For every industrial and scientific tool, a machine guard in necessary for the operator using it to be safe. All machines require these guards, though some machines are far more hazardous than others, and require special guards. These guards are needed to protect such delicate areas as the eyes and ears. In addition, some equipment is even able to crush arms or hands if the proper safety measure are not taken.
Machine guards make certain that the worker’s body won’t have direct contact with the machine. Every machine has three main areas. The first of these areas is the power transmission device, which may contain moving parts such as pulleys, belts and flywheels. The next area includes the operational controls, and may use rotating, reciprocating and feed mechanisms. The third area is the point of operation. It includes boring, cutting, shaping, or something similar.
Machine guards are used to protect not only the operator, but also others nearby, from anything the use of the tool causes, such as sparks or pieces of metal that are flung out. Machine guarding can be made for all types of machines, and can be customized. Examples of these guards are safety fences or barriers, plastic safety guards, and computerized light curtains. Guards will also be needed for exposed wires and high-temp valves.
A great deal of machine guards are made to be used permanently. This may be the case even if the guard is not directly attached to the instrument it was made for. Such a guard would be a high barrier around certain work spaces. Even small tools require guards; the size the tool does not make a difference to the need for a guard. An example of a small tool that would need one is a small welding tool, which is still able to create sparks.
When installing the guards, it is critical to remember all the people who may come into contact with the machine. Such People are repairmen who do routine maintenance on the machine, and janitors who may accidentally brush past or bump into the machine.
For some machine guards, self-installation can be done, such as with safety switches or special lighting. For others, however, it is best to let professionals do the installation. At the least, professionals should be consulted before any installation is done.
Many places do not use machine guards, even though the need for them is clear. It is the responsibility of the owner of the tool or the employer to make sure that each piece of equipment has a machine guard. It is important to have these as soon as industrial and scientific tools are purchased. By doing so, liability is minimized. In addition, it makes sure that every machine will be properly checked, and a machine guard properly installed.
