WARNING
• This product is not an explosion-proof product.
It ignites and causes a fire.
Since this instrument includes electrically active parts even if the power switch is off, it ignites and
causes a fire if there are any flammable gases in explosive (flammable) range around this instrument.
Do not leave the material that generates the flammable gas around this instrument.
Maximum 10 L/min. of the purge gas is used to purge the FTIR.
Take measures to prevent hypoxia in accordance with the local laws/regulations of the region in
which the instrument is installed:
• Ventilate the room by opening windows or using ventilation fans during purging or after purging.
• Avoid purging in a sealed room.
• For safety reasons, Shimadzu recommends the use of the oxygen indicator along with the product
introduced in this manual. The following is the recommended portable oxygen indicator.

CAUTION
If vapors of any organic halide, such as difluoromethane (CH
2
F
2
), dichloromethane (CH
2
Cl
2
), chloroform
(CHCl
3
), or carbon tetrachloride (CCl
4
) enter the interferometer, they are decomposed by the heat of the light
source to highly caustic hydrogen halides such as Hydrofluoric acid (HF), Hydrochloric acid (HCl), etc.
Mirrors, other optical elements, screws and another parts in the interferometer might be damaged. Please
prevent the entry of organic halide vapors into the interferometer by installing a local ventilation system at the
FTIR sample compartment, or purging the interferometer with dried air or N
2
gas, when you run samples that
include volatile organic halide compounds.
