Blue flag protection in the railroad industry provides safety to workers from the inadvertent movement of equipment on which they are working. With the many tasks workers face, they need to feel secure that the risk of an accident is minimized. Blue flag indicators communicate to workers any possible dangers through visual representations.
The blue flag policy is used to mark stationary cars day and night (flag for daytime, light for darkness). In addition to our Blue Flag Signs in English, Spanish, & French, Aldon Company, Inc. offers a variety of blue lights to maximize worker safety. We have stock items as well as the ability to produce custom signage to meet your needs.
