Chapter 5 Auto Shop Safety 65 Copyright Goodheart-Willcox Co., Inc. Summary • An auto shop can be a safe and enjoyable place to work. However, if basic safety rules are not followed, an auto shop can be very dangerous. • The shop repair area includes the locations in which repair operations are performed. • The toolroom is typically adjacent to the main shop or classroom. It is used to store shop tools, small equipment, and supplies. • Every year, thousands of technicians are injured or killed on the job. Many of these accidents resulted from a broken safety rule. • Fires are capable of causing injury and death. There are numerous combustible substances found in an auto shop. • Gasoline is by far the most dangerous and often underestimated flammable substance in an auto shop. • Electrical fires can result when a hot wire touches ground. • An explosion is rapid combustion that causes a powerful shock wave to travel through the shop. • Asphyxiation occurs when someone is deprived of oxygen. It can be caused by breathing airborne toxic or poisonous substances. • Respirators should be worn when working around hazardous airborne materials. • Electric shock occurs when electric current passes through your body. Electrocution can cause injury or death. • Physical injuries, such as cuts, broken bones, and strained backs, can result from a variety of accidents. Activities 1.
