Overall, the evidence reviews found that that there was a paucity of research that specifically evaluated the efficacy or effectiveness of interventions to reduce adverse health effects of wildfire smoke. However, this is an active area of research with new evidence becoming rapidly available. By combining existing and emerging evidence, BCCDC has been able to make general statements about effectiveness of interventions such as air cleaners and face masks. Public health practitioners can then use the evidence to support their own guidance at the regional or local level. These results were compiled and summarized in the “Guidance for BC Public Health Decision Makers During Smoke Events” which was published in September 2014 and several fact sheets that are updated every year. These documents describe the wildfire smoke hazard and identify the health effects that are associated with wildfire smoke exposure and the populations that are susceptible. They also provide BC-specific guidance about tools for situational awareness (smoke and health surveillance) and summarizes the evidence for effectiveness of intervention measures to protect public health. For example, they explore the use of cleaner air shelters as an adaptation measure to reduce exposure to particulate matter generated by wildfire smoke and provide temporary relief for community members during smoke events. Cleaner air shelters are areas, rooms, or buildings that reduce the indoor impacts of particulate matter generated by wildfire smoke. The objectives of cleaner are shelters are to limit outdoor air entering the indoor environment, avoid creating indoor air pollutants, and to filter indoor air.
