Legionella Risk Management

Creating a safer environment for your residents, employees, and visitors.

Meras partners with healthcare facilities across the state of California to create a complete and comprehensive Legionella Control Program that follows industry accepted guidelines set forth by CMS, ASHRAE, CDC, and OSHA.

WHAT IS LEGIONELLOSIS?

Legionellosis is a respiratory disease caused by Legionella bacteria. Sometimes the bacteria causes a serious type of pneumonia (lung infection) called Legionnaires’ disease. The bacteria can also cause a less serious infection called Pontiac fever that has symptoms similar to a mild case of the flu.

WHERE DOES IT COME FROM?

Outbreaks of Legionnaires’ disease are typically associated with contaminated large or complex water systems, like those found in hospitals, hotels, long-term care facilities, and even gyms. The most likely sources of infection include, but are not limited to, showers, cooling towers, decorative fountains, and hot tubs.

HOW IS IT CONTRACTED?

Legionella is transmitted through the inhalation or aspiration (water accidentally enters the lungs) of small water droplets containing the bacteria. The contaminated droplets can take the form of a mist or spray. During infection, the bacteria will invade lung cells and replicate intracellularly.

WHO IS AT RISK?

The people most at risk for contracting Legionnaires’ disease are those with weakened immune systems. People with diseases such as HIV/AIDS, cancer, or diabetes; those who are over the age of 65; and those who have recently undergone an organ transplant have a greater risk of infection. Also, those whose lungs are weakened due to smoking or chronic emphysema are at risk of infection after exposure to the bacterium.

ASHRAE® STANDARD 188P

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE®) develops standards that are accredited by the American Standard Institute (ANSI). The industry has adopted Standards 188P which is a standard practice pertaining to Legionella control. This standard lays out the foundation for what an effective Legionella control program should entail. This standard is heavily influenced by the HACCP structure and it shares all of its components with other entities such as ESGLI and WHO.
