Hazard Control Recommended
Maintenance:
Changing the H2S
sensing Tape
(Acetate Tape)
Operator(s) Long term exposure
(through skin and
inhaling) could
potentially cause
cancer and other
health problems - Not
an immediate safety
risk
Due to the long term health
effects of Lead which is contained
in the H2S Acetate tape, the
operator is recommended to wear
gloves & mask when handling the
tape. If gloves where not worn,
hands must be properly washed
with soap and water
As an overall practice when doing
maintenance into an H2S
analyzer, the operator should
carry a personal H2S monitor,
wear a hard hat, hearing
protection (if applicable), safety
glasses, hand protection, steel
toed boots. Depending on the
location of the H2S analyzer,
appropriate breathing device
might be required such as SCBA
(Self-contained Breathing
Apparatus) and SABA (Supplied
Air Breathing Apparatus)
Maintenance:
Changing filter in
SCS
Operator(s) Potential safety risk -
release of gases at a
high pressure level
can cause serious
injuries
Due to the fact that the filter is
located before the pressure
regulator, the operator could be
dealing with pressures up to 3600
PSI. The operator must isolate
the sample system before
changing the filter
