When working around a load that has been raised with a hydraulic jack, it is essential for the load to be properly blocked to prevent any potential accidents or injuries. Blocking the load provides stable support and ensures that it will not collapse unexpectedly. Hydraulic jacks can sometimes fail or lose pressure, and if the load is not adequately blocked, it could fall, posing a severe risk to anyone in the vicinity.

The use of blocking materials, such as wooden blocks or steel supports, helps distribute the weight of the load evenly and reduces the risk of the jack slipping. This procedural step is critical in maintaining safety during any lifting operation.

While safety glasses, clearing the area, and checking for leaks are also important safety practices in a general work environment, the fundamental requirement before working around a raised load involves ensuring that it is securely blocked to prevent it from dropping. This precaution is central to maintaining a safe work environment when using hydraulic equipment.
