CIH study plan

Diagram the source-pathway-receptor exposure paradigm for three distinct workplace scenarios

Distinguish integrated (laboratory) sampling from direct-reading methods and justify a selection for a given agent

Compute 8-hour TWA, STEL, and excursion values from a set of consecutive sample results

Differentiate exposure from dose and list the physiological and behavioral factors that modify that relationship

Form similar exposure groups from a described workforce and justify the grouping logic

Apply upper-confidence-limit decision logic to decide whether an exposure is controlled

Rank a set of measured exposures against occupational exposure limits to set intervention priorities

List the hierarchy of controls and match at least one control to each route of entry

Calculate capture velocity, hood entry loss, and duct velocity for a local exhaust system

Size a dilution ventilation rate using the general ventilation equation for a solvent release

Select an assigned protection factor and cartridge type for a specified airborne contaminant

Compare engineering, administrative, and PPE options for a noise overexposure and defend the ranking

Evaluate control effectiveness for a scenario with simultaneous inhalation and dermal exposure

Sequence the four steps of health risk assessment and state the output of each

Interpret relative risk, odds ratio, and standardized mortality ratio and name their key limitations

Compare regulatory and consensus risk frameworks and their acceptable-risk ranges

Calculate non-carcinogenic hazard quotients and excess lifetime cancer risk from a supplied exposure scenario

Apply risk management frameworks such as ALARP and the precautionary principle to a decision point

Trace community exposure pathways through air, water, soil, and the food chain

Identify risk perception and outrage factors that shape community response to a hazard

Interpret dispersion modeling output and state at least three limitations of the model

Construct a budget justification linking an industrial hygiene program to avoided costs

Define scope, schedule, and stakeholder map for a cross-functional exposure-reduction project

Select program performance metrics and describe how an audit would verify them

Outline incident command roles and specify the industrial hygienist's duties during the response and recovery phases

Classify hazards and select protective equipment for three emergency response scenarios

Apply the code of ethics to conflicts involving data integrity, confidentiality, and competence

Distinguish obligations owed to the employer, the worker, and the public when they conflict

Complete a full-length timed practice exam under exam-day conditions

Re-work every item in the error log and state the corrected reasoning aloud

Recite key formulas and exposure limit relationships from memory without notes

Set a section pacing strategy and confirm exam-day logistics
