First Aid Measures

Ingestion

Immediately dilute with 4 to 8 ounces (120 to 240 ml) of milk or water (not to exceed 4 ounces/120 ml in a child). Spontaneous vomiting frequently occurs following ingestion. If spontaneous vomiting does not occur then significant ingestion is unlikely. Administration of activated charcoal is unnecessary. Observe patients with ingestion carefully for the possible development of esophageal or gastrointestinal tract irritation or burns. If signs or symptoms of esophageal irritation or burns are present, consider endoscopy to determine the extent of injury. Patient should be evaluated for burns to the mouth and esophagus following ingestion of low phosphate detergents which are generally more alkaline.

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

Keep in a cool, dry location in a tightly sealed container.

Handling

Good personal hygiene should always be followed.

Hazards Identification

Ingestion

Nausea, vomiting, and diarrhea are common. Oral, pharyngeal and esophageal burns may occur following ingestion of low phosphate detergents which are generally more alkaline. Colitis, esophageal stricture, and irritation of mucous membranes have also been reported.

Inhalation

Occupational asthma has been reported. Aspiration may result in upper airway edema and significant respiratory distress. Difficulty in breathing has been described in animals inhaling high concentrations of anionic surfactants.

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

Irritant.

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

Contain the spill, collect on absorbent material and discard as dictated by Federal, state and local regulations that may apply. Flush area thoroughly with water.

Stability and Reactivity

Stability

No data.

Incompatibilities

Strong oxidizing agents.
