“Safe Use of Cable Crimpers”

Key Hazards

Pinched fingers between crimping jaws and connectors
Cuts or punctures from sharp cable strands or wire ends
Electric shock from working on energized conductors
Tool failure from damaged dies, jaws, handles, or hydraulic parts
Battery or charger hazards from powered crimpers
Poor crimps causing overheating, arcing, or connection failure

2–3 Minute Talk Script

Cable crimpers are used to make electrical and communication connections. A crimp that is unsafe or a tool used incorrectly can create both immediate hand injuries and future electrical hazards.

Workers should inspect the crimper before use. Jaws, dies, handles, hydraulic components, batteries, chargers, labels, and alignment should be checked.

Conductors should be de-energized unless the work is specifically authorized and controlled by qualified workers using the required procedure.

Hands and fingers should stay clear of the crimping jaws. Crimpers can create high force and close quickly.

Sharp cable strands, cut wire ends, and connector edges can puncture or cut skin. Gloves and careful handling may be needed.

The correct die, connector, and cable size should be used. A mismatched crimp can fail, overheat, loosen, or create electrical resistance.

Powered, hydraulic, or battery crimpers should be used according to the manufacturer’s instructions. Damaged batteries, leaking hydraulic components, or abnormal tool movement should be reported.

Safe cable crimper use depends on energy control, tool inspection, correct component selection, hand placement, and verifying that each crimp is complete and secure.

Safety Reminders

Inspect crimpers, dies, jaws, and handles before use.
De-energize conductors before work when required.
Keep fingers clear of crimping jaws.
Use the correct die, connector, and cable size.
Watch for sharp wire strands and cut ends.
Report damaged hydraulic, battery, or powered crimpers.
Verify crimps before placing equipment back in service.

Ask the Crew

Is the conductor de-energized or properly controlled?
Is the crimper in safe condition?
Are the correct dies, connectors, and cable sizes being used?
Where are the worker’s fingers during the crimp?
Could a poor crimp create heat, arcing, or failure later?
