Hydrogen Safety

 

Hydrogen gas may be used as carrier gas, and/or as fuel for certain GC

 

detectors. When mixed with air, hydrogen can form explosive mixtures.

 

A detailed discussion of hydrogen safety appears in Chapter 1 of the Agilent

 

5975 MSD Troubleshooting and Maintenance Manual. Read this material

 

before using hydrogen with the MSD.

 

When using hydrogen (H2) as the carrier gas or fuel gas, be aware that hydrogen

WA R N I N G

 

gas can flow into the oven and create an explosion hazard. Therefore, be sure that

 

 

the supply is off until all connections are made, and ensure that the GC inlet and

 

detector column fittings are either connected to a column or capped at all times

 

when hydrogen gas is supplied to the instrument.

 

Hydrogen is flammable. Leaks, when confined in an enclosed space, may create a

 

fire or explosion hazard. In any application using hydrogen, leak test all

 

connections, lines, and valves before operating the instrument. Always turn off the

 

hydrogen supply at its source before working on the instrument.

 

 

 

The MSD cannot detect leaks in gas streams. For this reason, it is vital that column

WA R N I N G

fittings should always be either connected to a column, or have a cap or plug

 

 

installed.

 

 

 

When using hydrogen gas, check the system for leaks as described by your

 

local Environmental Health and Safety (EHS) requirements to prevent

 

possible fire and explosion hazards. Always check for leaks after changing a

 

tank or servicing the gas lines. Always make sure the vent line is vented into a

 

fume hood.
