This year there will be many submerged suction outlet covers being replaced. I heard of one incident where a technician removed debri from one of a dual drain system and was held in place by the suction restarting and no cover in place as it had broken. I have not confirmed this story but it does present a real life situation that could occur. We all know you cannot fix stupid but someone may not be stupid just not educated as to the hazard that could occur by not shutting down the system before doing repair work around such an outlet. What steps are you taking to ensure that those that work with you or for you are taking necessary precautions. What education are you providing for your CPO's and your customers with CPO's? Do you think your local trade organization (APSP, FPSA etc.) should have special meetings on such?
