Which guide to read first
If you are buying, read IBC tote dimensions and rebottled or reconditioned. If you have a pile, read RCRA empty and reading the UN plate. If you are a grower, start with food-grade history and drip irrigation. If you are catching rain, read rain barrels and California law and mosquitoes.
Every guide that cites a rule links the rule. Rules change and your facts may differ, so treat the guide as the question to ask and the source as the answer. The terms page says the same thing in two sentences.

Questions people ask
Are the guides legal advice?
No. They summarize published sources and say where to read them. Your permit, carrier and local authority decide your case.
