After any storm like Frances, the two sounds you hear most are chain saws and the drone of generators. I bought a new chain saw Thursday night. Al with a power tool is a frightening thing, but Al with a CHAIN SAW -- that is a sight to see. This is a warning from one chain saw expert: The chain saw is the most dangerous hand tool that can be purchased on the open market. It requires no license and no training to own or operate it. An overall average of 40,000 injuries and deaths occur annually in the U.S. This figure is just the "reported" accidents given by hospitals willing or able to furnish the information. That figure does not include out-patient visits to the doctor. Most chain saw accidents are preventable. The only answer to reducing these accidents is proper training and knowledge with a lot of time using a saw -- which is experience. You can gain experience the hard way and have the scars to prove it or you can do a little preventative reading. (More resources) The U.S. Consumer Product Safety Commission says: There were over 28,500 chain saw injuries in 1999. More than 36 percent were injuries to the legs and knees. The average chainsaw injury requires 110 stitches and the average medical cost was $5,600 in 1989. Data according to The Davis Garvin Agency, an insurance underwriter specializing in loggers insurance. In 2000, corresponding costs can be estimated to be over $12,000. Medical costs for chainsaw injuries based on these facts amount to about $350 million per year.
