Potential Health Effects
----------------------------------
Inhalation:
Due to the low vapor pressure, inhalation of the vapors at room temperatures
is unlikely. Inhalation of mist may cause irritation of respiratory tract.
Ingestion:
Low toxicity. May cause nausea, headache, diarrhea.
Skin Contact:
May cause irritation.
Eye Contact:
May cause irritation.
Chronic Exposure:
May cause kidney injury.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or eye problems or impaired liver or
kidney function may be more susceptible to the effects of the substance.
4. First Aid Measures
Inhalation:
Remove to fresh air. Get medical attention for any breathing difficulty.
Ingestion:
Induce vomiting immediately as directed by medical personnel. Never give anything
by mouth to an unconscious person. Get medical attention.
Skin Contact:
Immediately flush skin with plenty of water for at least 15 minutes. Remove
contaminated clothing and shoes. Wash clothing before reuse. Thoroughly clean
shoes before reuse. Get medical attention if irritation develops.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes, lifting
upper and lower eyelids occasionally. Get medical attention if irritation persists.
5. Fire Fighting Measures
Fire:
Flash point: 199C (390F) CC
Autoignition temperature: 370C (698F)
Slight fire hazard when exposed to heat or flame.
Explosion:
Above flash point, vapor-air mixtures are explosive within flammable limits
noted above.
Fire Extinguishing Media:
Use any means suitable for extinguishing surrounding fire. Water spray may be
used to extinguish surrounding fire and cool exposed containers. Water spray
will also reduce fume and irritant gases.
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.
6. Accidental Release Measures
Ventilate area of leak or spill. Wear appropriate personal protective equipment
as specified in Section 8. Contain and recover liquid when possible. 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
Keep in a tightly closed container, stored in a cool, dry, ventilated area.
Protect against physical damage. Isolate from 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:
For Glycerin Mist:
- OSHA Permissible Exposure Limit (PEL):
Total Dust: 15 mg/m3 (TWA);
Respirable Fraction: 5 mg/m3(TWA).
- ACGIH Threshold Limit Value (TLV):
10 mg/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 and engineering controls are not feasible,
a half facepiece particulate respirator (NIOSH type P95 or R95 filters) 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 particulate respirator (NIOSH type P100 or R100
filters) 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. Please note that N filters are not recommended for this material.
For emergencies or instances where the exposure levels are not known, use a
full-facepiece 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.

10. Stability and Reactivity
Stability:
Stable under ordinary conditions of use and storage.
Hazardous Decomposition Products:
Toxic gases and vapors may be released if involved in a fire. Glycerin decomposes
upon heating above 290C, forming corrosive gas (acrolein).
Hazardous Polymerization:
Will not occur.
Incompatibilities:
Strong oxidizers. Can react violently with acetic anhydride, calcium oxychloride,
chromium oxides and alkali metal hydrides.
Conditions to Avoid:
Heat, flames, ignition sources and incompatibles.

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 not expected to evaporate significantly.
When released into water, this material is expected to readily biodegrade. This
material is not expected to significantly bioaccumulate. When released into
the air, this material may be moderately degraded by reaction with photochemically
produced hydroxyl radicals. When released into the air, this material may be
removed from the atmosphere to a moderate extent by wet deposition.
Environmental Toxicity:
This material is not expected to be toxic to aquatic life.
13. Disposal Considerations
Whatever cannot be saved for recovery or recycling should be managed in an appropriate
and approved waste disposal facility. Processing, use or contamination of this
product may change the waste management options. State and local disposal regulations
may differ from federal disposal regulations. Dispose of container and unused
contents in accordance with federal, state and local requirements.
