I bought a Steel City blower at the Charlotte show. I decided to ceiling mount in the garage/shop. I have a truss system that is 24" in center and built some bracing to hold the weight. When I was checking the fit I stood on the floored part but managed to loose my footing. I'm 65 and have always been safety concious. 23 Years in the Navy taught me that. Ten feet later I was on the concrete floor and crawling to the phone to call 911. I spent 27 days in the hospital and rehab before I could get home. I am wheelchair bound unitl July. I won't share all the details but I broke a few bones and the hospital bill alone is $35,000! Lesson learned.....we can never be too safety concious! I am very blessed to even be alive and cannot wait to get back into the sawdust!
