Machine Guarding Policy
Purpose and Application
This policy document is designed to ensure that CSB|OSB employees and students follow procedures which assure that equipment or machines are operated safely and meet state, federal, and industry machine guarding standards.
This applies to all employees and students who may work with, or adjacent to, equipment or machines that may pose a safety hazard.
“Machines” include, but are not limited to, fans, compressors, bench grinders, fuel pumps, dumpsters, trash compactors, and table saws. Any machine part, function, or process that may cause injury, must be safeguarded. When the operation of a machine or accidental contact with it can injure the operator or others in the vicinity, the hazards must be either controlled or eliminated.
A “machine hazard” occurs at the point of operation where the actual work is performed, and can be created by:
- components which transmit energy, such as pulleys, belts, chains, gears, couplings, or flywheels; or
- other parts which move while the machine is working, including reciprocating, rotating, and transverse parts.
Roles and Responsibility
The Offices of the Physical Plant and Facilities Management are responsible for ensuring guards on facility equipment and machines operated by physical plant personnel are kept in place and used as originally designed. In academic areas, the Lab/Shop Director or Department Head is responsible for ensuring guards on machines operated by personnel or students under their supervision are kept in place and used as originally designed.
The Environmental Health and Safety (EHS) prepares and updates the written Machine Guarding Program and responds to any employee or student machine guarding concern or question.
All affected employees and students should report any unguarded machine hazard to their supervisor immediately.
All employees should forward any student concerns or observations regarding the lack of machine guarding to their supervisor.
Each campus has a written machine guarding plan, which includes an inventory of guarded equipment and the procedure to be followed to minimize the risk of accidents
Hierarchy of Guarding
Machine guarding decisions should be made in the following order of preference:
- Design out or eliminate the hazard
- Physically “engineer out” the exposure to the hazard
- Guard the hazard · Require personal protective equipment
- Use warning devices, or make the danger “manifest”
- Use warning signs
- Use safe working practices and procedures
Inspections and Audits
Machines that require guarding will be inspected regularly by EHS. Based on the results of these inspections, maintenance or replacement of guards will be conducted as necessary. EHS will audit the program annually and recommend appropriate corrective actions.
Any person who works near, or adjacent to, any sort of machine will receive “affected employee” training during initial orientation and every two years thereafter. Affected employees receive machine guarding training specific to the hazards being controlled on the piece of equipment. The shop supervisor must train students using machines. Employees performing maintenance related activities will receive machine guarding training on an annual basis.
Physical Plant maintains records of the machine guarding inventory. EHS maintains records of machine guarding training and copies of the annual inspection checklists.
