Potential Health Effects ----------------------------------
Inhalation:
Inhalation of dust or vapor may cause irritation of the nose and throat. Coughing, sneezing, and burning of the throat may be experienced. Can cause allergic respiratory reactions. Ingestion:
Corrosive. Toxic. Swallowing can cause sore throat, abdominal pain, and vomiting. May cause burns to the digestive tract. Skin Contact:
Corrosive. May not cause immediate burning of the skin, but prolonged contact with moist skin cause reddening and blistering or burns. Eye Contact:
Corrosive. Dust or vapor cause burns or irritation of the eyes with swelling. Sensitivity to light and double vision may occur. Chronic Exposure:
Repeated inhalation may cause chronic bronchitis of the asthmatic type. Repeated skin contact may lead to dermatitis or sensitization. Aggravation of Pre-existing Conditions: No information found.
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.
Skin Contact:
In case of contact, immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Call a physician immediately. 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:
Flash point: 102C (216F) CC
Autoignition temperature: 477C (891F) Flammable limits in air % by volume: lel: 1.4; uel: 7.1 Explosion:
Above flash point, vapor-air mixtures are explosive within flammable limits noted above.
Fire Extinguishing Media:
Alcohol foam, carbon dioxide. DO NOT USE dry chemical, multipurpose dry chemical, or loaded stream media because of explosion potential due to reactivity of basic compounds in these extinguishing media. 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. Evacuate area of all unnecessary personnel. US Regulations (CERCLA) require reporting spills and releases to soil, water and air in excess of reportable quantities.
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. Do not reuse container. 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. Avoid dust formation and control ignition sources. Employ grounding, venting and explosion relief provisions in accord with accepted engineering practices in any process capable of generating dust and/or static electricity. Empty only into inert or non-flammable atmosphere. Emptying contents into a non-inert atmosphere where flammable vapors may be present could cause a flash fire or explosion due to electrostatic discharge.
