Dating hard hats

Pouring your heart into your work is fine, but using your head at work is even better. The head is the most complex system of the human body, but it is also the most fragile and most delicate. You can generally continue living if you lose a part of your body, but not if you lose your head! There are many causes of head injuries. In several work places, workers are exposed to falling objects, walk under boards or pipes hanging at the end of a rope, have to crouch down under machines, work under vehicles, etc. What are the main types of head Dating hard hats When people talk about head injuries, we immediately think of skull fractures or concussions caused by violent blows.

We would be right to do so because these are the two most serious injuries. However, there are other types of injuries that we often Dating hard hats to take into consideration: In all of these cases, you must protect your head and select the type of protection that is suitable for both the work being done and the existing risks. Protecting yourself against falling objects and other violent impacts to the head The impact of Dating hard hats object and violent blows to the head can cause contusions and lacerations to the scalp and can sometimes Dating hard hats a concussion or skull fracture. Concussions are caused by a violent and sudden displacement of the brain within the skull.

On the side of the head receiving the blow, the brain hits the side of the skull, while on the opposite side of the blow, the brain moves away from the skull. Harmful shear stresses are then developed in the brain as well as the brain stem, that is, where the brain is attached to the spinal cord. Depending Dating hard hats the intensity of the Dating hard hats, the victim can feel a simple passing discomfort dizziness, sudden blindnessa temporary injury confusion, disorientation, unconsciousness or permanent damages: In serious cases, the Dating hard hats can lapse into a coma and die.

A skull fracture is Dating hard hats dramatic in itself. The skull is made up of a group of bones able to repair themselves like all other bones. However, if bone splinters enter the skull cavity during the fracture, they can injure the brain and cause serious permanent damage. Generally Dating hard hats, the risk of disastrous consequences increases as the intensity of the impact increases and as the pressure exerted on the skull is localized over a small surface. Hard hats are the only Dating hard hats of equipment that can protect you against these risks. Hard hats are designed to reduce the intensity of impacts to the head and distribute the pressure of the blow over a larger part of the skull.

Second, hard hats come with a type of suspension system, a headband, that absorbs the blow through its elasticity and maintains a space between the head and the shell: Hard hats are not all created equal. The Canadian Standards Association CSA prepared a series of tests to classify Dating hard hats according to their level of protection. There are three levels: G - general usage E - electrical trades C - conducting headwear If you only need to protect yourself against impacts and blows, class G and C hard hats are enough. Hard hat shells are made of fiberglass, Adult camera chat line program resin, polyester, polycarbonate, textile laminates or even aluminum class C only.

They resist impacts and punctures. Class G hard hats also resist voltages of 2, volts. Class G is recommended because in almost every work place, workers encounter low-voltage electrical devices. A few helpful hints Preferably select a smooth shell because objects glance off them more easily. This is indispensable when there is a risk of side impacts. If the shell has ridges, they could act as support for the horizontal part of the impact and the hat could be knocked off. If there is a risk of side impact, select a shell offering increased lateral elastic rigidity. For heavy work, select shells having a thickness of at least 2 mm.

They are more durable. For protection against impacts from projectiles with a high penetrating power, use thermoplastic shells: Add an adjustable fastener under your chin if the hat risks falling off when you move. Never modify your hat. For instance, if there is a hard hat available on the market that comes with welding goggles, it is safer to buy this type of hat than it is to try to make one in your garage. Protecting yourself against bumps on fixed objects in the work place Sometimes certain tasks must be carried out in tight spaces where the risk of accidentally bumping fixed objects in the work place is frequent. Examples of this type of work include working under machinery, repairing a vehicle or a piece of equipment, doing maintenance work, driving a heavy vehicle or inspecting meters.

When bumping against these objects, the impact is never as violent as receiving a hammer on the head. Results generally include lesions to the scalp: Wearing a rigid plastic bump cap, aerated or not, with or without suspension, can very well do the trick. Be careful, however; these caps are not CSA approved. They do not offer much protection against impacts from flying or falling objects and even less against punctures. Physical and electrical shocks Class E hard hats are not only designed to resist impacts and penetration but also to provide some protection against electrical shocks from accidental contact with high-voltage electrical conductors.

Experimentally, these hats can resist 20, volts ground connection. The shell is often made of high-density polyethylene or polycarbonate and has no holes and no fasteners. All of the components that make up the suspension system provide electrical resistance vinyl, leather, nylon and the entire hat contains no metal parts. Class E hard hats are suitable for linemen, miners, forestry, industry and construction workers, for manufacturing plants and public services; in short, anywhere where there is a risk of exposure to active conductors or to high-voltage electrical loads. A few helpful hints Always use original parts to replace broken parts. Carefully inspect your hat before use because any cracked or punctured shell loses resistance to the passage of electrical current.

Never repaint the shell with a paint that conducts electricity. Never place a metallic logo or sticker on the hat. The electrical protection is not valid if the shell is humid or if it is soiled from oil, grease or any other conducting chemical. Winter head covering must not have any metallic accessories nor contain materials that conduct electricity. The sun It is not recommended going bare-headed in the sun for a long period of time because with the sun also comes the risk for heatstroke, heat cramps and sunstroke.

The most serious case of this type of injury is sunstroke, characterized by headaches, dizziness, fatigue, warm, dry and red skin, an elevated heaart rate and rapid breathing. Severe exposure leads to confusion and even attacks, convulsions and coma. When wearing a hard hat is not mandatory, a simple cap made of light material or a straw hat will do. If wearing a hard hat is mandatory, select a hard hat equipped with a large brim around the entire shell. You can also equip the hat with a headband and a sweatband. If electrical protection is not necessary, you can wear a Class C hat equipped with side ventilation holes.

A few helpful hints Select a hard hat that comes with a visor in the front. Attach a havelock to your cloth cap or to the back of your hat to protect your neck. Use hats with large brims to protect your neck, shoulders and face as much as possible. The best hard hats are those that passed the ageing test. They resist the impact test after hours of exposure to a watt xenon lamp. The cold A variety of hats exist to protect you from the cold, such as the tuque, the fur hat with or without ear flapsmufflers and the balaclava. If you must wear a hard hat, there are several liner models that you can add to your hat to protect yourself in winter.

Head bands fit over the hat and keep the cold and the wind from entering between the inner head band and the shell. Winter liners can be worn directly on the head under the head band. If you want, you can find liners available on the market that also protect the neck, the nape of the neck, the cheeks, part of the face, the upper shoulders or all of these at once. There are no specific rules to help you with your selection. A few helpful hints You must use a liner made of dielectric material for Class G and E hats in order to preserve their level of electrical protection. Certain liners are fire resistant. They are generally made out of Nomex or Kevlar.

In mid-season, it often becomes necessary to wear waterproof liners for protection against the rain. Adjust the headband properly before beginning to work. Other hats It's up to you to select the right hat. Properly identify the risks and purchase the hat that will protect you best. For instance, when risks of impact and bumping are minimal and risks of sparks and dust are high, you can wear a skull cap or a cloth or leather cap. We often see these caps in garages and mechanical maintenance services, on welders and during blow-torch cutting. If the only risk is one related to hair getting caught in moving parts, falling into food or flying away due to the static electricity created by rotating parts, pulleys and belts, you can wear a hairnet made of cloth rayon, nylon, cotton … or elastic, with or without mesh.

Learn to select the right hat and use it at the right time and in the right place. This way, you may avoid a regrettable head injury. You can order additional copies of this publication, indicating the departmental catalogue number LT, from:
