Hazards and Protection.
Do not place or store 1,3-dichloropropene in containers made of aluminum, magnesium, or alloys of these metals. Handle as a flammable liquid. Store at in tightly closed containers in a cool place.
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.
Wear boots, appropriate chemical protective gloves, boots and goggles.
Wear positive pressure self-contained breathing apparatus (SCBA).
Fully encapsulating, vapor protective clothing should be worn for spills and leaks with no fire. ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). All equipment used when handling the product must be grounded. Do not touch or walk through spilled material. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. A vapor suppressing foam may be used to reduce vapors. Absorb with earth, sand or other non-combustible material and transfer to containers (except for Hydrazine). Use clean non-sparking tools to collect absorbed material.
Container may explode in heat of fire and runoff to sewer may be a fire or explosion hazard. Dichloropropenes are a vapor explosion hazard indoors, outdoors, or in sewers. 1,3-dichloropropene can react vigorously with oxidizing materials.
Oxidizing agents, aluminum, halogens, metal salts.
Oxides of carbon, hydrogen chloride.
Some of these materials may react violently with water. SMALL FIRES: Dry chemical, carbon dioxide, water spray or alcohol-resistant foam. LARGE FIRES: Water spray, fog or alcohol-resistant foam. Move containers from fire area if you can do it without risk. Dike fire control water for later disposal; do not scatter the material. Do not get water inside containers. FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. For massive fire, use unmanned hose holders or monitor nozzles; if this is impossible, withdraw from area and let fire burn.
May be ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. May polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
Fire will produce irritating, corrosive and/or toxic gases.
May cause toxic effects.
Ards has been reported after ingestion. Animals exposed to 2700 ppm developed severe lung injury.
Necrosis and edema were present when the agent was confined to rabbit skin, but were much reduced when the product was allowed to evaporate.
Prompt washing decreased the degree of irritation. Nasal irritation also occurred at concentrations greater than 1000 ppm.
Administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents. Monitor liver and kidney function. Elevations may not be seen for several days. Respiratory support may be indicated in significant exposures. Monitor for pulmonary edema. Hypotension: infuse 10 to 20 ml/kg isotonic fluid, place in trendelenburg position. If hypotension persists, administer dopamine (5 to 20 mcg/kg/min) or norepinephrine (0.1 To 0.2 Mcg/kg/min), titrate to desired response.
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult.
Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists.
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.
