Safety Tags are an inexpensive fast solution for temporary marking and identification of hazards. Attach and hang tags as close as possible to hazard situations where the tag can be readily seen. Plastic Tags are weather-resistant and chemical-resistant for use in dirty and greasy environments. Tags are flexible and easy to write on. Tags are printed on both sides and measure 6 x 3-1/2 in. with a 3/8 in. hole reinforced by a metal grommet. Tag text: Danger Do Not Operate Back B.
