First Aid Measures

Ingestion

Emesis is not indicated due to the irritant nature of these agents. Charcoal - not recommended; it may promote vomiting and make endoscopic evaluation difficult. Dilution: 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). Neutralization - neutralization is not indicated. Although these agents are irritants, and therefore should not produce tissue damage, it is almost impossible to assure that a particular substance under a particular set of circumstances would not cause damage. Therefore, each patient should be examined with the idea that mucous membrane damage might have occurred.

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 soap and water. If symptoms persist, seek medical attention. Launder clothing before reuse.

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. If in a medical facility, sterile saline should be used to irrigate the eyes until the cul de sac is returned to neutrality. Some alkali exposures may require prolonged irrigation.

Handling and Storage

Storage

Keep in a well ventilated area. Keep container tightly closed. Keep awaw from moisture.

Handling

Avoid breathing vapors or mist. Avoid contact. Do not consume food or drink in area.

Hazards Identification

Ingestion

Nausea, vomiting and diarrhea are possible if ingested.

Inhalation

Cough, tachypnea, and wheezing are common after inhalation.

Skin

Redness, swelling and pain may occur.

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

NIOSH/MSHA approved respirator appropriate for exposure of concern.
