Safety Instructions
GASES AND PREPARATION OF GASES
GASES HAZARDOUS TO HEALTH
Follow the safety precautions for all gases (sample and span gases) and
gas cylinders.
Before opening the gas lines, they must be purged with air or neutral gas
(N
2
) to avoid danger from escaping toxic, ammable, exposive or hazardous
gases.
EXPLOSIVE GASES
When supplying ammable gases with concentrations of more than ¼ of
the lower explosion limit, we RECOMMEND implementing one or more
additional safety measures:
• purging the unit with inert gas
• stainless steel internal pipes
• ame arrestors on gas inlets and outlets
• inherently safe or failsafe measuring cells
OPERATION AT LOW TEMPERATURES
When operating an instrument at temperatures below 0 °C (32 °F), do
NOT apply gas nor operate the internal pump before the warmup time has
elapsed!
Violation may result in condensation inside the gas paths or damaged pump
diaphragm!
