Safe Working Practices Regulations, Sections 5,6,7.
Hand Tools
Always use the right tool for the job and make sure that it is in good condition. Handles of hammers, screwdrivers and chisels should be secure. Wooden handles should be smooth and free of splinters, and the edges of chisels and punches should be clean and true.
Store tools in a suitable tool rack, box or carrier, with cutting edges protected.
Portable Power Tools
Portable power tools can be dangerous unless properly maintained, handled and used. Always inspect the tool and its cable or power supply lead before use and leave repairs to a competent person. Where a safety guard is needed for a particular operation, make sure that it is securely fixed before you begin the work.
Always disconnect the tool from its power supply when not in use or when you change accessories or guards. Never use electrical tools in wet conditions.
Keep electrical leads and pneumatic hoses clear of sharp edges and hot surfaces, or anything else that might damage them. If leads and hoses have to pass through doorways, secure the door open and, where they trail across decks or passageways, suspend them high enough for people to pass underneath. Handle paint sprayers like power tools; don't try to clean them or change nozzles with the power on. Make sure the nozzle is pointing the right way before starting to spray.
