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.
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.
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.
Professionals should always be consulted when any guards are going to be installed. In many situations, the professional will also be the one installing the guard. In some others, however, such as special lighting or safety switches, others may be able to do the installation themselves.
The owner or employer needs to make sure that each industrial and scientific tool is installed with a machine guard. This will decrease liability as well as maker sure that every machine is properly outfitted. Even though the need for these guards is clear, not all people use them when they should.
