The working parts of a building and a jobsite. PPE decals (hard hat, eye protection, hearing protection) go at the doors where the rule starts; hazard warning labels mark high voltage, flammable, compressed gas and biohazard points; fire and AED decals show where the extinguisher and the defibrillator live. Warehouse dock door numbers let drivers find the right door from the yard, and construction site decals carry the site rules and the general contractor's name at the gate. Fleet asset tags are the small numbered labels that let a shop track tools, trailers and equipment without a label printer. These are cut in the standard safety colors and sizes so they read from where a worker stands, and they go on painted steel, block, glass and most plastics.
