Relocate the system for maintenance

The substances that accumulate in the exhaust pipe, elbow and check valve can be dangerous. Do
not allow these substances to come into contact with skin or eyes. Do not inhale vapours from
these substances. Fit blanking caps to the inlet and outlet flanges when moving the exhaust pipe,
elbow or check valve around the workplace.
The majority of synthetic oils/grease can cause inflammation of the skin (dermatitis). Safety
precautions must be taken to prevent prolonged skin contact with these substances. Use of
suitable protective gloves and clothing along with a respirator is recommended if contact with the
substance is anticipated. System process gases and residue can be highly toxic. Take all necessary
precautions when handling components that have, or could have, come into contact with them,
including O-rings, lubricants and all exhaust accessories.
Use suitable lifting equipment to move the system. Failure to do so can cause injury to people and
damage to the equipment.
