Necessary Precautions During ICP-MS Operation
Other Gas
WARNING
The following are general precautions that should be taken during ICP-MS operation
to prevent combustion of hydrogen gas. Other precautions may be necessary
depending on the setting and configuration in which you use the system. Pay careful
attention to safety management when using this system.
• Make sure the hydrogen gas line is without leaks.
• Periodically check equipment for hydrogen leaks using the appropriate devices
(leak detector, soapy solution, etc.).
• Eliminate from your laboratory as many ignition sources as possible (open
flames, devices that can spark, sources of static electricity, etc.)
• Do not vent hydrogen from a high-pressure chamber directly into the atmosphere.
There is a danger the gas will self-ignite.
• Always turn off the hydrogen gas at its source whenever you turn off the ICP-MS.
• Always turn off the hydrogen gas at its source before opening the vent valve or
otherwise introducing ambient air into the ICP-MS. Hydrogen gas can
concentrate and combust at atmospheric pressure.
• Turn off the hydrogen gas at its source as soon as a power failure occurs. Do not
resume operation of the ICP-MS before inspecting it for damage or irregularities.
• The exhaust duct should always be operating. Hydrogen gas released while the
exhaust duct is not operating can result in accumulation of the gas in the ICP-MS
and/or the exhaust duct.
CAUTION
Gases must be handled with care.
• Refer to the MSDS (Material Safety Data Sheet) for safe handling information.
• Check for gas leaks periodically using the appropriate tools (leak detector, soapy
water, etc.)
