AERA Safety Standards & Environmental Compliance 5

Question 1

A shop uses a solvent recycling unit to reclaim chlorinated degreaser on-site. Under RCRA, the reclaimed solvent is generally:

Accepted Answer

Excluded from hazardous waste rules if legitimately reclaimed for reuse

Answer

Solvents reclaimed on-site and reused in the same process are excluded from RCRA hazardous waste regulations under the reclamation exclusion when legitimately recycled.

Question 2

Which engineering control is most effective at reducing a machine operator's exposure to airborne metal particles generated during cylinder boring?

Accepted Answer

Local exhaust ventilation (LEV) capturing dust at the source

Answer

Local exhaust ventilation captures contaminants at their source before they disperse into the work environment, making it the most effective engineering control.

Question 3

When is an engine rebuilding shop REQUIRED to submit a Tier II chemical inventory report under EPCRA Section 312?

Accepted Answer

When hazardous chemicals are stored at or above OSHA threshold quantities

Answer

EPCRA Section 312 Tier II reporting is required when covered hazardous chemicals are present on-site at or above the 10,000-pound (or lower EHS) reporting threshold at any point during the year.

Question 4

What is the primary purpose of a Job Hazard Analysis (JHA) conducted before an engine rebuild procedure?

Accepted Answer

To systematically identify hazards and determine controls for each job step

Answer

A JHA breaks a job into steps, identifies hazards at each step, and specifies controls, making it a core proactive safety planning tool.

Question 5

Shops that perform chrome plating on engine components are regulated under the Clean Air Act NESHAP for chromium emissions. The primary health hazard driving this regulation is:

Accepted Answer

Hexavalent chromium (Cr VI) being a known human carcinogen

Answer

Hexavalent chromium (Cr VI) generated during hard chrome plating is classified as a known human carcinogen by IARC and EPA, driving strict NESHAP emission controls.
