Main hazards

• Cuts or punctures from the tip slipping off the screw head.
• Damage to the screw or work surface from using an unsuitable tip type or size.
• Electric shock when working near live circuits with non-insulated tools.
• Ejection of particles, rust or swarf towards the eyes and face during driving or removing screws.
• Injuries from applying excessive force or using the tool as a lever, chisel or punch.
• Fatigue and discomfort in the wrist and forearm due to awkward postures or prolonged use.

Safe use

• Always choose the correct type and size of screwdriver or bit; check it fully engages in the screw head recess before turning.
• Keep the handle dry and free of grease; hold firmly and align the tool with the axis of the screw.
• Apply controlled pressure and turn smoothly to prevent slippage (cam-out).
• Wear eye protection whenever there is a risk of particles or when working with rusty screws.
• If working near electricity, isolate the supply whenever possible and use insulated screwdrivers designed for that environment; avoid touching exposed metal parts.
• Do not strike the screwdriver or use spanners, tubes or other levers to increase torque, unless clearly specified by the manufacturer.
• Ensure the tip is not rounded or damaged; replace it if it does not grip properly. On models with interchangeable bits, ensure it is correctly locked in place.
• Keep your other hand and body out of the tool’s potential slip path to prevent injury if it slips.
• With hard or seized screws, prepare the area (cleaning, penetrating oil) or use dedicated tools to loosen them before forcing the screwdriver.
• When working at height, tether the tool to prevent accidental drops.

Storage and maintenance

• Clean the tip and handle after use to remove dirt, oils and filings.
• Store in a dry, ventilated place; protect from moisture to minimise corrosion.
• Keep away from heat sources and prolonged direct sunlight that could degrade the handle.
• Organise screwdrivers and bits in cases or racks; use tip protectors when available.
• Inspect periodically for: cracks in the handle, a bent shaft, a chipped or rounded tip and, on insulated models, possible damage to the coating. Remove defective tools from service.
• If the tip is magnetised, remove any adhering filings and keep it away from magnetic media and sensitive sensors when not in use.

Restrictions on use

• Do not use the screwdriver as a lever, chisel, punch, scraper, or to open tins or lids.
• Do not work on live circuits unless the tool is suitable for that purpose and safety measures are in place; preferably, isolate the power.
• Do not modify, heat or sharpen the tip; do not remove handle coatings or insulation.
• Do not attach makeshift extensions (tubes, spanners) to increase torque.
• Do not use screwdrivers with a loose handle, worn tip or damaged shaft.
• Do not use magnetised tips near magnetic media or sensitive components if their operation could be affected.
• Keep out of reach of children; if used by children, ensure adult supervision.
