After studying this chapter, you will be able to:Describe the typical layout and sections of anauto shop.List the types of accidents that can occur in anauto shop.Explain how to prevent auto shop accidents.Describe general safety rules for the auto shop.

An auto shop can be a safe and enjoyable place towork. Most shops are clean, well lighted, and relativelysafe, Figure 5-1. However, if basic safety rules are notfollowed, an auto shop can be very dangerous. In thischapter, the layout of a typical automotive service facilitywill be discussed and the most important safety rules willbe emphasized.Auto Shop Layout

There are several different areas in an auto shop. Youmust know their names and the basic rules that apply toeach. It is important that you learn your shop layout andorganization to improve work efficiency and safety. Theauto shop includes the following work areas:

Repair area includes the shop stall, lift, alignment rack, and outside work area .

epair reaThe repair area includes any location in the shop

where repair operations are performed. It normallyincludes every area except the classroom, locker room,and toolroom.Shop Stall

A shop stall is a small work area where a car can beparked for repairs. Sometimes, each stall is numberedand marked off with lines painted on the floor.Lift

The l t is used to raise a vehicle into the air. Refer toFigure 5-2. It is handy for working under the car

permission before using the lift. Center the vehicle on the lift as described in a ser

vice manual, Figure 5-3. Raise vehicle slowly. Check ceiling clearance before raising trucks andcampers. Make sure the vehicle roof does not hit

overhead pipes, lights, or the ceiling. Make sure the lift s safety catch is engaged. Donot walk under the lift without the catch locked

into position, Figure 5-4.Figure 5-5. An alignment rack is used in most shops. It is oftenneeded when servicing steering and suspension systems.Hunter

Control arm-Caution: Do not lift on control arms

when replacing worn suspension and steering parts oradjusting wheel alignment.

When using an alignment rack, the car should bepulled onto the rack slowly and carefully. Someoneshould guide the driver and help keep the tires centeredon the rack. As with other complicated and potentiallydangerous equipment, obtain a full demonstration beforeusing the alignment rack.

The classroom is used for seminars, demonstrations,and other technician training activities. It is often locatedadjacent to the repair area.

Outside Work AreaSome auto shop facilities have an outside work area

adjacent to the garage overhead doors. In good weather,this area can be used for auto repairs.

Always raise the shop doors all the way and pull carsthrough the doors very slowly. Check the height of trucksand campers to make sure they will clear top of vehiclewill not hit doors).

The toolroom is used to store shop tools, smallequipment, and supplies nuts, bolts, oil, etc.). It is normally located adjacent to next to) the repair area orclassroom.

When working in the toolroom, you will be responsible for keeping track of shop tools. Every tool checkedout of the toolroom must be recorded and called in beforethe end of the class period.

Normally, the tools hang on the walls of the toolroomfor easy access. Each tool may have a painted silhouette,which indicates where it should be kept, Figure 5-6.Your instructor will detail specific toolroom policies andprocedures.

Shop SafetyEvery year, thousands of technicians are accidentally

injured or killed on the job. Most of these accidentsresulted from a broken safety rule. The injured personslearned to respect safety rules the hard way-by experiencing a painful injury. You must learn to respect safetyrules the easy way-by studying and following the safetyrules given in this book.

NoteSpecific safety rules on hand tools, power toolsshop equipment, and special operations aregiven elsewhere in this text. It is much easier tunderstand and remember these rules when theare covered fully.

While working, constantly think of safety. Look funsafe work habits, unsafe equipment, and other potentials for accidents. See Figure 5-7.

When working in an auto shop, you must alwayremember that you are surrounded by other techniciansThis makes it even more important that you concentrate osafety to prevent injury to yourself and to others in the sho

Types of AccidentsBasically, you should be aware of and try to prevensix kinds of accidents: Fires. Explosions. Asphyxiation airborne poisons). Chemical burns. Electric shock. Physical injuries.If an accident or injury occurs in the shop, notif

your instructor immediately. Use common sense whedeciding whether to get a fire extinguisher or to takother actions.

Fires are terrible accidents capable of causing severery and permanent scar tissue. Therefore, every precaumust be taken to prevent fires in the automotive shop.There are numerous combustible substances (gaso, oily rags, paints, thinners) found in an auto shop.

is by far the most dangerous and underestied flammable in an auto shop. Gasoline has astonng potential for causing a tremendous fire. Just aful of gasoline can instantly engulf a car in flames.A few gasoline safety rules include: Store gasoline and other flammables in approved,sealed containers. When disconnecting a vehicle's fuel line or hose,

wrap a shop rag around the fitting to keep fuelfrom squirting or leaking.

Disconnect the battery before working on a fuelsystem.

Wipe up gasoline spills immediately. Do notplace oil absorbent (oil-dry) on gasoline becausethe absorbent will become highly flammable.

