Most important symptoms/effects, acute and delayed
Excerpt from ERG Guide 160 [Halogenated Solvents]: Toxic by ingestion. Vapors may cause dizziness or suffocation. Exposure in an enclosed area may be very harmful. Contact may irritate or burn skin and eyes. Fire may produce irritating and/or toxic gases. Runoff from fire control or dilution water may cause pollution. (ERG, 2016)
Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Halogenated Aliphatic Hydrocarbons and Related Compounds

SECTION 10: Stability and reactivity
Reactivity
Decomposes on heating. This produces toxic and corrosive fumes including hydrogen chloride, phosgene and hydrogen bromide. Reacts violently with strong oxidants, strong bases and metals such as sodium, potassium, magnesium and powdered aluminium. This generates fire and explosion hazard. Attacks some forms of rubber, plastics and coatings.
Chemical stability
Chemical stability: Stable under recommended storage conditions. Contains the following stabilizer(s): BHT (<=100 ppm)
Possibility of hazardous reactions
No flash or fire points by standard tests in air.The vapour is heavier than air.BROMOCHLOROMETHANE is sensitive to light (may discolor). Incompatible with strong bases and strong oxidizing agents. Also incompatible with active metals, calcium, aluminum, magnesium, zinc and their alloys. Attacks some forms of plastics, rubber and coatings. (NTP, 1992).
Conditions to avoid

Carcinogenicity
CLASSIFICATION: D; not classifiable as to human carcinogenicity. BASIS FOR CLASSIFICATION: Based on the lack of data regarding the carcinogenicity of bromochloromethane in humans or animals; however, there are data indicative of genotoxic effects and structural relationships to halogenated methanes classified as B2 probable human carcinogens. HUMAN CARCINOGENICITY DATA: None. ANIMAL CARCINOGENICITY DATA: None.
Reproductive toxicity
no data available
STOT-single exposure
The vapour is irritating to the eyes, skin and respiratory tract. If swallowed the substance may cause vomiting and could result in aspiration pneumonitis. Inhalation of high concentrations of the vapour may cause lung oedema. See Notes. Exposure at high concentrations could cause lowering of consciousness. Exposure could cause carbon monoxide poisoning. This may result in impaired functions. The effects may be delayed.
STOT-repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the central nervous system and liver.
Aspiration hazard
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C.

Persistence and degradability
AEROBIC: Bromochloromethane, present at 100 mg/L, reached 0% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). In a screening test, bromochloromethane at an initial concentration of 5 or 10 mg/L underwent 100% degradation within seven days using an adapted settled domestic wastewater inoculum under aerobic conditions(2,3). Complete degradation ensued with 3 successive subcultures(2,3).
Bioaccumulative potential
An estimated BCF of 4 was calculated for bromochloromethane(SRC), using a log Kow of 1.41(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low.
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of bromochloromethane can be estimated to be 22(SRC). According to a classification scheme(2), this estimated Koc value suggests that bromochloromethane is expected to have very high mobility in soil. The partition coefficient of bromochloromethane between a sandy loam soil and water was 0.2497(3). The electrostatic attraction between negatively charged clay particle and charged carbon atom is hypothesized to be the prime adsorption mechanism of halogenated organic contaminants to a sandy loam. The negative charge on the halogen atoms repels negatively charged soil particles(3).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.

Other Information
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential.
