Label the workplace and surrounding area using characters conforming to
the (German) Accident Prevention Regulation "Chlorination of Water"
(GUV 8.15, appendix 3).
Chlorine dioxide cannot be stored or transported either as a gas or as con‐
centrated aqueous solution due to its explosive nature. Therefore it is only
produced as dilute (see point 1.1.3) aqueous solutions in special systems
for immediate use.
Precipitate the gas with water spray.
Pour sodium thiosulphate solution over escaped solution, then dilute with
lots of water and wash away into the drain system.
Chlorine dioxide itself is not combustible, however it acts in an oxidising
manner. Explosive decomposition at temperatures greater than 100
degrees C. Cool storage tanks with water, precipitate any escaped
chlorine dioxide gas with a water spray. There are no restrictions with
regard to fire extinguishing agents in the event of fires in the vicinity.
See point 1.2.3
0.1 ppm (mL/m 3 ) or 0.3 mg/m
The odour of chlorine dioxide gas is perceptible above a concentration of
around 15 mg/m of air.
