 Folding lockout hasp, allowing the use of up to six padlocks to secure a device. Lock Out, Tag Out (LOTO) is a safety procedure used in industry and research settings to ensure that dangerous machines are properly shut off and not able to be started up again prior to the completion of maintenance or repair work. It requires that hazardous energy sources be "isolated and rendered inoperative" before work is started on the equipment in question. The isolated power sources are then locked and a tag is placed on the lock identifying the worker who placed it. The worker then holds the key for the lock, ensuring that only he or she can remove the lock and start the machine. This prevents accidental startup of a machine while it is in a hazardous state or while a worker is in direct contact with it. Lockout-tagout is used across industries as a safe method of working on hazardous equipment and is mandated by law in some countries. Disconnecting or making safe the equipment involves the removal of all energy sources and is known as isolation. The steps necessary to isolate equipment are often documented in an isolation procedure or a lockout tagout procedure. The isolation procedure generally includes the following tasks: Announce shut off Identify the energy source(s) Isolate the energy source(s) Lock and tag the energy source(s) Prove that the equipment isolation is effective A common feature of these devices is their bright color, usually red, to increase visibility and allow workers to readily see if a device is isolated. Also, the devices are usually of such a design and construction to prevent it being removed with any moderate force - for example, an isolation device does not have to resist a chainsaw, but if an operator forcibly removes it, it will be immediately visible that it has been tampered with. To protect one or more circuit breakers in an electrical panel, a lockout-tagout device called the Panel Lockout can be used. It keeps the panel door locked and prevents the panel cover from being removed. The circuit breakers remain in the off position while electrical work is done. Site policies regarding lockout / tagout A site lockout / tagout policy will provide workers with an explanation of the safety goals of the policy, will identify steps required for a lockout / tagout, and will advise of the consequences of failure to carry out the policy.Richard A. Bolmen, Semiconductor Safety Handbook: Safety and Health in the Semiconductor Industry,William Andrew, 1998,, page 298 A documented lockout / tagout policy may be required by government regulations in some jurisdictions, for example in the United States for sites regulated by OSHA rules. Lockout-tagout in the US, has five required components to be fully compliant with OSHA law. The five components are: Lockout-Tagout Procedures (documentation) Lockout-Tagout Training (for authorized employees and affected employees) Lockout-Tagout Policy (often referred to as a program) Lockout-Tagout Devices and Locks Lockout-Tagout Auditing - Every 12 months, every procedure must be reviewed as well as a review of authorized employees UK There are a few instances across UK regulations that refer to ‘Lockout Tagout’ indirectly. The use of ‘Lockout Tagout’ is not currently enforced in the UK but has been proven to be best practice for multiple UK industries. There are citations within the PUWER regulations that argue the use of safety devices such as Lockout Tagout , however at no point do the regulations state this outright. But it does explain that ‘lockout devices’ should be used to enhance the safety of employees. So, it may not be written in black and white under English Regulations that Lockout Tagout should be used but the document does mention a ‘Hierarchy of measures’ for standardising safety procedures that are Lockout Tagout related but they are explained as a permanent fixture to any machine or tool. For instance one of the three measures mentioned is to ‘provide protection appliances (jigs, holders, push sticks)’. And as a wider assumption this could include LOTO devices but it doesn't specifically say that in the regulation. This part of the regulation is more about ensuring that the day to day workplace risks are assessed properly and thoroughly. However, in the same set of regulations, later on, it states that employers should ensure that all work equipment is accompanied by an appropriate way to isolate power/energy. Including an appropriate set of actions (and facilities) to turn the power back on without creating a potential hazard for other employees. This is more aligned with the American OSHA guidelines and practices and defines that the Lockout Tagout Safety movement is on the rise in the UK. In the EU, the guidelines are OSHA based and therefore pick up on American characteristics in its legislation, but it is 89/655 paragraph 2.14 that states that “every piece of equipment must be fitted with clearly visible devices with which it can be separated from every energy source” [EU Guidelines 89/655 (Paragraph 2.14)]. This indicates that all workplace machinery should be fitted with permanent LOTO solutions for easy and safe Lockout Tagout procedures.
