Sample Questions
Try a few questions to see what the full exam is like.
A cleanup site has drums marked "flammable," an oxygen meter reading of 20.9 percent, and a combustible gas indicator reading of 7 percent LEL near a sump. The foreman says the oxygen reading proves the atmosphere is safe. What is the best hazard recognition response?
A treatment unit at a permitted TSD facility has a fixed deluge system, alarms, and a contingency plan. Employees are expected only to evacuate and call the plant emergency team if a major release occurs. What training distinction matters?
A project uses a water spray to suppress dust, but runoff begins carrying contaminated sediment toward the decon corridor. What adjustment best reflects control balancing?
An employer bought a commercial online 40-hour HAZWOPER course and asks the instructor to issue certificates immediately after the last module. No supervised field experience has occurred yet. What should the instructor do?
A sampling plan for contaminated sediment says to collect grab samples at the easiest shoreline locations. Historical maps show an old outfall, and field screening is highest in soft sediment near the outfall. Which characterization problem is most serious?
