Chemical Safety Many cleaners and sanitizers are corrosive or toxic compounds that must be handled in a safe manner. Chemicals should be handled and applied with all possible precautions to protect the workers who use them General guidelines for handling chemicals Material Safety Data Sheets describing potential hazards for hazardous chemicals must be filed and in a place that is accessible to all workers. In addition to MSDS sheets, keep a copy of the container label and technical service bulletins. Review them regularly for any changes that occur. Send copies of MSDS sheets to the emergency room of your local hospital. Post emergency numbers and the nearest Poison Control Center (1-800-222-1222) in a prominent location. If a chemical is swallowed, call for emergency help immediately. Do not induce vomiting unless instructed by a doctor. If there is contact to the skin or eyes, flush the area for 15 minutes and get medical help. Store chemicals in a cool, dry, place without sun. Keep them locked and allow access to authorized individuals only. When handling concentrate solutions, protect you hands and face by using safety glasses or face shields, wearing cuffed rubber gloves, and wearing long sleeved protective clothes. Prevent chemicals from reaching the hands and feet by cuffing rubber gloves and by not tucking pants inside boots. Do not mix materials using containers or scoops that are used for other products. Dangerous reactions can occur. When diluting sanitizers, always add concentrated sanitizer to water; not water to sanitizer. Adding water to a concentrated sanitizer may rapidly generate heat and splattering. Strong acids, alkalis, and concentrated chlorine solutions are highly corrosive and should not be sprayed in plants. Guidelines for specific types of chemicals Chlorinated products Mixing a chlorine sanitizer with acid generates deadly chlorine gas. Mixing sodium hypochlorite with quaternary ammonium compounds generates heat and nitrogen chloride (explosive). Chlorinated compounds react violently when combined with acids, alkalis, or ammonia. Do not mix these substances or allow contact in any way. Solid chlorine compounds are strong oxidizers and must be stored away from organic materials. Alkalis Many products such as caustic alkalis give off heat when mixed with water. Always add the chemical to the water. Never add the water to the chemical. Do not use strong alkalis on aluminum surfaces. Explosive hydrogen gas can be generated. Remove clothing contaminated with alkali immediately. Do not wear again until thoroughly washed. Discard shoes that are severely contaminated with alkali. Alkali spills can cause floors to become very slippery. Divert traffic in the affected area and flush away the chemical with cool water. Acid compounds Acid vapors can irritate skin, eyes, mucous membranes, and respiratory tract. If vapors or fumes are inhaled, seek fresh air immediately. Sodium hydroxide reacts with aluminum to form hydrogen gas which is explosive at a 4 or lower.
