IGNITION SPARKS CAUSED BY EJECTED PARTS
• Verify that your risk assessment includes all events and causes which may
provoke ignition sparks as a result of ejected parts.
Failure to follow these instructions will result in death or serious injury.
Vibration, leaks at connections at the pressure gauge and/or the measuring
line, bursting of the pressure gauge, incorrect installation, fatigue of material
and other causes may provoke medium to escape. Escaping medium can
cause serious hazards, in particular in the case of flammable substances,
explosive substances, toxic substances and other hazardous substances.
ESCAPING MEDIUM
• Verify that your risk assessment includes all events and causes which may
provoke medium to escape.
• Verify that escaping medium can be safely collected and/or discharged.
• Verify that all pressurised parts and connections of the pressure gauge and
the measuring line are sealed and function correctly by using approved test
methods at regular intervals.
• Immediately replace damaged pressure gauges.
Failure to follow these instructions can result in death, serious injury or
equipment damage.
As per EN 837, liquid-filled pressure gauges must have a blow-out device
(version S1, S2 or S3 as per EN 837-1).
Pressure gauges for oxygen and acetylene must be safety pressure gauges
(version S2 or S3 as per EN 837-1 or pressure gauges as per ISO 5171). All
wetted parts must comply with EN 29539 and must be free from oil and
grease. Only lubricants suitable for oxygen at maximum operating pressure
may be used. The pressure gauges must never be exposed to humidity.
Pressure gauges with glycerine filling must not be used for oxygen or other
oxidising process media. High-concentration fluorine liquids and chlorinated
liquids (for example, halocarbon) as filling liquid are suitable for such appli-
cations.
