DANGER

1 Mechanical hazards

1.2 Electrical hazards

1 Do not operate the pump with any parts of the enclosures removed or

damaged as there may be a risk of an electric shock.

1.3 Thermal hazards

1 Risk of burns. Do not touch the pump inlet or exhaust ports whilst the pump

is running since the temperatures of these parts could be high enough to

cause harm. Elevated temperatures could remain after the pump has

stopped.

1.4 Hazards caused by materials and substances

1 If within the system toxic substances or gases are being used, then the

operator will be responsible for ensuring that the corresponding safety

precautions are introduced!

2 If the pump has previously pumped hazardous gases take the appro-

priate safety measures before opening the intake or exhaust ports. Use

gloves, a breathing mask or protective clothing to avoid skin con- tact with

toxic or highly corrosive substances. Work under a fume hood.

3 Contaminated parts can be detrimental to health and environment.

Before beginning with any work, first find out whether any parts are

contami-

nated. Adhere to the relevant regulations and take the neces- sary

precautions when handling contaminated parts.
