BS4163 Main points: HAND TOOLS Hazards Employees and students should be aware of the following hazards: - Sharp tools - Falling tools - Tools breaking or coming apart in use Slipping of tools, which can occur when pressure is applied to them

Suitable materials and processes: A chisel is a tool with a characteristically shaped cutting edge of blade on its end, for carving or cutting a hard material such as wood, stone, or metal. The handle and blade of some types of chisel are made of metal or wood with a sharp edge in it. In use, the chisel is forced into the material to cut the material. The driving force may be manually applied or applied using a mallet or hammer.

Risk Control Measures Hand tools should be stored at suitable height for access. Hand tools should not be left projecting from a bench The faces of hammer heads and hammer shafts should be frequently inspected. Damaged heads and shafts should be discarded. It is essential the correct handle is securely fixed on the tool. Wedges in hammer shafts should be kept tight ‘Mushrooming’ on the struck ends of metal working chisels should be removed regularly Edged tools should be kept sharp and in good condition Sawing boards (bench hooks) should be maintained in good condition Instruction should be given on correct use of hand tools. Sharp or pointed tools should be handled with care (with cutting edges protected or pointing downwards) Tools should not be carried in pockets or under belts The correct size spanner should be used to fit nuts and bolts. Packing pieces should not be used.

A gouge, one type of chisel, is used, particularly in woodworking, woodturning and sculpture, to carve small pieces from the material. Gouges are most often used in creating concave surfaces. A gouge typically has a 'U'-shaped crosssection.

CLEAPSS Main Points: HAZARDS Cuts - Chisels and gouges are used for wood carving and hand cutting of mortises, dovetails, etc. Incorrect use or careless handling of sharp tools can cause cuts. Impact Injury - The use of a hammer or mallet may give rise to an impact injury if used incorrectly. The work may also fly off the bench if it is not held securely. RISK ASSESSMENT

Common Problems: Novices are quite likely to hit their fingers with a hammer while attempting to use a cold chisel Using the wrong type of tool for the job When using a chisel, the work is not held against a suitable flat surface with a G clamp or bench holdfast or vice.
