DCI Job Site Safety Practices 3

Question 1

Which class of fire extinguisher should be used if electrical equipment catches fire on a data cabling job site?

Accepted Answer

Class C

Answer

Class C extinguishers use non-conductive agents designed for fires involving energized electrical equipment.

Question 2

When should a data cabling technician wear safety glasses on a job site?

Accepted Answer

Whenever there is a risk of flying debris, dust, or chemical splash

Answer

Eye protection should be worn any time there is a potential risk of eye injury, not just when specific tasks are being performed.

Question 3

A technician is pulling cable through a conduit and feels significant resistance. What is the SAFEST course of action?

Accepted Answer

Use a cable lubricant and reassess; do not exceed the cable's minimum bend radius

Answer

Forcing cable beyond its bend radius can damage the cable and create injury risk; lubrication and reassessment is the correct approach.

Question 4

What is the purpose of a Job Hazard Analysis (JHA) performed before starting a cabling installation?

Accepted Answer

To identify potential hazards and establish safe procedures for each task

Answer

A JHA systematically identifies hazards associated with each job task and establishes safe work procedures to mitigate those risks.

Question 5

Which safety device on a power drill prevents it from continuing to spin after the chuck is fully tightened?

Accepted Answer

Torque clutch or clutch collar

Answer

The torque clutch disengages the drill's drive when a preset torque level is reached, preventing over-tightening and protecting the tool and user.
