All industrial and scientific tools require machine guards for the well-being of those who operate the machines. Different pieces of equipment have different degrees of danger when operating. Some of these can injure the softer parts of the body, such as the ears or eyes. Others are capable of crushing hands or arms.
There are 3 parts to every machine. The 1st of these parts is the point of operation. In this area, shaping, cutting, boring, as well as other such operations occur. The 2nd part of the machine is the transmission device. In this part are found such devices as belts, flywheels and pulleys. The 3rd part of the machine handles the operational controls. This part deals with such things as reciprocating, rotating, and feed mechanisms. Some moving parts are dangerous and should therefore not have direct contact with the operator. Machine guards can be used to keep the operator safe.
All machines can have guards made for them, such as safety barriers or fences, computerizes light curtains or plastic safety guards. High-temp valves also require guards. Custom guards may also be made. Operators, as well as those who are nearby, are protected by machine guards. These stop anything that the tool may produce, such as scraps that are sent flying, or showers of sparks.
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.
It is very important to remember the different people people who may be hurt by any given machine. Besides the operator and those nearby, others include a janitor who may bump in to a machine, or a mechanic who does regular maintenance work on 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.
