Health Hazards Information - Recommended Personal Protective Equipment: Protective goggles, dust
mask; Symptoms Following Exposure: INHALATION: hypochlorous acid fumes cause sever respiratory
tract irritation and pulmonary edema. INGESTION: pain and inflamation of mouth, pharynx,
esophagus, and stomach, erosion of mucous membranes, chiefly of the stomach; vomiting
(hemorrhaging may cause vomitus to resemble coffee ground); circulatory collapse with cold and
clammy skin, cyanosis and shallow respirations; confusion, delirum, coma; edema of pharynx, glottis
and larynx, with stridor and obstruction; perforation of esophagus of stomach, with mediastinitis or
peritonitis. SKIN CONTACT: may cause vesicular eruptions and eczematoic dermatitis; General
Trement for Exposure: INGESTION: swallow immediately milk, egg white, starch paste, milk of
magnesia, aluminum hydroxide gel. Avoid sodium bicarbonate because of the release of carbon dioxide.
Do not use acidic antidotes; cautious gastric lavage with tap water or a 1% solution of sodium
thiosulfate; milk of magnesia (1 oz.) left in the stomach is useful as a mild antacid, adsorbent,
demulcent, and catharic; demulcents, such as starch, egg white, milk, gruel; opiates for the control of
pain. Treat shock vigorously with intravenous fluids. Prompt surgical intervention when indicated, e.g.
tracheotomy, gastrectomy. SKIN: wash with liberal quantities of water and apply a paste of baking
soda; Toxicity by Inhalation (Threshold Limit Value): Not pertinent; Short-Tern Exposure Limits: Not
pertinent; Toxicity by Ingestion: Grade 0; LD,, above 15 g/kg; Late Toxicity: None; Vapor (Gas)
Irritant Characteristics: Not pertinent; Liquid or Solid Irritant Characteristics: Irritates eyes, skin and
mucous membranes; Odor Threshold Not pertinent.
Fire Hazards - Flash Point: Not flammable; Flammable Limits in Air (96): Not flammable; Fire
Extinguishing Agents: Not pertinent; Fire Extinguishing Agents Not To Be Used Not pertinent; Special
HazardF of Combustion Products: Not pertinent; Behavior in Fire: Poisonous gases released upon
exposure to heat; Ignition Temperature: Not flammable; Electrical Hazard Not pertinent; Burning
Rate: Not pertinent.
Chemical Reactivity - Reactivity with Water: No reaction; Reactivity with Common Materials: Can
cause fire on contact with wood or straw, and is corrosive to most metals; Stability During Transport:
The 70 % grade decomposes violently when exposed to heat or direct sunlight. Gives off chlorine and
chlorine monoxide gases above 350 of, which are poisonous gases; Neutralizing Agents for Acids and
