Technical Examples
  1. A chemically sensitive warning apparatus capable of changing colors upon contact with a chemical is disclosed. The apparatus preferably comprises an elongated tape having opposed, first and second major surfaces and warning indicia visible to an individual viewing the first surface to provide visual indication of possible danger or hazardous condition. Mounted to the tape is at least one chemical indicator that is responsive to the presence of at least one chemical by changing colors so as to provide a visual indication of the exposure of the indicator to the chemical. The tape may also include at least one color reference indicia to facilitate interpretation of the color of the chemical indicator when the chemical indicator changes color upon exposure to the chemical.
