Firm Fined Following Legionnaires' Disease Outbreak: Ensuring Public Health and Safety

A plastics manufacturing company in West Bromwich has faced fines after a Legionnaires' disease outbreak put workers and the public at risk of infection. The Health and Safety Executive (HSE) investigated Riaar Plastics Limited following infections in September 2020, resulting in serious health implications for affected individuals. This incident sheds light on the critical importance of effectively managing the risk of Legionella bacteria and maintaining proper safety measures.


During September 2020, five individuals contracted Legionnaires' disease, a potentially life-threatening lung infection, from the vicinity of Riaar Plastics Limited. One person's condition became so severe that they required intensive care and ventilator support. The HSE investigation revealed that the water-cooling towers and pipes at the company's Black Lake site were in an alarmingly poor condition, allowing Legionella bacteria to flourish and posing significant health risks to employees and the public.

Legal Consequences: Riaar Plastics Limited pleaded guilty to breaching Section 2(1) and 3(1) of the Health and Safety at Work Act 1974. As a result, the company was fined £50,000 and ordered to pay £11,000 in costs by the Birmingham Magistrates' Court on 2nd June 2023. The severity of the fine reflects the gravity of the failures to manage the risk of Legionella bacteria effectively.

The Importance of Proactive Management: HSE principal inspector Jenny Skeldon, leading the prosecution, emphasized the deplorable condition of the cooling towers at the site, citing it as the worst she had ever seen. The extreme risk of Legionella exposure to employees, visitors, neighboring premises, and the public was evident. Legionnaires' disease can result in fatalities or serious illnesses if water cooling systems are not managed diligently. Skeldon stressed the importance of proactive risk management, highlighting the existence of well-publicized and simple precautions that, if followed, can ensure effective control of Legionella risks.

The fines imposed on Riaar Plastics Limited serve as a reminder that the health and safety of employees and the public must be given the utmost priority. The Legionnaires' disease outbreak and subsequent investigation underscore the need for companies to effectively manage the risk of Legionella bacteria. Employers must maintain proper maintenance, regular inspections, and implement necessary safety measures for water-cooling towers and systems. By adhering to recommended guidelines, businesses can safeguard public health, prevent potential outbreaks, and mitigate severe consequences. It is crucial for companies to learn from this incident and demonstrate their commitment to maintaining a safe working environment for all.
