Hogs, Jogs, Aprons and Packages: Test Your OSHA Vocabulary

To most people, an apron is a simple garment worn over the front of the body to protect one’s clothes when cooking. But in the world of Occupational Safety and Health Administration regulations, a common term like ‘apron’ can mean something else entirely. According to construction industry regulation 1926.606, under Subpart O: Motor Vehicles, Mechanized Equipment, and Marine Operations, an apron is “The area along the waterfront edge of the pier or wharf.”

On the next page you will find 10 common terms and their everyday definitions, and then next to that, their very different OSHA definitions. Can you match the letter of the common term with the number of its OSHA definition? The OSHA definitions and the standards to which they relate are taken from MANCOMM’s OSHA Dictionary, a one-of-a-kind book containing all the terms and definitions from the 29 Code of Federal Regulations (CFR) OSHA parts 1903, 1904, 1910, and 1926 (Inspections, Recordkeeping, General Industry and Construction).

If you get at least seven right, consider yourself exceptionally well-versed in OSHA matters—and give yourself a pat on the back if you can cite the standards to which the OSHA definitions apply.
