Barricade tape

It acts as a minor impediment to prevent accidental entrance to that area or situation and as a result enhances general safety.

The tape is often wrapped and affixed as a visual warning sign and demarcation, for instance against entering a dangerous area, such as an industrial or commercial building site, a roadworks construction site or the scene of an accident[1] or a crime (for crime scene preservation), or against handling inoperative machinery or appliances.

The choice of colours of barricade tape depends on the contrast with its background, which in the case of the sky, can vary from black to white.

These are found in OSHA regulations 1910.22[2] and 1910.144[3][failed verification] and ANSI Z535.5-2007, Safety Tags and Barricade Tapes (for Temporary Hazards).

This includes where any of the following present a risk: These markings should be made up of alternating red and white or yellow and black stripes of equal size at a 45 degree angle.
