Hazards and Protection.
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Personal protective equipment should be worn.
Wear positive pressure self-contained breathing apparatus (SCBA).
Avoid inhalation and skin contact. (Non-Specific -- Poisonous Liquid, n.o.s.) Do not touch spilled material; stop leak if you can do so without risk. Use water spray to reduce vapors. Small spills: absorb with sand or other noncombustible absorbent material and place into containers for later disposal. Large spills: dike far ahead of spill for later disposal.
Reacts violently with strong oxidants and acids ;
When heated to decomposition it emits very toxic fumes of hydrogen chloride and nitrogen oxide.
Small Fires: Dry chemical, carbon dioxide or water spray. Large Fires: Dry chemical, carbon dioxide, alcohol-resistant foam or water spray.
Combustible material: may burn but does not ignite readily.
When heated to decomposition, it emits very toxic fumes of nitrogen oxides and chlorides. Polymerizes slowly. (Hazard not specified.)
Fire may produce irritating, corrosive and/or toxic gases.
Tremor, incoordination, ataxia, and convulsions have been seen with exposure to large amounts of related compounds. No data were available to assess the potential effects of exposure to this agent during pregnancy or lactation.
Irritation or burns of the esophagus or gastrointestinal tract could occur if this material is ingested. Nausea and vomiting are to be expected from oral or inhalation exposures.
Dyspnea has been seen.
Ethyl-s is a severe skin irritant and vesicant.
May cause severe eye irritation or damage.
The possible benefit of early removal of some ingested material by cautious gastric lavage must be weighed against potential complications of bleeding or perforation. Activated charcoal activated charcoal binds most toxic agents and can decrease their systemic absorption if administered soon after ingestion. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents.
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.
Time is of the essence - in decontamination; wash exposed area thoroughly with soap and water, then neutralize with a 1/6 m solution of sodium thiosulfate. Corticosteroids and topical antiseptics may be useful. Treat with standard therapy for chemical burns. Treat systematic effects symptomatically.
Time is of the essence - in decontaminating the patient. 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. Topical antibiotics and a mydriatic agent may be used in initial treatment. Contact lenses or lamellar or penetrating keratoplasty may provide improvement of vision in patients who develop delayed keratitis.
