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.
All machines have three main sections of function. The first is the power transmission device. This section often uses moving parts such as flywheels, belts and pulleys. The second section is the point of operation. This area sees to shaping, boring, cutting or something similar. Finally, the third section contains the operational controls. This section includes feed mechanisms, reciprocating and rotating. By using a machine guard, it makes certain that the operator’s body will not have direct contact with any of the dangerous moving parts.
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 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.
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
