Supplemental label elements

In contact with water releases gases which are toxic if Contact with water or moist air liberates white fumes inhaled. and corrosive/irritating gas. Do not breathe these fumes. Obtain special instructions before use. Do not handle until all safety instructions have been read and understood. Transfer and use only in closed and sealed equipment. Emergency Overview: A non-combustible, colourless, fuming liquid with a pungent, acidic odour. Reacts violently with water or moist air to produce visible white fumes containing hydrochloric acid vapour, a severe respiratory irritant and severe eye irritant which can be fatal if inhaled at high concentrations. Firefighters responding to an accidental release must always wear a self- contained breathing apparatus and full protective clothing, including chemical safety goggles. Use water spray or fog nozzles to knock down vapours or fumes and avoid directing water streams into spilled product pools whenever possible.

Potential health effects

A severe skin, eye and mucous membrane irritant. Inhalation of fumes may cause mild to severe irritation of the upper airways, depending on the concentration. Ingestion will result in irritation and may result in serious chemical burns to the mouth, throat (esophagus) and stomach. This material is not listed as a human carcinogen by OSHA, NTP, ACGIH, IARC or the EU (see Toxicological Information, Section 11).

Environmental effects

Although the ecological hazards of this chemical have not been fully investigated, it should be assumed to be a significant toxicant to aquatic and terrestrial organisms. Contact with water or moisture in soil and organisms has the potential to result in the generation of hydrochloric acid (see Ecological Information, Section 12).
