Safety Tips for Using Cutting Tools

Cutting tools may look simple, but when dealing with electricity, sharp blades, and heavy-duty cables, safety should always come first. Whether you’re a professional electrician, an industrial worker, or a DIY enthusiast, following these safety guidelines ensures both personal safety and the longevity of your equipment.

1. Always de-energize before cutting

Never attempt to cut a live wire or energized cable. Even low-voltage wires can cause serious electric shocks. Always turn off the power at the source and double-check with a voltage tester before making any cuts.

2. Use insulated tools for electrical work

When working on electrical installations, always use tools with insulated handles rated for electrical safety (often up to 1,000V). This protects you in case of accidental contact with live circuits.

3. Wear proper personal protective equipment (PPE)

• Gloves: Insulated gloves protect against electric shock and provide grip when handling slippery cables.
• Safety glasses: Prevents metal fragments, insulation shreds, or sparks from entering your eyes.
• Protective clothing: Avoids burns or cuts from sharp wire ends.

4. Choose the right tool for the cable size

Using small cutters on thick power cables can cause slipping, crushing, or even snapping of the blades. Always check the tool’s capacity rating before use.

5. Keep tools sharp and well-maintained

Blunt cutters require more force, increasing the risk of accidents or hand injuries. Regularly sharpen, clean, and lubricate your tools to ensure smooth operation.

6. Secure the cable before cutting

Hold the wire or cable firmly and, if possible, place it on a stable surface before cutting. Unstable cables may cause inaccurate cuts or injuries.
