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.
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.
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.
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 spoken to before any machine guards are installed for equipment. Usually, the professionals do the installation as well. In some cases, though, it is possible for others, such as the owners, to do the installation. Examples of such situations are when the guards only require special lighting or safety switches.
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.
