2 Copyright © 2013: Total Lockout (Safety) Ltd, Braintree, Essex, CM7 2YW – Website: I want to talk to you about worker safety!! Every year, numerous Alcoa workers are injured so badly that they miss a day of work. Our safety record is better than the general workforce, especially considering that our employees work with metals that are 1500 degrees and we have machines that can rip a man’s arm off. But it’s not good enough. I intend to make Alcoa the safest company in America. I intend to go for zero injuries October 1987 Paul O’Neill – CEO, Alcoa Source: “Is this the best CEO speech ever..?

4 Copyright © 2013: Total Lockout (Safety) Ltd, Braintree, Essex, CM7 2YW – Website: Why should we be concerned about LOTO? HSE Statistics 2011/12 – 173 workers killed at work – 111,000 injuries to employees under RIDDOR Mostly manual handling, slips and trips, falls from height. However………

5 Copyright © 2013: Total Lockout (Safety) Ltd, Braintree, Essex, CM7 2YW – Website: Why is LOTOTO important Man dragged in to a wood chipper during landscaping job! – While attempting to clear a blockage with his feet, he became entangled and was drawn into the machine. Prosecution: Lack of adequate training and risk awareness. Father of 3 pinned by a moving milk machine” – While carrying out routine maintenance on a container loading machine, it was somehow activated, pinning him inside. Prosecution: Failure to isolate.

6 Copyright © 2013: Total Lockout (Safety) Ltd, Braintree, Essex, CM7 2YW – Website: Three sub-contractors from a specialist engineering company undertaking maintenance work were drenched in a liquid jet of caustic soda when repairing a valve on a line running from a detergent tank. Up to 6,000 litres of the chemical spilled out from the container. One worker was temporarily blinded and one of his colleagues suffered 25 per cent burns left him with scars and continuing sensitivity, making it difficult for him to tolerate heat. The third man suffered minor skin burns and irritation to his eyes. The men had not been given adequate instructions or appropriate personal protective equipment. The company employing the men had not managed their contractors properly or carried out suitable risk assessments for the work that they had been asked to do.

7 Copyright © 2013: Total Lockout (Safety) Ltd, Braintree, Essex, CM7 2YW – Website: Two electricians suffered life-threatening injuries when they were engulfed by a fireball at a factory as they were about to clean debris from a damaged fuse box. One of the electricians is still undergoing treatment for his burns, nearly five years on, and will never be able to return to work. There had been a fire in the fuse box during the previous afternoon but live cables had been routed through it so that the cooling equipment at the factory could continue to operate. This meant the company avoided having to shut down the plant for 36 hours. A suitable risk assessment had not been carried out for the work and management at the company had allowed the work to go ahead without the electricity supply being isolated, even though this went against their own work procedures.

8 Copyright © 2013: Total Lockout (Safety) Ltd, Braintree, Essex, CM7 2YW – Website: An employee lost an arm at a giant industrial auger as he was carrying out repairs. He initially attempted a repair with the electrical power to the auger incorrectly isolated and without completing the permits for work required by company policy. The repair failed, so he attempted another repair the following day. However, both he and his supervisor failed to check that the power had been isolated, in breach of company procedures. When the supervisor accidentally activated the machine, his colleague's arm was removed above the elbow. Although the facilities to correctly isolate the machines were available, and the worker’s employer had trained its workforce in safety, it failed to provide the injured man with initial training or any additional information about the equipment he was working on or about company procedures. In addition, the plant manager did not supervise work correctly, which meant company permits to work were frequently not completed

9 Copyright © 2013: Total Lockout (Safety) Ltd, Braintree, Essex, CM7 2YW – Website: Judge Slates engineering firm for shambolic safety.... Engineering Firm fined £300k after investigation uncovers repeated failings that put employees at risk of death for several years. Isolation valve jammed while closing. Maintenance worker crushed when stored energy caused the valve to suddenly closed. HSE Investigation reveals ineffective isolation procedure.

11 Copyright © 2013: Total Lockout (Safety) Ltd, Braintree, Essex, CM7 2YW – Website: In summary... A safe method to work on machinery, equipment and other energy sources. The placement of a lockout device on an energy isolating device and the equipment being controlled cannot be operated until the lockout device is removed.

12 Copyright © 2013: Total Lockout (Safety) Ltd, Braintree, Essex, CM7 2YW – Website: What energy sources present a risk? Mechanical Hydraulic/Pneumatic Electrical Flow i.e. liquid/gas

13 Copyright © 2013: Total Lockout (Safety) Ltd, Braintree, Essex, CM7 2YW – Website: Also consider… Kinetic energy - moving/spinning shafts, inertia Springs Chemicals and Acids Asphyxiants Radiation – X-Ray, ionizing, lasers, microwave, RF Thermal – steam, cryogens

17 Copyright © 2013: Total Lockout (Safety) Ltd, Braintree, Essex, CM7 2YW – Website: Legal references…cont’d Provision & Use of Work Equipment Regulations (1998) 278: If work on isolated equipment is being done by more than one person, it may be necessary to provide a locking device with multiple locks and keys. Each will have their own lock or key, and all locks have to be taken off before the isolating device can be removed. Keys should not be passed to anyone other than the nominated personnel and should not be interchanged between nominated people. aka: Group Lockout

27 "Creating Practical Workplace Systems" Considerations for Effective Isolation Systems Sites should appoint a standout accountable representative, supported by a steering committee. Define the responsibilities and accountabilities of the persons performing isolations. Establish the training and competency requirements for permit issuers, permit holders and persons performing isolations. Ensure hazards associated with the planned activity are identified, appropriate mitigations documented and the work is authorised by a responsible person. Define isolation design criteria and process.

28 Copyright © 2013: Total Lockout (Safety) Ltd, Braintree, Essex, CM7 2YW – Website: "Creating Practical Workplace Systems" Define the controls which apply to personnel accessing machinery that may start and stop automatically or by instruction from a remote location. Control and approve any software overrides, hard- wire bridging or interlock bypassing. Control isolations which span one or more shift handovers. Identify any points of isolation and provide personnel performing the work with unique, secure, control of the point of isolation. Considerations for Effective Isolation Systems

29 Copyright © 2013: Total Lockout (Safety) Ltd, Braintree, Essex, CM7 2YW – Website: "Creating Practical Workplace Systems" Define how a competent person in ensuring safe isolation is achieved before commencing work. Determine the actions required if there is any doubt safe isolation was achieved. Manage isolations for interacting and/or simultaneous activities and where there is potential for multiple sources of energy (e.g. work on electrical ring feed systems). Develop systems to manage the isolation of HSE critical systems.

30 Copyright © 2013: Total Lockout (Safety) Ltd, Braintree, Essex, CM7 2YW – Website: "Creating Practical Workplace Systems" Manage changes which may affect the scope of the permit-to-work and/or the isolation standard(s) required, including changes to planned tasks and the action to be taken by the permit- holder in response to an emergency. Verify isolated equipment/plant is returned to a safe operating condition before it is brought back into service. Scheduled auditing/reviewing of the system, regularly analysing audit findings.
