- Hardhat_mounted_mirror abstract "A hardhat mirror is a safety device attached to a hardhat that provides an increased field-of-view.Hardhat mirrors are typically very small due to the close visual proximity and are made of ABS plastic with a reflective surface of either glass or acrylic. Some headgear-mounted mirrors are held permanently in place with adhesives although ones designed specifically for industrial applications are mechanically attached and are therefore removable and have a higher degree of adjustability. They also have hinged joints for adjustability and to be able to be completely moved out of the way of peripheral view when desired. The reflective surfaces are typically between one to just over two square inches of surface area.They are used in dangerous workplace environments by pedestrian workers or by operators of small equipment like jackhammers and concrete saws, who are susceptible to being hit or struck from behind. This type of fatality, on average, is about 40 per year in the US over the last 10 years. They are usually an optional device and not a required piece of personal protective device, although they have been recommended by the National Institute for Occupational Safety and Health (NIOSH) and the state of Washington. Hardhat mirrors are used as an alternative to additional employees known as “spotters” acting as an observer during especially dangerous activities.Washington State’s Department of Labor and Industries studied hardhat mounted mirrors’ effectiveness as a run-over and back-over safety device. The study, done in 2000, is titled “Optical Properties of Plane and Convex Mirrors: Can Mirrors Be Used to Enhance Construction Flaggers’ Safety?” The conclusion states: “Given that image perception is a problem with small-radius-of-curvature convex mirrors and that it is difficult for a flagger to view the flagpole mirror and keep an eye on traffic in front of them, helmet mirrors have been found to be the best option for flaggers.”".
