USE of HAND TOOLS
Hand tools are non-motorised, including axes, keys, screwdrivers, hammers, etc. The greatest hazards posed by hand tools result from misuse and poor maintenance. Training and training programs for employees must provide detailed training on the proper use of the hand. Tools for the specific area of operations in which they will work in. Attention will be given the selection of tools, the use of the tool and the appropriate personal protective equipment to be used when using the specific tool as shown in the following sections:Metal-Cutting Hand Tools:
Chisels
The factors determining the selection of cold scissors are the materials to be cut, the size and the shape the tool, and the depth of the cut to be done. The chisel must be heavy enough for him will not shear or come out when struck. A chisel no larger than the material should be chosen so that the blade is used rather than the tip or corner. In addition, a hammer heavy enough to do the job should be used.
Employees are required to wear safety glasses when using a chisel and should set up a screen or screen to prevent other employees from injuring chips. If a shield does not protect all exposed employees, all employees in the work area must wear goggles with side protection.
Tap and Die Work
The tap work and die should be firmly mounted in a vice. Only a T-handle wrench or an adjustable faucet a key should be used. When the threads are cut by hand, the hands and arms should be kept away from the sharp threads that pass through the die, and the metal cuttings should be cleaned with a brush.
Hack Saws
Files
Selecting the right type of file for the job will prevent injury and lengthen the life of the file. The file should never be cleaned by hitting it against a vise or other metal object because of the possibility that file chips become flying debris. A file cleaning card or brush must be used. A file should not be hammered or used as a lever. Using a file in this way often causes the file to burst or break, causing injury to the user. A file should not be made in a centre punch, chisel or any other type of tool because the hardened steel can fracture in service. A file should never be used without a smooth handle without cracks; if the file was to be hung. At the top, the silk can perforate the palm of the hand, the wrist or another part of the body. Under certain conditions, a raised deported handle may be useful to give more clearance for the hands. Files should not be used on a high-speed turning stock (more than three turns per file shot) because the end of the file can hit the chuck, the dog, or the face plate and throw the file (or metal chip) to the operator strong enough to inflict serious injury.
Tin/Sheet Metal Snips
The tin shears should be heavy enough to cut the material so easily that the worker only needs one hand on the shears and can use the other to hold the material. The material must be well supported before the last cut so that the cut edges do not rest on the hands. The jaws of the shears must be tight and well lubricated. Employees are required to wear safety glasses when cutting corners or shards of metal because small particles often fly with considerable force. Employees are also required to wear gloves during cuts.
Cutters
Strawberries used on the wire, rear or bolts must have sufficient capacity for the stock; otherwise, the jaws can be hung or spread out. The chips can fly from the sharp edge and injure the user. Lubricate the knives frequently. To prevent the cutting edges from being chipped or chipped, knives must not be used as pulling or levering devices. Cutting jaws shall have the hardness specified by the manufacturer for the particular type of material to be cut.
