Is Your Workplace at Risk for Legionella?
Understanding legionella risks in businesses mitigates against serious health issues, ensures compliance with UK Laws and brand protection.
Legionella bacteria are a serious health hazard that can thrive in commercial and industrial water systems if not properly managed. Inhalation of aerosolised water droplets containing Legionella can cause Legionnaires’ disease, a potentially fatal type of pneumonia.
For businesses, this is not just a health concern, it also brings legal, financial, and reputational risks.
Understanding legionella risks and mitigating these risks is essential for safeguarding the health of employees, customers, and visitors.
High-Risk Areas in Commercial Properties
Legionella bacteria flourish in warm, stagnant water, particularly in areas where water systems are not regularly cleaned, flushed, or maintained. Common high-risk areas in business premises include:
- Cooling Towers: Often part of HVAC systems, these require consistent maintenance and monitoring to prevent bacterial growth.
- Water Storage Tanks & Hot Water Systems: Poorly maintained systems with inconsistent temperatures are ideal for Legionella.
- Spa Pools & Decorative Fountains: These create aerosols that can easily spread contaminated water droplets into the air.
- Industrial & Manufacturing Facilities: Equipment using water or producing steam may inadvertently create warm, stagnant conditions.
- Hotels, Offices & Large Buildings: Complex plumbing networks can result in unused pipework and stagnant water pockets.
- Additional Sources: Includes humidifiers, air washers, emergency showers, misters, and indoor water features.
Regular monitoring and control of these systems are essential for Legionella prevention.
Legal Compliance & Employer Responsibilities
UK health and safety legislation places a legal duty on employers, landlords, and building managers to control Legionella risks.
Key regulations and guidance include:
- Health and Safety at Work Act 1974
- Control of Substances Hazardous to Health (COSHH) Regulations
- Approved Code of Practice (ACoP) L8
- HSG 274 – Technical guidance for Legionella control
- BS 8580-1:2019 – Legionella Risk Assessments
