PO Emergency Response & Incident Management 2

Question 1

What does the Emergency Response Guide (ERG) provide to first responders?

Accepted Answer

Initial guidance on hazards, protective actions, and safe distances for incidents involving hazardous materials

Answer

The ERG provides first responders with quick-reference information on chemical hazards, isolation distances, and protective actions during transportation and fixed-site incidents.

Question 2

What is the purpose of a Process Hazard Analysis (PHA)?

Accepted Answer

To systematically identify and evaluate potential hazards in a process to prevent accidents

Answer

A PHA is a structured, team-based evaluation of process hazards and consequences, required under OSHA PSM regulation 1910.119, to develop risk reduction measures.

Question 3

During an uncontrolled gas release, wind direction is critical because operators should:

Accepted Answer

Evacuate crosswind and upwind to stay out of the path of the migrating vapor cloud

Answer

Wind carries a vapor cloud downwind; evacuating crosswind or upwind keeps responders out of the hazardous plume.

Question 4

What is a 'shelter in place' directive used for during a process plant emergency?

Accepted Answer

Directing personnel to move indoors, seal the building, and await further instructions when outdoor evacuation is more dangerous

Answer

Shelter in place protects personnel from an outdoor toxic release by using the building as a barrier when evacuating through the affected area would increase exposure.

Question 5

What is 'near-miss' reporting and why is it critical in process safety culture?

Accepted Answer

Documenting incidents that had the potential to cause harm but did not, to identify and fix underlying hazards

Answer

Near-miss reporting reveals hazardous conditions before they cause injury or loss, enabling corrective action and building a proactive safety culture.
