Shirley Zylstra, of USFS Missoula Technical Development Center (fs.fed.us/eng/techdev/mtdc.htm), gave a talk and demonstration on the properties of aerial retardant, foams and gels along with tips on improving effectiveness. She presented this at two different sessions, in Anchorage on Feb. 10th and in Fairbanks on Feb. 11th. She included some information on toxicity of new vs. older long-term retardants used in Alaska, video clips, and demonstrations (which our meeting format software unfortunately failed to record for the Fairbanks session). This might be good material for basic firefighter classes as well as for fire resource advisors like wildlife and fisheries biologists.
