HSE ACoP L8: What Does It Stand For?

Managing the supply of water systems is essential to prevent Legionella bacteria. The Health and Safety Executive (HSE) provides two key guidelines: the Approved Code of Practice – ACoP L8 and the technical guidance document HSG274. This blog will cover the basics of these guidelines to build your understanding.

What is the ACoP L8?

ACOP L8 stands for the approved code of practice titled “Legionnaires’ disease: the control of legionella bacteria in water systems.” It provides practical advice on managing Legionella and adhering to regulations. This is the eighth edition, published in 2013. ACOP L8 gives guidance to businesses on legal requirements in relation to Legionella under:

• The Health and Safety at Work etc Act 1974
• The Control of Substances Hazardous to Health 2002
• The Management of Health and Safety at Work Regulations 1999

Business owners and landlords risk prosecution if they do not comply with this code. The Health & Safety Executive Board approves ACOPs with approval from the Secretary of State.

Who is ACoP L8 for?

ACOP L8 applies to any place where water is used or stored for business or other activities. This includes areas where inhaling water droplets could pose a Legionella risk. The guidance is for employers and those responsible for health and safety to help them comply with their legal duties related to Legionella.

What Guidance Does ACoP L8 Cover?

Approved Codes of Practice (ACOPs) offer preferred methods to help ensure regulatory compliance. ACOP L8 guidance focuses on several key areas: assessing Legionella risks, defining the role of the “responsible person,” creating a control scheme for Legionella, reviewing control measures, and outlining duties for those managing water systems. The ACOP L8 document contains two main parts: the code with legal status and additional guidance. ACOP L8 assists duty holders in conducting risk assessments, identifying key areas to focus on, and providing examples of control measures to reduce risks.

The Importance of ACoP L8: Control of Legionella Bacteria in Water Systems

ACOP L8 is crucial for legal compliance regarding health and safety responsibilities. If you face legal action for a breach of health and safety laws and haven’t followed ACOP L8, you must prove you’ve complied in another way. Business owners and directors should know ACOP L8 guidelines and have policies or procedures to demonstrate compliance. While it’s not mandatory, following ACOP L8 is usually enough to meet legal requirements for controlling Legionella.

Legal Requirements for Duty Holders

The duty holder must fulfil these legal obligations:

Identifying and assessing sources of risk

This involves checking if conditions support bacterial growth. For instance, bacteria thrive in water temperatures between 20–45 °C. Bacteria can spread through breathable droplets created by cooling towers, showers, and spa pools. People at risk might be exposed to these contaminated aerosols.

Preparing a scheme to prevent or control risk

The duty holder should create a written plan to prevent or control the risk of Legionella bacteria.

Implementing, managing and monitoring precautions

To keep control measures effective, it’s vital to regularly check systems and measures. Monitoring bacterial levels shows if you have microbiological control. Sampling for legionella also helps verify system control.

Keeping records of the precautions

Keeping records shows that your water systems are well-managed and controlled. These records protect you if questions or challenges arise. Without them, you are at risk.

Appointing a competent person as the “responsible person”

The person responsible for managing the daily control of premises for Legionella bacteria and Legionnaires’ disease.

Who Should be Appointed as the Responsible Person?

Anyone in the organisation can be named the responsible person if they have enough authority, skills, and knowledge about the business and Legionella risks. The HSE requires this person to complete specific Legionella training courses from a qualified provider to manage and control the risk of exposure to Legionella bacteria.

Do I Need to Complete a Legionella Risk Assessment?

Every man-made water system needs a Legionella Risk Assessment. As the duty holder, you must ensure a competent person carries out this assessment. This could be you, a colleague, or a consultancy service. The assessment identifies any reasonable risk of exposure and specifies Legionella risk management, showing that you have considered potential hazards and ways to prevent or control those risks. If your organisation has five or more employees, you must keep a written record of the assessment. Keeping a record is a good practice regardless of your organisation’s size.

ACoP L8 & HSG274

HSG274 provides detailed guidance to support ACoP L8. It offers information on water systems, their risks, control measures, and monitoring requirements. The document is split into three parts: Part 1 of HSG274 covers cooling towers and evaporative cooling systems, Part 2 focuses on hot and cold water systems, and Part 3 deals with other risk systems like spa pools and decorative water features. Further guidance on spa pools is available in HSG 282.

FAQs

What is an L8 qualification?

The Health and Safety Executive’s (HSE) ACOP L8 is the official code of practice. It provides clear guidance on how to control legionella bacteria in engineered water systems.

Is L8 a legal requirement?

Yes, following ACoP L8 is legally required. Not doing so can result in legal action. If you fail to adhere to ACOP L8 guidelines, inspectors may find you at fault during an investigation into Legionnaires’ disease cases. However, while following ACOP L8 typically ensures compliance, you may choose to adhere to the law in some other way, provided you can demonstrate effective Legionella control measures.

Is HSG274 a legal requirement?

The guidance in HSG274 is not mandatory except where specified. You can choose different actions, but following this guidance usually means you comply with the law. Health and safety inspectors may use this guidance when inspecting your premises.

What are some examples of controls covered in ACOP L8 to prevent Legionella bacteria?

Examples of controls in ACOP L8 regarding Legionella prevention include:

• Keeping water temperatures below 20°C or above 45°C to prevent the growth of Legionella bacteria
• Preventing water from becoming stagnant
• Reducing materials that harbour bacteria or provide nutrients for Legionella
• Ensuring the system and water remain clean
• Applying water treatment methods like chlorination or UV disinfection
