Gas Hazard Warning Sign

Army Gas Warning Marker

This is a US Army gas hazard warning sign: an inverted yellow triangle with a red border and the word GAS in bold red capitals. The layout matches the standard military marker for an area contaminated with chemical agents, built so troops can recognize the hazard at a glance and at a distance. Collectors of CBRN gear (chemical, biological, radiological and nuclear defense), reenactors and anyone dressing a display or workshop wall will find it a genuine piece of issued equipment.

Features

• US Army Issue — Originally issued government equipment, not a commercial novelty sign.
• Inverted Triangle Shape — The point-down triangle is the recognized outline for military chemical contamination markers.
• Red GAS Lettering — Large block capitals in red spell out the hazard so it reads clearly from across a field or room.
• Red Inner Border — A red stripe runs inside all three edges and frames the warning against the yellow face.
• Reflective Yellow Face — The surface carries a fine honeycomb texture of retroreflective sheeting, which bounces light back toward its source so the sign shows up under headlights or a flashlight.
• Vinyl Construction — Made from flexible vinyl that can be hung from a line or fixed to a flat surface.
• Three Mounting Holes — Pre-punched holes at both top corners and the center of the top edge accept cord, wire, screws or zip ties.

Original Specification

The colors and shape follow the military convention for marking chemical hazards: yellow for the background, red for the lettering and border, and a triangle so the marker reads as a warning before the text is legible. Because this sign was produced for the Army rather than for the gift market, it carries the authentic design that reproductions try to copy. Hang it from the three top holes for the orientation it was designed for.
