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.
Voltage hazards Operator(s) Immediate safety and
health risk.
It is important that the operator is
trained on handling the analyzer
when it is on. The analyzer does
not need to be off when it goes
into maintenance. However, it is
very important that the operator is
aware of the danger of an electric
shock
TS Enclosure heat Operator(s) Medium safety risk The inside of the Total Sulfur
Enclosure can get up to 900 °C,
however, the outside walls will
only reach approximately 150 °C.
Do not touch surface of the TS
enclosure when operating. If the
TS enclosure needs to be
serviced, allow 1 hour after
powering down the analyzer to
cool down
