5. Fire-fighting measures
5.1 Extinguishing media
Suitable extinguishing media
. Cover skin burns with dry sterile
Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: SMALL FIRE: Dry
chemical, CO2, water spray or regular foam. LARGE FIRE: Water spray, fog or regular
foam. Do not scatter spilled material with high-pressure water streams. Move containers
from fire area if you can do it without risk. Dike fire-control water for later disposal. FIRE
INVOLVING TANKS: Cool containers with flooding quantities of water until well after fire is
out. Withdraw immediately in case of rising sound from venting safety devices or
discoloration of tank. ALWAYS stay away from tanks engulfed in fire. (ERG, 2016)
5.2 Specific hazards arising from the chemical
Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]: Some may burn but none ignite readily. Containers may explode when heated. Some may be transported hot. For UN3508, be aware of possible short circuiting as this product is transported in a charged state. (ERG, 2016)
5.3 Special protective actions for fire-fighters
Wear self-contained breathing apparatus for firefighting if necessary.
