First class!! Health and Safety

GeneraI Hazards

Scalding：
1.Don’ t remove the radiator or expansion tank cap white the engine is hot.
2.Engine oll ,automatic transrrlission fluid or power steering fluid rnay also be
dangerously hotifthe engine has recenuy been running.

Burning:
 Beware of burns from the exhaust systern and from any part of the engine.
 Brake discs and drums can also be extremely hot immediately afer use.

Crushing:
1.when working under or near a raised vehicle,always suppIement the jack with axle stands,or use drive-on ramps,Never venture under a car which is onIy supported by a jack.
2.Take care if loosening or tightening high-torque nuts when the vehicle is on stands. lnitial loosening and final tightening should be done with the wheels on the ground.

Fire:
1.Fuel is highly farnrnable fuel vapour is explosive.
2.Don’ t let fuel spill onto a hot engine.
3.Do not smoke or allow naked lights(incIuding pilot lights)anywhere near a
vehicIe being worked on. Also beware of creating sparks(electrically or by use
of tools.)
4.Fuel vapouris heavierthan air,so don’t work on the fuel system with the vehicle
over an inspection pit.
5.Another cause of fires is an electrical overload or short-circuit.Take care when repairing or modifying the vehide wiring
6.Keep a fire extinguisher handy,of a typesuitable for use on fuel and electrical fires.

EIectric shock:
1.Ignition HT vokage can be dangerous especially to people with heart problems or a pacemaker. Don’t work on or nearthe ignition system with the engine running or the ignition switched on.
2.Mains vokage is also dangerous. Make sure that any mains-operated equipment is correctIy earthed. Mains power points shouId be protected by a residual current device(RCD)circuit breaker.

Fume or Gas Intoxication ：
1.Exhaust fumes are poisonous; they often contain carbon rnonoxide,which is rapidly fatal if inhaled. Never run the engine in a confined space such as a garage with the doors shut.
2.FueI vapour is also poisonous,as are the vapours from l some cleaning solvents and paint thinners.

Poisonous or Irritant Substances：
1.Avoid skin contact with battery acid and with any fuel,fluid or lubricant especially antifreeze,brake hydrauic fluid and Diesel fueI. Don’ t siphon them by mouth. If such a substance is swallowed or gets into
the eyes,seek: medical advice.
2.Prolonged contact with used engine oil can cause skin cancer. Wear gloves or use a barrier cream if necessary.Change out of oiI-soaked clothes and do not keep oily rags in your pocket.
3.Air conditioning refrigerant forms a poisonous gas if exposed to a naked flame(including a Gigarette.)lt can also cause skin burns on contact.

Asbestos:
Asbestos dust can cause cancerifinhaled or swallowed. Asbestos may be found in gaskets and in brake and clutch linings. When dealing with such components it is safest to assume thatthey contain asbestos.

Hydroflouric Acid:

1.This extremely corrosive acid is formed when certain types of synthetic rubber,found in some O-rings,oil seals,fuel hoses,etc,are exposed to temperatures above400° C.The rubber changes into a charred or sticky substance containing the acid.Once formed, the acid remains dangerous for years.If it  gets onto the skin,it may be necessary toamputate the limb concerned.
2.VVhen dealing with a vehicle which has suffered a fires,or with components salvaged from such a vehicle,wear protective gloves and discard thern after use.
The Battery:
1.Batteries contain sulphuric acid,which attacks clothing,eyes and skin. Take care when topping-up or carrγing the battery.
2.The hydrogen gas given off by the battery is highly explosive. Never cause a spark or allow a naked light nearby. Be careful when connecting and disconnecting battery charger or jump leads.

Air Bags:
Air bags can cause injury if they go off accidentally. Take care when removing the steering wheel and/or facia. Special storage instructions may apply.

DieseIlnjection Equipment:
Diesel injection pumps supply fuel at very high pressure.Take care when working on the fuel injectors and fuel pipes.

Health and Safety part 2

Read and explain in your own words the FIRE and EVACUATION process including were you should meet if there is a fire, what colour vest do the fire wardens were?

Health and Safety part 3

You need to do a presentation on student safety responsibilities this can be done in a group active on in peers

About Ohm's law      

V = I × R              volt = amp × resistance


A series circuit is one where the current flows through the components one after another. Hence the name series.

A parallel circuit branches off and the current flows through all the components side by side then regroups at the end.
