Block off areas with caution tape to prevent people from entering. Crime scene tape and other types of safety tape are a clear and obvious way to let people know there's been an incident or that they need to find a different route to their destination. Use safety vests and other traffic safety products to help maintain security around an area and keep traffic moving smoothly.
Yellow tape with the word "CAUTION" displayed in black along the length of it is the easiest way to let people know they need to be careful around a certain area. With black and yellow stripes, hazard tape also provides a simple way to indicate that an area is off-limits. Keep these tapes at the office in case of emergency and use it to block off unsafe indoor corridors or unsafe outdoor roads.
Some safety tape is made with an adhesive backing for easy setup. Other safety tape is non-adhesive to help maintain flexibility if tape needs to be moved around.
