Flush with water for 15 minutes. Get medical attention. Remove contaminated clothing and wash before reuse.
Inhalation
Remove victim from immediate source of exposure to fresh air. If breathing is difficult, administer oxygen if available. If victim is not breathing, administer
CPR. If individual experiences nausea, headache, or dizziness, get immediate medical attention.
Ingestion
Rinse mouth with water. Give water to dilute. Do not induce vomiting. Get immediate medical attention. Never give anything by mouth to a semi-
comatose, comatose, convulsing or unconscious person
Self-protection of the fi rst aider
Use personal protective equipment as required. Avoid contact with skin, eyes or clothing.
Most important symptoms and effects, both acute and delayed
Symptoms
Corrosive. Causes tissue destruction, permanent damage to the cornea, blindness. Causes irritation (possibly severe), burns to the skin. Mists may
cause lung irritation, shortness of breath, fluid in lungs. Ingestion causes nausea, vomiting, diarrhea, corrosion, burns to mouth and esophagus,
abdominal pain, chest pain, shortness of breath, seizures, death.
Indication of any immediate medical attention and special treatment needed
Note to physicians
Product is a corrosive material. Use of gastric lavage or emesis is contraindicated. Possible perforation of stomach or esophagus should be investigated.
Do not give chemical antidotes. Asphyxia from glottal edema may occur. Marked decrease in blood pressure may occur with moist rales, frothy sputum,
and high pulse pressure.
5. Fire-fighting measures
Suitable extinguishing media
Use extinguishing measures that are appropriate to local circumstances and the surrounding environment.
Unsuitable extinguishing media
Do not scatter spilled material with high pressure water streams.
Specific hazards arising from the chemical
If the stock solution container breaks, the solution should be handled with care as it is corrosive. May produce poisonous or irritating gas or fumes. This
material is reactive with many materials. May intensify a fire.
Hazardous combustion products
Nitrogen oxides
Explosion Data
Sensitivity to mechanical impact None
Sensitivity to static discharge None
Protective equipment and precautions for firefighters
As in any fire, wear self-contained breathing apparatus pressure-demand, MSHA/NIOSH (approved or equivalent) and full protective gear. Use water
spray to cool fire exposed containers. Move containers from fire area if you can do it without risk.
6. Accidental release measures
Personal precautions, protective equipment and emergency procedures
Personal precautions
Evacuate nonessential personnel. Ventilate area. Wear appropriate personal protection equipment. Remove sources of ignition.
Environmental precautions
See Section 12 for additional ecological information. Do not flush into surface water or sanitary sewer system. Prevent further leakage or spillage if safe
to do so. Prevent product from entering drains.
Methods for containment
Completely contain spilled material with dikes or sand bags, etc. Stop leak if you can do it without risk.
Methods for cleaning up
Recover as much material as possible into containers for disposal or reuse. Remaining material may be diluted with water and neutralized. Flush spill
area with water. Neutralization products, both solid and liquid, must be recovered for disposal.
