Template:US respirator topics/doc

In topics stretching as far as "respirator," it's easy for information to get lost, or not get read. Bit of a problem since respirators are quite consequential. This sidebar may help partially solve this. Not viewable on mobile. Use this template on large articles only.
 * Some people may not realize discussion of these topics are embedded into larger, more general articles.

This sidebar is planned to be used on these large articles:
 * Respirator - Disadvantages section
 * Self-contained breathing apparatus - lead, that's also why NFPA is here.
 * N95 respirator - History section
 * NIOSH air filtration rating - lead
 * NIOSH - Important regulatory authority.

As for colors, particulate only colors should be used, since most links are about biological particulates:
 * Purple analog for HEPA/P100
 * Teal analog for non-oil-resistant respirators. This has been replaced with the Wikipedia colors for headingstyle.

Of course, purple HEPA isn't the exact one used in the standard, having been modified slightly for readability.

Issues should be discussed on the template talk page.
