This prevents any accidental startups while another employee may still be working on the machinery. z When all energy sources are locked, inform others of the lockout situation. One way to do this is by applying a tag to the power source. z Equipment must be at “zero energy state” before servicing or maintenance work can begin to get to this state。 z Drain all valve, bleed off air from a system, eliminate stored hydraulic pressure, or use any method to release energy that is detailed in your pany procedure. z Test machine to assure that all energy was disconnected or released z After servicing is finished remove all tools from area and replace all machine guards. z Remove your tag and lock z Reconnect all sources of energy z Restart the equipment 256, Machine and Tools 1) Compressed Gases z Cylinders shall not be accepted unless approved by relevant mission. z Cylinders shall be carried or rolled on bottom end and never dragged, dropped, or moved by electric magnets and rope slings, unless a specially designed cradle is provided in the sling. z Cylinders shall always be considered as full and handled with corresponding care. z Cylinders shall be kept in wellventilated places and away fro any sources of excess heat. When places inside buildings, they shall be kept away from highly bustible materials, such as oil and excelsior, and away from stoves, radiators, and furnaces. z Cylinders shall be stored securely by positive methods and in a definitely assigned place, away from elevator, gangways, and other places where they are likely to be knocked over or damaged by passing or falling objects. z Cylinders of oxygen shall not be stored in close proximity to cylinders of acetylene and other pressed gases inside buildings. Unless well separated, there shall be a fireresisting partition between the oxygen cylinders and other pressedgas cylinders. z Where cylinders are stored in the open, they shall be protected from accumulations of ice and snow and from the continuous direct rays of the sun in locations where high temperatures prevail. 2) Fork lift A: Driving fork lift z Only a trained and authorized operator should drive a forklift. z Only the assigned driver should operate a forklift. z No using the forklift, which needs repair, in any way unsafe, the forklift shall be taken out of service until it has been restored to safe operating condition. z High lift rider truck shall be equipped with a substantial overhead guard unless operating conditions do not permit. z Fork trucks shall be equipped with a vertical load backrest extension when the type of load presents a hazard to operator. z The brakes of highway truck shall be set and wheel chocks placed under the rear wheels to prevent the truck from rolling while they are boarded with forklift trucks. 26 B: Safe Fork Lift Driving Rules z Keep to the right z Obey speed limits z Keep three vehicle lengths away from other vehicles z Slow down at all intersections z The pedestrian always has the right of way z No horse play is allowed z No riders are allowed, not on the forks, not on the seat, not on the back z Always keep arms and legs inside the vehicle z Face the direction of travel z Know the position of your forks at all times z Be aware of overhead clearances, if working in solid storeroom must wear safety helmet. z Be alert for oil and grease spots z Be careful of changing light conditions z No towing or pushing is allowed z Beware of edges on loading docks z Always check the wheels of a truck being loaded or unloaded. z Stop pletely before raising or lowering a load z Make sure forks extend pletely into a pallet z Never travel with a load raised high z Make travel with a load is balanced and secure z Do not move loads on broken pallets, loads beyond the known capacity of the fork lift or loads that are unbalanced C: Forklift inspection and maintenance Since panies have different types of lift devices made by a variety of manufacturers, the handson preoperational inspection is very impotent. Among the points to be made: ? Procedures for operators to report repairs ? Verification of repairs ? The obligation to refuse to work with unsafe equipment ? Mounting and dismounting procedures. Many accidents are caused by operators slipping or jumping from their units。 ? Refueling stops are especially critical. D: A model safety check starts with this walkaround inspection z Check fork pins and stops to make sure they are in place z Check all cowling and body parts z Check wheels and tires z Check for any broken or loosened parts z C
