cal power cord. Wait two minutes after isolating the

discharge.

cess chemicals that have been pumped during opera-

tion. Ensure that the pump is decontaminated before

maintenance.

Avoid the release of pollutants.

Take adequate precautions to protect people from the

effects of dangerous substances that may have con-

taminated the pump and may be released upon dis-

assembly. Ensure that the maintenance technician is

products processed by the pumping system.

Use appropriate protective clothing, safety goggles

and protective gloves.
