FIRE AND EXPLOSION DATA
========================================================================
Fire:

Autoignition temperature: 413掳C (775掳F)
Flammable limits in air % by volume:
LEL: 6.2; UEL: 15.9
Flammable.
Explosion:
Above flash point, vapor-air mixtures are explosive within flammable limits noted above. Sealed containers may
rupture when heated. Contact with strong oxidizers may cause fire. Vapors can flow along surfaces to distant
ignition source and flash back. Sensitive to static discharge.
Fire Extinguishing Media:
Dry chemical, foam or carbon dioxide. Water spray may be used to keep fire exposed containers cool, dilute spills
to nonflammable mixtures, protect personnel attempting to stop leak and disperse vapors.
Special Information:
In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full
facepiece operated in the pressure demand or other positive pressure mode. Combustion by-products include
phosgene and hydrogen chloride gases.
========================================================================
REACTIVITY DATA
========================================================================
Stability: Stable under ordinary conditions of use and storage. Darkens on exposure to air or light.
Hazardous Decomposition Products:
Emits toxic fumes of phosgene, hydrogen chloride, acetylene, and vinyl chloride when heated to decomposition.
Hazardous Polymerization: Will not occur.
Incompatibilities:
Aluminum or magnesium powder, oxidizing agents, reducing agents, organic peroxides, alkali and alkali earth
metals, nitric acid, caustics, nitrogen tetraoxide, ammonia, and dimethylaminopropylamine.
Conditions to Avoid: Heat, flame, sources of ignition, light and incompatibles.

========================================================================
Emergency Overview
Warning! Flammable liquid and vapor. Harmful if swallowed, inhaled or absorbed through skin. Affects central
nervous system, liver, kidneys, and cardiovascular system. Causes irritation to skin, eyes and respiratory tract.
Possible cancer hazard. May cause cancer based on animal data. Risk of cancer depends on duration and level of
exposure.
Potential Health Effects
Inhalation:
Inhalation of vapors irritates the respiratory tract. May cause headache, weakness, cyanosis, nausea, vomiting, and
diarrhea. These symptoms may be followed by central nervous system effects, liver damage, kidney damage, adrenal
gland damage, cyanosis, weak and rapid pulse and unconsciousness. Death can occur from respiratory and
circulatory failure.
Ingestion:
Causes irritation to the gastrointestinal tract. Symptoms may include nausea, vomiting and diarrhea. Toxic effects
parallel those of inhalation. Doses of 0.5 - 1.0 g/kg can be fatal.
Skin Contact:
Causes irritation, rash and blister formation. Prolonged contact can cause skin burns. Can be absorbed through skin
with toxic effects.
Eye Contact:
Vapors cause eye irritation. Splashes cause severe irritation, possible corneal burns and eye damage.
Chronic Exposure:
Repeated or prolonged exposure may cause weight loss, low blood pressure, jaundice, reduced urinary output,
dermatitis, eye damage and anemia. Dichloroethane is a suspected human carcinogen based on animal data.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or eye problems, or impaired liver, kidney, cardiovascular, neurological or
respiratory function may be more susceptible to the effects of the substance.
========================================================================
FIRST AID MEASURES
========================================================================
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Call a
physician.
Ingestion:
If swallowed, DO NOT INDUCE VOMITING. Give large quantities of water. Never give anything by mouth to an
unconscious person. Get medical attention immediately.
Skin Contact:
Wash skin with soap or mild detergent and water for at least 15 minutes while removing contaminated clothing and
shoes. Wash clothing before reuse. Call a physician.

Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally.
Get medical attention immediately.
========================================================================
PREVENTATIVE MEASURES
========================================================================
Airborne Exposure Limits:
- OSHA Permissible Exposure Limit (PEL):
50 ppm (TWA), 100 ppm (ceiling)
200 ppm (max)/5 min/3 hour
- ACGIH Threshold Limit Value (TLV):
10 ppm (TWA), A4 - not classifiable as a human carcinogen
- NIOSH IDLH:
50 ppm
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne
Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the
contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH
document, "Industrial Ventilation, A Manual of Recommended Practices", most recent edition, for details.
Personal Respirators (NIOSH Approved):
If the exposure limit is exceeded, wear a supplied air, full-facepiece respirator, airlined hood, or full-facepiece self-
contained breathing apparatus. This substance has poor warning properties.
Skin Protection:
Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent
skin contact. Polyvinyl alcohol (PVA) and Viton are recommended materials for personal protective equipment.
Eye Protection:
Use chemical safety goggles and/or a full face shield where splashing is possible. Maintain eye wash fountain and
quick-drench facilities in work area.
Handling and Storage:
Protect against physical damage. Store in a cool, dry well-ventilated location, away from any area where the fire
hazard may be acute. Outside or detached storage is preferred. Separate from incompatibles. Containers should be
bonded and grounded for transfers to avoid static sparks. Storage and use areas should be No Smoking areas. Use
non-sparking type tools and equipment, including explosion proof ventilation. Wear special protective equipment
(Sec. 8) for maintenance break-in or where exposures may exceed established exposure levels. Wash hands, face,
forearms and neck when exiting restricted areas. Shower, dispose of outer clothing, change to clean garments at the
end of the day. Avoid cross-contamination of street clothes. Wash hands before eating and do not eat, drink, or
smoke in workplace. Containers of this material may be hazardous when empty since they retain product residues
(vapors, liquid); observe all warnings and precautions listed for the product.

specified in Section 8. Isolate hazard area. Keep unnecessary and unprotected personnel from entering. Contain and

recover liquid when possible. Use non-sparking tools and equipment. Collect liquid in an appropriate container or
absorb with an inert material (e. G., Vermiculite, dry sand, earth), and place in a chemical waste container. Do not
use combustible materials, such as saw dust. Do not flush to sewer! If a leak or spill has not ignited, use water spray
to disperse the vapors, to protect personnel attempting to stop leak, and to flush spills away from exposures. US
Regulations (CERCLA) require reporting spills and releases to soil, water and air in excess of reportable quantities.

SOLUSORB(R) solvent adsorbent is recommended for spills of this product.
