Legionnaires’ disease and property risk

Legionnaires’ disease and property risk

Legionella: What is it?

Water management programs

A managed, well-constructed water management program is the most effective way to help reduce the risk of Legionnaires’ disease and improve organizational safety performance for a facility or complex operation. Water systems present unique risk exposures and require a detailed analysis.

Danger zone: Legionella in your water system

Healthcare and hospitality facilities often serve the populations at highest risk for Legionnaires’ disease. These populations tend to span the entire age and health spectrum, while the facilities often have complex water systems, from eye washing stations to decorative fountains and hot tubs.

The Centers for Medicare and Medicaid Services (CMS) and the Centers for Disease Control and Prevention (CDC) consider it essential that hospitals and nursing homes have a water management program that is effective in limiting Legionella and other waterborne pathogens in the premise plumbing from growing and spreading in their facility.

We can help

Our risk assessment tool for Legionella in water systems is designed to help assess and mitigate the risk of Legionella and other waterborne bacteria in potable water systems to prevent cases and outbreaks of Legionnaires’ disease.

This important risk assessment tool can be used to audit your facilities’ water management program. Our risk control consultants use this tool to identify water system components or devices in your building where Legionella might thrive or be distributed to humans through aerosols or droplets.

Our assessment can help you

Evaluate and identify the potential for Legionella bacteria risk or sources of potential amplification in large or complex water systems in settings with at-risk populations, such as those in the healthcare and hospitality industries.

Identify the risk level and provide improvement opportunities for those high-risk areas where Legionella growth and amplification risk is greatest in the facility.
