SECTION 10: Stability and reactivity
Reactivity
NIOSH considers hexachlorobutadiene to be a potential occupational carcinogen.
Decomposes on burning. This produces toxic and corrosive fumes including hydrogen chloride (see ICSC 0163) and phosgene (see ICSC 0007). Attacks rubber and some forms of plastic.
Chemical stability
no data available
Possibility of hazardous reactions
Combustible when exposed to heat or flame; can react vigorously with oxidizing materials.HEXACHLOROBUTADIENE rapidly decomposes rubber on contact. Can react vigorously with oxidizing materials. Reacts to form an explosive product with bromine perchlorate. (NTP, 1992). Gives highly toxic and irritating chloride fumes when burned.
Conditions to avoid
no data available
Incompatible materials
Oxidizers.
Hazardous decomposition products
When heated to decomposition it emits very toxic fumes of /chlorine/ Cl-.

Carcinogenicity
EPA: Possibly carcinogenic to humans. IARC: Not classifiable as to carcinogenicity to humans. NTP: Not evaluated
Reproductive toxicity
No information is available regarding the developmental or reproductive effects of hexachlorobutadiene in humans. One study reported that the frequency of abnormal sperm morphology did not increase significantly over controls in mice exposed to hexachlorobutadiene via inhalation. A study in rats exposed via inhalation reported no embryotoxic effects, except for a reduction in fetal body weights. Oral animal studies have reported reduced fertility, reduced fetal body weights, but no birth defects or other developmental effects from hexachlorobutadiene exposure.
STOT-single exposure
The substance is irritating to the eyes, skin and respiratory tract. The liquid is corrosive. The substance may cause effects on the kidneys.
STOT-repeated exposure
Repeated or prolonged contact may cause skin sensitization. May cause genetic damage in humans.
Aspiration hazard
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C.

- Toxicity to daphnia and other aquatic invertebrates: no data available
- Toxicity to algae: no data available
- Toxicity to microorganisms: no data available
Persistence and degradability
AEROBIC: Hexachloro-1,3-butadiene may biodegrade in natural waters since 100% degradation occurred in 7 days in an aerobic batch culture incubated at 25 deg C and inoculated with settled domestic sewage(1). Estimated half-lives for hexachloro-1,3-butadiene disappearance based on monitoring data are 3-30 days in river water and 30-300 days in lake and ground waters(2). ANAEROBIC: Greater than 99% of hexachloro-1,3-butadiene transformed to (E,E)-1,2,3,4-tetrachlorobutadiene by reductive dechlorination in columns with Rhine sediment (Germany) operated at 20 deg C with methanogenic electron acceptors(3). Hexachloro-1,3-butadiene was only removed under methanogenic conditions using these sediments and not when oxygen or nitrate were present in the column experiments(4). Reductive dechlorination in the column was ascribed to the activity of anaerobic microorganisms(4).
Bioaccumulative potential
The mean bioconcentration factor (BCF) for rainbow trout exposed to 0.10 ng/l and 3.4 ng/l of hexachloro-1,3-butadiene was 5,800 and 17,000, respectively(1). The BCF for fathead minnow exposed to hexachloro-1,3-butadiene was 6,918(2). According to a classification scheme(3), these BCF values suggest bioconcentration in aquatic organisms is very high. The mean bioconcentration factor for hexachloro-1,3-butadiene between oligocheate worms and sediment in Lake Ontario near the Niagara River was 0.43(4). The concn of the chemical in the sediment pore water was the main factor affecting bioconcentration(4).
Mobility in soil
The Koc of hexachloro-1,3-butadiene ranges from 5.02X10+3 to 2.75X10+5(1-3). According to a classification scheme(4), these Koc values suggest that hexachloro-1,3-butadiene has slight to no mobility in soil(SRC).
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.
