Absolutely essential at the outset of any investigation is the securing of the integrity of the crime scene. All too often, investigators arrive at the scene to find the original condition disturbed by family members or bystanders whose often zealous attempts to be helpful destroy valuable evidential items. Each emergency scene is unique, but each has one requirement in common—CONTROL. Establish and maintain tight control over emergency scene perimeters quickly and efficiently with this brilliant yellow warning tape. Simply tie one end of the tape around a fixed item, walk around the scene’s perimeter and tie it off where desired. The tape is available in six formats to accommodate virtually any situation. Eye-catching black lettering is printed on brilliant yellow polyethylene. The tape is three inches (7 1/2 cm) wide by 1,000 feet (300 m) long. The warning repeats every 31 inches.
