The use of alkaline electrocleaners will result in the evolution of hydrogen and oxygen. Tanks should be well vented to remove these gases. Foam blankets on electrocleaners should be sufficient to prevent misting without excessive accumulation of hydrogen and oxygen. Disconnect current prior to removing work from electrocleaning tanks to prevent hydrogen explosions. Personnel using, handling, or working in areas where exposure to alkaline cleaners is possible must wear alkaline-resistant personal protection consisting of safety goggles, face shield, gloves, apron, and boots. Respiratory protection should be worn when dust or mist is a problem. Neutral Cleaners Although the destructive effect of neutral cleaners on body tissues may be minimal, in many cases these cleaners are used hot and the possibility of thermal burns from splashing may exist. Additions to working solutions should be made slowly and cautiously in a controlled manner to prevent splashing. Additions should only be made to cool solutions (<100oF). Equipment A preventive maintenance schedule should be implemented for the inspection and repair of defective cleaning equipment. Hoist systems, exhaust systems, heating systems, and tank systems should be inspected on a routine basis for proper function and equipment integrity. Worn, corroded, or damaged equipment should be repaired or replaced upon discovery. General 1.Never work alone when working with chemicals. 2.Read and understand Material Safety Data Sheets, technical bulletins, and drum labels for the materials you handle and work with. 3.Always wear the personal protective equipment specified in the Material Safety Data Sheets, technical bulletins, or drum labels. 4.If you are injured notify the appropriate personnel and get medical attention as soon as possible. 5.If a spill occurs notify the individuals in your facility who are properly trained to respond to chemical spills. 59
