The hazards posed by an unguarded machine are obvious: in the worst of all cases the machine can do to your body parts what it's doing to the materials it's designed to cut, shape, or form.
One of the major goals of OSHA is to guard all machinery and equipment to eliminate hazards created by points of operation, ingoing nip points, rotating points, and flying chips and sparks.
The words "shall be guarded" apply to most machines and equipment the University uses. Some machines require specific guarding methods and all machines are regulated by the general requirements.
To reduce accidents to workers through the use of machine guards and other safe guards.
All personnel using machinery at the University will adhere to the OSHA regulation 1910.111-.222.
There shall be one or more methods of machine guarding provided to protect the operator and other employees in the machine area from hazards. Examples of guarding methods are:
Interlocked guard - when opened or removed disengage the machine's power source. It cannot be restarted until the guard is replaced.
Adjustable guard - provide a barrier that can be adjusted to many different operations, such as varying sizes of stock.
Self-adjusting guard - barriers that move or self-adjust, according to the size or position of the workplace. The guard returns to its resting position when no material is passing through.
Point of operation is the area on a machine where work is actually performed upon the material being processed. The point of operation of machines whose operation exposes an employee to injury shall be guarded. The guarding device shall conform with any appropriate standards. If no specific standard exists then the design and construction of the guard will prevent the operator from having any part of his body in the danger zone during the operating cycle
The following are some examples of machines requiring point of operation guarding:
When the periphery of the blades of a fan Is less than seven feet above the floor or working level, the blades shall be guarded. The guard shall have openings not larger than one-half inch.
Machines designed for a fixed location shall be securely anchored to prevent walking or moving.
