Potential Health Effects
----------------------------------
Inhalation:Causes irritation to the respiratory tract. Symptoms may
include coughing, shortness of breath. High concentrations can cause pulmonary
edema.
Ingestion:Toxic. Suspected of causing liver damage. Will produce hydrogen
sulfide in stomach which can be fatal.
Skin Contact:Causes irritation to skin. Symptoms include redness,
itching, and pain. Can be corrosive. May decompose to hydrogen sulfide on
contact with the skin. Decomposition product acetonitrile can be absorbed
through the skin.
Eye Contact:Causes irritation, redness and pain. Can be corrosive to
eyes; may decompose to hydrogen sulfide in contact with eye.
Chronic Exposure:May cause liver damage. Material is a suspected human
carcinogen.
Aggravation of Pre-existing Conditions:No information found.
Inhalation:Remove to fresh air. If not breathing,
give artificial respiration. If breathing is difficult, give oxygen. Get medical
attention.
Ingestion:Induce vomiting immediately as directed by medical personnel.
Never give anything by mouth to an unconscious person.
Skin Contact:Immediately flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Get medical attention.
Wash clothing before reuse. Thoroughly clean shoes before reuse.
Eye Contact:Immediately flush eyes with plenty of water for at least 15
minutes, lifting upper and lower eyelids occasionally. Get medical attention.
Fire:As with most organic solids, fire is possible
at elevated temperatures or by contact with an ignition source.
Explosion:Fine dust dispersed in air in sufficient concentrations, and in
the presence of an ignition source is a potential dust explosion hazard. Do not
cut, drill, weld or grind on or near container: explosive hazard.
Fire Extinguishing Media:Dry chemical, foam or carbon dioxide. Do not use
water.
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.
Remove all sources of ignition. Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8. Spills: Clean up spills in a manner that does not disperse dust into the air. Use non-sparking tools and equipment. Reduce airborne dust and prevent scattering by moistening with water. Pick up spill for recovery or disposal and place in a closed container. US Regulations (CERCLA) require reporting spills and releases to soil, water and air in excess of reportable quantities.
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Isolate from any source of heat or ignition. Isolate from acids and alkalis. 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 (dust, solids); observe all warnings and precautions listed for the product.
Airborne Exposure Limits:None established.
Ventilation System:A system of local and/or general exhaust is
recommended to keep employee exposures as low as possible. 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):For conditions of use where
exposure to dust or mist is apparent and engineering controls are not feasible,
a particulate respirator (NIOSH type N95 or better filters) may be worn. If oil
particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present, use a
NIOSH type R or P filter. For emergencies or instances where the exposure levels
are not known, use a full-face positive-pressure, air-supplied respirator.
WARNING: Air-purifying respirators do not protect workers in oxygen-deficient
atmospheres.
Skin Protection:Wear impervious protective clothing, including boots,
gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact.
Eye Protection:Use chemical safety goggles and/or full face shield where
dusting or splashing of solutions is possible. Maintain eye wash fountain and
quick-drench facilities in work area.

Environmental Fate:When released into the soil, this
material may leach into groundwater. When released into water, this material may
biodegrade to a moderate extent. When released into water, this material is not
expected to evaporate significantly. This material is not expected to
significantly bioaccumulate. When released into the air, this material may be
moderately degraded by photolysis.
Environmental Toxicity:No information found.
