TECHNICAL FIELD

Exemplary embodiments of the present invention are directed to novel safety devices. More particularly, exemplary embodiments of the present invention relate to devices for personal safety having high visibility, highly reflective, and luminescent features.

BACKGROUND OF THE ART

In developed countries, the construction industry represents six to nine percent of the gross domestic product. For example, in the 2015, the construction output of the United States was estimated to be approximately six hundred billion dollars. Thus, at any given time there are tens of thousands of ongoing construction projects. A major concern for any construction project is maintaining the safety of the workers and the public in and around the construction zone.

The Occupational Safety and Health Administration (OSHA) and the American National Standards Institute (ANSI) both provide regulations for the safety or workers and the public. One such area that both OSHA and ANSI provide regulations is the warning of individuals as to areas or situations containing a possible hazard. Such warnings serve to prevent accidental entrance to the areas containing possible hazards resulting in enhanced general safety.

One such method of warning is the use of barricade tape. Although both OSHA and ANSI provide regulations for barricade tape, there are many different types of barricade tape, including caution tape, hazard tape, traffic control device tape, police tape, firefighter tape, etc. The OSHA and ANSI both provide for color schemes to indicate the nature of the hazard (e.g., yellow-black tape for physical hazard, white-blue tape for defective machinery).

Another safety device governed by OSHA and ANSI is rebar caps. On any construction project utilizing concrete, rebar may be exposed for extended periods of time. The exposed rebar posses a serious risk during any fall and typical coloration of rebar posses a threat to any individual walking through the construction zone. Accordingly, regulations have been put into place to place rebar caps over the ends of the exposed rebar to provide safety in the event of fall and to provide a visual warning as to the exposed rebar.

Safety fencing may also be employed on construction sites to warn individuals of potential dangers. Traditional safety fencing is temporary fencing having a large mesh design. Like other safety devices, safety fencing is usually a high visibility orange useful for use during daylight hours.

Although barricade tape, rebar caps, and safety fencing do provide some level of safety, it is far from adequate to protect both construction workers and other individuals present on the construction site. Specifically, traditional barricade tapes, rebar caps, and safety fencing provide little warning during the night when most construction sites are left unattended. Consequently, there is a need in the construction industry for safety devices that provide warning to individuals of hazardous areas or situations both during daylight hours and in the darkness of night.

SUMMARY OF THE INVENTIVE CONCEPT

The exemplary inventive safety devices described herein can be used to provide warnings of hazardous areas or situations to individuals in daylight as well as in darkness. The inventive barricade tape includes an elongated member made from either a synthetic or organic material. The synthetic materials may include thermoplastics, thermosets, resins and polymers. In an effort to remain conscious of the environment the organic material may be biodegradable. In order to provide visibility in dark environments the inventive warning tape includes luminescent features. The luminescence of the invention may be achieved by mixing a luminescent material in the material used to make the tape. In other embodiments, a luminescent coating may be applied to the tape to achieve the desired luminescence.

The inventive warning tape can be segmented into patterns to provide warning to individuals encountering the tape. The inventive tape may also include color coatings and highly reflective elements in order to allow the tape to be visible in a variety of lighting environments.
