How dangerous is an overweight foam Spa Cover? Recently a friend was checking the chemicals in his spa. Rather than attempting removing the entire spa cover, he decided to just lift one side enough to get at the water long enough to get a sample. He bent over and supporting the heavy cover with his left arm while attempting to fill a sampling bottle with water from the spa to check the chemical content, and total alkalinity.

As he leaned over further, the weight of the water logged spa cover dislocated his left shoulder and allowed the cover to hit him on the back knocking him into the spa. Article Source: http://EzineArticles.com/1122897. Overweight Spa Covers
