VI. EFFECTS OF OVEREXPOSURE
PERMISSIBLE No permissible exposure limits have been established by OSHA.
ACUTE
INHALATION Inhalation of this material is irritating to the nose, mouth, throat, and lungs. It may also cause burns to the respiratory tract with the production of lung edema which
can result in shortness of breath, wheezing, choking, chest pain, and impairment of lung function. Inhalation of high concentrations can result in permanent lung
damage. Chronic (repeated) inhalation exposure may cause impairment of lung function and permanent lung damage.
EYE/SKIN Severe irritation and/or burns can occur following eye exposure. Contact may cause impairment of vision and corneal damage. Contact with skin may cause severe
irritation, burns, or tissue destruction.
INGESTION Irritation and/or burns can occur to the entire gastrointestinal tract, including the stomach and intestines, characterized by nausea, vomiting, diarrhea, abdominal
pain, bleeding, and/or tissue ulceration.
CHRONIC There are no known or reported effects from chronic exposure.
VII. EMERGENCY AND FIRST AID PROCEDURES
INHALATION Remove to fresh air. Give artificial respiration, preferably mouth-to-mouth. If breathing is difficult, give oxygen. Seek medical attention immediately.
EYE CONTACT Immediately flush with large amounts of water for fifteen (15) minutes, rinsing eye thoroughly. Get medical attention.
SKIN CONTACT Wash with plenty of soap and water for fifteen (15) minutes. Remove contaminated clothing and wash before reuse. If skin irritation occurs, get medical attention.
INGESTION If conscious, drink a large quantity of water and common vegetable oil. Do NOT induce vomiting. Take immediately to hospital. Avoid alcohol.
If unconscious, or in convulsions, seek medical attention immediately. Do not give anything by mouth to an unconscious person.
VIII. REACTIVITY DATA
STABILITY Unstable.
CONDITIONS TO AVOID Any form of contamination or excessive heat above 177° C.
INCOMPATIBILITY Acids, combustible materials, organics, reducing agents, flammables, beverages, compounds containing nitrogen, dry
powder fire extinguishers (containing mono-ammonium phosphate).
HAZARDOUS DECOMPOSITION PRODUCTS Acids or ammonia contamination will release toxic gas. Excessive heat may cause decomposition and release chlorine gas.
IX. SPILL AND LEAK PROCEDURE
USE EXTREME CAUTION IN HANDLING SPILLED MATERIAL. CONTAMINATION WITH ORGANIC OR COMBUSTIBLE MATERIAL MAY CAUSE FIRE OR VIOLENT DECOMPOSITION. IF FIRE OR
DECOMPOSITION OCCURS IN AREA OF SPILL, IMMEDIATELY DOUSE WITH PLENTY OF WATER. OTHERWISE, SWEEP UP ALL VISIBLE MATERIAL USING A CLEAN, DRY SHOVEL AND BROOM
AND DISSOLVE MATERIAL IN WATER. CARE MUST BE TAKEN WHEN USING OR DISPOSING OF CHEMICAL MATERIALS TO PREVENT ENVIRONMENTAL CONTAMINATION. IT IS YOUR DUTY
TO DISPOSE OF THE CHEMICAL MATERIALS AND/OR THEIR CONTAINERS IN ACCORDANCE WITH THE CLEAN AIR ACT, THE CLEAN WATER ACT AND RCRA REGULATIONS.
X. SPECIAL PROTECTION INFORMATION
RESPIRATORY PROTECTION If conditions are dusty, use NIOSH respirator with acid gas cartridge and dust pre-filter.
VENTILATION Not required unless dusty conditions are encountered. Store and use in a well-ventilated area.
