First Aid Measures

Ingestion

Administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents.

Inhalation

Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.

Skin

Remove contaminated clothing, wash exposed area with copious amounts of water. A physician should examine the area if irritation or pain persists.

Eyes

Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.

Handling and Storage

Storage

Cool, dry location. Tightly sealed container. Keep away from incompatible materials.

Handling

Containers of this material may be hazardous when emptied. Since emptied containers retain product residues (vapor, liquid, and/or solid), all hazard precautions given in the data sheet must be observed.

Hazards Identification

Inhalation

Death normally occurs from sudden cardiorespiratory arrest. Pulmonary edema may develop. Tachypnea may occur secondary to acidosis.

Skin

Skin irritation has been reported after prolonged occupational dermal contact. Skin dryness, irritation, and contact dermatitis have been reported following varying degrees of exposure to detergents.

Eyes

May cause mild eye irritation. Symptoms include stinging, tearing, and redness.

Ingestion

Common initial symptoms are heartburn, followed by nausea and abdominal cramps, vomiting and occasionally diarrhea. Later symptoms include back pain and severe abdominal pain.

Exposure Controls/Personal Protection

Personal Protection

Chemical splash goggles in compliance with OSHA regulations are advised; however, OSHA regulations also permit other type safety glasses. Whre chemical resistant gloves. To prevent repeated or prolonged skin contact, wear impervious clothing and boots.

Respirators

Not required under normal conditions of use.

Exposure Effects

Central nervous system depressant effects, including drowsiness, headache, progressive obtundation and coma have preceded death. Drowsiness is usually delayed approximately 24 hours after ingestion. Meningismus, cerebral edema and hemorrhage, and neuropathies have been reported.

Fire Fighting Measures

Flash Point

93

Fire Fighting

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use agent most appropriate to extinguish fire.

Accidental Release Measures

Small spills/leaks

Small Spill - Absorb liquid on vermiculite, floor absorbent or other absorbent material. Large Spill - Persons not wearing protective equipment should be excluded from area of spill until clean-up has been completed. Stop spill at source, dike area of spill to prevent spreading, pump liquid to salvage tank. Remaining liquid may be taken up on sand, clay, earth, floor absorbent, or other absorbent material and shoveled into containers.

Stability and Reactivity

Stability

Stable.

Incompatibilities

Strong oxidizing agents.

Decomposition

May form: carbon dioxide and carbon monoxide, sulfur oxides, various hydrocarbons.
