HAZARDS: Hydraulic equipments and systems are designed to accomplish work using confined liquid pressure to produce a greater mechanical force. The operators/ maintenance crews are subjected to hazards from high pressure liquids and large mechanical forces. Hydraulic systems store fluid under high pressure. The workmen are exposed to following hazards:
➢ burns from hot, high-pressure fluid
➢ Injection of fluid into the skin
➢ Fire Hazards
➢ bruises, cuts or abrasions from flailing hydraulic lines
➢ Injury of people due to unexpected movement of equipment.
➢ During maintenance of equipment and their parts.
➢ Injury due to sudden release of residual pressurized oil.
➢ Slippage due to oily floor area.
SAFETY 1) Positive isolation procedure to be followed before start of any hydraulic work. 2) Depressurize the system before start of work. Shut down/ Local Isolation may be taken, if required. 3) Never begin work on a hydraulic/pneumatic system until fully trained. 4) Never begin work on a hydraulic/pneumatic system without using a risk assessment. 5) Carefully review the manuals on equipments before beginning work. Ask questions about anything you do not fully understand. 6) Use all required safety Equipments like gloves,masks etc. 7) Never try to repair a part without having full knowledge about it. 8) Each hydraulic system must have a documented procedure of deenergizing and load locking. This should be known to all maintenance personnel. 9) Document and practice de-pressurizing procedure in each of the circuit. 10) While testing the system after repair never stand close to the unit. Any component, pipe, hose, fitting may fail. 11) Tightening of Joints should be done in depressurized condition.
