Guidance on Safe Use
Administrative data
First-aid measures
Emergency measure - Inhalation: Remove the person from exposed area to fresh area
immediately. Get medical advice immediately after
significant exposure.
Emergency measure - Eyes: Wash immediately with large amounts of water or normal
saline; keep the eyelid open with the finger. If irritation
synthom appears, get medical advice as soon as possible.
Emergency measure - Skin: Remove contaminated clothes and shoes immediately. Wash
affected area with soap or mild detergent and large amount
of water until no evidence of chemical remains (15-20
minutes). Get medical attention as soon as possible if
synthom persists.
Emergency measure - Ingestion: If swallowed wash out mouth with water provided person is
conscious. Treat symptomatically and supportively. Get
medical advice immediately.
Fire-fighting measures
Recommended extinguishing agent: Water, CO2, foam, dry powders
Product arising from burning: Carbon oxide, Chloride
Product determined by test: N
