Intravenous lines should be established immediately in all cases where there is evidence of circulatory compromise. <br /> 4.Strong acids produce a coagulation necrosis characterized by formation of a coagulum (eschar) as a result of the <br />desiccating action of the acid on proteins in specific tissues. <br /> INGESTION: <br /> 1.Immediate dilution (milk or water) within 30 minutes post-ingestion is recommended. <br /> 2.Do not attempt to neutralize the acid since exothermic reaction may extend the corrosive injury. <br /> 3.Be careful to avoid further vomiting since re-exposure of the mucosa to the acid is harmful. Limit fluids to one or <br />two glasses in an adult. <br /> 4.Charcoal has no place in acid management. <br /> 5.Some authors suggest the use of lavage within 1 hour of ingestion. <br /> SKIN: <br /> 1.Skin lesions require copious saline irrigation. Treat chemical burns as thermal burns with non-adherent gauze and <br />wrapping. <br /> 2.Deep second-degree burns may benefit from topical silver sulfadiazine. <br /> EYE: <br /> 1.Eye injuries require retraction of the eyelids to ensure thorough irrigation of the conjunctival cul-de-sacs. Irrigation <br />should last at least 20-30 minutes. Do not use neutralizing agents or any other additives. Several liters of saline are <br />required. <br /> 2.Cycloplegic drops (1% cyclopentolate for short-term use or 5% homatropine for longer term use), antibiotic drops, <br />vasoconstrictive agents, or artificial tears may be indicated dependent on the severity of the injury. <br /> 3.Steroid eye drops should only be administered with the approval of a consulting ophthalmologist. <br />Section 5 - Fire-Fighting Measures <br />Flash Point: Nonflammable <br />Autoignition Temperature: Not applicable <br />LEL: Not applicable <br />UEL: Not applicable <br />Extinguishing Media: Water spray or fog; foam; <br />Bromochlorodifluoromethane (BCF) (where regulations permit); Dry agent; Carbon <br />dioxide. <br />General Fire Hazards/Hazardous Combustion Products: Noncombustible liquid. Will <br />not burn, but heat produces highly toxic fumes/vapors. <br /> Heating may cause expansion or decomposition leading to violent rupture of containers. <br /> Decomposes on heating and produces toxic fumes of hydrogen chloride. Decomposition <br />may produce toxic fumes of chlorine. <br /> Reacts with metals producing flammable/explosive hydrogen gas. Contact with moisture or water may generate <br />heat causing ignition. Reacts vigorously with alkalis. Moderate fire hazard when in contact with reducing agents. <br />Fire Incompatibility: Reacts with metals producing flammable/explosive hydrogen gas. <br /> Avoid reactions with metals, metal oxides, hydroxides, amines, carbonates, alkaline materials, acetic anhydride, <br />cyanides, sulphides, sulphites, phosphides, acetylides, borides, carbides, silicides, vinyl acetate, formaldehyde and <br />potassium permanganate, unsaturated organics, metal acetylides, sulphuric acid. <br /> Note: Compatibility with plastics should be confirmed prior to use. <br />Fire-Fighting Instructions: Contact fire department and tell them location and nature of hazard. <br /> Wear full body protective clothing with breathing apparatus. Prevent, by any means available, spillage from entering <br />drains or waterways. Consider evacuation. Cool fire-exposed containers with water spray from a protected location. <br />If safe to do so, remove containers from path of fire. Equipment should be thoroughly decontaminated after use. <br /> Water spray or fog may be used to disperse vapor. Do not approach cylinders suspected to be hot. If safe to do so, <br />stop flow of gas. <br />Section 6 - Accidental Release Measures <br />Small Spills: DO NOT touch the spill material. Clean up all spills immediately. Wear fully protective <br />PVC clothing and breathing apparatus. Contain and absorb spill with sand, earth, inert material or <br />vermiculite. Use soda ash or slaked lime to neutralize. Collect residues and place in labeled plastic <br />containers with vented lids. Clear area of personnel and move upwind. Avoid breathing vapors and <br />contact with skin and eyes. Do not exert excessive pressure on valve; do not attempt to operate <br />damaged valve. Water spray or fog may be used to disperse vapor. <br />Large Spills: Contact fire department and tell them location and nature of hazard. Clear area of personnel and move <br />upwind. Wear full body protective clothing with breathing apparatus. Prevent, by any means available, spillage from <br />entering drains or waterways. Consider evacuation. Stop leak if safe to do so. Remove leaking cylinders to a safe <br />place if possible. Release pressure under safe, controlled conditions by opening the valve. Do not exert excessive <br />pressure on valve; do not attempt to operate damaged valve. Shut off all possible sources of ignition and increase <br />ventilation. Water spray or fog may be used to disperse vapor. Use soda ash or slaked lime to neutralize. <br /> Collect and seal in labeled drums for disposal. Wash spill area with large quantities of water.
