CHMM Planning for Hazardous Materials 4

Question 1

Which document is the primary source used to determine isolation distances and protective action distances during a hazardous materials highway or rail incident?

Accepted Answer

Emergency Response Guidebook (ERG)

Answer

The ERG, published by PHMSA, DOT Canada, and Mexico's SCT, provides first responders with initial isolation and protective action distances for hazmat incidents.

Question 2

In OSHA's PSM standard (29 CFR 1910.119), the Management of Change (MOC) procedure is required when:

Accepted Answer

Changes are made to technology, equipment, procedures, or facilities involving covered processes (except like-for-like replacements)

Answer

MOC requires formal review and authorization before any change — except replacement-in-kind — to ensure process safety is not compromised.

Question 3

A community's emergency response plan should include a notification chain that contacts which entities when a reportable hazardous materials release occurs?

Accepted Answer

The LEPC, State Emergency Response Commission, National Response Center, and local responders as appropriate

Answer

Regulatory requirements under EPCRA and CERCLA mandate notification of the NRC, SERC, and LEPC in addition to local emergency responders for reportable releases.

Question 4

Which planning tool uses atmospheric dispersion modeling to predict the concentration and movement of airborne chemical releases?

Accepted Answer

CAMEO/ALOHA

Answer

ALOHA (Areal Locations of Hazardous Atmospheres), part of the CAMEO suite, models the dispersion of airborne chemical releases to estimate affected areas.

Question 5

Under EPA's Risk Management Program (RMP), a Program 3 process is subject to the most stringent requirements, which include:

Accepted Answer

Prevention program including PHA, MOC, pre-startup safety review, and mechanical integrity checks

Answer

Program 3 applies PSM-equivalent prevention requirements including PHA, MOC, mechanical integrity, and pre-startup safety reviews for the highest-risk processes.
