I'm looking for others for guidance (preferably written) on how you handle moving chemicals in passenger elevators. Consider a building 7 story building (plus a basement and sub-basement) with three elevators, none of them with local control, with a chemical stores and other receiving takes place in the "basement" (the basement level has an outside entrance). Or, a research building that only has one passenger elevator that services a 9 story building with research labs on multiple floors.
In particular, I'm interested if you have written policies, and have successfully implemented them in busy buildings, on restrictions on what time of day to transport, maximum amounts you allow transported, and under what conditions you routinely exclude other passengers from the elevator.
Although I am most interested in chemicals carried by hand or on a (sturdy) cart, I would also be interested if you have specific policies on elevators and "bulk" chemicals on a large flatbed cart or pallet, cryogenic liquids, or gas cylinders.
Feel free to post them here or send them to me directly (I can summarize what I receive directly if there is interest).
