Safety # 5Fire Safety and Hazmat Series of Safety Presentations include: 1 = Facility 2 = Shop Equipment + Tools 3 = Vehicle Lifting 4 = Personal Protective Equipment 5 = Fire Safety + Hazmat
FIRE BLANKETS • Fire blankets are required to be available in the shop areas. FIGURE 1-13 A treated wool blanket is kept in this easy-to-open wall-mounted holder and should be placed in a centralized location in the shop.
Fire Hazards and Prevention • Fuels used in modern ICE are highly volatile and require proper handling and storage. • Diesel fuel is not as refined and contain active micro-organisms that can cause infections. • Cleaning solvents and shop rags must be stored and handled properly to prevent fires.
Classes of Fires • Class “A” fires • Ordinary combustibles such as wood, paper, and plastics. • Class “B” fires • Flammable liquids such as gasoline, oil, grease, and paint. • Class “C” fires • Electrical equipment such as electric motors, wiring, and fuse boxes. • Class “D” fires • Combustible metals such as aluminum, magnesium, and potassium.
Fire Safety • Make sure fire extinguishers are accessible and maintained. • Do not fight a fire that is too large to control. Get out of the building.
FIRE EXTINGUISHERS FIGURE 1-11 A typical fire extinguisher designed to be used on class A,B, or C fires. FIGURE 1-12 A CO2 fire extinguisher being used on a fire set in an open steel drum during a demonstration at a fire department training center.
FIRE EXTINGUISHERS • There are four classes of fire extinguishers. Each class should be used on specific fires only: • Class A is designed for use on general combustibles, such as cloth, paper, and wood. • Class B is designed for use on flammable liquids and greases, including gasoline, oil, thinners, and solvents. • Class C is used only on electrical fires. • Class D is effective only on combustible metals such as powdered aluminum, sodium, or magnesium.

Fire Safety(continued) • Store oily rags in a covered container. • Store gasoline safely in an approved container.
Gasoline is: • Highly flammable • Volatile – heavier than air (fumes to ground) • Needs oxygen to burn • MUST be stored in approved container • Container should be “red” in color • Never smoke around open containers • Rags soaked in gas should be taken outside to dry before you dispose of them • Provide proper ventilation

KNOWLEDGE CHECK Rules to remember when using gasoline include each of the following EXCEPT: • Use quick dry to absorb any spills • Store gasoline in approved containers • Keep gasoline away from sources of heat • Never use gasoline as a cleaning solvent • A = Don’t use quick dry to absorb fuel – the quick dry may become flammable.

Technician B says the MSDS contains information about health and safety concerns associated with chemicals used in the shop. Who is correct? • Technician A • Technician B • Both Technicians A and B • Neither Technician A nor B • C = Both Technicians
Breathing Safety Take precautions against breathing: • Paint fumes. • Asbestos. • Cleaning chemicals. • Grinding dust. • Vehicle exhaust.
Asbestos • Identified as a health hazard • Can lead to cancer – mesothelioma • When breathed, fibers can cause scarring of the lung tissue • All asbestos waste must be disposed of in accordance with OSHA and EPA regulations
ASBESTOS OSHA STANDARDS & REGULATIONS • The Occupational Safety and Health Administration (OSHA) has established three levels of asbestos exposure. • Any vehicle service establishment that does either brake or clutch work must limit employee exposure to asbestos to less than 0.2 fibers per cubic centimeter (cc) as determined by an air sample. • The federal Environmental Protection Agency (EPA) has established procedures for the removal and disposal of asbestos. • The EPA procedures require that products containing asbestos be “wetted” to prevent the asbestos fibers from becoming airborne.
ASBESTOS HANDLING GUIDELINES • The air in the shop area can be tested by a testing laboratory, but this can be expensive. • Tests have determined that asbestos levels can easily be kept below the recommended levels by using a solvent or a special vacuum. • HEPA Vacuum • Solvent Spray • Disposal of Brake Dust and Brake Shoes FIGURE 2-2 All brakes should be moistened with water or solvent to help prevent brake dust from becoming airborne.
THE DANGERS OF EXPOSURE TO ASBESTOS • Asbestos exposure can cause scar tissue to form in the lungs. • This condition is called asbestosis. It gradually causes increasing shortness of breath, and the scarring to the lungs is permanent.
KNOWLEDGE CHECK Technician A says that asbestos is found in some brake pad materials. Technician B says that asbestos is found in some clutch materials. Who is correct? • Technician A only • Technician B only • Both Technicians A and B • Neither Technician A nor B • C = Both Technicians

WHAT EVERY TECHNICIAN SHOULD KNOW FIGURE 2-11 The Environmental Protection Agency (EPA) Hazardous Materials Identification Guide is a standardized listing of the hazards and the protective equipment needed.
MATERIAL SAFETY DATA SHEETS • All hazardous materials must be properly labeled, and information about each hazardous material must be posted on Material Safety Data Sheets (MSDSs) available from the manufacturer. FIGURE 2-1 Material Safety Data Sheets (MSDSs) should be readily available for use by anyone in the area who may come into contact with hazardous materials.
KNOWLEDGE CHECK Where can complete EPA lists of hazardous wastes be found? • Code of Federal Regulations • Gasoline is ____________ • highly volatile • highly flammable • dangerous, especially in vapor form • All of the above • D – All of the above
HAZARDOUS WASTE • Hazardous waste materials are chemicals, or components, that the shop no longer needs that pose a danger to the environment and people if they are disposed of in ordinary garbage cans or sewers. • The EPA considers waste hazardous if it is included on the EPA list of hazardous materials, or it has one or more of the following characteristics. • Reactive • Corrosive • Toxic • Ignitable • Radioactive
OCCUPATIONAL SAFETY AND HEALTH ACT • The U.S Congress passed the Occupational Safety and Health Act in 1970. • Since approximately 25% of workers are exposed to health and safety hazards on the job, the standards are necessary to monitor, control, and educate workers regarding health and safety in the workplace.
RESOURCE CONSERVATION AND RECOVERY ACT (RCRA) • Federal and state laws control the disposal of hazardous waste materials. • The Resource Conservation and Recovery Act (RCRA) states that hazardous material users are responsible for hazardous materials from the time they become a waste until the proper waste disposal is completed.
RESOURCE CONSERVATION AND RECOVERY ACT (RCRA) • The RCRA controls these types of automotive waste: • Paint and body repair products waste • Solvents for parts and equipment cleaning • Batteries and battery acid • Mild acids used for metal cleaning and preparation • Waste oil, and engine coolants or antifreeze • Air-conditioning refrigerants and oils • Engine oil filters • The right-to-know laws state that employees have a right to know when the materials they use at work are hazardous. • The right-to-know laws started with the Hazard Communication Standard published by the Occupational Safety and Health Administration (OSHA) in 1983.
