Emergency Overview
DANGER! CORROSIVE. CAUSES BURNS TO ANY AREA OF CONTACT. MAY BE FATAL IF
SWALLOWED OR INHALED.
SAF-T-DATA(tm) Ratings (Provided here for your convenience)
Health Rating: 4 - Extreme (Poison)
Flammability Rating: 1 - Slight
Reactivity Rating: 1 - Slight
Contact Rating: 4 - Extreme (Corrosive)
Lab Protective Equip: GOGGLES & SHIELD; LAB COAT & APRON; VENT HOOD; PROPER
GLOVES
Storage Color Code: White (Corrosive)
Potential Health Effects
Inhalation:
Corrosive. Extremely destructive to tissues of the mucous membranes and
upper respiratory tract. Symptoms may include burning sensation, coughing,
wheezing, laryngitis, shortness of breath, headache, nausea and vomiting.
Inhalation may be fatal as a result of spasm inflammation and edema of the
larynx and bronchi, chemical pneumonitis and pulmonary edema.
Ingestion:
Corrosive. Swallowing can cause severe burns of the mouth, throat, and
stomach, leading to death. Can cause sore throat, vomiting, diarrhea.
Skin Contact:
Corrosive. Symptoms of redness, pain, and severe burn can occur.
Eye Contact:
Corrosive. Contact can cause blurred vision, redness, pain and severe tissue
burns.
Chronic Exposure:
Liver and kidney dysfunctions have been reported.
Aggravation of Pre-existing Conditions:
Persons with pre-existing lung disease may be more susceptible to the
effects of this substance.
First Aid Measures
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Call a physician immediately.
Ingestion:
DO NOT INDUCE VOMITING. Give large quantities of water. Never give anything
by mouth to an unconscious person. Call a physician immediately.
Skin Contact:
Immediately flush skin with plenty of water for at least 15 minutes while
removing contaminated clothing and shoes. Call a physician, immediately.
Wash clothing before reuse.
Eye Contact:
Immediately flush eyes with gentle but large stream of water for at least 15
minutes, lifting lower and upper eyelids occasionally. Call a physician
immediately.
Fire Fighting Measures
Fire:
Flash point: 126C (259F) CC
Flammable limits in air % by volume:
lel: 8
Explosion:
Above flash point, vapor-air mixtures are explosive within flammable limits
noted above. Fine dust dispersed in air in sufficient concentrations, and in
the presence of an ignition source is a potential dust explosion hazard.
Fire Extinguishing Media:
Water spray, dry chemical, alcohol foam, or carbon dioxide.
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.
Accidental Release Measures
Remove all sources of ignition. Ventilate area of leak or spill. Wear
appropriate personal protective equipment as specified in Section 8. Keep
unnecessary and unprotected personnel away.
Spills: Clean up spills in a manner that does not disperse dust into the
air. Use non-sparking tools and equipment. Pick up spill for recovery or
disposal and place in a closed container.
If material comes in contact with water, neutralize liquid with alkaline
material (soda ash, slaked lime) then absorb with an inert materail (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.
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. Storage in metal containers is not recommended, since material is
corrosive to metals. 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.
