J.T. Baker SAF-T-DATA(tm) Ratings (Provided here for your convenience) ----------------------------------------------------------------------------------------------------------- Health Rating: 1 - Slight Flammability Rating: 1 - Slight Reactivity Rating: 0 - None Contact Rating: 1 - Slight Lab Protective Equip: GOGGLES; LAB COAT Storage Color Code: Orange (General Storage) ----------------------------------------------------------------------------------------------------------- Potential Health Effects
----------------------------------
Inhalation:
Causes irritation to the respiratory tract. Exposure may cause an allergy to develop.
Ingestion:
Extremely large oral doses may cause mild burning pain in the mouth and stomach, anorexia, nausea, vomiting,
intense thirst, diarrhea, dizziness, irritability, confusion, coma, teratogenic effects, and death from respiratory
failure. The mean lethal dose of aspirin by mouth probably lies between 20 and 30 grams in adults.
Skin Contact:
May cause irritation.
Eye Contact:
Causes irritation. Contact cause sever pain and may cause eye damage.
Chronic Exposure:
Repeated ingestion may cause tinitus, abnormal bleeding (gastric or retinal), gastric ulcer, weight loss, mental
deterioration, and skin eruptions. May cause kidney and liver damage in susceptible individuals.
Aggravation of Pre-existing Conditions:
Persons with a history of asthma or allergies to aspirin may be at an increased risk upon exposure to this
substance.
4. First Aid Measures
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Call a
physician.
Ingestion:
Induce vomiting immediately as directed by medical personnel. Never give anything by mouth to an unconscious
person. Call a physician.
Skin Contact:
In case of contact, immediately flush skin with plenty of soap and water for at least 15 minutes. Remove
contaminated clothing and shoes. Wash clothing before reuse. Get medical attention if irritation develops or persists. Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally.
Get medical attention immediately.
5. Fire Fighting Measures
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. Minimum explosive dust concentration: 40 g/m3.
Fire Extinguishing Media:
Water spray, foam, or dry chemical.
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
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. 7. Handling and Storage
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 incompatible substances. 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. 8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
- ACGIH Threshold Limit Value (TLV): 5 mg/m3 (TWA)
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 dust/mist respirator 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 dust/mist respirator 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-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.

Environmental Fate:
When released into the soil, this material may leach into groundwater. When released into the soil, this material
may biodegrade to a moderate extent. When released into water, this material is not expected to evaporate
significantly. This material has an estimated bioconcentration factor (BCF) of less than 100. 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:
No information found.
