PPE Training Module 1: Head Protection (Hard Hats) Training on the use of hard hats in the workplace Reviewed against AS 1800:1998 Original slides from Washington State Department of Labor and Industries Head Protection (Hard Hats) The following topics will be covered: • Head Hazards • Types of Hard hats • Limitations • Use and Care Your Head The human skull does a pretty good job of protecting the brain, eyes, ears and nose, but it has its limits. The force of a golf ball hitting your head at moderate speed, or simply walking into a hard object can fracture your skull. A stronger force can cause more severe injuries. Since head injuries can be very serious, head protection is required on certain kinds of jobs. Possible Head Injuries Falling or flying objects are a common cause of head injuries. Also, falling onto or walking into hard objects can cause serious head injuries. These injuries can include scalp lacerations, neck sprains, concussions, skull fractures, brain damage or even death. How Hard Hats Protect You Hard hats protect you with the following: • A rigid shell that resists and deflects blows to the head; • A suspension system inside the hat that acts as a shock absorber; • A shield for your scalp, face, neck, and shoulders against overhead splashes, spills, and drips of hot or caustic liquids; • Some hats serve as an insulator against electrical shocks. Where Are Hard Hats Required? • Any worksite where you are potentially exposed to flying or falling objects; • Around or under scaffolds or other overhead structures; • Any demolition work with overhead hazards; • Any other locations required by company policy. When are Hard Hats Required? • Risk of be hit by flying or falling objects; • While working as a flagger; • Work near live electrical conductors that could contact your head. Where We Require Hard Hats List your specific locations, jobs or tasks where hard hats are required at the worksite. Using A Hard Hat Adjust the suspension inside your hard hat so that the hat sits comfortably, but securely on your head. Care Of Hard Hats Clean your hard hat as needed to remove oil, grease, chemicals, and sweat that can collect in and around your hat. You can clean your hat with mild soap and hot water for 5-10 minutes. Rinse with clear water, wipe, and let air dry. Because prolonged exposure to sunlight and heat can damage your hat, store it in a clean, dry, and cool location out of direct sunlight. Hard Hat Replacement Inspect headwear before each use for any visible signs of dents, cracks, gouges, penetration, chalking, loss of gloss or any other signs of damage that might reduce the degree of safety originally provided. Replace hat when hairline cracks start to appear. Replace hat that has been struck by a forceful object, even if no damage is obvious. Hard Hat Replacement (continued) Safety helmets have a "use by date" or a "working life”. Each helmet, when manufactured, has a year and month of manufacture stamped onto the inside of the shell near the peak for easy reading. The arrow in the stamp points to the month and the year overlays the arrow. For example below, the arrow points to 9 and the number is 04 means that the helmet was manufactured in September 2004. Hard Hat Replacement (continued) If the helmet has been used regularly it should be replaced after 3 years from the date of issue. The date of issue should be marked on an additional sticker on the inside of the helmet at the back of the shell. The date of issue is not necessarily the same as the date of manufacture The harness/headband has a life of 2 years and should be replaced at an earlier date. Hard Hat Suspension what’s under the shell Inspect suspension before every use. Look for cracked, torn or frayed straps. Replace suspension when damage or defects are detected. Suspensions will deteriorate over time from exposure to sunlight and chemicals, perspiration and hair oils. The normal service life of the suspension is about one year of regular use. The suspension may last longer with intermittent use. Hard Hat Suspension (continued) Don’t mix different manufacturer suspension types and hard hats. Replacement suspension harnesses must be from the same manufacturer and for the same model of hard hat. Don’t wear a hard hat backwards unless you rotate the suspension. Use Of Hard Hats Don’t use paint, solvents, gasoline, chemicals, or harsh cleaning materials on the shell. Before any application of adhesive tape, advice should be sought to ensure that the tape adhesive will not degrade the shell material. Generally, self-adhesive pads or stickers have been found not to affect the shell material adversely. Use Of Hard Hats (continued) Don’t transport headwear in rear windows of vehicles since sunlight and extreme heat will weaken it. Don’t put anything in the space between the suspension and the shell. Types Of Hard Hats Type 1—Industrial This type of helmet was formerly known as the industrial safety helmet. It is suitable for work in the construction industry, factories and quarrying. Type 2—High temperature workplaces This type of helmet as well as meeting the requirements of Type 1 helmets, is intended to withstand exposure to high temperatures such as may be encountered in steelworks. It has a shell of a heat resistant material, and may have ear and neck protectors intended to have a low flammability. Types Of Hard Hats (continued) Type 3—Bushfire fighting As the name implies, this helmet is intended to be worn by people involved in bushfire fighting. It meets the requirements of the basic, Type 1, helmet as well as requirements for retro reflective marking and flammability. NOTE: Different optional or additional design and performance requirements are specified in AS/NZS 1801. They may be specifically requested by a user, e.g. a Type 1 helmet intended to be worn by people engaged in underground mining may have retro reflective marking and use specific accessories. Type of accessories A wide range of accessories can be fitted to helmets to make them more suitable for variable working conditions. Examples are as follows: (a) A retaining strap worn either under the chin or at the nape of the neck. The strap is usually of elasticized tape attached by plastic fittings to the helmet shell. (b) A bracket and cable clip for the attachment of a lamp*. (c) An eye-shield, face-shield or welding shield. (d) A wide brim for additional shade in hot climates. (continued) (e) Neck flaps* for protection against the sun and adverse weather conditions, or for protection against molten metal splash, hot substances and similar hazards. (f) A liner for cold conditions. (g) Earmuffs. (h) A sweatband for dusty conditions. Prospective purchasers of helmets fitted with such accessories should ensure that helmets fitted with such accessories still comply with AS/NZS 1801. Stories On How Hard Hats Saved Lives One of the most basic adages of construction safety is that hard hats save lives - but they only work when they're worn. This means 100% of the time everywhere - no excuses. This adage was recently proven out by an incident on a painting project in Buffalo, New York. A worker was suiting up to begin blasting in preparation for repainting on a nearby bridge. He was not exposed to traffic and was not under an overhead hazard. Nonetheless, he was wearing his hard hat as required by the specs, and as directed by accepted safety practice and by good common sense. Stories On How Hard Hats Saved Lives (continued) Adherence to this simple rule probably saved the worker's life. Suddenly, without warning, a steel hatch blew off the top of the pressure blasting equipment which was several feet away from the worker. The 100 lb steel hatch flew several feet through the air and struck the worker squarely on the top of the head. The force of the blow knocked him to the ground, and as might be expected, he was dazed by the impact. He was transported to a nearby hospital as a precaution, but he was found to have no significant injuries, and was released without even being kept overnight. He is expected to be back on the job before the end of the week. Stories On How Hard Hats Saved Lives (continued) The lesson learned is very simple - HARD HATS SAVE LIVES! In this case, eyewitnesses emphatically report that the hard hat saved this worker from very serious and probably fatal injuries. The scars on the hard hat bear them out. However, hard hats can do their job only if they are worn all the time. Even in locations where the risk of head injuries is not apparent, unexpected incidents such as this equipment failure can occur with no warning. A hard hat laying on the front seat of a vehicle, or sitting on the ground, or even held in your hand, cannot provide any protection. Hard hats are a basic tool for the construction trade, and they must be worn all the time - everywhere everyone! Your life depends on it!
