2.3 Chemical Control:

2.3.1 New Chemicals:

2 3 1 6 If not provided by the manufacturer, expiration dates will be determined from the chemical composition and reactivity information provided in the SDS

2 3 1 7 If a reagent, chemical, standard, media, or other substance is used up, the consumed by date must be documented in LF2021 Stock Chemical Logbook

2 3 2 Chemical Handling:

2 3 2 1 Only personnel that have been trained to properly handle hazardous chemicals should use them Both hands are required when picking up and transporting large jugs of chemicals If a chemical is too large or difficult to handle, use a cart, hand-truck or ask a fellow employee for help.
