The common methods of safety are as follows:
Few of the above methods of safety are discussed as under.
Whenever the new tools, devices, equipments and machine are designed, they should be ensured that all their dangerous parts are either enclosed in suitable housings or provided with suitably designed safety guards in order to eliminate any chances of danger that could occur due to exposure of the dangerous parts. A common example involve belt drive and motor in a in drilling machine, lathe, milling or in other machines are enclosed, the back gears and tumbler gears in a lathe are either enclosed or provided with cast iron guards or covers. All control levers and handles of machines should be carefully located to ensure adequate safety in their operation.
The main principle involved in the method for safety by position is to design the machine in such a way that the dangerous parts are so located or placed that they are always beyond reach of the operator. It is therefore always advisable that all the dangerous parts of the machine should invariably be guarded or enclosed in the body or housing of the machines asar the design conditions permit. If it is not possible suitable external fencings must be incorporated suitably.
Such fixed guards either form an integral part of the machine or are so tightly secured to them that they are not easily removable. In all cases, fixed guards are developed to have a robust and rigid construction and they should be so placed that any access to the dangerous parts of the machine is totally prevented from all directions particularly in the running condition of the machines. In some cases the fixed guards are provided at a distance from the danger point. Such a provision will carry a remote feeding arrangement and, therefore, the operator will not be required to go near the dangerous points.
An interlocking guard may be mechanical, electrical, pneumatic or some sort of a combination of these.Such guards cannot be removed and the dangerous parts are not exposed until and unless the machine is totally stopped. Such arrangements prevent the starting and operation of the machine in case the interlocking device fails and remain closed in position until the dangerous part is completely at rest. Scotch interlocking and control interlocking designs of these guards are common used to protect accidents. The former interlocking consists of a solid metal piece, called scotch connected to it which is so located that it remains between two moving parts of the machine.
Automatic guard and machine operation is so linked that the part will automatically bring the guard in protecting position before the operation of the machine starts. The design of this guard is of such a kind that it automatically forces the operator to move away from the dangerous area of work before the operation starts. Such arrangement of such guard does not permit the operator access to this area again until and unless the machine stops. The use of such guard is largely favored for heavy and slow acting machines like heavy power presses.
Distance guard helps to fence the dangerous components of machine such as bars or rails and position them at a suitable distance from the machine such that even operator by chance, extends his hands over it, his fingers, clothes or any of the body does not reach within the area of dangerous parts. For additional safety, some sort of tripping device should always be incorporated to stop the machine rapidly in case of an accident.
Trip guard in machine is comprised with tripping device which enables quick stopping or reversal of the motion of machine as soon as the operator approaches within the reach of dangerous parts. Tripping device and the trip guard works in close conjunction with each other during problematic situations.

Read moreThe following general types of safety are considered in the workshop.
1. Safety of self.
2. Safety of job.
3. Safety of machines tools.
Developing a solid safety plan is vital in workplaces, and recreational areas. It starts with a thorough risk assessment to identify potential hazards and assess their possible impact. Equally important is being well-prepared for emergencies, involving the creation of clear plans for different scenarios.
