“Safe Use of Heat Shrink Tubing”
Key Hazards
- Burns from heat guns
- Overheating wires
- Inadequate insulation from uneven shrinking
2–3 Minute Talk Script
Safe use of heat shrink tubing is important for electricians, technicians, and maintenance staff. Heat shrink provides insulation but requires controlled heating.
Workers should heat tubing evenly by moving the heat source in small motions. Holding the heat in one spot can scorch wires.
Different tubing sizes shrink differently. Workers should choose tubing that fits snugly without requiring excessive heat.
Letting tubing cool before handling prevent burns and ensures proper adhesion.
Safety Reminders
- Heat evenly.
- Use correct tubing size.
- Avoid overheating wires.
- Allow cooling before touching.
Ask the Crew
- Are we using heat guns or torches today?
- Do we have tubing sizes that fit the job?
