Indicating Moisture Absorbent

SECTION 2: Hazards identification

Emergency Overview DANGER! CORROSIVE. CAUSES BURNS TO ANY AREA OF CONTACT. HARMFUL IF SWALLOWED OR INHALED. FUMES CAUSE IRRITATION TO EYES AND RESPIRATORY TRACT. WATER REACTIVE. REACTS VIOLENTLY WITH WATER TO GENERATE HEAT AND PHOSPHORIC ACID.

Potential health effects

Phosphorus pentoxide reacts with moisture on body tissue surfaces to form phosphoric acid, which approximates sulfuric acid and hydrochloric acids in corrosive intensity. Inhalation: Inhalation produces damaging effects on the mucous membranes and upper respiratory tract. Symptoms may include irritation of the nose and throat, and labored breathing. May cause lung edema, a medical emergency. Ingestion: Corrosive. Releases heat on contact with moisture and will burn mucous surfaces. Sore throat, abdominal pain, nausea, vomiting, and diarrhea may result. Brown or yellow stains will ne found around the mouth. Suffocation may occur from swelling of the tongue. Aspiratiuon into the lungs can cause chemical pneumonitis. Ingestion of this material has caused human fatalities. Skin Contact: Corrosive. Contact can cause severe irritation, burns, redness, and pain. Burns usually penetrate the skin with sharply defined edges, and heal slowly with the formation of scar tissue. Eye Contact: Corrosive. Fumes and airborne powder cause eye irritation. Contact with substance can cause severe eye burns and permanent damage. Chronic Exposure: Chronic ingestion or inhalation may induce systemic phosphorous poisoning. Liver damage, kidney damage, jaw/tooth abnormalities, blood disorders and cardiovascular effects can result. Aggravation of Pre-existing Conditions: Persons with pre-existing skin disorders or eye problems, jaw/tooth abnormalities, or impaired liver, kidney or respiratory function may be more susceptible to the effects of the substance.
