EMERGENCY OVERVIEW
Appearance: white crystalline powder.
Danger! Contact with water liberates corrosive
vapors. Strong oxidizer. Contact with other material may cause a
fire. Causes eye, skin, and respiratory tract irritation. May be
harmful if swallowed. Moisture sensitive.
Target Organs: Respiratory system, eyes, skin.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation.
Ingestion:
Causes gastrointestinal irritation with nausea, vomiting and
diarrhea. May be harmful if swallowed.
Hemorrhages of the GI tract.
Inhalation:
Causes respiratory tract irritation. The toxicological properties of
this substance have not been fully investigated.
Chronic:
Repeated inhalation may cause chronic bronchitis.
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 immediately.
Skin:
Get medical aid immediately. In case of contact, immediately wipe
away excess material with a dry cloth while removing contaminated
clothing and shoes. Under safety shower, wash affected areas
thoroughly with large amounts of water, and soap if available, for at
least 15 minutes. Discard or decontaminate clothing and shoes.
Ingestion:
If swallowed, do NOT induce vomiting. Get medical aid immediately.
If victim is fully conscious, give a cupful of water. Never give
anything by mouth to an unconscious person.
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. Strong oxidizer. Contact with other material may
cause fire. During a fire, irritating and highly toxic gases may be
generated by thermal decomposition or combustion.
Extinguishing Media:
Do NOT get water inside containers. Use dry chemical, carbon
dioxide, or halon extinguisher.
Flash Point: 191 deg C ( 375.80 deg F)
Autoignition Temperature: Not available.
Explosion Limits, Lower:Not available.
Upper: Not available.
NFPA Rating:
(estimated) Health: 3; Flammability: 1; Instability: 0; Special Hazard: OX
Section 6 - Accidental Release Measures
|
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective
Equipment section. Sweep up, then place into a suitable container for
disposal. Avoid generating dusty conditions. Provide ventilation. Do
not get water inside containers.
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Avoid contact with eyes, skin, and clothing. Keep
container tightly closed. Avoid ingestion and inhalation. Use with
adequate ventilation. Do not allow contact with water. Keep from
contact with clothing and other combustible materials. Keep from
contact with moist air and steam.
Storage:
Keep container closed when not in use. Store in a tightly closed
container. Store in a cool, dry, well-ventilated area away from
incompatible substances. Store protected from moisture. DCDMH can be
stored without significant loss of chlorine. At 60°C after 14 weeks,
chlorine loss was 1.5%.
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 adequate
ventilation to keep airborne concentrations low.
