Which class of fire extinguisher should be used if electrical equipment catches fire on a data cabling job site?
Answer: Class C
Class C extinguishers use non-conductive agents designed for fires involving energized electrical equipment.
When should a data cabling technician wear safety glasses on a job site?
Answer: Whenever there is a risk of flying debris, dust, or chemical splash
Eye protection should be worn any time there is a potential risk of eye injury, not just when specific tasks are being performed.
A technician is pulling cable through a conduit and feels significant resistance. What is the SAFEST course of action?
Answer: Use a cable lubricant and reassess; do not exceed the cable's minimum bend radius
Forcing cable beyond its bend radius can damage the cable and create injury risk; lubrication and reassessment is the correct approach.
What is the purpose of a Job Hazard Analysis (JHA) performed before starting a cabling installation?
Answer: To identify potential hazards and establish safe procedures for each task
A JHA systematically identifies hazards associated with each job task and establishes safe work procedures to mitigate those risks.
Which safety device on a power drill prevents it from continuing to spin after the chuck is fully tightened?
Answer: Torque clutch or clutch collar
The torque clutch disengages the drill's drive when a preset torque level is reached, preventing over-tightening and protecting the tool and user.
An installer is working alone in a remote equipment room. Which safety practice is MOST important in this scenario?
Answer: Inform a supervisor or coworker of location and check-in schedule
Working alone increases risk because there is no one to assist in an emergency; a buddy system or check-in schedule is essential.
What is the minimum safe working distance from overhead power lines for cabling work that does not require special equipment or permits?
Answer: 10 feet
OSHA requires a minimum 10-foot clearance from energized overhead power lines up to 50kV for unqualified workers.
