After verifying, an authorized person from the maintenance department makes sure is all the tools are removed, equipment is clean, temporary grounding is removed and equipment guarding is installed. This is the last step in which when the work is completed and the maintenance department hand over the equipment, the completion of work is being verified by the production department.
In this step, the concern authorized person from production, as well as the maintenance person, verify that the equipment is perfectly isolated from the energy source through the MCC circuit breaker.
LOTO HASP VERIFICATION
No work is considers completed until it is verified and the isolation verification steps are all about checking verification. Hense to avoid accidents from the potentially hazardous stored or residual energy, it should be relieved, equipment needs to be degassed or depressurized to make it non-hazardous. Stored energy is also known as residual energy which is there in form of static energy, air pressure, chemical gas. Although the equipment disconnected, there is still chance that some energy is there in the form of stored energy. In the isolation step, we had isolated the equipment from the energy source. Not only the source of energy, Do not operate, do not start or do not open tag should be applied on the equipment for awareness that the equipment is under maintenance. If the equipment can’t be lockout, tag out needs to be done which includes the name of the authorized person who performs the Tagout procedure. Until the work in not completed and all the locks are not unlocked, equipment can’t be re-energized. Here Padlock is applied to the energy-isolating device where the electrical department, maintenance department and production department, and safety department apply lock and key is to be with the authorized person only. This ensures that no other person can re-energize the equipment until the work is completed. In this step, the authorized persons affix lockout and/or tagout devices to each energy-isolating device. Now the subjected equipment and machine is isolated from the energy source, lock out and tag out machine in the next step. These are the important steps of the lockout and tagout safety procedure.
The emergency stop button of the equipment is not considered for isolation of energy, it should be used but as an extra layer of safety, equipment needs to be shut through the MCC breaker or by a fuse. IsolationĪfter the shutdown step, the next step is isolation in which the Lockout/Tagout procedure is executed, and the machine and equipment in which maintenance or preventive maintenance work needs to be taken are being isolated from the source of energy. In this step, subjected equipment or the machine is being shut down or stoped and all the employees working in the section to be informed about the equipment which needs to be serviced. The shutdown phase includes the execution of the preparation step. In this phase, the permit is being prepared by the production department. It is important to identify the risk involved with hazardous energy in the task which is needed to be conducted hence in the preparation steps along with steps required to control the hazard. This is the first step of LOTO where the production and maintenance department discuss the work that needed to be taken. Preparation of shutdown – (Lock out Tag out Steps) Isolation verification and de-energization of the machine.let us move to the steps of loto and learn each steps in detiails.
lockout tagout safety procedure include six steps which are listed below. Six Steps of LOTO Safety Lock out Tag out Steps Note – In LOTO procedures, isolation of energy is considered by using a circuit breaker, and emergency switches are not included in LOTO procedure for energy isolation.
This LOTO is a written step of procedure and an administrative tool that safely isolates equipment from the source of energy by using a feeder or MCC breaker and tagged is affix so the equipment not gets re-energized by mistake also. What is LOTO? : LOTO stands for Lockout Tagout and it is a procedure that is designed to protect employe while performing maintenance of equipment by unexpected re-energization or release of energy while performing maintenance work of the equipment or machine.
