OSHA HAZWOPER 24-Hour Hazardous Waste Operations and Emergency Response Practice
Exam
10-Line Exam Coverage in Points Form
1. Regulatory Foundation – 29 CFR 1910.120 (HAZWOPER) ; primary purpose: protect
workers involved in hazardous waste operations and emergency response ; covers
cleanup, treatment, storage, and disposal; employer must maintain Emergency
Response Plan ; training documentation required (certificates/attendance)
2. Training Levels – 24-Hour: occasional or limited exposure workers (support roles) ; 40-
Hour: frequent exposure/full cleanup workers ; 8-Hour Refresher: annual renewal ; 8-
Hour Supervisor: additional supervisor training
3. Responder Levels – Awareness: recognition only; Operations: defensive containment;
Technician: offensive entry and stop releases; Incident Commander: overall command ;
offensively trained and equipped entry into hot zone requires Technician level
4. Site Control Zones – Hot Zone: immediate contamination/highest risk ; Warm Zone:
decontamination corridor ; Cold Zone: command/support (safest)
5. PPE Levels – Level A: highest protection (fully encapsulated + SCBA) for unknown
vapors/toxic gases ; Level B: highest respiratory (SCBA) + splash protection; Level C: APR
+ chemical-resistant clothing; Level D: basic work uniform
6. Hazard Recognition – Chemical, biological, radiological hazards ; Safety Data Sheets
(SDS) identify hazards/PPE ; benzene = hematologic toxicity ; pyrophoric = spontaneous
ignition in air
7. Exposure & Toxicology – Routes: inhalation (primary for gases), skin absorption,
ingestion, injection ; acute vs. chronic effects ; IDLH = Immediate Danger to Life or
Health ; NIOSH sets RELs; OSHA sets PELs
8. Incident Command System (ICS) – Primary goal: responder safety and coordination ;
Safety Officer monitors hazards and responder safety ; ERG (DOT publication) provides
initial guidance ; Incident Commander coordinates response
9. Decontamination – Warm Zone is where decontamination occurs ; water rinse for water-
soluble chemicals ; decontamination corridor = controlled area for safe removal ; vapor
suppression reduces airborne hazards

10. Spill Control & Containment – Primary goal: confine and limit spread ; immediate
priority: personnel safety ; evacuation and reporting are initial actions ; offensive entry
requires technician training + proper PPE
COMPREHENSIVE PRACTICE QUESTIONS (1-250)
Section 1: Regulatory Foundation & Standards (1-25)
1. Which OSHA standard governs HAZWOPER training requirements?
A. OSHA 29 CFR 1910.147
B. OSHA 29 CFR 1910.132
C. OSHA 29 CFR 1910.120
D. OSHA 29 CFR 1926.502
Answer: C
Rationale: OSHA 29 CFR 1910.120 specifically addresses Hazardous Waste Operations and
Emergency Response (HAZWOPER). This is the foundational standard that establishes training
requirements for workers at hazardous waste sites and emergency responders . Options A
(Lockout/Tagout), B (Personal Protective Equipment), and D (Fall Protection) are different OSHA
standards covering different workplace hazards.
2. What is the primary purpose of the OSHA HAZWOPER standard?
A. To regulate industrial hygiene in office environments
B. To provide a general workplace safety program for all employees
, Page 3 of 113
C. To protect workers involved in hazardous waste operations and emergency response
D. To enforce fire prevention protocols in chemical facilities
Answer: C
Rationale: HAZWOPER (29 CFR 1910.120) is specifically designed to protect employees working
with hazardous substances during cleanup, treatment, storage, and emergency response. It
does not cover general workplace safety in offices, routine industrial hygiene, or fire prevention
alone . The standard was developed to address the unique hazards of hazardous waste sites and
emergency chemical releases.
3. A HAZWOPER 24-hour course is designed for which worker category?
A. Full-time hazardous waste site managers
B. Workers with occasional or limited exposure to hazardous substances
C. Hospital emergency physicians
D. Administrative office staff with no site access
Answer: B
Rationale: The 24-hour HAZWOPER course is designed for employees who may enter hazardous
sites occasionally but are not routinely exposed to high-risk conditions . Workers with frequent
exposure require the 40-hour course, and managers/supervisors require additional training .
The 24-hour course includes 24 hours of classroom/training plus 1 day of supervised field
experience.
4. Which document is required to document HAZWOPER training compliance?
, Page 4 of 113
A. Employee vacation logs
B. Daily lunch schedules
C. Training completion certificates and attendance records
D. Payroll records
Answer: C
Rationale: OSHA mandates documentation of HAZWOPER training for regulatory compliance
and audits. Training completion certificates and attendance records demonstrate that workers
have received the required training . Employers must maintain these records to show
compliance with 29 CFR 1910.120, as training is a key component of the standard.
5. What is the minimum training requirement for a HAZWOPER Technician-level responder?
A. 8 hours
B. 16 hours
C. 24 hours
D. 40 hours
Answer: C
Rationale: Technician-level responders must complete at least 24 hours of training, as specified
in 29 CFR 1910.120 . This training qualifies them to perform offensive entry into the hot zone
and actively intervene to stop releases. Awareness-level responders require 8 hours, and
Operations-level responders require 16 hours.
6. Which responder level is responsible for stopping the release of hazardous substances?