Keep any source of heat away from fuel systemparts.

Never use gasoline as a cleaning solvent.Oily rags can also start fires. Soiled rags should beed in an approved safety can (can with lid).Paints, thinners, and other combustible materialsuld be stored in a fire cabinet. Also, never set flamles near a source of sparks (grinder), flames (welderater heater), or heat (furnace for example).Electrical fires can result when a hot wire (wireying current to component) touches ground (vehiclee or body). The wire can heat up, melt the insulation,bum. Then, other wires can do the same. Dozens of

es could bum up in a matter of seconds.To prevent electrical fires, always disconnect the batwhen told to do so in a service manual. If possible,

p the battery disconnected during repairs.Locate the fire extinguishers in your shop and learnto use them before they are needed. The few seconds

nt learning how to operate a fire extinguisher could bedifference between life and death during a fire.Figure 5-8 shows various fire classifications and firenguisher types. Always use the recommended type ofnguisher. Using the wrong extinguisher can actuallyse the flames to spread. Multipurpose fire extinhers can be used for a variety of fires. The mostmon type of multipurpose extinguisher is an A, B, C,chemical fire extinguisher.


To use a fire extinguisher, pull the safety pin from thehandle. Aim the nozzle at the flames as outlined inFigure 5-8 and squeeze the extinguisher handle.

ExplosionsAn explosion is the rapid, almost instant, combustion

of a material that causes a powerful shock wave to travelthrough the shop. Several types of explosions are possible in an auto repair facility. You should be aware ofthese sources of sudden death and injury.

Hydrogen gas can surround the top of a car batterythat is being charged or discharged (used). This gas ishighly explosive. The slightest spark or flame can ignitethe hydrogen gas, causing the battery to explode. Batteryacid and pieces of the battery case can blow into youreyes and face. Blindness, facial cuts, acid bums, andscars can result. Always wear eye and face protectionwhen working around a battery. See Figure 5-9.

Fuel tanks can explode, even seemingly empty ones.A drained fuel tank can still contain fuel gum and varnish. When this gum is heated and melts, it can emitvapors that may ignite.

Keep sparks and heat away from fuel tanks.When a fueltank explodes, one side will usually blowout. Then, the tankwill shoot across the shop as if shot out of a cannon. You orother workers could be killed or seriously injured.

Various other sources can cause shop explosions. Forexample, special sodium-filled engine valves, weldingtanks, and propane-filled bottles can explode if mishandled. These hazards will be discussed in later chapters.

WarningAir bags should be handled with extreme care.If accidentally deployed, they can break bonesor even kill. Carry them with the metal housingfacing downward and away from your body.Keep all sources of electricity away fromundeployed air bags.

sphyxiation sphyxiation is caused by breathing toxic or poiso

nous substances. Mild cases of asphyxiation will causedizziness, headaches, and vomiting. Severe asphyxiationcan cause death.

The most common cause of asphyxiation in an autoshop is the exhaust gases produced by an automobileengine. Exhaust gases are poison If a vehicle must beoperated in an enclosed shop, connect the vehicle'stailpipe to the shop's exhaust ventilation system as shownin Figure 5-10. Also, make sure the exhaust ventilationsystem is turned on

Discussed in related chapters, other shop substancesare harmful if inhaled. A few of these harmful substancesinclude asbestos brake lining dust, clutch disc dust ,parts cleaners, and paint spray. Respirators filter masksshould be worn when working around any airborne impurities. Refer to Figure 5-11.hemical urns

Solvents parts cleaners , battery acid, and variousother corrosive shop substances can cause chemicalburns to the skin. Always read the directions on allchemical containers. Also, be sure to wear proper protective gear when handling solvents and other causticmaterials. See Figure 5-12.

Carburetor cleaner (decarbonizing types), formple, is very powerful and can severely burn yourn in a matter of seconds. Wear rubber gloves whenng carburetor cleaner. If a skin burn occurs, followel directions.

WarningIf your eyes are chemically burned, the materialsafety warning label may recommend flushingthem with water. An eyeflushing station issometimes used to wash chemicals from youreyes after an accident.

ectric ShockElectric shock is a result of electric current passing

ough parts of your body, causing injury or death. It canur when using improperly grounded electric powerNever use an electric tool unless it has a functionalnd prong (third, round prong on plug socket). This

vents current from accidentally passing through youry. Also, never use an electric tool on a wet shop floor.

