DCI Job Site Safety Practices 5 — Questions and Answers
Question 1: When working in a customer's occupied office building, which practice BEST demonstrates professional job site safety etiquette?
- Propping open all fire doors to make cable pulling easier
- Notifying building occupants of work areas and maintaining clear emergency exits (Correct answer)
- Removing ceiling tiles in all areas at the start of the day for efficiency
- Running cables across hallway floors temporarily to save time
Correct answer: Notifying building occupants of work areas and maintaining clear emergency exits
Professional cabling technicians keep occupants informed, maintain emergency exit access, and minimize disruption to the workplace.
Question 2: Which type of respirator is appropriate when removing old asbestos-containing floor tiles encountered during a below-floor cabling installation?
- A standard dust mask (N95)
- A half-face respirator with P100 particulate filters
- A full-face supplied-air respirator used only by certified asbestos abatement professionals (Correct answer)
- No respirator is needed if the tiles are not broken
Correct answer: A full-face supplied-air respirator used only by certified asbestos abatement professionals
Asbestos abatement requires certified professionals with full-face supplied-air respirators; cabling installers should stop work and call the appropriate contractor.
Question 3: A technician is using a cable fish tape in a wall cavity. What electrical hazard must be assessed before inserting the fish tape?
- Whether the wall paint contains lead
- Whether energized conductors are present in the wall cavity (Correct answer)
- Whether the wall cavity is insulated with fiberglass
- Whether the fish tape is the correct length for the run
Correct answer: Whether energized conductors are present in the wall cavity
Metal fish tape contacting an energized conductor in a wall cavity can cause electric shock or electrocution.
Question 4: What is the OSHA-required maximum height for storing materials on shelves or racks in a job site storage area?
- 6 feet from the floor
- Within 18 inches of the ceiling sprinkler heads (Correct answer)
- As high as the rack manufacturer allows with no additional limit
- No higher than the reach of the shortest worker on site
Correct answer: Within 18 inches of the ceiling sprinkler heads
OSHA and NFPA require at least 18 inches of clearance below fire sprinkler heads so water can spray effectively in case of a fire.
Question 5: A DCI technician is working on a rooftop to install an antenna cable feedthrough. Which environmental hazard requires specific PPE not normally needed for indoor work?
- Noise from HVAC equipment on the roof
- UV radiation and solar heat requiring sun protection (Correct answer)
- Bird droppings containing harmful pathogens
- Vibration from rooftop mechanical equipment
Correct answer: UV radiation and solar heat requiring sun protection
Prolonged rooftop work exposes technicians to UV radiation and high heat requiring sunscreen, UV-protective clothing, and hydration measures.
Question 6: When pulling cable with a mechanical cable puller through a long conduit run, which safety practice prevents injury to the hands?
- Wearing thin latex gloves for grip
- Never placing hands near the rope, capstan, or cable entry point while the machine is running (Correct answer)
- Keeping one hand on the cable at all times to feel for snags
- Reducing the pulling speed to the lowest setting
Correct answer: Never placing hands near the rope, capstan, or cable entry point while the machine is running
Hands must be kept clear of the capstan, rope, and cable entry point while a mechanical puller is operating to avoid crush or entanglement injuries.
Question 7: Which document should a cabling technician review before beginning work in any facility to understand site-specific emergency evacuation procedures?
- The cable manufacturer's installation guide
- The site-specific Emergency Action Plan (EAP) or facility safety orientation materials (Correct answer)
- The local building permit for the cabling project
- The National Electrical Code (NEC) Article 800
Correct answer: The site-specific Emergency Action Plan (EAP) or facility safety orientation materials
The Emergency Action Plan outlines evacuation routes, assembly points, and emergency contacts specific to that facility.
