Creating a Spa Pool Control Scheme: Essential Elements for Safety

A written control scheme is a vital document that outlines how you manage the risks associated with your spa pool. It should be specific to your system and tailored to its unique characteristics, ensuring that all aspects of safety are covered [32]. This post will detail the key components of a control scheme based on the HSE guidance [9].

A good control scheme should be part of your Normal Operating Plan (NOP), which together with your Emergency Action Plan (EAP), makes up your Pool Safety Operating Procedure (PSOP) [9, 32]. This is a practical way to make sure all employees know what they must do and when.

Key Components of a Spa Pool Control Scheme

  • Spa Pool and Plant Details: Include an up-to-date schematic diagram of the spa pool and associated plant, showing all parts of the system including pipework, filtration, and water treatment components [9].
  • Safe Operating Procedures: Describe the correct and safe ways of operating the spa pool, including procedures for startup, normal use, and shutdown [9].
  • Control Methods and Precautions: Outline all methods and precautions taken to control the risks associated with the spa pool. This includes details on chemical disinfection, physical cleaning, and other maintenance activities [59].
  • Checks and Frequency: Specify the checks required to make sure the spa pool is operating safely, including the frequency at which these checks should occur [59]. These will be daily, weekly and monthly checks.
  • Remedial Actions: Describe the necessary actions that should be taken if monitoring reveals that control measures are not working effectively [59]. This may include shock dosing or shutting the spa down to fix the issue.
  • Information for Users: Provide clear information to users about the safe use of the spa, including guidelines on hygiene, bathing times, bather loads, and who may not use the spa [59].
  • Specific Factors to Consider: Your scheme must consider the following factors [59]:
    • Type, design, size and capacity of the spa pool.
    • Source and quality of water supply.
    • Type of dosing equipment.
    • Pipework and construction materials.
    • Type of filtration system.
    • Heat source and temperature.
    • Chemical dosing and storage.
    • Type of treatment to control microbial activity.
    • A method to control pH.
    • Cleaning regime.
    • Chemical and microbiological testing regime.
    • Susceptibility of users.
    • Intended use.
    • Water replacement frequency.
    • Actions for adverse monitoring results and criteria for closing the spa.

Why is a Written Control Scheme Necessary?

A written control scheme serves several important functions [9]:

  • Clarity: Provides a clear reference point for all personnel involved in the operation and maintenance of the spa pool [60].
  • Consistency: Ensures that the required procedures are followed consistently, reducing the chance of errors [60].
  • Compliance: Demonstrates that you are adhering to health and safety regulations and guidance, for example the HSG282, the Health and Safety Executives document on spa pool safety [6, 61].

Frequently Asked Questions (FAQs)

Where should the control scheme be kept?

The control scheme can be kept as written documents or stored electronically, but it must be accessible to employees and available for inspection by the enforcing authorities [9].

Does the control scheme need to be reviewed and updated?

Yes, the control scheme should be reviewed regularly to make sure it remains relevant and effective, especially if there are changes in the spa pool’s operation or if new information becomes available [33].

Is it ok to have multiple control schemes?

It is best practice to have one control scheme, but if you have multiple spa pools you might need individual control schemes for each one [32].

What should happen if the scheme is found to be ineffective?

If the scheme is not effective, immediate action should be taken to review it, and any deficiencies should be addressed. It is likely the spa will have to be closed until the issue is resolved [22, 23, 32].

How is the control scheme related to the risk assessment?

The control scheme is a direct output of the risk assessment and sets out in detail what you will do to control the risks identified [62].

By implementing a comprehensive written control scheme, you can make sure your spa pool is managed safely and effectively, protecting the health and wellbeing of all users.
