Consult a physician. Show this safety data sheet to the doctor in attendance.If inhaled
Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention. See Notes.In case of skin contact
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .In case of eye contact
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.If swallowed
Rinse mouth. Do NOT induce vomiting. Refer for medical attention .4.2 Most important symptoms/effects, acute and delayed
Inhalation of vapors or mist causes burning sensation of nose and throat, and lung irritation with coughing; prolonged or excessive exposure could cause vomiting and severe coughing. Ingestion causes blistering and burns of mouth and stomach. Contact with eyes or skin causes blistering and burns. (USCG, 1999)
Excerpt from ERG Guide 140 [Oxidizers]: Inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or death. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution. (ERG, 2016)4.3 Indication of immediate medical attention and special treatment needed, if necessary
no data available5.Fire-fighting measures 5.1 Extinguishing media Suitable extinguishing media
COMBAT FIRES FROM SAFE DISTANCE OR PROTECTED LOCATION. FLOOD DISCHARGE AREA WITH WATER. COOL EXPOSED CONTAINERS WITH WATER. /AQUEOUS SOLN/5.2 Specific hazards arising from the chemical
Behavior in Fire: Above 160°C (160°C) will react with combustible material and increase intensity of fire. Containers may explode. (USCG, 1999)
Excerpt from ERG Guide 140 [Oxidizers]: These substances will accelerate burning when involved in a fire. Some may decompose explosively when heated or involved in a fire. May explode from heat or contamination. Some will react explosively with hydrocarbons (fuels). May ignite combustibles (wood, paper, oil, clothing, etc.). Containers may explode when heated. Runoff may create fire or explosion hazard. (ERG, 2016)5.3 Special protective actions for fire-fighters
Wear self-contained breathing apparatus for firefighting if necessary.6.Accidental release measures 6.1 Personal precautions, protective equipment and emergency procedures
Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8.6.2 Environmental precautions
Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Do NOT absorb in saw-dust or other combustible absorbents. Absorb liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Cautiously neutralize remainder. Do NOT wash away into sewer.6.3 Methods and materials for containment and cleaning up
NEUTRALIZING AGENTS FOR ACIDS & CAUSTICS: FLUSH WITH WATER & RINSE WITH DILUTE SODIUM BICARBONATE OR SODA ASH SOLUTION.7.Handling and storage 7.1 Precautions for safe handling
Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Avoid exposure - obtain special instructions before use.Provide appropriate exhaust ventilation at places where dust is formed. For precautions see section 220.127.116.11 Conditions for safe storage, including any incompatibilities
