Safety first Professional motor mechanics are trained in safe working proce dures However enthusiastic you may be about getting on with the job in hand do take the time to ensure that your safety is not put at risk A moment s lack of attention can result in an accident as can failure to observe certain elementary precautions There will always be new ways of having accidents and the following points do not pretend to be a comprehensive list of all dangers they are intended rather to make you aware of the risks and to encourage a safety conscious approach to all work you carry out on your vehicle Essential DOs and DON Ts DON T start the engine without first ascertaining that the transmission is in neutral DON T suddenly remove the filler cap from a hot cooling system cover it with a cloth and release the pressure gradually first or you may get scalded by escaping coolant DON T attempt to drain oil until you are sure it has cooled sufficiently to avoid scalding you DON T grasp any part of the engine exhaust or silencer without first ascertaining that it is sufficiently cool to avoid burning you DON T allow brake fluid or antifreeze to contact the machine s paintwork or plastic components DON T syphon toxic liquids such as fuel brake fluid or antifreeze by mouth or allow them to remain on your skin DON T inhale dust it may be injurious to health see Asbestos heading DON T allow any spilt oil or grease to remain on the floor wipe it up straight away before someone slips on it DON T use ill fitting spanners or other tools which may slip and cause injury DON T attempt to lift a heavy component which may be beyond your capability get assistance DON T rush to finish a job or take unverified short cuts DON T allow children or animals in or around an unattended vehicle DON T inflate a tyre to a pressure above the recommended maximum Apart from overstressing the carcase and wheel rim in extreme cases the tyre may blow off forcibly DO ensure that the machine is supported securely at all times This is especially important when the machine is blocked up to aid wheel or fork removal DO take care when attempting to slacken a stubborn hut or bolt It is generally better to pull on a spanner rather than push so that if slippage occurs you fall away from the machine rather than on to it DO wear eye protection when using power tools such as drill sander bench grinder etc DO use a barrier cream on your hands prior to undertaking dirty jobs it will protect your skin from infection as well as making the dirt easier to remove afterwards but make sure your hands aren t left slippery Note that long term contact with used engine oil can be a health hazard DO keep loose clothing cuffs tie etc and long hair well out of the way of moving mechanical parts DO remove rings wristwatch etc before working on the vehicle especially the electrical system DO keep your work area tidy it is only too easy to fall over articles left lying around DO exercise caution when compressing springs for removal or installation Ensure that the tension is applied and released in a controlled manner using suitable tools which preclude the possibility of the spring escaping violently DO ensure that any lifting tackle used has a safe working load rating adequate for the job DO get someone to check periodically that all is well when working alone on the vehicle DO carry out work in a logical sequence and check that everything is correctly assembled and tightened afterwards DO remember that your vehicle s safety affects that of yourself and others If in doubt on any point get specialist advice IF in spite of following these precautions you are unfortunate enough to injure yourself seek medical attention as soon as possible Asbestos Certain friction insulating sealing and other products such as brake linings clutch linings gaskets etc contain asbestos Extreme care must be taken to avoid inhalation of dust from such products since it is hazardous to health If in doubt assume that they do contain asbestos Fire Remember at all times that petrol gasoline is highly flammable Never smoke or have any kind of naked flame around when working on the vehicle But the risk does not end there a spark caused by an electrical short circuit by two metal surfaces contacting each other by careless use of tools or even by static electricity built up in your body under certain conditions can ignite petrol vapour which in a confined space is highly explosive Always disconnect the battery earth ground terminal before working on any part of the fuel or electrical system and never risk spilling fuel on to a hot engine or exhaust It is recommended that a fire extinguisher of a type suitable for fuel and electrical fires is kept handy in the garage or workplace at all times Never try to extinguish a fuel or electrical fire with water Fumes Certain fumes are highly toxic and can quickly cause unconscious ness and even death if inhaled to any extent Petrol gasoline vapour comes into this category as do the vapours from certain solvents such as trichloroethylene Any draining or pouring of such volatile fluids should be done in a well ventilated area When using cleaning fluids and solvents read the instructions carefully Never use materials from unmarked containers they may give off poisonous vapours Never run the engine of a motor vehicle in an enclosed space such as a garage Exhaust fumes contain carbon monoxide which is extremely poisonous if you need to run the engine always do so in the open air or at least have the rear of the vehicle outside the workplace The battery Never cause a spark or allow a naked light near the vehicle s battery It will normally be giving off a certain amount of hydrogen gas which is highly explosive Always disconnect the battery earth ground terminal before working on the fuel or electrical systems If possible loosen the filler plugs or cover when charging the battery from an external source Do not charge at an excessive rate or the battery may burst Take care when topping up and when carrying the battery The acid electrolyte even when diluted is very corrosive and should not be allowed to contact the eyes or skin If you ever need to prepare electrolyte yourself always add the acid slowly to the water and never the other way round Protect against splashes by wearing rubber gloves and goggles Mains electricity When using an electric power tool inspection light etc which works from the mains always ensure that the appliance is correctly connected to its plug and that where necessary it is properly earthed grounded Do not use such appliances in damp conditions and again beware of creating a spark or applying excessive heat in the vicinity of fuel or fuel vapour Ignition HT voltage A severe electric shock can result from touching certain parts of the ignition system such as the HT leads when the engine is running or being cranked particularly if components are damp or the insulation is defective Where an electronic ignition system is fitted the HT voltage is much higher and could prove fatal
