Eye/face protection
Safety glasses with side-shields conforming to EN166. Use equipment for eye protection tested and approved under appropriate government
standards such as NIOSH (US) or EN 166(EU).
Skin protection
Wear impervious clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous
substance at the specific workplace. Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique(without
touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable
laws and good laboratory practices. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive

10.Stability and reactivity
10.1 Reactivity
no data available
10.2 Chemical stability
Stable under recommended storage conditions.
10.3 Possibility of hazardous reactions
NOT FLAMMABLE BY STANDARD TEST IN AIRThe vapour is heavier than air.Halogenated aliphatic compounds, such as
DIBROMOMETHANE, are moderately or very reactive. Halogenated organics generally become less reactive as more of their hydrogen atoms
are replaced with halogen atoms. Low molecular weight haloalkanes are highly flammable and can react with some metals to form dangerous
products. Materials in this group are incompatible with strong oxidizing and reducing agents. Also, they are incompatible with many amines,
nitrides, azo/diazo compounds, alkali metals (potassium), and epoxides.
10.4 Conditions to avoid
no data available
10.5 Incompatible materials
Although apparently stable on contact, mixtures of potassium (or its alloys) with a wide range of halocarbons are shock-sensitive & may explode
with great violence on light impact. Chloroethane, dichloroethane ... dibromomethane & diiodomethane are among those investigated. Sensitivity
increases generally with the degree of substitution ...
10.6 Hazardous decomposition products

12.3 Bioaccumulative potential
An estimated BCF of 4.06 was calculated for dibromomethane(SRC), using a log Kow of 1.70(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.

Using a structure estimation method based on molecular connectivity indices(1), the Koc for dibromomethane can be estimated to be 24(SRC).
According to a classification scheme(2), this estimated Koc value suggests that dibromomethane is expected to have very high mobility in soil.
12.5 Other adverse effects

13.Disposal considerations
13.1 Disposal methods
Product
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.
Contaminated packaging
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.
