Question 1

A substance is classified as a RCRA characteristic hazardous waste if it exhibits which characteristic?

Accepted Answer

Ignitability, corrosivity, reactivity, or toxicity (TCLP test)

Answer

RCRA characteristic hazardous waste must exhibit at least one of four characteristics: ignitability (flash point <60°C), corrosivity (pH <2 or >12.5), reactivity, or toxicity (TCLP leachate exceeds limits).

Question 2

Under OSHA's Occupational Exposure Limits (OELs), a 'ceiling value' means the concentration that:

Accepted Answer

Must never be exceeded at any time during the work shift

Answer

A ceiling value (C) is a concentration that must never be exceeded at any time, as opposed to PEL (8-hr TWA) or STEL (15-min short-term), because even brief exposures above the ceiling are considered immediately hazardous.

Question 3

SARA Title III (Emergency Planning and Community Right-to-Know Act, EPCRA) requires facilities to report chemical inventories to local emergency planners under:

Accepted Answer

All of the above are SARA Title III requirements

Answer

SARA Title III encompasses emergency planning (Section 302), chemical inventory reporting (Sections 311/312), and toxic chemical release reporting (Section 313 - TRI), all of which are mandatory compliance requirements.

Question 4

In OSHA's process safety management (PSM), a 'near miss' incident should be:

Accepted Answer

Investigated and documented as thoroughly as actual incidents to prevent future accidents

Answer

PSM requires incident investigation of near misses (events that could have caused catastrophic releases) because they represent opportunities to identify and correct hazards before actual injuries or releases occur.

Question 5

The Toxic Release Inventory (TRI) under SARA Section 313 requires reporting of:

Accepted Answer

Annual environmental releases and transfers of listed toxic chemicals above reporting thresholds

Answer

TRI (EPA Form R) requires annual reporting of releases and off-site transfers of ~770 listed toxic chemicals by facilities meeting employee count, industry sector, and quantity use thresholds.
