Hard Hats, Helmets and Safety in Construction According to Wikipedia – A hard hat is a type of helmet predominantly used in workplace environments such as industrial or construction sites to protect the head from injury due to falling objects, impact with other objects, debris, rain, and electric shock. Suspension bands inside the helmet spread the helmet’s weight and the force of any impact over the top of the head. A suspension also provides space of approximately 30 mm (1.2 inches) between the helmet’s shell and the wearer’s head, so that if an object strikes the shell, the impact is less likely to be transmitted directly to the skull. Some helmet shells have a mid-line reinforcement ridge to improve impact resistance. The rock-climbing helmet fulfills a very similar role in a different context and has a very similar design. During the past few decades various materials were used in the manufacturing of hard hats. During the 1930’s steel was replaced by Alluminium. Fibreglass came into use in the 1940’s. Thermoplastics took over in the 1950s until in the 1960’s when the first polycarbonate hard hat was introduced. Today, most hard hats are made from high-density polyethylene (HDPE) or advanced engineering resins, such as Ultem. In 1997 ANSI allowed the development of a ventilated hard hat to keep wearers cooler. Accessories such as face shields, sun visors, earmuffs, and perspiration-absorbing lining cloths could also be used; today, attachments include radios, walkie-talkies, pagers, and cameras. There are many factors to consider such as Strength, Weight, Comfortability etc. FEM offers the following advice: Head protection is required on almost all construction sites. It is important for construction work to be organised to minimise all risks to workers, however, it is likely that hazards will still remain, and everyone will be required to wear safety helmets at all times while on site. FRP safety helmet OEM printing personalized construction engineering Employees should be provided with a safety helmet or hard hat for use at work; bump caps only protect from non-moving hazards and are not adequate protection for construction workers. Acceptable head protection should: · Be in good condition. Do not wear damaged PPE. If it’s damaged, it must be thrown away and replaced by the employer. · Be a good fit for each individual and be worn properly. · Not prevent someone from wearing hearing protection when required. · Only be purchased from a reputable supplier.
