CHST CHST - Construction Health and Safety Technician Emergency and Fire Preparedness Questions and Answers 4 — Questions and Answers
Question 1: When performing a Job Hazard Analysis (JHA) for emergency scenarios, which element is most critical to address for multi-story construction projects?
- Noise levels during evacuation
- Vertical evacuation routes and stairwell integrity (Correct answer)
- Color coding of emergency signs
- Proximity of the nearest hospital
Correct answer: Vertical evacuation routes and stairwell integrity
Multi-story construction requires specific attention to safe vertical evacuation paths since elevators cannot be used during fires.
Question 2: Which OSHA standard requires construction employers to develop and implement an Emergency Action Plan (EAP)?
- 29 CFR 1926.35 (Correct answer)
- 29 CFR 1926.150
- 29 CFR 1910.38
- 29 CFR 1926.403
Correct answer: 29 CFR 1926.35
29 CFR 1926.35 is the OSHA construction standard that mandates Emergency Action Plans for covered construction employers.
Question 3: What type of fire suppression system is most commonly required in partially enclosed construction areas where sprinklers are temporarily out of service?
- Halotron system
- Standpipe system
- Temporary fire watch with extinguishers (Correct answer)
- Dry chemical fixed system
Correct answer: Temporary fire watch with extinguishers
When sprinkler systems are impaired during construction, a temporary fire watch must be established until the system is restored.
Question 4: In the context of construction site emergency planning, what does the term 'impairment' refer to?
- A worker affected by substances during an emergency
- Any condition that renders a fire protection system inoperable or reduced (Correct answer)
- Structural damage caused by a fire event
- Lack of proper PPE during emergency response
Correct answer: Any condition that renders a fire protection system inoperable or reduced
Impairment refers to any condition—planned or unplanned—that takes a fire protection system out of normal service.
Question 5: During a mass casualty incident on a construction site, the START triage system classifies a victim who is breathing but has a respiratory rate above 30 breaths per minute as which color tag?
- Green
- Yellow
- Red (Correct answer)
- Black
Correct answer: Red
The START triage system tags patients red (immediate) if respirations exceed 30 per minute, indicating critical need for intervention.
Question 6: What is the minimum number of emergency telephone numbers that must be posted at a construction site job site per OSHA requirements under 29 CFR 1926.35?
- One (911 only)
- Two
- Three (fire, ambulance, police)
- No specific number required, but the EAP must define notification methods (Correct answer)
Correct answer: No specific number required, but the EAP must define notification methods
OSHA 1926.35 requires an EAP to include notification methods but does not specify a minimum count of posted numbers; the plan must define the procedures.
Question 7: A construction site emergency action plan must be reviewed with each employee when which condition occurs?
- Quarterly, regardless of changes
- Only upon initial hire
- When the plan is developed, when responsibilities change, or when the plan changes (Correct answer)
- Only after a fire or emergency incident
Correct answer: When the plan is developed, when responsibilities change, or when the plan changes
OSHA requires EAP review upon plan creation, when employee responsibilities change, or when the plan itself is revised.
