ASHRAE Standard 188 is a standard set out by the American Society of Heating, Refrigerating and Air Conditioning Engineers regarding legionella risks in a wide range of different buildings.

The standard is aimed at building owners and managers that operate buildings in the criteria outlined by Standard 188. As part of the standard, building operators have greater responsibility in eliminating the risk of legionella.

Who does ASHRAE Standard 188 affect?

Not all buildings are affected by ASHRAE Standard 188. The standard only applies to building managers and property owners that operate buildings that are targeted by the new standard.

Buildings subject to Standard 188 must fit any of the following descriptions:

  • 10 or more floors, including basements and below-grade floors
  • Occupied by people that are potentially immune-compromised
  • Contains a whirlpool or spa on the building’s premises
  • Contains a device that generates aerosol, such as a fountain
  • Contains several residential units supplied by one water heater
  • Contains an NVAC system with cooling provided by a cooling tower
  • Has a total halogen concentration of 0.5 mg/L of Cl2 or more in potable water

Effects of ASHRAE 188 for building managers and owners

ASHRAE Standard 188 is of interest for building owners and managers. Standard 188 puts greater levels of responsibility for preventing legionella on owners and managers.

Since the standards put a greater level of responsibility on owners and managers, many commercial and residential building managers will need to make preventing legionella a higher priority.

Consequences for managers and owners that fail to meet the standard

Legionella is regarded as a known safety and health hazard, according to OSHA – the Occupational Health and Safety Administration. This means that building managers and owners are required, by law to protect occupants from this hazard.

Under ASHRAE Standard 188, businesses face a significantly higher risk of being found negligent in civil litigation. This makes preventing legionella a significantly higher priority for building owners and managers.

How can building managers and owners comply with ASHRAE Standard 188?

Since the ASHRAE Standard 188 makes building owners and managers significantly more responsible for preventing legionella safety and health risks, it’s important to take additional safety precautions.

Building owners and managers can comply with Standard 188 and reduce the risk of legionella by ensuring their water systems are properly designed and maintained to reduce health risks and perform regular testing for legionella bacteria.

Managers and owners should also make use of Hazard Analysis and Critical Control Point systems to prevent serious legionella risks from forming and control the risk of legionella health issues.
