. The certified applicator must physically perform every application personally

Explanation

Direct supervision means the certified applicator is responsible for the application and can direct the person applying, with specific oversight requirements set by the label and state rules. It does not require physical performance of every application, nor does it permit unsupervised use.

Question 26Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

Under FIFRA, which action is required before a pesticide product may be legally sold in interstate commerce?

  1. Registration of the product with the EPA Correct answer.
  2. Approval of the product by the state in which it is manufactured
  3. Certification of the product by the U.S. Department of Agriculture
  4. Listing of the product in the Federal Insecticide Register

Explanation

FIFRA requires that a pesticide be registered with the EPA before it is distributed or sold in interstate commerce, and the registered label defines lawful use. State approvals and other agency listings do not substitute for federal registration.

Question 27Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

A pesticide label carries the signal word DANGER along with a skull-and-crossbones symbol. What does this combination indicate?

  1. The product is highly toxic by the oral, dermal, or inhalation route Correct answer.
  2. The product is exempt from child-resistant packaging rules
  3. The product is a general-use formulation with no special hazards
  4. The product causes only mild eye irritation

Explanation

The signal word DANGER reflects the highest acute toxicity category, and the skull-and-crossbones pictogram specifically flags acute toxicity hazard. Products in this category carry the strongest precautionary statements on the label.

Question 28Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

An applicator plans to apply a registered product in a manner that is consistent with the label directions but that is prohibited by a Nevada statute. How should the applicator proceed?

  1. Proceed, because label directions always control over state law
  2. Follow the more restrictive state requirement and avoid the prohibited practice Correct answer.
  3. Apply only under the direct supervision of a state inspector
  4. Proceed, because FIFRA registration preempts conflicting state restrictions

Explanation

FIFRA allows states to impose requirements that are more restrictive than the federal label, so an applicator must comply with both the label and applicable state law. Where state law forbids a practice the label allows, the practice must be avoided.

Question 29Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

A restricted use pesticide is sold to a certified applicator, and the product will be applied by a noncertified employee working under that applicator. Which condition must be met for this arrangement to be lawful?

  1. The noncertified employee must complete a federal registration exam
  2. The certified applicator must be physically present at every application
  3. The noncertified employee must be under the direct supervision of the certified applicator Correct answer.
  4. The noncertified employee must hold a separate dealer license

Explanation

FIFRA permits restricted use pesticides to be applied by a noncertified person only when acting under the direct supervision of a certified applicator, as defined by the label and applicable rules. Physical presence is not always required unless the label or state rule specifies it.

Question 30Pesticide Laws, Regulations, and Labeling (federal FIFRA and Nevada state requirements)

An applicator is cited for applying a registered pesticide in a way that is inconsistent with its labeling. Under FIFRA, which statement best characterizes the legal status of such an application?

  1. It is a violation of federal law and may also violate Nevada law Correct answer.
  2. It is lawful if the applicator holds a valid Nevada certification
  3. It is lawful if the deviation was unintentional
  4. It is lawful because the product itself is federally registered

Explanation

FIFRA makes it unlawful to use a registered pesticide in a manner inconsistent with its labeling, and Nevada law separately prohibits labeled-use violations. Registration of the product or possession of a certification does not authorize off-label use.

Question 31Pesticide Safety, Human Health, and Personal Protective Equipment

Which signal word must appear on the label of a pesticide classified as highly toxic by the EPA?

  1. CAUTION
  2. NOTICE
  3. DANGER Correct answer.
  4. WARNING

Explanation

EPA toxicity categories I and II use the signal words DANGER and WARNING respectively, with DANGER reserved for the most acutely toxic products. CAUTION marks the lower-toxicity categories, and NOTICE is not a pesticide signal word.

Question 32Pesticide Safety, Human Health, and Personal Protective Equipment

A handler is mixing a concentrated liquid concentrate. Which glove material generally provides the best chemical resistance for this task?

  1. Cotton gloves
  2. Leather gloves
  3. Latex surgical gloves
  4. Nitrile gloves Correct answer.

Explanation

Nitrile and butyl rubber gloves resist many solvents and are commonly recommended for handling pesticide concentrates. Cotton and leather absorb liquids and hold them against the skin, and thin latex offers limited chemical protection.

Question 33Pesticide Safety, Human Health, and Personal Protective Equipment

Under the Worker Protection Standard, how soon after a pesticide application must a treated area be posted with warning signs if the labeling requires posting?

  1. Within 4 hours of the application
  2. Before workers next enter the field
  3. Within 24 hours of the application
  4. Before the application begins Correct answer.

