Hazard Flammable gas. May form explosive mixtures with air. Contains gas under pressure; may explode if heated. May displace oxygen and cause rapid suffocation. Harmful if inhaled. Causes severe skin burns and eye damage. Very toxic to aquatic life.

Very hazardous in case of skin contact, of eye contact, of ingestion. Non-corrosive to the eyes. Non-corrosive for lungs. Liquid or spray mist may produce tissue damage particularly on mucous membranes of eyes, mouth and respiratory tract. Skin contact may produce burns. Inhalation of the spray mist may produce severe irritation of respiratory tract, characterized by coughing, choking, or shortness of breath. Severe over-exposure can result in death. Eyes redness, watering, and itching. Skin inflammation is characterized by itching, scaling, reddening, or, occasionally, blistering.

Small spill: Dilute with water and mop up or absorb with an inert dry material and place in an appropriate waste disposal container. If necessary . Neutralize the residue with a dilute solution of acetic acid. Large Spill: Corrosive liquid. Poisonous liquid. Stop leak if without risk. Absorb with DRY earth, sand or other non-combustible material. Do not get water inside container. Do not touch spilled material. Use water spray curtain to divert vapor drift. Use water spray to reduce vapors. Prevent entry into sewers, basements or confined areas; dike if needed. Call for assistance on disposal. Neutralize the residue with a dilute solution of acetic acid. Be careful that the product is not present at a concentration level above TLV.

Small Spill: Use appropriate tools to put the spilled solid in a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and dispose of according to local and regional authority requirements. Large Spill: Use a shovel to put the material into a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and allow to evacuate through the sanitary system.

Recommended Control Measure

Appropriate engineering controls: Use only with adequate ventilation. Use process enclosures, local ex ventilation or other engineering controls to keep worker exposure to airborne contaminants below any recommended or statutory limits. The engineering controls also need to keep gas, vapor or dust concentra below any lower explosive limits. Use explosion-proof ventilation equipment. Protective measures: Put on appropriate personal protective equipment (see Section 8). Contains gas u pressure. Do not get in eyes or on skin or clothing. Do not breathe gas. Avoid release to the environment. with adequate ventilation. Wear appropriate respirator when ventilation is inadequate. Do not enter storag and confined spaces unless adequately ventilated. Store and use away from heat, sparks, open flame or ignition source. Empty containers retain product residue and can be hazardous. Do not puncture or incine container. Use equipment rated for cylinder pressure. Close valve after each use and when empty. Protec from physical damage; do not drag, roll, slide, or drop. Use a suitable hand truck for cylinder movement.
