SHS Emergency Response & Preparedness 4

Question 1

Which Personal Protective Equipment (PPE) level provides the highest respiratory and skin protection during a chemical emergency response?

Accepted Answer

Level A with fully encapsulating vapor-protective suit

Answer

Level A PPE, which includes a fully encapsulating vapor-protective suit with SCBA, provides the highest level of respiratory and skin protection.

Question 2

A chemical spill releases a vapor with a vapor density greater than 1.0. Where should responders avoid establishing a command post?

Accepted Answer

In low-lying areas, basements, or confined spaces near the release

Answer

Vapors with a density greater than 1.0 are heavier than air and will collect in low-lying areas, basements, and confined spaces, creating explosion or asphyxiation hazards.

Question 3

Under the Emergency Planning and Community Right-to-Know Act (EPCRA), facilities must notify the Local Emergency Planning Committee (LEPC) when they have Extremely Hazardous Substances (EHS) at or above what threshold?

Accepted Answer

Threshold Planning Quantity (TPQ) or 500 pounds, whichever is less

Answer

EPCRA Section 302 requires facilities to notify the LEPC if they possess an EHS at or above its Threshold Planning Quantity or 500 pounds, whichever is less.

Question 4

An employee is found unconscious in a confined space suspected to contain hydrogen sulfide. What is the CORRECT first action for a would-be rescuer?

Accepted Answer

Don appropriate PPE and SCBA before attempting entry

Answer

Rescuers must don appropriate respiratory protection (SCBA) and PPE before entering a space suspected of containing IDLH atmospheres to prevent becoming additional victims.

Question 5

The 'all-hazards' approach to emergency preparedness is advantageous primarily because it:

Accepted Answer

Builds capabilities applicable across a wide range of potential incidents
