Person in-charge/Shift in-charge shall be the only agency that will control and shall ensure necessary provision for providing field hasp including hasp for electrical Lockout. Each plant control room shall have a comprehensive procedure of monitoring and control of field, through proper documentation and shift-toshift communication so that no device(s) remain unnoticed. All hardware used for hazardous energy control must be durable enough to withstand the workplace environment and must be used solely for the purpose of control of hazardous energy. .If there is a loss of key, the concerned person shall inform the Person Incharge/Shift in-Charge by a formal written communication about the facts. Division chief shall be the only approving authority for breaking any locks of the energy-isolating device. .For ease of identification of the department to which the executing Persons/Team leader is associated, the locks shall be identified by defined colors as mentioned below- Tag out and Tags: If an energy-isolating device is not capable of being locked out, a tag out procedure (Tagging System) shall be followed. Where Tag out procedure (Tagging System) is used for hazardous energy control, the Person must be fully aware of limitations of tags. Tags are essentially warning devices affixed to energy-isolating devices, and do not provide the physical restraint on those devices that is provided by a lock. Tags may evoke a false sense of security, and their meaning needs to be understood well. When a tag is attached to an energy-isolating means, it shall not be removed without authorization of the authorized Person responsible for it, and it is never to be bypassed, ignored, or otherwise defeated. Tags must be securely attached to energy-isolating devices so that they cannot be inadvertently or accidentally detached during use. Tags must be legible and understandable by all Persons, whose work operations are or may be in the area, in order to be effective. Tags and their means of attachment must be made of materials, which will withstand the environmental conditions encountered in the workplace. Before work is started on any equipment, System or process, the Person In-Charge/Shift In-Charge shall be responsible for Preparation for Lockout / Tag out. Where stored or residual energy (such as that in capacitors, springs, elevated machine members, rotating flywheels, hydraulic systems, and air, gas, steam, or water pressure, etc.) may be encountered, identification of such type(s) of stored or residual energy shall be ensured. Appropriate methods of dissipating or restraining such energy (by methods such as, but not necessarily limited to, grounding, repositioning, blocking, bleeding down, etc.) shall be ensured. He / She shall ensure that all hazardous energy sources are identified (Chemical, Electrical, Mechanical or other) to determine which switches, valves or other energy-isolating devices apply to machinery or equipment to be locked and tagged out For equipment preparation, pertaining to plant operational processes involving line breaks, the prime consideration shall be of proving that isolations are intact and giving a tight shut off. .Each case shall be carefully considered by the Person In-charge/Shift Incharge, taking into account the hazardous properties of the materials involved and the details of plant design. Person In-Charge/Shift In-Charge shall ensure that all the type of energy that the System or equipment utilizes, shall understand the hazards of the energy, and shall know the methods to control the energy. In cases where complex lockout or multiple energy sources are involved the Person InCharge/Shift In-Charge shall generate an energy source identification sketch (a computer generated, hand written or in any other form) to properly identify all energy sources. Field operator/Operation Engineer shall ensure the equipment is not in operation and shall select the local/remote selector switch to local/Off position. She/he shall provide required danger tag as per job requirement on the Local Control Switch (LCS) or other control device. Field Operator/Operation Engineer shall ensure that stored energy (such as that in springs, elevated machine members, rotating flywheels, hydraulic systems, and air, gas, steam, or water pressure, etc.) shall be dissipated or restrained by methods such as, but not necessarily limited to repositioning, blocking, draining, venting, bleeding down, etc. Field Operator/Operation Engineer shall use the energy source identification sketch wherever applicable, isolate all energy sources by operating the valve, or other energy-isolating device(s) so that the equipment is isolated from its energy source(s). (Refer Annexure – 2) for Guidelines for positive isolation and special precautions). All such