All machines need some greasing from time to time. The lubrication of bearings, wear points, and moving parts are an essential factor in proper machine maintenance. But, there are serious risks if safety procedures are not followed.
The most common hazard is getting caught in moving parts while oiling the machines. This problem is due to a failure to follow lockout/tagout procedures. Every time maintenance needs to be performed, the machine should be locked out and all power turned off. All moving parts should be at rest before any lubrication is done.
Operators should be told to call maintenance people for oiling and not to attempt to do it themselves. Maintenance personnel should be trained and authorized in the correct lockout/tagout procedure. It may be best to arrange to have most lubrication done during off-hours.
The people responsible for oiling the equipment should dress safely for the job. They should not wear long, dangling sleeves or ties or other loose clothing that might be caught in moving parts. If anyone has long hair, it should be tied back.
Make sure your personnel are using the right grade of oil or grease to reduce the frequency of lubrication to a minimum. There should be a regular lubrication schedule so that no one forgets to oil that last bearing. Unlubricated parts can lead to an accident if they break down at the wrong time.
Use safe equipment for getting at hard to reach points. Long spout oilcans, grease gun extensions, extended feed pipes, etc. can help in filling oil cups from a safe and convenient position. If your workers need to remove guards, they should replace them when they are done.
Sloppy lubrication can create fire hazards and potential slips and falls. Prevent oil spills by using catch pans and clean up any slippery areas immediately.
