California Freight Safety Manual and IIPP <br /> 4. Lubricants <br /> a. Insoluble Oils and Greases <br /> Characteristics: Commonly known as lubricating oils or greases, these oils are generally <br /> petroleum based hydrocarbon mixtures that contain no water. Appearance may range <br /> from clear light brown liquids to dark brown greases. Oils can be fire hazards because <br /> they are combustible. Examples of common oils and greases are multi weight motor oil, <br /> gear lubricating oils and cutting oils used in some machining operations. <br /> Health Hazards: Petroleum based oils and greases are generally of low toxicity. Oil mists <br /> and vapors can be generated from sawing and metal forming operations. Inhalation of <br /> these mists may cause mild irritation of the nose and throat. The mist may also irritate <br /> the eyes. Overexposure by inhalation, although rare, can cause headaches, nausea, or <br /> dizziness. The most common exposure to oils and greases is through the skin. Excessive <br /> or prolonged exposure of the skin to oils, especially used, dirty, or contaminated oils, <br /> may cause chronic skin conditions such as contact dermatitis. Ingestion of these <br /> substances may be harmful, depending on the purity of the oil, and the amount <br /> ingested. <br /> Personal Protective Equipment/Handling: Under most circumstances, inhalation <br /> overexposure to oil products is not common. If no local exhaust ventilation is available <br /> in operations that generate oil mist, a respirator with an organic vapor/particulate <br /> cartridge should be utilized. There is no substitute for safe work practices and good <br /> personal hygiene. Any practical way to reduce time and frequency of skin exposure to <br /> oils is recommended. Mild waterless hand cleaners are helpful in removing oil. Never <br /> use solvents to clean the skin. This will only increase the risk of unusual skin disorders <br /> and/or dermatitis. Oil resistant protective gloves should be used whenever feasible, and <br /> skin cream should be applied after washing to prevent drying. Safety glasses or goggles <br /> should be worn to prevent oil from splashing into the eyes. <br /> Emergency/Special: Lubricating oils, like any other chemicals, should be handled with <br /> care. In the event of eye contact, flush with water for 15 minutes, and then seek <br /> medical attention. In case of accidental ingestion, do not induce vomiting, give milk or <br /> water, and seek medical attention. Any areas of skin contact should be washed <br /> thoroughly with mild soap and lukewarm water or waterless hand cleaner to reduce the <br /> risk of skin disorders. <br /> b. Aerosol Spray Lubricants <br /> Characteristics: Aerosol spray lubricants, unlike other oil based lubricants, generally <br /> contain a high percentage of halogenated solvents such as 1,1,1 trichloroethane. <br /> Examples of spray lubricants include gear oil and silicone spray. <br /> Revised January 1,2019 Page 80 <br />
