Lockout/tagout in waste management is criticial
Today's waste management is more of a science than anything else. Many collection facilities must store, separate and then find a permanent home for a myriad of waste types. Everything from hazardous waste to recyclables takes additional space and energy to glean from the system. New equipment is making it easier to find and separate a wide range of waste types, but these advancements aren't necessarily eliminating injuries.
|Equipment maintenance presents many hazards|
Approximately 3 million workers service equipment in the United States. OSHA statistics show these workers face the greatest risk of injury when lockout/tagout is not properly implemented. OSHA research has found compliance with the lockout/tagout standard prevents an estimated 120 fatalities and 50,000 injuries each year. Workers injured on the job from exposure to hazardous energy lose an average of 24 workdays for recuperation.
A study conducted by the United Auto Workers (UAW) found that 20% of the fatalities (83 of 414) that occurred among their members between 1973 and 1995 were attributed to inadequate hazardous energy control procedures, specifically lockout/tagout procedures.
Workers need to be better trained than ever to operate the machinery used in this line of work. It's not just a good idea; it's the law. OSHA 29 CFR 1910.147 requires it. One of the best ways to promote lockout/tagout procedures at your facility is to post them directly on equipment or at a nearby, strategic location. There's no limit to label size. When a DuraLabel printer is used, long procedures can be printed and tiled so the size accommodates your needs. Keep in mind, the following procedure is just an example. You'll need to develop your own procedures for your specific equipment. Make sure to include start-up procedures with any LOTO procedure.
1 - Notify affected employees that a lock-out or tag-out system is going to be utilized and the reason therefore. The authorized employee shall know the type and magnitude of energy that the machine or equipment utilizes and shall understand the hazards thereof.
2 - If the machine or equipment is operating, shut it down by the normal stopping procedure (call control room operator, depress stop button, open toggle switch, etc.)
3 - Operate the switch, valve, or other energy isolating device(s) so that the equipment is isolated from its energy source(s). Stored energy (such as that in springs, elevated machine members, rotating flywheels, hydraulic systems, and air, gas, steam, or water pressure, etc.) must be dissipated or restrained by methods such as repositioning, blocking, bleeding down, etc.
A. If there is a possibility of re-accumulation of stored energy to a hazardous level, verification of isolation shall be continued until the maintenance or repair is completed, or until the possibility of such accumulation no longer exists.
DANGER!FAILURE TO FOLLOW THE NEXT STEP MAY RESULT IN SERIOUS PHYSICAL HARM OR DEATH.
1) Have a qualified electrician turn off the source of electrical energy if the equipment is electrically energized.
2) Lock-out/Tag-out the energy isolating devices with assigned individual lock(s) or tag(s).
3) Verification of Isolation (electrical only): After ensuring that no personnel can be exposed and as a check on having disconnected the electrical energy source, call the control room operator and have the equipment controls placed in the “Manual” mode and attempt to activate the equipment, the control room operator must verify that they cannot start the equipment. The control room operator must next place the controls in the “Local” mode of operation. Maintenance/servicing personnel must attempt to start the equipment using the local push button or other normal operating controls at the field location to make certain the equipment will not operate. The control room operator must return the controls back to the “Manual” mode of operation and make necessary entries in the lock-out log in the control room. (Verification procedures are located in each group lock-out instructions box in electrical rooms).
CAUTION!RETURN FIELD OPERATING CONTROL(S) TO NEUTRAL OR OFF POSITION AFTER THE TEST.
4 - De-energize, control, or eliminate any remaining energy sources such as air, hydraulic, gravity, or potential motion and install any necessary additional control devices and or lock-out warning tags.
5 - The equipment should now be properly locked out or tagged out.
