IV FIRE AND EXPLOSION HAZARDS DATA
Flash Point (Method Used): N/A Flammable Limits: Upper: N/A Lower: N/A
Extinguishing Media: Water Fog, Dry chemical, Foam, CO2, Water
Special Fire Fighting Procedures: Wear a NIOSH/MSHA approved self-contained breathing apparatus and full protective clothing. Cool containers exposed to fire with water.
Unusual Fire & Explosion Hazard: Oxidizer. Under fire conditions and at high temperatures, highly toxic oxides of nitrogen are emitted.
V HEALTH HAZARD INFORMATION
Exposure Limits in Air (TLV or suggested control figure):
Chemical Name(s) ACGIH OSHA Other
Nuisance Particulates: 10 mg/m3 TWA total dust 15 mg/m3 total dust 5 mg/m3 (respirable)
Nitric Acid: 2 ppm TLV (5 mg/m3) 2 ppm TLV (5 mg/m3)
4 ppm STEL (10 mg/m3) 4 ppm STEL (10 mg/m3)
Effects of Single Over Exposure:
Swallowing: Low toxicity by ingestion. Due to its acidity, this product may burn the mouth, throat and stomach. Acute oral/rat LD50: 3805 mg/kg (hydrous)
Inhalation: Due to its acidity, this product may cause difficulty breathing, chronic bronchitis, chemical pneumonitis, or emphysema. Symptoms may be delayed 4-30 hours.
Skin Contact: Slight skin irritation. Similar rare earth nitrates in solution cause slight irritation to rabbit skin. No absorption data.
Eye Contact: Severe eye irritant. Similar rare earth nitrates in solution cause severe injury to rabbit eyes.
Effects Of Repeated Overexposure:
Nitrates, in general, are not a direct toxicant but are a health hazard because of their conversion to nitrites which in turn cause methemoglobinemia.
Carcinogenicity: This product does not contain any ingredient designated by IARC, NTP, ACGIH or OSHA as a probable human carcinogen.
Significant Laboratory Data with Possible Relevance to Man: No additional data found.
Medical Conditions Aggravated by Overexposure: Skin and respiratory disease; blood disorders.
EMERGENCY AND FIRST AID PROCEDURES:
EYES: In case of contact, immediately flush eyes with plenty of water for at least 15 minutes using an eyewash fountain. Lift upper and lower lids and rinse well under them. Get immediate medical attention, preferably an eye specialist.
SKIN: In case of contact, immediately wash with soap and plenty of water for at least 15 minutes. Remove contaminated clothing and shoes. Thoroughly clean contaminated clothing and shoes before reuse. Get medical attention if irritation develops or persists.
INHALATION: Remove from area of exposure. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. GET IMMEDIATE MEDICAL ATTENTION!!!
INGESTION: GET IMMEDIATE MEDICAL ATTENTION. DO NOT INDUCE VOMITING. If conscious give large quantities of water.
NOTE TO PHYSICIAN: Treat symptomatically. No specific information can be found.
VI REACTIVITY DATA
Stability: Stable
Incompatibility (Material to Avoid): Reducing agents, strong bases, combustible materials, high concentrations of organic matter.
Hazardous Decomposition Products: Toxic oxides of nitrogen are released at decomposition temperatures.
Hazardous Polymerization: Will not occur
VII SPILL OR LEAK PROCEDURES
Steps to Be Taken in Case Material Is Released or Spilled: Wear appropriate protective gear. Sweep up into appropriate container for disposal or recovery. Avoid creating dusting conditions. Ventilate area. Clean spill area with a soda ash slurry and sweep into a drum for disposal.
Waste Disposal Method: In accordance with Local, State and Federal Waste Disposal Regulations.
VIII SPECIAL PROTECTION INFORMATION
Respiratory Protection (Specify Type): Under conditions requiring respiratory protection use a NIOSH/MSHA approved air purifying respirator with particulate filter and acid gas cartridge.
Ventilation: Provide adequate ventilation. Use local exhaust as needed.
Protective Clothing: Work uniform, rubber gloves, rubber apron, rubber boots.
Eye Protection: Chemical workers goggles, DO NOT WEAR CONTACT LENSES.
Other Protective Equipment: Maintain a sink, safety shower and eyewash fountain in the work area. Have oxygen readily available.
IX SPECIAL PRECAUTIONS
Other Handling and Storage Conditions:
♦ Oxidizer. Severe eye and mucous membrane irritant.
♦ Store in tightly closed containers at ambient temperatures.
♦ Do not store near strong reducing agents or organic materials (ie. paper or wood).
♦ Wash thoroughly after handling.
♦ Change contaminated clothing promptly and launder before reuse.
♦ Do not get in eyes, on skin or clothing.
♦ Do not breathe dust, vapor, mist, or gas.
♦ Keep container closed.
♦ Keep away from hear, sparks and open flames.
♦ Empty container may contain hazardous residues.
Dry powder can build static electricity charges when subjected to the friction of conveying, mixing or sliding. To prevent ignition, provide adequate precautions, such as electrical grounding, or inert atmospheres when material is used in the presence of flammable materials.
The above information is believed to be correct, but does not purport to be all inclusive and shall be used only as a guide. ESPI shall not be held liable for any damage resulting from handling or from contact with the above product.
