DCI Safety Practices & Procedures 4 — Questions and Answers
Question 1: A technician is pulling cable through a conduit in a crawl space with less than 18 inches of clearance. Which confined space category likely applies?
- Non-permit required confined space
- Permit-required confined space (Correct answer)
- Open space with restricted access
- Class I Division 2 space
Correct answer: Permit-required confined space
Crawl spaces with limited entry/exit points and potential atmospheric hazards typically qualify as permit-required confined spaces under OSHA 1910.146.
Question 2: What is the maximum weight capacity that a standard Type II industrial stepladder (rated for commercial use) can support?
- 200 lbs
- 225 lbs
- 250 lbs (Correct answer)
- 300 lbs
Correct answer: 250 lbs
ANSI/ASC A14.1 defines Type II ladders as rated for 225 lbs; Type I (industrial) is rated for 250 lbs — the question refers to Type I industrial.
Question 3: During cable installation in an active data center, a technician must wear an ESD wrist strap when:
- Handling installed cables in cable trays
- Touching or handling sensitive network equipment components (Correct answer)
- Using power tools near racks
- Climbing ladder racks
Correct answer: Touching or handling sensitive network equipment components
ESD wrist straps are required when handling electronics to prevent electrostatic discharge from damaging sensitive components.
Question 4: A fire alarm sounds during cable installation work. A crew member suggests finishing the current pull before evacuating. The correct response is:
- Agree if it will only take two minutes
- Evacuate immediately following the site emergency plan (Correct answer)
- Silence the alarm and investigate before leaving
- Continue unless smoke is visible
Correct answer: Evacuate immediately following the site emergency plan
All fire alarms must be treated as real emergencies; immediate evacuation is required regardless of task status.
Question 5: Which OSHA regulation specifically addresses electrical safety standards for construction work, including data cable installation?
- 29 CFR 1910.147
- 29 CFR 1926.404 (Correct answer)
- 29 CFR 1910.303
- 29 CFR 1926.502
Correct answer: 29 CFR 1926.404
29 CFR 1926.404 covers electrical installation requirements for construction sites, including GFCI and assured equipment grounding conductor programs.
Question 6: What minimum illumination level (in foot-candles) does OSHA require for general construction work areas?
- 1 foot-candle
- 3 foot-candles (Correct answer)
- 5 foot-candles
- 10 foot-candles
Correct answer: 3 foot-candles
OSHA 1926.56 requires a minimum of 3 foot-candles of illumination for general construction work areas.
Question 7: An installer accidentally cuts a fiber optic cable and glass shards land on a work surface. What is the correct cleanup procedure?
- Wipe up shards with a dry paper towel using bare hands
- Use tape to pick up shards, then dispose in a puncture-resistant sharps container (Correct answer)
- Blow shards away with compressed air
- Sweep shards into a regular trash receptacle
Correct answer: Use tape to pick up shards, then dispose in a puncture-resistant sharps container
Fiber shards are invisible and razor-sharp; tape pickup followed by sharps disposal prevents skin penetration and eye injury.
