Potential Health Effects
----------------------------------
Inhalation:
No adverse health effects via inhalation.
Ingestion:
Relatively non-toxic. Ingestion of sizable amount (over 100ml) may cause
some gastrointestinal upset and temporary central nervous system
depression. Effects appear more severe in individuals with kidney
problems.
Skin Contact:
Mild irritant and defatting agent, especially on prolonged contact.
Eye Contact:
May cause transitory stinging and tearing.
Chronic Exposure:
Lactic acidosis, stupor and seizures have been reported following chronic
ingestion.
Aggravation of Pre-existing Conditions:
Kidney disorders.
4. First Aid Measures
Inhalation:
Remove to fresh air. Not expected to require first aid measures.
Ingestion:
Not expected to require first aid measures. Give several glasses of water
to drink to dilute. If large amounts were swallowed, get medical advice.
Skin Contact:
Remove any contaminated clothing. Wash skin with soap and water for at
least 15 minutes. Get medical attention if irritation develops or persists.
Eye Contact:
In case of contact, immediately flush eyes with plenty of water for at
least 15 minutes, lifting upper and lower eyelids occasionally. Call a
physician if irritation persists.
Note to Physician:
In case of ingestion, monitor for acidosis and central nervous system
changes. Exposed persons with previous kidney dysfunction may require
special treatment.
5. Fire Fighting Measures
Fire:
Flash point: 99C (210F) CC
Autoignition temperature: 371C (700F)
Flammable limits in air % by volume:
lel: 2.6; uel: 12.5
Material can support combustion.
Explosion:
Containers may explode in heat or fire.
Fire Extinguishing Media:
Dry chemical, foam, water or carbon dioxide.
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. Move exposed containers
from fire area, if it can be done without risk. Use water to keep
fire-exposed containers cool.
6. Accidental Release Measures
Ventilate area of leak or spill. Remove all sources of ignition. Wear
appropriate personal protective equipment as 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!
7. Handling and Storage
Protect container from physical damage. Store in a cool, dry, ventilated
area away from sources of heat, moisture, and incompatible substances.
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.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
AIHA Workplace Environmental Exposure Level (WEEL): Vapor and Aerosol
= 50ppm; Aerosol, only = 10mg/m3.
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, a half-face respirator with an organic
vapor cartridge and dust/mist filter may be worn for up to ten times the
exposure limit or the maximum use concentration specified by the
appropriate regulatory agency or respirator supplier, whichever is lowest.
A full-face piece respirator with an organic vapor cartridge and dust/mist
filter may be worn up to 50 times the exposure limit, or the maximum use
concentration specified by the appropriate regulatory agency or respirator
supplier, whichever is lowest. For emergencies or instances where the
exposure levels are not known, use a full-face piece positive-pressure,
air-supplied respirator. WARNING: Air-purifying respirators do not protect
workers in oxygen-deficient atmospheres.
Skin Protection:
Wear protective gloves and clean body-covering clothing.
Eye Protection:
Use chemical safety goggles. Maintain eye wash fountain and quick-drench
facilities in work area.

12. Ecological Information
Environmental Fate:
When released into the soil, this material is expected to readily
biodegrade. When released into the soil, this material is expected to leach
into groundwater. When released into water, this material is expected to
readily biodegrade. When released into the air, this material is expected
to be readily degraded by reaction with photochemically produced hydroxyl
radicals. When released into the air, this material is expected to have a
half-life between 1 and 10 days.
