1. The main purpose of the HAZWOPER standard (29 CFR 1910.120) is to:
A. Regulate workers’ wages at hazardous waste sites
B. Control the sale of hazardous materials
C. Protect workers involved in hazardous waste operations and emergency
response
D. License hazardous waste disposal companies
Rationale: _HAZWOPER sets health and safety requirements for workers at
,hazardous waste sites and emergency responses to hazardous substance
releases._
2. HAZWOPER 40-hour training is required for workers who:
A. Occasionally visit offices near a hazardous waste site
B. Regularly work on hazardous waste cleanup operations with potential
exposure
C. Handle only office paperwork for hazardous waste sites
D. Respond only to fire alarms
Rationale: _General site workers with potential exposure during cleanup
operations must receive at least 40 hours of off-site training plus supervised field
experience._
3. The HAZWOPER standard applies to all of the following EXCEPT:
A. Hazardous waste site cleanup operations
B. Emergency response to hazardous substance releases
C. Operations at RCRA treatment, storage, and disposal facilities
D. Routine office work in a non-industrial setting
Rationale: _Routine office settings without hazardous waste operations are not
covered by HAZWOPER._ +1
,4. A site-specific Health and Safety Plan (HASP) must:
A. Be generic and the same for all sites
B. Identify site hazards, PPE, work practices, decon, and emergency procedures
C. Only list employee names and phone numbers
D. Be written only after an accident occurs
Rationale: _The HASP must be tailored to the site, describing hazards, controls,
PPE, decon, medical surveillance, and emergency response._
5. The primary purpose of a site characterization before work begins is to:
A. Estimate project cost
B. Identify types and levels of hazards so controls can be selected
C. Determine which contractor to hire
D. Decide worker pay rates
Rationale: _Site characterization gathers information on contaminants, locations,
and conditions to plan safe operations and PPE._
6. Which statement best describes the employer’s responsibility under
HAZWOPER?
A. Provide training only after an accident happens
B. Ensure adequate training, PPE, medical surveillance, and a written safety and
, health program
C. Let workers choose their own safety level
D. Allow workers to decline training if experienced
Rationale: _Employers must implement a safety and health program, training,
PPE, medical surveillance, and other protections._
7. The minimum passing score commonly required on HAZWOPER final exams by
many course providers is:
A. 50%
B. 60%
C. 70%
D. 90%
Rationale: _Many HAZWOPER 40 courses require at least 70% to pass, though
specific provider policies can vary._
8. Under HAZWOPER, workers must receive refresher training at least:
A. Every 2 years
B. Only when changing jobs
C. Annually
D. Every 5 years
