Safety Information

Visual Inspection: Before each use, carefully examine VDE screwdrivers for damage to the insulation. Any cuts, cracks, or exposure of the inner warning layer means the tool must be withdrawn from service immediately. Never use damaged VDE tools on live equipment.

Voltage Verification: Always use appropriate voltage detection equipment to confirm circuits are live before relying on VDE protection. The insulation provides protection against accidental contact but does not replace proper electrical safety procedures.

Compliance with Regulations: Follow HSE guidance and BS 7671 wiring regulations when working with electrical installations. VDE tools should only be used by competent persons with appropriate training in electrical safety and live working procedures.

Storage and Maintenance: Store VDE screwdrivers in clean, dry conditions away from chemicals, solvents, and extreme temperatures that might degrade the insulation. Clean with mild detergent and water; avoid aggressive cleaning agents that could compromise the protective layers.

Replacement Schedule: Establish a regular inspection and replacement programme for VDE tools used professionally. Heavy use, harsh environments, or any visible deterioration are indicators that tools should be replaced to maintain safety standards.

Training Requirements: Ensure all users understand the limitations of VDE protection and have received adequate instruction in electrical safety principles, isolation procedures, and emergency response protocols.
