2.5.1 Potentially explosive area
DANGER!
Mortal danger due to explosion!
Observe the additional ATEX instructions!
2.5.2 Hazardous pumped medium
nWhen handling hazardous pumped medium (e.g. hot, flammable, explosive,
toxic, harmful to health) observe the safety regulations applicable to the han-
dling of hazardous substances safety datasheets).
nUse personal protective equipment during all work on the pump.
nEnsure sufficient ventilation or extraction.
2.5.3 Concentration of natural radioactivity
WARNING!
Damage to health due to naturally occurring radioactive waves!
– Natural gas or oil fields can contain substances that are natu-
rally radioactive.
– If the natural radioactivity of the raw materials is enriched during
pumping/extraction (e.g. as a result of precipitation or by accu-
mulation), it is not possible to rule out damage to health through
the absorption/ingestion of naturally radioactive solid particles.
– Wear suitable personal protective equipment.
– Observe all of the protective measures relevant to radioactivity.
nUse the appropriate measuring equipment in order to measure the natural
radioactivity.
nInform everyone who enters the affected area.
nNotify the responsible authority.
nPersons with skin injuries must not work in potentially contaminated areas.
nWear a respiratory mask in the affected areas and do not enter other areas.
nDo not handle naturally radioactive substances for longer than necessary.
nKeep as far away as possible from these substances.
nDo not open contaminated plant components unless you are wearing protec-
tive clothing.
nWash yourself thoroughly with soap and water every time you work in this
area.
nContaminated clothing and/or contaminated plant components must be prop-
erly decontaminated or disposed of.
nAll components that come into contact with media must potentially be taken
into consideration.
nTaking radioactive substances (e.g. filtrate) into other areas must be avoided
under all circumstances.
