# Universal precautions

This varies by state

Licensing, waste and compensation rules are set by state. This page reflects https://www.osha.gov/laws-regs/regulations/standardnumber/1910/1910.1030 as of 2026-08-18. Verify with Universal precautions before relying on it.

The rule that all human blood and certain body fluids are treated as infectious, rather than only the ones that look like a risk. It is the operating assumption behind every procedure a trained crew follows.

## What kind of thing this is

Universal precautions is a rule with legal force in this field. This definition comes from a primary government source. Where the wording matters we quote the standard rather than paraphrase it, because paraphrase is where precision leaks out.

## Where you will meet it

This one shows up when you ask a company how it operates — in an exposure control plan, on a waste manifest, or in the paragraph of a state statute somebody quotes at you. It binds businesses rather than households, which is the distinction most often blurred when it is cited at a homeowner.

## Why the wording matters

This site defines terms in under forty words wherever it can, and attaches the practical consequence rather than leaving it implied. A definition that tells you what something is, without telling you what follows from it, is trivia at a moment when nobody has room for trivia.

General information, not legal or insurance advice. Rules and benefits vary by state and change. Verify with the agency listed.
