California Freight Safety Manual and IIPP <br /> Health Hazards: Refer to category 1A (Halogenated Solvents) for overall health hazards <br /> of aerosol spray lubricants. <br /> Additional Information: Most of the aerosol sprays are usually extremely flammable <br /> because of the propellants used (butane, propane, etc.). Phosgene gas, an extremely <br /> toxic gas, may be generated as a decomposition product of combustion if the spray <br /> lubricants come in contact with a flame (e.g., lighted cigarette, or welding operations) or <br /> a very hot metal. Phosgene gas can cause severe irritation to the nose, throat and eyes, <br /> even at extremely low concentrations. Exposure to moderate concentrations can cause <br /> a delayed onset of pulmonary edema (fluid in the lungs) that may progress to <br /> pneumonia. <br /> Personal Protective Equipment/Handling: All solvent-based materials should be used in <br /> well-ventilated areas. Use a respirator if spraying moderate concentrations to avoid <br /> overexposure. Air-supplying respirators should be used if high concentrations are <br /> present. Avoid contact with the skin to reduce the risk of irritation and/or dermatitis. <br /> Use chemically resistant gloves for prolonged or repeated contact. Always wear safety <br /> glasses or goggles to prevent eye contact with the aerosol spray. <br /> Emergency/Special: In the event of eye contact, flush with water for 15 minutes. Wash <br /> skin with soap and water. If ingested, do not induce vomiting and seek immediate <br /> medical attention. In case of overexposure by inhalation, remove the person to fresh <br /> air, seek medical attention, and apply artificial respiration if necessary. Containers <br /> should be stored in a clean, dry area. Avoid storing at temperatures above 80 degrees F. <br /> to reduce the risk of the aerosol containers bursting or exploding. <br /> 5. Compressed Gases <br /> Characteristics: These gases are typically stored in cylinders. The gases are frequently <br /> stored in a liquid state and are utilized in a variety of applications such as welding <br /> (acetylene), oxidation (oxygen), fuel delivery (propane, butane), cryogenics (liquid <br /> helium, oxygen, nitrogen). <br /> Health Hazards: Depending on the specific gas contained within the cylinder, the <br /> associated hazards exhibited can be similar to those of the substances described in <br /> previous categories. For example, anhydrous ammonia gas falls within the <br /> corrosive/caustic hazard category. Asphyxiation is the primary hazard associated with <br /> compressed gases since they can displace oxygen if there is a sudden and quick release, <br /> particularly in confined work areas. Compressed gases, either in liquid or vapor form, <br /> are cryogenic and will cause severe frostbite and burns if allowed to contact the skin. <br /> Personal Protective Equipment/Handling: Self-contained or airline breathing apparatus <br /> should be worn in oxygen-deficient atmospheres. General ventilation is usually <br /> adequate to maintain sufficient oxygen level. Avoid skin contact with liquid gases. <br /> Revised January 1,2019 Page 81 <br />
