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.
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.
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 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.
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
