[1] Seasoned auto repair shops start with a (Digital) Inspection to determine the vehicle conditions, independent of the customers concern.

Based on the concern, the inspection results and preventative maintenance needs, the mechanic/technician returns the findings to the service advisor who then gets approval for any or all of the proposed work.

A professional's skill level is usually determined by years of experience and certifications: A vehicle's Original Equipment Manufacturer (OEM) often provides and requires additional training as part of the dealership franchise agreement.

These types of programs may be paid for by a student with no obligation, or by the manufacturer with a contract that requires a professional to work for the OEM for a designated amount of time upon graduating.

These mechanics utilize large tubing benders and welders to fabricate a new exhaust system out of otherwise straight lengths of pipe.

A lubrication professional, often shortened to lube tech, is an entry-level position that focuses on basic preventive maintenance services rather than repairs.

The tasks that can be performed are typically limited to automotive fluid, filter, belt, hose replacement and often times tire maintenance.

Pit crew jobs include raising and lowering the vehicle with a jack, filling the car with gasoline, changing the tires, and cleaning the windshield.

The auto mechanic has a physically demanding job, often exposed to loud noises,[8] equipment, slippery surfaces, vehicle parts, tools, falling objects, fires, explosions, and more.

The Occupational Safety and Health Administration's general standards address the physical hazards that may appear in workplace settings and how to avoid them properly.

[14] These resources emphasize the importance of PPE (personal protective equipment), manual handling devices, and a clean workplace for reducing the risk of physical harm.

Common chemical and material exposures for auto mechanics can include engine exhaust, solvents, dust as a result of sanding or abrasive blasting, spray from paints, cleaning products, and asbestos from brake and clutch repair.

[15] As a result of these exposures, auto mechanics can face increased risks for developing mesothelioma, bladder, digestive, lung, and pancreatic cancers, as well as heart disease and other cardiovascular disorders.

[17] Workplaces with auto mechanics should also create a hazard communication program in order to protect their employees from chemical exposures.

Additionally, auto mechanic workplaces should have regular testing done in order to ensure that there is both proper ventilation and that air contaminant levels are safe and conducive to reducing overall worker exposure.

This is critical, as paint exposure can lead to nervous disorders, skin and eye irritation, asthma, and a reduction in lung function.

There are several other trade qualifications for working on motor vehicles, including panel beater, spray painter, body builder and motorcycle mechanic.
