4. Interlocked guards automatically shut off or disengage a machine through a tripping mechanism or power when the guard is opened or removed. Guards and safety devices should be made of durable materials that will withstand normal use. Because practical solutions to safeguarding moving machine parts are as numerous as the people working on them.

Machines should be installed in accordance with National Fire Protection Association and National Electrical Code requirements. Guards designed and installed by the machine producer are desirable because they conform to the design and function of the machine, and they can be designed to strengthen the machine or to serve some additional functional purpose.
This is a threat where stock is inserted, held and withdrawn, as with equipment such as power presses. The danger is where stock is inserted, held and withdrawn, as with hydraulically or pneumatically powered shears. General requirements for machine guards. General requirement 1910.212(a)(1) states that one or more methods of machine guarding must be used to protect operators and other employees from hazards, including those created by point of operation, in-running nip points, rotating parts, flying chips and sparks. Potential hazards include the points of contact between a power transmission belt and its pulley, a chain and its sprocket, or a rack and pinion. Supervisors should frequently inspect equipment to ensure the guards are in good working order and functioning properly.
Sometimes, a skilled user may need to alter and improve the equipment or design and build new guards. This may require a full walkthrough of your facility or facilities. 5. 8. OSHA’s Denver Regional Office reported a fatality caused by the installation of transparent replacement guarding material having a lower impact resistance than the manufacturer's original guard for the machine. Radio frequency or capacitance devices use a radio beam that is part of the machine circuit. The basic types of hazardous mechanical motions and actions are: A rotating motion can be dangerous. Rotating (including in-running nip points). Locating oil reservoirs outside the guard, with a line leading to the lubrication point, will reduce the need for the operator or maintenance worker to enter the hazardous area. Return to Productivity. Is there evidence that any safeguards have been tampered with or removed? They also might be the only choice for mechanical power transmission apparatuses in older plants.
In other cases, machines generate sparks or flying chips that can injure workers.
In addition to guards at the point of operation, guards should protect against other moving parts such as the following: Additionally, starting and stopping controls should be within easy reach of the operator.

Perhaps safeguards have been removed because they got in the way or the nature of the work changed.
Why? a description and identification of the hazards associated with particular machines, the safeguards themselves, how they provide protection, and the hazards for which they are intended, how and under what circumstances safeguards can be removed, and by whom (in most cases, repair or maintenance personnel only), when a lockout/tagout program is required, what to do (e.g. Are there guards in place for ALL hazardous parts of machines? Potential Hazards Associated with the Use of Replacement Materials for Machine Guarding (PDF). These guards are preferable because they’re simple and permanent.
