DANGER
Danger due to development of a potentially explosive atmosphere!
Splashing or spraying flammable fluids to clean the container can create a potentially
explosive atmosphere.
There is a risk of death or severe physical injury.
Avoid the creation of a hazardous potentially explosive atmosphere and the activation
of ignition sources.
Explosions with dangerous effects may occur if the following four conditions are met
simultaneously:
–
High level of dispersion of flammable substances,
–
Concentration of flammable substances in the air within the explosive limits,
–
Hazardous quantity of potentially explosive atmosphere,
–
Effective ignition source
Adhere to the regulations and specifications on the safety data sheets for the cleaning
media (e.g. ignition temperature; flash point; explosion limits).
When using flammable cleaning media, the maximum operating temperature of the
cleaning medium must be 15 K below the flash point of the cleaning medium and
must not exceed 60 °C.
The following are PROHIBITED for use as cleaning media:
–
Corrosive or explosive fluids, fluids with solid content (e.g. abrasives) and
substances that can undergo exothermic reactions with the material of the
container or the plant (e.g. chlorine, substances containing chlorine ions or salt)
must not be used for cleaning purposes.
–
Conductive solvents (hydrocarbons) as cleaning media (κ > 10,000 pS/m), such as
alcohols, ketones, glycols, glycol ethers, ethers, ethyl acetate and isopropyl acetate.
To ensure fault-free operation, an upstream filter system with a mesh width of 50 µm
should be fitted.
DANGER
Explosion hazard due to ignition source!
An existing explosive atmosphere could be ignited.
There is a risk of death or severe physical injury.
The cleaning medium and the material to be cleaned must not cause a chemical
reaction that might cause an ignition.
Observe electrostatic charges when handling fluids.
