Safety Related Notes
Before working on equipment of any kind, perform lockout-tagout procedures per the rules of your plant. Determine the sources of energy on the machine – electrical, pneumatic and hydraulic – and release or vent sources of stored energy – electrical capacitors, air receivers, and hydraulic accumulators. Shut off sources of power – electrical, pneumatic and hydraulic. Be alert to the following:
1. Safely block mechanical sources of energy such as loaded springs and loaded machine members, or safely position the machine members so they are unloaded and springs are not under tension.
2. Beware of hot hydraulic fluid and hot surfaces which can cause burns.
3. Never “crack a hydraulic or pneumatic fitting” to check for the presence of stored energy. This may lead to a fluid injection injury. Injection injuries from fluids, are extremely serious and must be treated immediately by medical personnel familiar with this type of injury. Loss of body parts or death may result from improperly treated fluid injection injuries!
4. Review the schematics and think before proceeding to work on the machine.
5. Never assume that pressure has been eliminated.
