WPR Emergency Procedures 2 — Questions and Answers
Question 1: When a gas detector alarm sounds during hot work, the WPR must:
- Reduce the ignition source and continue monitoring
- Immediately cease all hot work, remove ignition sources, and evacuate the area (Correct answer)
- Reset the detector and continue work
- Call the lab to verify the detector reading
Correct answer: Immediately cease all hot work, remove ignition sources, and evacuate the area
A gas detector alarm during hot work signals an imminent explosion or fire risk, requiring immediate halt of all ignition activities and evacuation.
Question 2: What is the minimum information a WPR should provide when calling for emergency medical assistance?
- Only the victim's name
- Location, nature of injury/illness, number of victims, and any known hazards at the site (Correct answer)
- The permit number and issuer name
- The worker's employment status and health insurance information
Correct answer: Location, nature of injury/illness, number of victims, and any known hazards at the site
Emergency responders need location, victim condition, and hazard information to respond safely and effectively.
Question 3: An assembly point (muster area) is important because:
- It is where permits are stored
- It provides a safe, pre-designated location where all evacuated personnel can be accounted for (Correct answer)
- It is the area where emergency vehicles park
- It is the nearest exit from any building
Correct answer: It provides a safe, pre-designated location where all evacuated personnel can be accounted for
Assembly points allow headcounts to determine if anyone is missing, enabling targeted rescue without unnecessary entry into dangerous areas.
Question 4: If a spill of a hazardous chemical occurs during permitted work, the WPR's first obligation is to:
- Attempt to clean up the spill with available materials
- Stop work, evacuate the area, and notify the appropriate emergency and safety personnel (Correct answer)
- Document the spill and continue working from a distance
- Dilute the spill with water immediately
Correct answer: Stop work, evacuate the area, and notify the appropriate emergency and safety personnel
Chemical spills can create inhalation, fire, and explosion hazards requiring immediate evacuation and notification of trained hazmat responders.
Question 5: What is the significance of the 'buddy system' during emergency procedures in permit work?
- It assigns one experienced worker to mentor a new employee
- It ensures no worker is alone in a hazardous area, enabling faster detection and response to emergencies (Correct answer)
- It pairs workers to share one set of PPE
- It is a cost-saving measure for training programs
Correct answer: It ensures no worker is alone in a hazardous area, enabling faster detection and response to emergencies
The buddy system ensures someone is always present to recognize and respond to an emergency affecting another worker.
Question 6: OSHA requires that rescue personnel for confined space operations be:
- Any available worker on site
- Trained and equipped for the specific hazards of that confined space, either on-site or on call (Correct answer)
- Members of the local fire department only
- Certified emergency medical technicians (EMTs) only
Correct answer: Trained and equipped for the specific hazards of that confined space, either on-site or on call
OSHA 29 CFR 1910.146 mandates that rescue services be specifically trained and equipped for the hazards present in each confined space.
