I saw this on another board... thought I'd bring it over here to emphasize how one little slip can be dangerous.
01.16 USA Tampa, FL. A man received severe chemical burns when preparing to clean the tiled roof of a house in Hunter's Green, one of New Tampa's gated golf course communities. The man, who owns a pressure-washing company, climbed a ladder with a pressurised container of bleach and water, which exploded when he set it down, blowing a 750mm hole through the roof. Investigators later said the man poured chlorine [probably hypochlorite solution] and water into the container, which had previously been used to apply an acid wash. The container had not been properly rinsed, and the resulting chemical reaction caused the explosion.
