b. Receiving shipments Request safety data sheets for all chemicals being purchased. Understand proper handling, storage and disposal before ordering chemicals. Inspect chemical containers when they arrive. Open shipping boxes and styrofoam outer containers when chemical products arrive. This allows you to see if containers or contents have been damaged in shipping. Return even slightly damaged new containers for refund and replacement. c. Carcinogens, reproductive toxins or highly acute toxins are not allowed in middle school or high school laboratories in this school district without written approval of the Safety Program Manager or Chemical Hygiene Officer. Many of these compounds are on the Restricted Chemicals List. Carcinogenic metals include chromates, dichromates, cadmium compounds, cobalt compounds, and nickel compounds. Reproductive toxins include lead compounds, mercury compounds, bromates and the carcinogenic metals. Minimize the number, variety, and amount of these compounds in storage. Purchase as prediluted solutions if possible and only handle them in the fume hood if dusts or vapors could be released. Hazard identification Properly label laboratory chemicals to identify any hazards associated with them. a. Container labels Labels on incoming containers of hazardous chemicals must not be removed or defaced. Do not open unlabeled bottles of chemicals. Ask laboratory staff if they know what is stored in unlabeled containers. Dispose of unknown chemical compounds promptly as outlined in Section 12. Waste Disposal. When dispensing chemicals from one container to another, label the new container with the chemical’s name and hazards. Label all secondary containers in this manner unless they are intended for immediate use by the person who dispensed the chemicals. Label reusable pipettes with the chemical formula of the solution they contain. Return pipettes to a storage container that is labeled with the chemical’s name, formula and hazards. b. Safety data sheets Maintain safety data sheets received with incoming shipments of hazardous chemicals and make them readily available to staff and students. By mid-2016, safety data sheets must be provided that follow the Globally Harmonized System for Classification and Labeling of Chemicals (GHS). GHS safety data sheets have 16 sections, hazard pictograms, hazard statements, and precautionary statements.
