2.1 Theoretical principles
2.1.1 Motor vehicle repair and servicing works
In the motor vehicle repair works, a number of processes are undertaken depending on the part under repair or service. This includes but not limited to, bodyworks, engine parts, transmission parts and auxiliary parts like batteries. Operations on this parts during either repair or servicing is prone to expose the worker to some dust mostly inform of fumes.
Hazardous materials and wastes in a motor vehicle workshop
Mechanics are exposed to a wide range of chemicals that include heavy metals such as the ones contained in brake fluids, detergents, lubricants, degreasers, paints, metal cleaners, solvents and fluids. Constant exposure to these chemicals will lead to chronic poisoning.
2.1.2 Hazardous substances found in the repair workshops
Fuel Antiknock Agents
An antiknock agent is a fuel additive which increases the fuel combustibility and reduces engine knock. Antiknock agents are usually made up of methylpentadienyl manganese tricarbonyl (MMT) or ketone solvents like methyl isobutyl keton.
These ingredients may lead to eye irritation, dizziness, breathing problems, nausea and headaches. Long-term exposure to MMT damages the kidneys and liver. Manganese is a neurotoxin which may be absorbed into the blood through the lungs by inhalation, through to the central nervous system leading to neurological syndrome known as manganism. Symptoms include impaired motor skills and
