7 Maintaining a Safe and Orderly Shop
Arrange machinery and equipment to permit safe, efficient work practices and ease in cleaning Stack or store materials and supplies safely in proper places Store tools safely in cabinets, racks, or other suitable devices Keep working areas and work benches clear and free of debris and other hazards

12 Types of Fire Extinguishers
Pressurized Water- used on Class A fires Carbon Dioxide- used on Class B and C fires Dry Chemical- used on Class B, C, D fires Foam- used on Class A , B fires


14 Fire Prevention Never strike sparks in a room or area where flammable liquids are used or stored Use only approved safety cans for storage of flammable liquids and label them properly Do not fill a hot or running engine with gas Use a commercial nonflammable cleaner for cleaning tools and parts

15 Fire Prevention Change any oil or gasoline soaked clothes immediately

23 Batteries Handle batteries with care and use a battery strap or carrier Always hold batter upright and set securely so there is no danger of spilling acid Never smoke, use and open flame, or cause a spark on battery terminals When mixing battery solutions, always pour acid into water If acid splashes on you, immediately flush with cold water
