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 kinds of machines can have machine guards made for them. These can be standard or custom-built. When pieces of metal are slung around or when when sparks fly, machine guards protect both the operator as well as people who are nearby. Some examples of guards are computerized light curtains, plastic safety guards, fences, and other barriers. High-temp valves, as well as exposed wires, also use these guards.
All machines require machine guards, regardless of their sizes. An example of a small piece of equipment that will still need it is a small welding tool: using it still produces a lot of sparks. A great deal of these guards are permanent, even though many of them are not directly attached to the machines they are used for, such as barriers that enclose operational areas.
It is very important to bear in mind that several people may come into contact with a given piece. Examples of this are janitors, who may accidentally knock in to a machine, or mechanics, who regularly do maintenance work on specific pieces of equipment.
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.
Despite the needs for having them, not all places use machine guards for their equipment. When purchasing other industrial and scientific tools, it is the responsibility of the employer or owner to ensure that these one are installed for each machine. This not only minimizes liability, but ensures that each machine will be seen to properl
