Aerosol into a bottle for an airbrush. The numbers that matter are temperatures.

What people are doing

Discharging a rattle can into a jar so the primer can go through an airbrush, usually to get a finer coat than the can gives. It is a well known technique in this hobby.

And it takes a solvent out of a pressurized can

Which is the whole safety question. The propellant leaves, the solvent stays, and what you are holding is an open container of something that was designed never to be open.

The classifications

"Extremely flammable" is a flashpoint "at or below 20 degrees F (-6.7 degrees C)". "Flammable" is "above 20 degrees F (-6.7 degrees C) and below 100 degrees F (37.8 degrees C)". "Combustible" is "at or above 100 degrees F (37.8 degrees C) to and including 150 degrees F (65.6 degrees C)".

Each by a named test

The method at 16 CFR 1500.43a. A flashpoint is a measured value from a specified apparatus, not an estimate from a safety data sheet read quickly.

Many lacquer primers are in the first band

Which is the one that carries the words extremely flammable. If you are selling a decanted primer, that classification drives the label, the storage and the shipping before any art materials question arises.

Shipping is where this usually stops

A flammable liquid in a glass bottle going through a parcel network is a hazardous materials shipment with its own packaging, marking and training requirements. That is a different body of law and it is not optional.

Decanting primer for your own use on your own bench is one thing. Putting it in a box and handing it to a carrier is a hazmat decision, and nothing on this shelf is a certified hazmat package.

For your own bench, the container still matters

Glass over PET, a liner the solvent will not dissolve, a closure that seals, and never a container that was holding something else. 133 glass containers on this shelf and the Boston round is the shape for it.

Static and vapor are real

Decanting a solvent generates vapor faster than people expect, which is a ventilation question and an ignition source question at the same time. This is the one craft in this property with an immediate hazard rather than a chronic one.

And the chronic one is still there

Solvent vapor is the exposure the art materials labeling is about. Both rulebooks apply to the same jar: flammability for the immediate risk, chronic hazard labeling for the long one.

15 U.S.C. 1277, the Labeling of Hazardous Art Materials Act. Subsection (a) makes the labeling requirements of ASTM D-4236 "deemed to be a regulation issued by the Commission under section 1262(b) of this title". (b)(1) defines an art material as "Any substance marketed or represented by the producer or repackager as suitable for use in any phase of the creation of any work of visual or graphic art of any medium", excluding economic poisons under FIFRA and drugs, devices or cosmetics under the FFDCA. (b)(2) "applies to art materials intended for users of any age". (b)(5) requires the label of an art material needing chronic hazard labeling to carry "the name and address of the producer or repackager of the art materials and an appropriate telephone number and a statement signifying that such art materials are inappropriate for use by children". (b)(6) requires new hazard information to be "incorporated into the labels of such art materials that are manufactured after 12 months from the date of discovery". law.cornell.edu

Written from 15 U.S.C. 1277, 16 CFR 1500.14(b)(8) and 16 CFR 1500.3(c)(6), and from the catalog as it stood on 18 October 2026. Where a requirement turns on a determination the Commission makes rather than on a fixed rule, this property says so. Nothing here is a toxicological review, which is the one thing in this area that cannot be done from a document.
