Machine Guarding—An Overview
Overview Of Topic Machine operators who understand a machine’s hazards and how to control them will have a reduced risk of injury. Proper operation of the machine, including the machine guards, can improve productivity as well as safety. There are five general techniques for safeguarding machine operation, but all guards must be able to prevent contact, must be secured in place or be otherwise tamper-proof, must create no new hazards, should allow for lubrication with the guard still in place, and must not interfere with the machine operation.

Types of safeguarding
Several of the types of safeguarding would include:
• Guards — these can be fixed, interlocking, adjustable, or selfadjusting. They are a physical barrier to contact. • Devices — these can be presence sensing, pullback, restraint, operational controls, or gates. They limit or prevent access to the hazardous area.

• Location or distance — hazards are reduced by locating the machine so that its hazardous areas are not normally
accessible.
• Automated feeding and ejection methods — these eliminate some of the operator’s exposure to the hazards.
• Miscellaneous aids — shields, feeding-tools, holding devices, or awareness barriers also protect operators and people in the area.
The best machine operator knows what the machine does, how the operating controls affect the work, and when maintenance and repairs are needed. Operators who understand machine-specific operating instructions contribute to having a more efficient operation.

Instructions can also lead to less risk of injury because the instructions explain the machine’s operations and how to prevent, or at least recognize, a malfunction. A lack of knowledge and not noticing hazards often leads to injury.
