ASHRAEGuideline 44P, Protecting Building Occupants from Smoke During Wildfire and Prescribed
Burn Events, will provide HVAC and building measures to minimize occupant exposures
and health impacts from smoke during wildfire and prescribed burn smoke events. This
column summarizes the planning framework for Guideline 44P, which is being shared
by the guideline committee to provide immediate information on this pressing issue
while the committee continues work on the complete guideline.
The planning framework includes information
for building managers on developing their Smoke
Readiness Plan, preparing for smoke events by having
supplies on hand and testing procedures in advance,
and knowing when and how to implement measures in
their plans. The document, " Planning Framework for

occurred, burning more than 10 million acres
(4 million ha).1 Increasing numbers of wildfires and
large numbers of people living at wildland-urban interfaces makes protecting building occupants from smoke
critically important. Wildfire smoke is composed of fine
particulate matter (PM2.5, particles less than 2.5 m
in diameter) and gases. Although wildfire smoke contains multiple contaminants, this document focuses
on controlling exposure to PM2.5. Breathing high concentrations of these pollutants can cause respiratory
and cardiovascular health effects, especially for those
