1. Tulane University - Office of Environmental Health & Safety (OEHS) Equipment Safety For Laboratory, Facility, and Office Employees Tulane University January, 2005

2. Tulane University - Office of Environmental Health & Safety (OEHS) Objectives To become aware of the need to inspect equipment. To identify provisions of proper machine safeguarding. To identify procedures for addressing potentially contaminated equipment. To review basic Lockout/Tagout for Facilities Services.

3. Tulane University - Office of Environmental Health & Safety (OEHS) Safe Use of Equipment Regularly inspect equipment, including office machines such as copiers & printers. Use equipment according to the manufacturer’s recommendations.

4. Tulane University - Office of Environmental Health & Safety (OEHS) Machine Guarding Guards are normally installed by manufacturer as standard equipment but not all commercial equipment meets OSHA requirements. If guards are not provided, they must be installed locally before placing machine in operation.

5. Tulane University - Office of Environmental Health & Safety (OEHS) Machine Guarding Ensure guard is in place to prevent contact with moving parts and hazardous motions. Areas needing guarding include belts, rollers, gears, saw blades, etc. (The belt and pulley are not guarded in the photo.)

6. Tulane University - Office of Environmental Health & Safety (OEHS) Machine Guarding Guards should: –Prevent contact with body parts, hair, clothing –Be securely in place –Create no new hazard or interference –Allow for safe lubrication and maintenance.

7. Tulane University - Office of Environmental Health & Safety (OEHS) Machine Guarding Guards must be firmly secured to the machine. –They should not be easily removed or subject to tampering Guards must be made of a durable material that can withstand conditions of normal use.

8. Tulane University - Office of Environmental Health & Safety (OEHS) Machine Guarding Guards must create no new hazards, such as a jagged edge or unfinished surface that could cause injury. – Guard edges should be rolled or bolted to eliminate sharp edges. Guards should not interfere with work. – A guard that hampers work or makes work uncomfortable may be overridden or disregarded.

9. Tulane University - Office of Environmental Health & Safety (OEHS) Machine Guarding Where possible, lubricate equipment without removing safeguards. –For example: a lubricating reservoir outside the guard with a line to the lubrication point reduces the need for the worker to remove the guard or work in the hazardous area.

10. Tulane University - Office of Environmental Health & Safety (OEHS) Potentially Contaminated Equipment Contaminants can be due to both usage or materials used in manufacturing equipment: –Biological agents, radioactive materials, toxic chemicals –Mercury switches, PCBs in transformers, Halon/Freon). Examples: –Refrigerators, microwave ovens –Fixed building equipment (plenums, ductwork & vacuum systems associated with lab hoods)

11. Tulane University - Office of Environmental Health & Safety (OEHS) Potentially Contaminated Equipment Prior to repair, cleaning, transport or disposal, equipment must be certified as safe with a written, attached tag. Certification may be the responsibility of the unit supervisor, OEHS, or maintenance depending upon the equipment used and necessary actions.

12. Tulane University - Office of Environmental Health & Safety (OEHS) Facilities Services – Lockout/Tagout Lockout/Tagout is used to prevent the release of hazardous energy, or unexpected equipment startup/energization, which can cause injury. The goal of Lockout/Tagout is the neutralization of all energy sources (mechanical, hydraulic, pneumatic, chemical, thermal) to obtain zero mechanical state.

13. Tulane University - Office of Environmental Health & Safety (OEHS) Facilities Services – Lockout/Tagout Always lock and/or use cautionary signage (tag) on equipment during maintenance or repair work. Example: Lockout & tag out electrical switches when working on electrical distribution panels, sub-panels, motor controls, fixed equipment, etc.

14. Tulane University - Office of Environmental Health & Safety (OEHS) Facilities Services – Lockout/Tagout Ensure power sources are disconnected & tagged out of service, then test to ensure power is off before beginning work. Wear proper PPE and use proper safety equipment. Upon completion of repair work, test the system before putting in service, restore controls to normal operations, remove tags, and replace panel covers.

15. Tulane University - Office of Environmental Health & Safety (OEHS) Facilities Services – Lockout/Tagout For additional information see: –OEHS Policies & Procedures Manual, Section 24, “Facilities Services” (The Manual is available on OEHS web page - www.som.tulane.edu/oehs.) www.som.tulane.edu/oehs –OSHA Standard for Control of Hazardous Energy (Lockout/Tagout) 29 CFR 1910.147

16. Tulane University - Office of Environmental Health & Safety (OEHS) Review Inspect equipment to ensure it is safe and proper safeguarding is in place. Safeguards prevent contact with moving parts and must not be removed when the equipment is in use. If not installed by the manufacturer, safeguards must be installed locally before placing equipment in operation.

17. Tulane University - Office of Environmental Health & Safety (OEHS) Review Potentially contaminated equipment must be certified as safe with a written tag prior to repair, cleaning, transporting or disposal. Lockout/Tagout is used to prevent equipment energization or unexpected movement.

18. Tulane University - Office of Environmental Health & Safety (OEHS) Review Lockout is neutralization of all energy sources to obtain zero mechanical state. Tagout is tagging of machinery receiving maintenance or repair work.
