Safety Helmets

Safety Helmets: Overview

Safety helmets are intended to protect people against hazards such as impact, penetration, electrical shock, and dropped objects in the workplace. The safety helmet is usually manufactured using materials such as high-density plastics, thermoplastic resin, and composite materials which have the capability of absorbing impact energy. The construction sector, manufacturing firms, oil and gas sectors, utility firms, mining firms, and warehouse management firms all need to wear safety helmets as part of their safety gear. Manufacturers and suppliers produce numerous kinds of safety helmets that are meant for different hazardous environments, hence making the safety helmet one of the most important safety equipment for industrialists.

How It Works

Safety helmets protect the individual wearing the helmet without mechanical functioning but through the design of the helmet shell along with the internal suspension system. The outer shell of the helmet absorbs the impact energy and spreads it out over a wider area rather than concentrating it in one particular spot. The inner part of the helmet consists of straps, cradles or foam padding making a space between the outer shell and the head of the wearer; hence creating more chances of absorbing the energy.

The functioning of the helmet totally depends on the material of the shell, the design of the suspension and manufacturing process. There are a variety of materials used to manufacture the shell of the helmet, and some of the common ones include HDPE which is cheap and offers high impact protection. There are more expensive materials that provide additional strength. The manufacturing process determines the performance of the helmet.

Varieties Available

There are different styles of safety helmets, which can be used for different hazards and different industries and workplaces:

• Type I Helmets: These helmets are designed to protect the user from impact to the top of the head. They are often used in general construction and industrial applications.
• Type II Helmets: The design of this helmet allows the wearer to be protected from both top and side impacts and can be used when working in confined areas where lateral impact is a hazard.
• Class E (Electrical) Helmets: Insulation helmets for high voltage electrical work for use near live electrical parts.
• Class G (General) Helmets: Standard impact and low voltage electrical helmets for industrial use.
• Vented Helmets: Helmets with holes for increased ventilation and used in hot environments and physical activity outside.
• Full Brim Helmets; helmets with an extra wide brim that provide more sun, rain, and debris protection than traditional hard hats.

How to Use

• Proper suspension setting in relation to proper head size is essential in ensuring that you get the perfect fit.
• Put the helmet correctly on your head with the brim straight, at ground level.
• Make sure that you fasten the strap under your chin during activities at heights, when operating any moving machine, and during windy situations.
• Do not adjust the gap between the shell and suspension, especially by adding more padding.
• Firmly secure all your protective devices via the mount holes in the shell.
• Make sure that you inspect the shell and suspension condition prior to the shift every time.
• Change your helmet every time it is hit, regardless of the impact.
  

Industry-Specific Requirements

At times, the choice of helmet may depend upon the types of hazards in the region. Therefore, it is important to choose a helmet based on the job site.

• Construction Industry Requires Either Type I or Type II helmet with a high degree of impact resistance and compatibility with attachments such as face shield for grinding and cutting jobs.
• Electrical and Utilities Industry Requires A helmet that should have an insulation rating of Class E and should have nonconductive accessories, as it needs to be used when working around exposed live electrical conductors.
• Oil, Gas, and Petrochemical Industries Require shell material that should be heat and chemical resistant as there is a risk of coming into contact with solvents.
• Mining Industry Requires A helmet where headlamp attachment is possible and it should have a high lateral impact resistance properties.
• Warehousing and Logistics Industry Requires Lightweight vented Type I helmets or bump caps.
