Before developing a Lockout Tagout (LOTO) Plan, it’s important to understand why LOTO matters.

Clear, documented lockout tagout procedures for each machine and energy source.

Lockout Tagout procedures protect workers from hazardous energy sources. When machinery is not safely isolated, the consequences range from minor injuries such as cuts or bruises, to life-changing harm including amputations, electric shocks and, at worst, fatalities.

LOTO is referenced within the Provision and Use of Work Equipment Regulations (PUWER), and when implemented effectively, it becomes a critical part of your machinery safety and overall risk management strategy.

What Should a LOTO Plan Include?

Every effective LOTO Plan has three core components:

1. Procedures for isolating equipment
2. Authorised personnel
3. Approved lockout devices

With these essential elements in place, you can begin operating a basic LOTO safety programme that can be developed and improved over time.

Where to Start

Begin with a walk-through of the workplace and assess equipment individually:

• Can LOTO procedures for each machine be easily located at point of use?
• Are authorised personnel available when machinery needs isolating?
• Are LOTO devices immediately accessible for standard isolation or in case of an emergency?

If the answer to any of these questions is unclear or inconsistent, that indicates a weakness in your Lockout Tagout system or even a lack of a Lockout Tagout System. Inconsistency increases the likelihood of mistakes and when hazardous energy is not controlled, the consequences can be severe. For LOTO to work consistently, preparation is key.

Conduct your own LOTO assessment across multiple areas. If you believe your procedures are robust, confirm whether every operator would answer these questions the same way. It only takes one person to skip or misunderstand a step for a serious incident to occur.

Understanding Your Site’s Requirements

Every workplace will require a different Lockout Tagout Plan depending on:

• The number and type of machines
• The range of hazardous energy sources present
• Site complexity and layout
• Workforce size and levels of training
• Before developing a full LOTO plan, you must understand and identify all hazardous energy sources. A single machine may have multiple isolation points.
• The key to compliant LOTO safety is accurate documentation.
• This information forms the foundation of a practical, compliant LOTO plan.
