CHMM Facility Operations with Hazmat 5

Question 1

A facility manager discovers that drums containing hazardous waste have been stored in a satellite accumulation area (SAA) for more than 60 days. Under 40 CFR 262.15, this situation most likely indicates a violation because:

Accepted Answer

Drums at an SAA must be moved to the central accumulation area once the container limit is reached, regardless of time

Answer

SAAs are not subject to time limits per se, but containers must be moved once the volume limit (55 gallons for non-acute, 1 quart for acute) is reached—a long accumulation time suggests containers have exceeded limits.

Question 2

Under 40 CFR Part 264 Subpart I, hazardous waste containers must be marked with the words 'Hazardous Waste' and with information that identifies the hazard. This marking requirement becomes effective:

Accepted Answer

When waste is first placed into the container

Answer

Containers must be marked as 'Hazardous Waste' from the moment waste is first added to them.

Question 3

A facility's chemical inventory includes a substance with an NFPA 704 diamond rating of Health=4, Flammability=0, Instability=1, Special=W with a slash through it (no water). This diamond most closely describes which type of hazard scenario?

Accepted Answer

A cryogenic liquid that reacts violently with water and is acutely toxic

Answer

Health 4 indicates a life-threatening chemical, Flammability 0 means non-combustible, Instability 1 means slightly unstable, and the W-bar means it reacts dangerously with water—consistent with certain cryogenic or water-reactive toxic materials.

Question 4

When a facility conducts a Management of Change (MOC) review for replacing a pump seal material in a sulfuric acid service line, which hazard analysis step must be completed BEFORE the change is implemented?

Accepted Answer

Evaluating whether the new seal material introduces new or different hazards to the process

Answer

MOC requires a pre-change hazard evaluation to determine if the change introduces new hazards, before implementation—not after.

Question 5

A hazardous materials manager is selecting personal protective equipment for workers cleaning up a spill of a highly toxic liquid with unknown vapor concentration. Following the OSHA Hazwoper framework, which PPE level should be selected as the initial entry level?

Accepted Answer

Level A — fully encapsulating vapor-protective suit with SCBA

Answer

When skin and vapor hazards are unknown or known to be severe, Level A provides the highest level of protection with a fully encapsulating suit and SCBA.
