Safety Considerations
Danger
Nitrogen gas (used to purge systems designed with hazardous location
protections) accumulates in the enclosure creating oxygen deficient areas.
Wait at least one minute (for breathable air to enter the enclosure) before
beginning work on internal components.
Caustic agents
and volatile atmospheres
Components may be degraded by exposure to caustic agents or their
vapors. Exposure of the internal components to volatile atmospheres can
present a fire and explosion hazard. To maintain the instrument in safe
working condition, be sure the enclosure is purged and pressurized before
introducing caustic or volatile agents into the surrounding atmosphere.
Damage to the internal components caused by caustic and volatile agents
is not covered by warranty.
Danger
Prevent fire and explosion. Before operating a system in a volatile
atmosphere, be sure the atmosphere inside the enclosure is clear before
applying power to the instrument.
Always follow the procedures for opening the enclosure, powering on and
powering off.
Solvents
containing
halogenated
hydrocarbons
Chlorinated solvents, perfluorochlorinated solvents, and other materials
containing halogenated hydrocarbons are often used as FT-NIR solvents.
The pyrolysis of these solvents by a NIR source may produce
hydrochloric acid (HCl), hydrofluoric acid (HF), or phosgene (COCl
2
).
Hydrochloric acid and hydrofluoric acid are highly corrosive and may cause
accelerated corrosion of the internal components. To maintain the
instrument in safe working condition, be sure the enclosure is purged and
pressurized before introducing solvents into the surrounding atmosphere.
Damage to the internal components caused by solvents is not covered by
warranty.
Warning
Hydrochloric acid, hydrofluoric acid and phosgene are highly toxic and
reactive.