Explanation

When labeling requires posted warning signs, the signs must be in place before the application starts so no worker can enter without seeing the warning. Posting after the application would leave a gap when the area is already contaminated.

Question 34Pesticide Safety, Human Health, and Personal Protective Equipment

A pesticide label states 'Causes irreversible eye damage.' Which eye protection does the label require for handlers?

  1. Sunglasses
  2. Safety glasses with side shields
  3. No eye protection if a hat is worn
  4. Goggles or a face shield Correct answer.

Explanation

Labels carrying the irreversible eye damage statement require protective eyewear such as goggles or a full face shield. Safety glasses alone do not seal against splashes, and ordinary sunglasses provide no chemical protection.

Question 35Pesticide Safety, Human Health, and Personal Protective Equipment

Which route of exposure accounts for most acute pesticide poisonings among agricultural workers?

  1. Inhalation of vapors
  2. Absorption through the eyes
  3. Absorption through the skin Correct answer.
  4. Ingestion of contaminated food

Explanation

Dermal absorption is the most common route of occupational pesticide exposure because contaminated clothing, splashes, and residues contact skin for extended periods. Inhalation and ingestion are less frequent routes in field and mixing work.

Question 36Pesticide Safety, Human Health, and Personal Protective Equipment

A worker feels dizzy and nauseated after spraying an organophosphate insecticide. What should be done first?

  1. Give the worker milk to drink
  2. Have the worker lie down in the treated field
  3. Move the worker to fresh air and call for medical help Correct answer.
  4. Wait to see if symptoms improve

Explanation

The first response to suspected pesticide poisoning is to remove the person from exposure and get medical assistance, bringing the label for the physician. Giving food or drink or delaying care can worsen the outcome.

Question 37Pesticide Safety, Human Health, and Personal Protective Equipment

Which statement describes the purpose of the reentry interval (REI) on a pesticide label?

  1. It is the shelf life of the mixed spray
  2. It is the time before the product may be applied again
  3. It is the minimum time workers may not enter the treated area Correct answer.
  4. It is the time required for the residue to wash off in rain

Explanation

The restricted-entry interval is the period after application during which entry into the treated area is prohibited without required protections. It protects workers from residues while they are still at hazardous levels.

Question 38Pesticide Safety, Human Health, and Personal Protective Equipment

A handler must wear a respirator while applying a pesticide. Which statement is true about respirator use?

  1. Any dust mask is acceptable if it fits loosely
  2. A respirator is only needed in enclosed spaces
  3. Respirators may be shared without cleaning
  4. The respirator must be fit-tested and the user trained Correct answer.

Explanation

Respirator use requires fit testing, medical evaluation, and training under the respiratory protection standard, and the device must match the label's specified type. Sharing uncleaned respirators or using a non-protective dust mask does not meet the requirement.

Question 39Pesticide Safety, Human Health, and Personal Protective Equipment

Which symptom is characteristic of cholinesterase inhibition from organophosphate or carbamate exposure?

  1. Blurred vision and excessive salivation Correct answer.
  2. Increased appetite
  3. Loss of hearing
  4. Peeling skin on the hands

Explanation

Cholinesterase inhibitors cause a cholinergic syndrome that includes pinpoint pupils, blurred vision, excessive salivation, sweating, and nausea. Hearing loss, skin peeling, and increased appetite are not typical signs.

Question 40Pesticide Safety, Human Health, and Personal Protective Equipment

Which practice best prevents pesticide contamination of the home from work clothing?

  1. Washing work clothes separately and showering before going home Correct answer.
  2. Wearing work clothes home and changing there
  3. Storing work clothes in the bedroom
  4. Washing work clothes with family laundry

Explanation

Work clothing should be laundered separately from household laundry, and handlers should shower and change before leaving the site to avoid carrying residues home. Mixing contaminated clothing with family laundry can transfer residues to other garments.

Question 41Pesticide Safety, Human Health, and Personal Protective Equipment

Which statement about the acute toxicity categories on pesticide labels is correct?

  1. Category I products carry the signal word CAUTION
  2. Signal words reflect the lowest toxicity found among all exposure routes
  3. Signal word assignment is based on the most severe toxicity among the tested routes Correct answer.
  4. Signal words are chosen by the manufacturer without EPA criteria

Explanation

EPA assigns a toxicity category based on the most severe effect observed across oral, dermal, inhalation, and irritation studies. The signal word reflects that worst-case category, not an average or the mildest result.

Question 42Pesticide Safety, Human Health, and Personal Protective Equipment

A label requires chemical-resistant gloves but lists no specific material. Which action is most appropriate?

