Health and safety rules when operating a vehicle. All service, maintenance and repair work, where the employee must be under the car, should take place at stations equipped with ducts, platforms or suitable lifts. Lying under the car should be avoided or only performed in exceptional circumstances, taking all precautions. The working area under the car should always be clean, because the rags accumulated there by carelessness or carelessness, residual lubricants, etc.. can cause a fire that is difficult to control. The engine must not be started when working under the car. Only a driver with a driving license may introduce a vehicle to the sewer pit. It is forbidden to use random objects as wheel chocks.
