A chemical-resistance shelf: two materials, eight forms, and the liner is the whole decision.

The shelf, measured

One hundred and ninety-one containers from 100 to 4,731 mL with 236 closures. By material 149 HDPE and 42 glass, and nothing else. The dominant necks are 38-400 at 46 and 24-410 at 43, then 28-400 at 21 and 28-410 at 16.

The forms

38 packers, 36 Boston rounds, 34 cylinder rounds, 14 cosmo and bullet, 12 F-style jugs, 10 specialty bottles, 8 round tubs and 7 spray and trigger bottles. That spans a 100 mL reagent bottle and a gallon jug from one shelf.

Only two materials, deliberately

Nothing here is PET, which is the right exclusion for solvent-borne products. HDPE covers a wide span of acids, bases and solvents, and glass covers the rest.

Color, and what it is for

83 white, 51 natural, 16 black, 16 clear and 14 amber. Natural lets a user see the level, white gives the best surface for a label carrying six required elements, and amber protects a light-sensitive reagent.

White matters more here than usual

Because the label is doing regulatory work and has to be prominently displayed and legible. 83 white containers is the largest group on this shelf and that is a useful coincidence.

The closures

159 continuous thread, 27 spouted, 19 flip top, 7 phenolic and 7 buttress, with tub and dome lids behind them. By liner 80 carry an HIS induction-seal liner and 37 pressure-sensitive.

The 7 phenolics are worth singling out

Thermoset caps, historically the solvent answer, and a small specific set on a shelf where most of the closures are polypropylene. For an aggressive solvent they are the first thing to ask about.

References

29 CFR 1910.1200(f), Labels and other forms of warning. Paragraph (f)(1) lists the six required elements on a shipped container: product identifier, signal word, hazard statements, pictograms, precautionary statements, and the name, address and telephone number of the responsible party. (f)(2) requires them to accord with Appendix C for each hazard class and category, prominently displayed and in English; (f)(3) requires the signal word, hazard statements and pictograms to be located together; (f)(5) requires the label not to conflict with the DOT transport rules. law.cornell.edu

Written from federal regulation and from measured catalog data, not from a plant floor. Hazard classification is a technical exercise with appendices behind it, and nothing here classifies a chemical or writes a label. The point of these pages is to show which regime applies and what it asks for.
