ABC of Safety in the Biological Sciences
1,2DICHLOROETHANE (CH2ClCH2Cl)
SYNONYMS
Ethylene dichloride, dutch oil, dutch liquid, glycol dichloride.
CHARACTERISTICS
Flammable, clear, colourless liquid with a chloroformlike odour.
INCOMPATIBILITY
Heating produces the toxic gas phosgene. Dichlorethane is
incompatible with nitrogen dioxide, aluminium and potassium and
can react vigorously with oxidising materials.
HEALTH HAZARD DATA
Potential carcinogen. Highly toxic through all routes in low
concentrations. Permanent damage to eyes may result from a
splash. Dermatitis may follow skin contact and inhalation or
ingestion may cause dizziness, nausea and abdominal pain and
there may be permanent liver damage. Unconsciousness may follow
and respiration may cease.
HANDLING and GENERAL PRECAUTIONS
Use a fume hood.
Very toxic through all routes of exposure.
Avoid skin and eye contact.
Avoid inhalation.
Avoid ingestion.
Keep away from heat.
Keep away from water and light.
Keep away from oxidising materials.
Wash hands thoroughly after handling.
This is a very toxic substance. Use a fume hood that will keep
the level of exposure below the recommended threshold limit,
i.e. 50 ppm. If exposure is expected to exceed this level than a
respirator is recommended. Wear protective clothing. A long
sleeved laboratory coat or gown, nitrile rubber gloves, safety
goggles and a face mask as a minimum standard.
TREATMENTS
Skin remove contaminated clothing and immediately wash the
affected area with soap or mild detergent and large amounts of
water until all evidence of the chemical has been removed
(approximately 15 minutes). If irritation persists or dermatitis
develops seek medical attention. Wash contaminated clothing
before reuse.
Eyes immediately wash the affected eye with large amounts of
water until all evidence of the chemical has been removed
(approximately 15 minutes). If irritation persists seek medical
attention.
Inhalation remove from the area of exposure to fresh air. If
breathing has ceased apply artificial respiration. Keep warm and
allow to rest. If respiratory distress persists seek medical
attention.
Ingestion wash out the mouth thoroughly with water and seek
immediate medical advice.
STORAGE
Keep away from heat, moisture and light. Store in a cool, dry
atmosphere in the dark.
DISPOSAL
WEAR:
Rubber gloves, self contained breathing apparatus and laboratory
coat.
SPILLS:
Eliminate all sources of ignition. Absorb on paper towels or
with vermiculite. Place on an iron, glass or plastic dish in a
fume hood. Allow to evaporate. burn the paper or vermiculite.
Wash the site with a soapy solution.
PACKAGE LOTS: Either
1 Pour on to vermiculite, sodium bicarbonate or sand-soda ash
mixture (90/10). If a fluoride is present, add slaked lime to
the mixture. Mix and shovel into paper boxes. place in an open
incinerator, cover with scrap wood and paper then ignite with a
torch or fuse. Stay on the upwind side.
OR
2 Dissolve in a flammable solvent. Spray into a fire box of an
incinerator equipped with an afterburner and scrubber.
