use an antique extinguisher.
Particular caution is warranted with historical extinguishers that may contain hazardous chemicals. If the contents are unknown, the safest approach is to leave the container undisturbed and consult a qualified conservator or hazardous-materials professional when necessary.
For display purposes, keeping the artifact in a stable environment away from excessive heat, moisture, and direct sunlight can help protect its glass, metal, and labels. Gentle handling and appropriate conservation methods can preserve these objects without compromising their historical character.
