- 30 days
- 60 days
- 90 days (Correct answer)

Question 3: When conducting a Hazard and Operability (HAZOP) study at a facility, the term 'deviation' refers to which of the following?
- A departure from design intent identified by applying guide words to process parameters (Correct answer)
- An unplanned equipment failure recorded in the maintenance log
- A variance granted by a regulatory agency for process operation
- A difference between actual and target production yield
Correct answer: A departure from design intent identified by applying guide words to process parameters
In a HAZOP, deviations are identified by combining guide words (e.g., 'no,' 'more') with process parameters to find departures from design intent.
Question 4: Which document must a facility receiving hazardous chemicals in quantities above OSHA Hazard Communication thresholds maintain and make available to employees and local emergency planners under 29 CFR 1910.1200 and EPCRA Section 311?
- Emergency Response Guidebook (ERG)
- Safety Data Sheets (SDS) (Correct answer)
- Tier II report
- Process hazard analysis (PHA) summary
Correct answer: Safety Data Sheets (SDS)
Safety Data Sheets must be maintained on-site and provided to employees and, under EPCRA 311, submitted to local emergency planners.
Question 5: A facility stores 10,000 gallons of diesel fuel in an above-ground storage tank. Under EPA's Spill Prevention, Control, and Countermeasure (SPCC) rule, what is the minimum secondary containment volume required for a single tank?
- 50% of the tank's capacity
- 100% of the tank's capacity
- 110% of the tank's capacity (Correct answer)
- 125% of the tank's capacity
Correct answer: 110% of the tank's capacity
EPA SPCC regulations require secondary containment capable of holding 110% of the largest single tank's capacity.
Question 6: Under the NFPA 30 Flammable and Combustible Liquids Code, what is the maximum allowable size for a portable container used to store Class IA flammable liquids inside a facility?
- 1 gallon (Correct answer)
- 5 gallons
- 12 gallons
- 55 gallons
Correct answer: 1 gallon
NFPA 30 limits Class IA flammable liquid portable containers inside buildings to 1 gallon.
Question 7: A hazardous waste facility's contingency plan must designate an Emergency Coordinator. Under 40 CFR 264.55, during an emergency, the Emergency Coordinator must notify which entity first?
- The facility's corporate headquarters
- The Local Emergency Planning Committee (LEPC)
- The National Response Center (NRC) (Correct answer)
- The State environmental agency
Correct answer: The National Response Center (NRC)
The Emergency Coordinator must immediately notify the National Response Center of any release that could threaten human health or the environment.