WarningSome late-model cars have heated windshields.The alternators on these vehicles are designedto put out more than 100 volts ac to quicklywarm the windshield. This is enough voltage tocause electric shock. Work carefully around thishigh voltage.

rid SafetyHybrid vehicles use a high-voltage motor-generatora battery pack that operates on approximately

-600 volts. This is enough electrical energy to causeious injury or even electrocution Voltage levels andrid service procedures vary. Therefore, it is importantfollow the vehicle manufacturer's instructions andety rules when working on a specific make and modelAlways wear rubber electrician's gloves (rated for

00 volts) when working on a high-voltage hybrid drivetem. The thick rubber gloves will prevent electricck if you accidentally touch a conductor carrying hightage and current.Most hybrids have a main power cutoff switch or

ll switch, near the output cables of the battery pack.is switch allows you to electrically disconnect the baty pack from the rest of the hybrid drive system. Ituld be turned to the off position before servicing aid drive system.

Physical InjuryPhysical injuries (cuts, broken bones, straine

backs) can result from hundreds of different accidents. Aa technician, you must evaluate every repair techniqueDecide whether a particular operation is safe and takaction as required.

For instance, if you are pulling on a hand wrenchhard as you can and the bolt will not turn, stop Finanother wrench that is larger. A larger tool has moleverage and is, therefore, safer. This approach will heprevent injuries and improve your mechanical abilities.

WarningNever overexert your back by improperly liftinheavy assemblies. Once you injure your back,can take months to recover. Sometimes, surgeryis needed to repair the damage. When lifting aheavy object, keep your back straight. Bend youknees and lift the item with your legs. If necessary, use power equipment to move heavy object

eneral Safety RulesListed are several general safety rules that should bfollowed at all times. Wear eye protection during any operation th

could endanger your eyes. This would includoperating power tools, working around a runnincar engine, carrying batteries, etc.

Avoid anyone who does not take shop work serously. Remember, a joker is an accident juwaiting to happen.

Keep your shop organized. Return all tools anequipment to their proper storage areas. Never latools, creepers, or parts on the floor.

Dress in an appropriate manner. Never wear loosclothing, neckties, shorts, or open-toed shoes wheworking in the shop. Remove rings, braceletsnecklaces, watches, and other jewelry. They caget caught in engine fans, belts, drive shafts, another rotating parts, causing serious injury. Alsobutton or roll up long sleeves and secure lonhair; they too can get caught in spinning parts.

Never carry sharp tools or parts in your pocketsThey can puncture the skin.

Wear full face protection when grinding, weldingand performing other operations where sevehazards are present.

Work like a professional. When learning aurepair, it is easy to get excited about your wor

However, avoid working too fast. You could overlook a repair procedure or safety rule.

Use the right tool for the job. There is usually abest tool for each repair task. Always be thinkingabout whether a different tool will work better thananother, especially when you run into difficulty.

Keep guards or shields in place. If a power toolhas a safety guard, use it.

Lift with your legs, not your back. There aremany assemblies that are very heavy. Whenlifting, bend at your knees while keeping yourback straight. On extremely heavy assemblies(transmissions, engine blocks, rear axles,transaxles), use a portable crane.

Use adequate lighting. A portable shop light notonly increases working safety, but it increasesworking speed and precision.

Ventilate when needed. Turn on the shop ventilation fan anytime fumes are present in the shop. Never stir up asbestos dust. Asbestos dust (parti

cles found in brake and clutch assemblies) is apowerful cancer causing agent Do not use compressed air to blow the dust from brake andclutch parts. Use an enclosed vacuum system toremove asbestos dust from brake assemblies.

Jack up a vehicle slowly and safely. A car canweigh between one and two tons. Never workunder a vehicle not supported by jack stands. It isnot safe to work under a vehicle supported byonly a floor jack. See Figure 5-13.

Drive slowly when in the shop area. With all theother students and vehicles in the shop, it is veryeasy to have an accident.


Report unsafe conditions to your instructor. If yonotice any type of hazard, let your instructoknow about it.

Stay away from engine fans. The fan on an enginis like a spinning knife. It can inflict seriouinjuries. Also, if a part or tool is dropped into thfan, it can fly out and hit someone. Electric fancan turn on even with the ignition key off Respect running engines. When an engine is running, make sure the transmission is in park oneutral, the emergency brake is set, and thwheels are blocked. If these steps are not takeand the car is accidentally knocked into gear,could run over you or a friend.

Do not smoke in the auto shop. Smoking is a serous fire hazard, considering fuel lines, cleaning sovents, paints, and other flammables may be exposed

Read material safety data sheets when in doubabout any dangers. The material safety data sheecontains all the information needed to work safelwith the hazardous material. See Figure 5-14.

Obtain instructor permission before using annew or unfamiliar power tool, lift, or other shoequipment. If necessary, your instructor will giva demonstration.

ustomer elationsMost shop insurance policies do not cover cus-

tomers who enter the shop work area. When informingcustomers that they are not allowed in the repair areaexplain that the insurance company not the shop hasmade this rule. This will help prevent the customer frombeing offended by being told to leave the work area.
