32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Site Safety and Health Plan
A written document describing site hazards, controls, PPE, monitoring, decontamination, and emergency procedures, required before workers enter a HAZWOPER site.
Site Safety and Health Supervisor
The person responsible for implementing the site safety and health plan, conducting inspections, and halting work when imminent danger exists.
Hierarchy of Controls
A ranking of hazard controls from most to least effective: elimination, substitution, engineering controls, administrative controls, and personal protective equipment.
Imminent Danger
A condition posing an immediate risk of serious harm or death, requiring immediate work stoppage and evacuation until the hazard is controlled.
Hazard Communication Program
A written program requiring a chemical inventory, safety data sheets, container labeling, and employee training on site chemical hazards.
Site Characterization
The process of gathering information on site history, contaminants, and physical hazards to guide PPE selection, monitoring, and decontamination planning.
Preliminary Site Evaluation
An initial assessment using records review, site reconnaissance, and interviews to identify likely contaminants and hazards before sampling begins.
Photoionization Detector
A real-time field instrument using ultraviolet light to ionize and screen for volatile organic compounds in air, reported in parts per million.
Detection Limit
The lowest concentration an instrument or method can reliably measure; it must be below the action level being evaluated.
Sampling Plan
A document specifying analytes, methods, detection limits, sample locations, and quality control procedures such as blanks and duplicates.
Exclusion Zone
The contaminated area where hazardous conditions exist; only authorized personnel in appropriate PPE may enter and must sign in and out.
Contamination Reduction Zone
The transition area between the exclusion and support zones containing decontamination stations where workers remove contaminated PPE.
Support Zone
The uncontaminated area containing command, staging, and administrative functions where PPE is normally not required.
Buddy System
A rule requiring that no worker enter the exclusion zone alone; a partner and backup person must be available for rescue.
Site Control Log
A record documenting who enters and exits the exclusion zone, the time of entry and exit, and the PPE worn.
40-Hour General Site Worker
A worker who may disturb contaminated material and must complete 40 hours of instruction plus 3 days of supervised field experience.
24-Hour Occasional Site Worker
A worker who enters sites only occasionally and does not disturb contamination, requiring 24 hours of instruction and 1 day of field experience.
8-Hour Annual Refresher
The required yearly refresher training for all HAZWOPER-trained workers to maintain competency and stay current on hazards and procedures.
Supervisor Training
An additional 8 hours of specialized training beyond the 40-hour course, required for managers and supervisors of hazardous waste operations.
Site-Specific Training
Training provided to newly assigned workers covering the site safety and health plan, site hazards, PPE, and emergency procedures.
Level A PPE
The highest protection level: a fully encapsulating chemical-resistant suit with SCBA or supplied air, used for unknown or highly toxic hazards.
Level B PPE
Chemical-resistant clothing with SCBA or supplied air, providing the highest respiratory protection when skin protection needs are less severe.
Level C PPE
Chemical-resistant clothing with an air-purifying respirator, used only when contaminants are known and concentrations are below the respirator protection factor.
Assigned Protection Factor
The expected level of respiratory protection a properly fitted respirator provides, used to compare against maximum contaminant concentrations.
Oxygen Deficiency
An atmosphere containing less than 19.5 percent oxygen, requiring SCBA or supplied air before entry; never enter with an air-purifying respirator.
Decontamination
The process of removing or reducing contaminants from personnel, PPE, and equipment before leaving the exclusion zone to prevent spread.
Wet Decontamination
A method using water and detergent to wash contaminants from PPE and equipment, requiring containment and disposal of the resulting wastewater.
Medical Surveillance
A program of baseline and periodic medical exams for workers exposed above limits, respirator users, and HAZWOPER team members.
Medical Record Retention
The requirement to keep employee medical records for the duration of employment plus 30 years and provide access to the employee and physician.
Emergency Alarm
A signal that is audible and distinguishable from other site signals, used to alert workers to evacuate or take emergency action.
Assembly Point
A designated safe location where workers report after evacuation so that all personnel can be accounted for.
Respirator Fit Testing
A test, qualitative or quantitative, confirming a respirator seals properly; required before use and annually thereafter.
