Health and safety rules when assembling and disassembling an axle or suspension. All work under the car is classified as hazardous, if the worker does not take all the necessary precautions. As you know, all work where the employee must be under the car, should take place at stations equipped with ducts, platforms or suitable lifts. Working under a car is one of the jobs that tire the employee quickly, due to the uncomfortable position and not always appropriate climatic conditions. To facilitate this work, additional portable platforms should be used (steps) different heights, allowing the employee to take the most comfortable position. Please note, that workstations under the car are places exposed to dirt and grease. So you have to keep them clean, because dirty positions pose a high risk and are very often a source of accidents. In the absence of channels, before starting work under the car, the worker should secure the vehicle with wedges against automatic rolling away. If a part of the car is lifted with a portable lift, it is the wheels with the load that should be blocked with chocks. It is forbidden to use as wedges for brick wheels, stones, worn parts of wheel discs and other random items. It is forbidden to perform any service and repair work with a raised vehicle, supported only on a lift..
