Bio Hazard Warning Sign

US Army BIO Marker

This is a US Army biological hazard warning sign: an inverted blue triangle with a red border and red BIO lettering, made to mark a biological hazard so it can be identified at a glance. The face is reflective, so it shows up when headlights or a flashlight hit it. It is issued military marking gear, and it suits collectors of NBC (nuclear, biological, chemical) equipment, reenactors and anyone setting up a training lane or display.

Features

• Issued By The US Army — This is original government-issue marking equipment, not a commercial safety sign.
• Inverted Triangle Shape — The point-down triangle is the shape used for this kind of hazard marker, and it reads differently from a standard road sign at a distance.
• Blue Field With Red BIO Lettering — The blue background and red text identify the hazard as biological.
• Red Inner Border — A red band runs inside all three edges, framing the lettering and sharpening the outline.
• Reflective Face — The sheeting has a visible diamond pattern of tiny reflectors that bounce light back toward its source, so the sign stays readable in low light.
• Vinyl Construction — The sign is vinyl, so it is light and flexible enough to pack flat or hang without a rigid backing.
• Three Mounting Holes — Pre-punched holes along the top edge let you hang the sign from a stake, wire, cord or wall with ties or screws.

Original Issue Marking

The sign belongs to the Army's hazard marking equipment, which troops used to post warnings around contaminated ground. Its colors, lettering and reflective vinyl are original to the issued item, which matters to collectors building an NBC display and to reenactors who want genuine kit. The top-edge holes make it simple to hang on a fence line, in a training area or on a wall.
