EMERGENCY OVERVIEW
Appearance: clear, colorless to pale yellow liquid.
Warning! Harmful if swallowed. Causes eye, skin,
and respiratory tract irritation. May cause liver and kidney damage.
May cause central nervous system effects.
Target Organs: Blood, kidneys, central nervous
system, liver, respiratory system, eyes, skin.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation. Prolonged and/or repeated contact may cause
irritation and/or dermatitis.
Ingestion:
Harmful if swallowed. Causes gastrointestinal irritation with
nausea, vomiting and diarrhea. Aspiration of material into the lungs
may cause chemical pneumonitis, which may be fatal.
Inhalation:
Causes respiratory tract irritation. May cause severe irritation of
the respiratory tract with sore throat, coughing, shortness of
breath and delayed lung edema.
Chronic:
May cause liver and kidney damage. Prolonged exposure may produce a
narcotic effect.
|
Section 4 - First Aid Measures
|
Eyes:
In case of contact, immediately flush eyes with plenty of water for a
t least 15 minutes. Get medical aid.
Skin:
In case of contact, flush skin with plenty of water. Remove
contaminated clothing and shoes. Get medical aid if irritation
develops and persists. Wash clothing before reuse.
Ingestion:
Potential for aspiration if swallowed. Get medical aid immediately.
Do not induce vomiting unless directed to do so by medical
personnel. Never give anything by mouth to an unconscious person. If
vomiting occurs naturally, have victim lean forward.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
|
Section 5 - Fire Fighting Measures
|
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Use water
spray to keep fire-exposed containers cool.
Extinguishing Media:
Use dry chemical, carbon dioxide, or appropriate foam.
Flash Point: None.
Autoignition Temperature: Not applicable.
Explosion Limits, Lower:Not available.
Upper: Not available.
NFPA Rating:
(estimated) Health: 2; Flammability: 0; Instability: 0
|
Section 6 - Accidental Release Measures
|
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Avoid runoff into storm sewers and
ditches which lead to waterways. Clean up spills immediately,
observing precautions in the Protective Equipment section. Provide
ventilation.
|
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Avoid contact with
eyes, skin, and clothing. Avoid breathing vapor. Due to the tendency
of dibromomethane to hydrolyze and form acid on exposure to water,
the material should be kept dry. Also for this reason, the use of
unlined carbon steel for storage vessels is not recommended.
Storage:
Store in a cool, dry, well-ventilated area away from incompatible
substances. Store protected from moisture. Store protected from
light and air.
|
Section 8 - Exposure Controls, Personal Protection
|
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use process enclosure,
local exhaust ventilation, or other engineering controls to control
airborne levels.
