BGE Safety Procedures & PPE 3 — Questions and Answers
Question 1: Which arc flash PPE category is required for tasks with an incident energy level between 4 and 8 cal/cm²?
- Category 0
- Category 1
- Category 2 (Correct answer)
- Category 3
Correct answer: Category 2
NFPA 70E Category 2 PPE (minimum 8 cal/cm² arc rating) is required for incident energies between 4 and 8 cal/cm².
Question 2: A BGE field crew smells natural gas while working in a neighborhood. What is their first priority?
- Identify the leak source immediately
- Evacuate the area and call 911 and BGE emergency line (Correct answer)
- Check all meters in the area
- Ventilate nearby buildings
Correct answer: Evacuate the area and call 911 and BGE emergency line
Life safety comes first — evacuate and call emergency services before any investigation or repair attempts.
Question 3: What does IDLH stand for in the context of confined space entry?
- Immediately Dangerous to Life or Health (Correct answer)
- Internal Detection Level Hazard
- Incident Data Log for Hazards
- Industrial Default Limit for Hydrocarbons
Correct answer: Immediately Dangerous to Life or Health
IDLH (Immediately Dangerous to Life or Health) defines atmospheric concentrations that pose an immediate threat requiring escape.
Question 4: When must a Job Hazard Analysis (JHA) be completed for BGE field work?
- Only for new types of tasks
- Before starting any task each day (Correct answer)
- Only when a supervisor requests it
- After the job is complete for documentation
Correct answer: Before starting any task each day
A JHA must be completed before beginning work each day to identify hazards and determine required controls.
Question 5: What is the correct hand signal when a spotter wants a vehicle operator to stop immediately?
- Both arms extended horizontally
- One fist raised overhead
- Arms crossed overhead in an X shape (Correct answer)
- Both palms facing downward and lowered
Correct answer: Arms crossed overhead in an X shape
Arms crossed above the head in an X is the universal stop signal for vehicle operations in utility work zones.
Question 6: Which respiratory protection is required when entering a space with hydrogen sulfide (H2S) concentration above IDLH?
- N95 disposable respirator
- Half-face air-purifying respirator
- Self-contained breathing apparatus (SCBA) (Correct answer)
- Powered air-purifying respirator (PAPR)
Correct answer: Self-contained breathing apparatus (SCBA)
SCBA is required for IDLH atmospheres because air-purifying respirators cannot protect against immediately dangerous concentrations.
Question 7: A BGE crew is working in a street excavation at night. What minimum safety requirement must be in place?
- One orange cone per lane
- High-visibility vests only
- A complete traffic control plan with lighting, barricades, and flaggers (Correct answer)
- A written notice to nearby residents
Correct answer: A complete traffic control plan with lighting, barricades, and flaggers
Night excavation work requires a full traffic control plan including adequate lighting, barricades, and trained flaggers per MUTCD standards.