energy isolation points shall be provided with lockout device (Hasp) After energy source(s) isolation, the equipment shall be cleared by purging / draining / depressurizing / decontaminating and ensuring that the equipment / line is totally free of hazardous material. Person In-Charge/Shift in-charge shall submit list of all applicable isolation points for isolation/de-energization. Operation Engineer shall identify energy source(s). All such energy isolation points shall be provided with lockout device (Hasp) with Lock and Danger tag (Refer Annexure –3). Simultaneously the Maintenance Engineer or Team Leader shall provide his lock on the Hasp and retain the key of the locks in his custody till the job is over. Refer Annexure –5 for recommended LOTO methods for electrica Person In-Charge/Shift in-Charge shall ensure that equipment containing radiation sources, are locked out & tagged out by RSO (Radiation Safety officer) or by authorized Person, in accordance with radiation source manufacturer’s lockout / tag out recommendations. The Maintenance Engineer or Team leader shall provide the lock on each of the field energy-isolating device, as per the energy source identification sketch, wherever applicable, and retain the key to the lock till the job is over. After ensuring that no Persons are exposed to any hazard, Field Operator/Operation Engineer as a check on having disconnected the machinery or equipment from the energy sources, the Operation Engineer, in presence of Maintenance Engineer or Team Leader, shall operate (TRY) the push button or other control device to make certain that the machinery or equipment will not operate. Danger tag (Refer Annexure-3) shall then be placed on LCS or other control device. After servicing or maintenance is completed, Maintenance Engineer or Team leader shall check that the equipment and the area around the equipment is cleared and equipment guards, Safety devices, etc. have been reinstalled, temporary ground removed and ready for intended operation. Maintenance Engineer or Team leader shall ensure that all Persons have safely moved out of the hazardous zone. Maintenance Engineer or Team leader shall verify that control devices are in “OFF” position. All blinds/ blocks, etc. shall be removed prior to removal of locks. Maintenance Engineer or Team leader shall remove all locks provided on lockout devices (Hasps) at the energy-isolating points, including electrical energy source and clear his/her ‘danger tags’. Field Operator/Operation Engineer shall check & inspect the integrity of the equipment and remove his/her danger tags’ The equipment is now normalized for restoration into operation as per Safe Operating Procedure (SOP). In situations where the energy sources are locked and tagged, and there is a need for temporary re-energizing for testing / taking trial of the equipment, machine or part thereof ; Permission shall be obtained from Shift In-Charge before temporary re-energization. The following points shall be mutually agreed upon between the Person in-Charge/Shift Incharge and the Executing Persons/ Team Leader. Additional precautions to be taken during the restoration of energy, duration of testing and re-isolation of energy. In all cases, the temporary removal of Lockout / Tag out devices shall include, but not necessarily limited to, the following steps: Person In-Charge/Shift In-Charge shall ensure that the area in the vicinity of the target equipment / machinery is cleared. Person In-Charge/Shift In-Charge shall ensure that all Persons inside the hazard zone are informed that equipment / machinery needs to be re-energized for testing / trial. After getting final clearance from executing Person/ Team Leader, the Person In-Charge/Shift In-Charge shall re-energies the equipment / machinery for testing / trial. After completion of testing / trial, ‘Operating Permit/ Permit-to-Work’ shall be cleared by the executing Person/ Team Leader. Person InCharge/Shift In-Charge shall de-energies the equipment / machinery. For complex situations (as judged by Person In-Charge/Shift Incharge) the Person In-Charge/Shift In-charge should ensure that a specific written procedure covering all of the above points is prepared and reviewed with all Persons involved in the testing. Person In-Charge/Shift In-Charge shall ensure that all Persons (all groups of persons in case multiple groups are working) on the job, safely clear the job to enable testing / trial and remove their lockout temporarily. LOTO Register (TPSMS/CSP/LOTO/001 /FORM/001) – Retention – One years Training of this procedure shall be covered as per Safety Training Need identified across divisions. .Initial Communication to be done through Corporate Communication, Email and subsequently shall be made available at safety portal at Sangam.
