Got a lock and key. So now with this on there, you can't turn the valve. Approximately 10% of all industrial accidents are caused by failure to properly control hazardous energy. It actually doesn't take much amperage or voltage to actually cause electrocution. So even the simplest thing, like touching a screwdriver against an electrical socket that has 110 power can be fatal at times. Yet one of the most effective control procedures is also among the most poorly utilized and understood. He never knew what hit him. Unfortunately, that's often the sad story when a failure of the lockout procedure causes an accident, an injury, or even a fatality. The purpose of this program is to protect you, your shipmates, and anyone working on equipment in the presence of hazardous energy. This program is in four sections, an introduction and overview, defining and locating sources of hazardous energy and equipment, locks and tags to be used in the process, and correct procedures to follow for safe operations. Lockout is one of the essential risk management procedures designed to protect seafarers and vessels. Its purpose is to ensure isolated sources of energy can't be reinstated to equipment or spaces where work is being performed. This prevents startups, or unintentional machine operation, that could cause serious injury. As simple as lockout tagout is, as important as it is, it has serious consequences if not followed properly. Al Rainsberger of Foss Maritime trains his team in both shipboard and shoreside lockout procedures. We require people to be retrained constantly, usually on an annual basis. Or if a new piece of equipment is actually instituted into the workplace, our employees will actually receive additional training as well. It's critical. The lockout procedure begins with communication, work planning that specifies where machinery or energy sources must be isolated to ensure a safe working environment. Crew members then use a system of locks and tag identifiers, as well as logging and record keeping, to perform the lockout in four steps: plan, isolate, verify, and lock. The lockout procedures should include any process or place where there is the possibility that the equipment could be restarted or re-energized while someone is working on it or in it. The most important steps about lockout tagout, really, is understanding the piece of equipment you're working on, number one, and the potential of the types of energy it may store, be it electrical, or high-pressure hydraulics, the person needs to understand that that's really critical to know that prior to doing any maintenance at all. A vessel is full of potential hazards, not only during regular operations, but also when maintenance or repair is required. Sources of hazardous energy include electrical, hydraulic, pneumatic devices using compressed air, thermal energy, steam, and kinetic energy in devices such as springs. Hazardous equipment applies to the physical plant itself, machinery, tools, and fittings, pressurized lines or lines containing dangerous or flammable materials, and enclosed spaces. The key to the lockup process is isolation, separating the hazards from the people. You create a barrier, you create isolation between the equipment and its hazards and the personnel working on that equipment. Let's start from the beginning. So we have, you can see, a lot of padlocks here. The lockout equipment itself must be kept up to date and ship shape. Lockout stations should be orderly and inspected regularly. Each ship must maintain a checklist of its lockout equipment and monitor the various lockout stations onboard. Remember that every ship is different, and company login tag systems can vary, including the storage and maintenance of lockout tagout equipment and specific procedures. But the basics always apply. Become familiar with your own ship and system, and train and practice accordingly. Anyone who works on an energized piece of equipment has the potential to have serious harm and possibly death. And that's why we have an effective program and our employees are trained through our program as well. Essential equipment may include locks and isolation tags, multi-lock devices used for single energy source isolations, a group isolation system used when isolating multiple energy sources, and the lockout stations themselves. The isolation lock tag is often a two-part tag. An upper section accompanies the isolation lock, and a lower tear-off section is placed in the lockout station in place of the lock that has been used. The bottom section of an isolation tag, properly filled out and placed on the correct hook in the lockout station, allows any person looking for the isolation source to immediately identify that location. Your own lockout procedures may vary according to company and ship policy. But it's important that you include these procedures as part of your normal training and drilling. And for the most effective training, demonstrate the use of the equipment and the correct process. Effective lockout procedures begin with shared communication. During the daily work planning meeting, identify areas and equipment where lockout will be required, as well as roles and responsibilities. The United States Occupational Safety and Health Administration, OSHA, designates two key sets of responsibilities, affected individuals, who will actually be working on energized equipment, and authorized individuals, who actually lead and implement the lockout tagout procedure. During this meeting, an Isolation Coordinator is appointed, the authorized individual in charge of the lockout process. When required by the relevant procedure, cold work or high voltage work, for instance, a permit to work and a job hazard analysis should also be included. The JHA must list all hazards and specify isolation and lockout points. During this planning process, identify all areas and equipment you propose to lock out, appoint the isolation coordinator, and determine whether you will be locking out single or multiple sources of energy. After the planning process is completed, proceed to the isolation itself. But first, make sure all switches, valves, and control points are in the off position, so when the work is done and power is restored, the equipment doesn't suddenly resume function. If you're working with hydraulic or pneumatic equipment, check the units to make sure the pump is not operating, and check the pressure gauge. Bleed the pressure from all lines and units, and if the system has an accumulator, open the discharge valves and discharge the pressure back into the tank. A variety of devices and equipment can be used as isolators, including hasps, multi-lock devices, valve handle clamps, circuit breaker clamps, fuse blanks, pneumatic lock valves, cable lock devices, and chains. The Isolation Coordinator must verify before any lockout takes place, ensuring that the equipment cannot operate after the isolation, checking that there is no remaining energy flowing from the origin point of that energy, and attaching isolators and isolation locks only after this verification is completed. When there are multiple sources of energy to be locked out, you may wish to utilize a group isolation system and a separate set of group isolation locks. Be aware whenever there are multiple sources of energy, and take special precautions. An employee may attempt to turn on the electrical panel because it may feed multiple sources. And they may not be aware that I was doing maintenance on lathe wave number five when they want to do something with lathe number two and have it activated. During the lock procedure, all keys should be secured it with the Isolation Coordinator or on an isolation board or locker, proper tags should be posted, and for efficient operation, the proposed duration of the lockout and the name of the Isolation Coordinator responsible noted as well. Some lockout procedures can require a lockout plus regime, where a backup or secondary action further isolates the hazardous energy. This may include removing a fuse or another critical working part that eliminates room for error. Now work is ready to begin. Each worker should first have participated in a toolbox talk and understand how the various energy sources have been isolated. Once the isolation locks are in place, . It is physically impossible for another worker to reinstate the isolated equipment Once work is done, the Isolation Coordinator ensures that each task is fully complete and that the affected individuals have checked in and verified their status. He can then remove the isolation locks and isolators. Once removed, the equipment can be re-energized and safe operation confirmed. In summary, remember the four steps. Plan through communication with the Isolation Coordinator. Isolate by determining the sources of all hazardous energy. Verify by checking all sources and your proposed isolations. And lock by logging out and tagging accordingly, including any backup isolations, and securing all keys for safekeeping. Lockout tagout is one of the key risk management tools available onboard ships. Develop your own written program, and train to it faithfully and regularly. The correct use of lockout tagout equipment and following strict procedures can create a safer work environment and protect lives.
