Proprietary and Confidential MACHINE SAFEGUARDING Supervisor Leadership Training Series "Our loss control service is advisory only. We assume no responsibility for management or control of customer safety activities nor for implementation of recommended corrective measures. This presentation is based on information supplied by the customer and/or observations of conditions and practices at the time of the consultation. We have not tried to identify all hazards. We do not warrant that requirements of any federal, state, or local law, regulation or ordinance have or have not been met.”

2 Proprietary and Confidential Do ’ s Actively participate by contributing –Ask questions –Share experiences –Request explanations Be supportive of your co-workers Apply what you learn to your job Pass on the information

3 Proprietary and Confidential Objectives Discuss how to: Identify & prioritize risk Maintain/improve production without creating hazards Identify & correct hazards Reduce potential liability

4 Proprietary and Confidential Basics of Machine Safeguarding Assess existing and residual risk –Use R3, ANSI B11 TR3 or similar method Safeguard based on: –Frequency (F) of exposure (anticipated & real) –Likelihood (L) & Severity (S) of potential injury Evaluate machines and equipment –Safeguard any part, function or process which may cause injury/illness to operator(s) or others in the vicinity Use engineering, training/educational, and motivation controls Inspect safeguards routinely –Properly installed, used & functional

5 Proprietary and Confidential Machine Guarding General Requirements – One or more methods of machine guarding shall be provided to protect the operator and other employees in the machine area from hazards such as those created by: –Point of operation –Ingoing nip points –Rotating parts –Flying chips –Sparks Guards shall be affixed to the machine where possible and secured elsewhere if for any reason attachment to the machine is not possible. The guard shall be such that it does not offer an accident hazard in itself.