  1. Skip gloves if the application is brief
  2. Consult the label or a pesticide safety reference for a suitable material Correct answer.
  3. Use any glove available at the farm supply store
  4. Use leather gloves because they are durable

Explanation

When the label does not name a material, the handler should use a reference such as the manufacturer's guidance or a chemical-resistance chart to select a suitable glove. Any glove, leather, or no glove at all does not satisfy the requirement.

Question 43Pesticide Safety, Human Health, and Personal Protective Equipment

Which action is required before a handler may enter a treated area during the restricted-entry interval to perform an emergency repair?

  1. The handler must wait until the REI ends
  2. The handler must apply water to the area first
  3. No special action is required if the repair is quick
  4. The handler must be provided the required PPE and information about the application Correct answer.

Explanation

Limited early-entry exceptions require the handler to be supplied with the PPE specified on the label and to be informed of the pesticide, its location, and the REI. A quick repair does not waive these protections.

Question 44Pesticide Safety, Human Health, and Personal Protective Equipment

Which factor most increases the risk of pesticide absorption through the skin?

  1. Wearing a long-sleeved shirt
  2. Applying in the early morning
  3. Hot weather causing sweating Correct answer.
  4. Wearing a wide-brimmed hat

Explanation

Heat and sweating increase skin absorption because sweat and moisture can dissolve residues and keep them against the skin, and hot conditions also encourage workers to remove PPE. A hat and long sleeves reduce exposure rather than increase it.

Question 45Pesticide Safety, Human Health, and Personal Protective Equipment

What information should be available at the worksite for emergency medical personnel?

  1. Only the name of the farm owner
  2. The application invoice
  3. The pesticide label and safety data sheet Correct answer.
  4. The weather forecast

Explanation

Medical responders need the product label and safety data sheet to identify the active ingredient and appropriate treatment. Site-specific emergency information should be accessible whenever pesticides are handled.

Question 46Pesticide Safety, Human Health, and Personal Protective Equipment

A pesticide label states 'Poisonous if swallowed, inhaled, or absorbed through skin.' Which statement best describes the required protective clothing?

  1. Ordinary work clothes are sufficient
  2. Only a face mask is needed
  3. Protective clothing covering the body plus the label-specified PPE must be worn Correct answer.
  4. Gloves alone are sufficient

Explanation

When a label warns of multiple exposure routes, the handler must wear all PPE specified by the label, including body-covering clothing and any gloves, footwear, or respiratory protection listed. Partial protection leaves other routes open.

Question 47Pesticide Safety, Human Health, and Personal Protective Equipment

Which statement about first aid for pesticide on the skin is correct?

  1. Apply oil to the skin to dilute the pesticide
  2. Wash immediately with soap and water and remove contaminated clothing Correct answer.
  3. Wait until symptoms appear before washing
  4. Cover the area tightly with plastic

Explanation

Dermal exposure should be addressed immediately by removing contaminated clothing and washing thoroughly with soap and water. Oils, occlusive coverings, and waiting for symptoms allow continued absorption.

Question 48Pesticide Safety, Human Health, and Personal Protective Equipment

Which of the following is a sign of heat stress that can be confused with pesticide illness?

  1. Broken bone
  2. Rash from poison ivy
  3. Sneezing
  4. Dizziness and nausea Correct answer.

Explanation

Heat stress and pesticide poisoning share overlapping signs such as dizziness, headache, nausea, and weakness, which is why handlers working in hot PPE must be monitored. The other listed conditions are unrelated to heat or pesticide exposure.

Question 49Pesticide Safety, Human Health, and Personal Protective Equipment

What is the purpose of the medical evaluation before a handler uses a respirator?

  1. To test the handler's knowledge of the label
  2. To determine pesticide application rates
  3. To select the color of the respirator
  4. To confirm the handler can safely wear a respirator Correct answer.

Explanation

The respiratory protection standard requires a medical evaluation to determine whether an employee is physically able to wear a respirator. It does not set application rates or assess label knowledge.

Question 50Pesticide Safety, Human Health, and Personal Protective Equipment

A handler notices a strong pesticide odor inside a closed storage building. Which action is most appropriate?

  1. Leave the area, ventilate, and investigate the source Correct answer.
  2. Light a match to check for fumes
  3. Put on a dust mask and stay
  4. Continue working until the task is finished

Explanation

A strong odor in an enclosed space suggests vapor accumulation, so the handler should exit, ventilate the area, and identify the source before reentering. Continuing work, using a flame, or relying on a dust mask risks inhalation exposure.
