Pergunta anterior, trazer online e offline, neste processo algumas coisas são tão sérias que não devem ser deixadas ao acaso. Portanto, a utilização de uma chave real e de um processo para utilizar essa chave. Para segurança na reparação de grandes bombas ou bombas de petróleo, processamento e produtos químicos especialmente perigosos, existem livros de registo, assinaturas necessárias e apenas pessoas designadas podem bloquear ou desbloquear os vários dispositivos de segurança concebidos para evitar erros simples mas perigosos (o que os japoneses chamam Poke Yoke),

invision topic.....For very critical services to avoid poor operator choices or inadvertant operation of important safety related valving, some facilities will Lock Open and Lock Closed certain valves that should not ordinarily be in the alternate position. An example might be at the inlet to a PSV. The inlet and outlet valves could be locked open so that the operation of the PSV is not erroneously defeated. The valves could still be closed, but administrative procedures should be in place to ensure that the unit's safety was not compromised by this unusual valve operation.

hbr.org Shingo’s trans-idiotic design insight was poka-yoke — Japanese for “avoid mistakes.” In effect, Shingo looked for the simplest, cheapest, and surest way to eliminate foreseeable process errors. To make sure an assembler uses three screws, for example, package the screws in groups of three. The package is a poka-yoke device. Obvious? Perhaps. But “obvious” is often an underutilized and underappreciated asset. This goes well beyond “ounce-of-prevention vs. pound-of-cure'” clichés because sometimes ounces cost more than pounds and, more importantly, constantly looking for creative ways to minimize mistakes

marathon.refinery...9.7.6 When work must occur between an open shutter and the mounting ***vessel, employees
must use tools with handles to prevent passing a body part through the beam path.
9.7.7 The RSO will provide energy isolation for the sources as required.
The RSO has a group of Gold ***locks**** they will use and the key will remain under
the control for the RSO or other trained personnel. It will be included in the
Master Isolation List (MIL).
An Orange operations isolation lock will be placed on the radiation source, in
addition to the Gold RSO lock. The key to the orange lock will be placed in the
Owning Department’s Master Isolation lock box and the lockbox number
included on the MIL.

14.14 Equipment Isolation Locks - are locks assigned to the owning department for the purpose of
isolating equipment. These locks will be placed on breakers, valves, etc. and only one key will
operate each lock. Equipment isolation locks shall be standardized by color, shape or size

Lockout Policy:
The Control of Hazardous Energy
1. Purpose
This policy establishes requirements for the control of hazardous energy through the development and
implementation of hazardous energy-isolation Lock-Out and Tag-Out (LOTO) procedures.

tmb https://conect.online/blog/entenda-o-que-e-lockout-tagout-e-... O que é Lockout ?
A palavra inglesa “lockout” pode ser traduzida como “travamento”. Assim, esse processo pode ser entendido como uma forma de barrar ou impedir a exposição do colaborador à energias perigosas, evitando uma situação de risco.

A prática do Lockout evita que alguém acesse uma determinada área restrita inadvertidamente ou que ligue algum equipamento que não esteja preparado para ser utilizado. Ela também isola fontes de energia que podem queimar, cortar, prensar, eletrocutar ou lesar o colaborador.
