Section 03 - Hazard Identification
Inhalation...................鈥︹?︹?︹??.鈥?.... Vapour or mist can cause irritation to nose, throat, and upper respiratory
tract. Symptoms include: coughing, choking, and bleeding of the nose
and gums. Severe exposure can result in pulmonary edema and
corrosion of tissues in the nose and throat.
Skin Contact / Absorption鈥︹??.鈥?.... Contact may produce severe irritation or corrosive skin damage,
depending upon length of contact and amount of acid. Effects range from
dermititis, photo sensitization, redness, swelling, pain, permanent
scarring, to death.
Eye Contact................鈥︹?︹?︹??.鈥?.... Low concentrations of vapour or mist can be irritating, causing redness.
Concentrated vapour, mist or splashed liquid can cause severe irritation,
burns and permanent blindness.
Ingestion.....................鈥︹?︹?︹?︹?︹??. Causes severe burns of the mouth, esophagus, and stomach, with
consequent pain, nausea, vomiting, diarrhea, circulatory collapse, and
possibly death.
Exposure Limits鈥︹?︹?︹?︹?︹?︹?︹??... ACGIH/PEL= 5ppm (hydrochloric acid)
Section 04 - First Aid Measures
Inhalation....................鈥︹?︹?︹?︹?︹??.. Remove victim to fresh air. Give artificial respiration only if breathing has
stopped. If breathing is difficult, give oxygen. Seek immediate medical
attention.
Skin Contact / Absorption鈥︹?︹?︹??.. Remove contaminated clothing. Wash affected area with lukewarm water
for 20-30 minutes. Seek medical attention immediately.
Eye Contact..................鈥︹?︹?︹?︹??.... Flush immediately with lukewarm water for at least 20 minutes. Forcibly
hold eyelids apart to ensure complete irrigation of eye tissue. Seek
immediate medical attention.
Ingestion......................鈥︹?︹?︹?︹?︹??. Do not induce vomiting. If vomiting occurs, lean victim forward to prevent
breathing in vomitus. Rinse mouth out with water. If the victim can
swallow, give 1 cup of water or milk to dilute. If vomiting occurs, rinse the
mouth out and give another cup of water. Do not give anything by mouth
to an unconscious or convulsing person. Seek immediate medical
attention.
