The equipment is subject to pressure!
▶ Risk of severe injury or death
Depressurize the plant or plant component.
●
Completely drain the plant or plant component.
●
Corrosive chemicals!
▶ Risk of caustic burns
Wear appropriate protective gear.
●
Completely drain the plant.
●
Hot plant components!
▶ Risk of burns
Only work on plant that has cooled
●
down.
Use as step!
▶ Damage to the product
▶ Risk of slipping-off
Choose the installation location so that the product can-
●
not be used as a foothold.
Do not use the product as a step or a foothold.
●
Leakage!
▶ Emission of dangerous materials
Provide precautionary measures against exceeding the
●
maximum permitted pressures caused by pressure
surges (water hammer).
Suitability of the product!
▶ The product must be appropriate for the piping system
