Why Use a Hard Hat
A hard hat protects you from head injuries. It is made to either redirect a blow or dissipate its energy to ensure head protection. Various sectors, like construction, utilities, manufacturing, and others have distinct rules and advised guidelines on hard hat safety, type and classes.
Categories of Hard Hats and Their Classification
The type of a hard hat depicts the impact protection it offers, while the class denotes the degree of electrical protection.
Hard hat impact protection is divided into two categories: Type I and Type II.
1. Type I Hard Hat:
Type I Hard Hats are intended to reduce the force of impact resulting from a blow only to the top of the head. This form of impact, for example, may result from a hammer or nail gun falling from above.
2. Type II Hard Hat:
Type II Hard Hats are intended to reduce the force of lateral impact resulting from a blow that may be received off-center, from the side or to the top of the head. This form of impact, for example, may result from contact with the sharp corner of a side beam.
There are three classes of hard hats for different types of electrical protection. These also include full-brim, cap-style hats and hard hat accessories.
- Class G Hard Hats: General protective helmets provide impact protection but have low voltage protection. They are used for general purposes where no heavy machinery is present.
- Class E Hard Hats: These safety helmets protect against dropping objects, blows and voltages of up to 20,000 volts. They must undergo dielectric testing and are often used in construction sites.
- Class C Hard Hats: These hard hats do not offer electrical protection but only impact protection. They are used where no electrical exposure is present.
Other models are full-brim hard hats that protect against sun/rain. You can affix attachments like face shields, lamps and earmuffs for added protection.
Hard Hat Regulations and Standards
OSHA has general standards for the best hard hat protection in various categories of businesses, such as construction and manufacturing. Everyone must wear these hats in construction areas with falling objects and near exposed electrical conductors.
In addition to regulatory compliance, most of the safety guidelines that refer to the use of hard hats include issues to do with storage and replacement of hats as recommended by the manufacturers. For instance, hard hats should be changed after 2 years or after any impact has occurred.
Best Hard Hats for Construction
When choosing the best construction hard hat, a few key considerations must be taken care of.
1. Class/Type:
Consider the type of hat you’ll need for the project. Any electrical work is classified as Class E. At the same time, the general sites are classified as Class G. Cap or full-brim designs can also be incorporated to suit the working conditions.
2. Comfort:
Spring mechanisms, shock absorbers, cushions, alloys and opening and closing vents are some additional features you can opt for. Some also offer the possibility of controlling the temperature in a warm or cool climate but can drive up the cost. Consider which features you will need.
3. Accessories:
Some accessories that you can affix to the hat include face shields, lamps and earmuffs. Be sure to plan a prototype before purchasing in bulk, if needed.
4. Brand Reputation:
Consider purchasing hats from brands prioritizing safety standards for better quality. These standards come in two certifications, namely ANSI and CSA. So, look for any quality mark that the hat may come with.
5. Fit:
Remember to buy the correct size. Choose hats that fit easily over the chin and snugly to the user’s head while performing the twist test.
You can increase the helmet's visibility by using high-index colors such as yellow, orange or lime.
Knowing the right hard hat and its proper use can improve head safety manifold. Consider your requirements for the type, classification, certifications, stowage and replacement intervals of hard hats while purchasing them. Proper usage must also be determined to meet set requirements and avoid head injuries at the workplace. Look for safety by choosing and using the best hard hat for a certain job and conditions.
