## Why an instruction sheet is in a propaganda archive

The archive is candid about it: this is mainly an instruction sheet, and the technique is faint. The one tag is fear appeal, for the "THIS EXTINGUISHER IS FOR YOUR PROTECTION" line and the stress on "NOW." The issuer is the U.S. War Department, classed as military; the audience is "Own forces"; the purpose is "Warn or inform." The themes are war and the military, and science and technology, and the event is recorded as the period after the Second World War.

The sheet earns its place as a baseline. It tells the reader what the device is for, what not to use it on, how to work it, and what to report if it is empty, damaged or tampered with. A blank line is left for a phone number to call. Next to the persuasion sheets elsewhere on this site, it asks for four steps in order.

## The rest of the series

The archive holds six more "Learn to use it now" records from 1946, for carbon dioxide, carbon tetrachloride (two records), foam, foam pump tank, and water pump tank extinguishers. This page covers the soda-acid sheet as the example of the set. For a War Department poster of the same period that does try to persuade, see Something Money Can't Buy, the 1945 sheet on civilian service ribbons. The civil defense hub covers atomic-age messaging from 1945 to 1969.
