![]() ![]() Problems: There is no block under the upper die to positively prevent it from coming down. In the photo, the setup person is installing and adjusting the dies for production stamping of a composite material. Setup - a particular type of service to a machine when it is being prepared for production use. Think of a compressed spring, or a pressured line that has not been bled off.”Īdjusting Lubricating Set-up (Preparing for normal function) Service/Repair “Service & Maintenance - when the machine isn’t being used for actual production and service, repair or maintenance work is being done. These examples are considered hazardous, because just “turning them off” does not guarantee they won’t accidentally be turned on again during maintenance or repair, or they continue to have stored energy after being “turned off”. ![]() Live electrical lines Electrical capacitors Lasers Engines that move machinery parts Hydraulic lifts Pneumatic (air pressure) lines Springs “Other examples include forklifts with the forks in the up position, steam and hot liquid pipes, fuel lines such as natural gas to heaters. Stored heat (steam lines or hot liquids) Chemicals in pipelines under pressure or force of gravity Any other active or stored energy sources that could harm a worker “Chemicals may not seem like stored energy in the normal meaning of the word, but some chemicals like acids, would cause injury if suddenly sprayed or splashed on a worker, thinking a pipeline is empty, disconnects a pipe or opens a valve.” In the truck photo, the upraised truck bed has hazardous stored energy because gravity could move it down on top of a mechanic working under it, if the bed is not physically blocked in the up position.” Stored mechanical movement in machinery For example, hydraulic fluids can move machinery parts even when the motor or electricity is off, if a certain valve is opened. This energy can sometimes still exist or be stored when the machinery is turned off. ![]() Authorized employees will be further trained on the specific details and procedures of lockout/tagout as applied in out company.”Įlectricity – live or stored Moving machinery parts “Stored mechanical movement means some part of a machine can be moved by electricity, hydraulic fluid, air pressure, water pressure or gravity. ![]() This training provides an overview of lockout/tagout. The reason for this is that everyone working around machinery should be aware of the hazards of starting up the machinery up while someone is doing maintenance or repair. The person working on this saw obviously would not want someone inadvertently starting up the saw.”Ĥ Who Needs Training? Authorized employees – People who lock or tag out machines or equipment to perform servicing Affected employees – People who use machines or equipment on which servicing is performed under lockout/tagout Other employees – People who work in the area of locked out machinery or equipment “This sounds like almost everybody working around machinery, which is true. When is LO/TO Required? Who Needs Training? Hazardous Energy Examples Lockout Devices Lockout Procedures Tagout Examplesģ When is LO/TO Required? When someone will be servicing or repairing machinery or equipment AND The unexpected machinery start-up or release of stored energy could cause injury “In many fatalities or injuries, another employee will start up a machine or open a valve, not aware that someone else is repairing the machine.
