HARD HATS The Occupational Safety and Health Administration (OSHA) guidelines for head protection are referenced in 29 Code of Federal Regulations (CFR) 1910.135 and 1926.100. Occupational Hard Hats 29 CFR 1910.135(a)(1) states, "Each affected employee shall wear protective helmets when working in areas where there is a potential for injury to the head from …
Class E* Hard Hats Class E* Hard hats are designed to lessen the impact force of falling items and the risk of contact with exposed high- voltage wires. They are proof- tested at 20,000 V phase-to- ground by the manufacturer. Class C* Hard Hat 03 Class C* Hard Hat Class C* Hard hats are designed to lessen the impact force of falling items.
Each hard hat class is designed specifically to provide protection from certain types of hazards. Learning about the different hard hat classes can help ensure the right hats are used in the right situations to keep everyone safe.
Instead, this class is designed just to protect from impact hazards. In most cases, a class C hard hat will have built-in vents to help keep the wearer cool, which is why they are commonly found in hot factories or construction yards.
These are commonly used at construction sites and other areas where work is done high above the ground, which increases the risk of an object being dropped and causing injury. Type II - The type II hard hats provide protection from impact from above, but also offer protection from lateral impact.
They do provide some protection against electricity, but only up to 2200 volts.
A hard hat is one of the most common types of personal safety equipment. These safety devices provide a first line of protection from hazards such as falling objects, projectiles, bumping one's head on objects, and much more. There are many types, or classes, of hard hats that a safety professional should be aware of.
There are two main types of hard hats, which are: Type I - Type I hard hats are designed specifically to provide protection from an impact from above.
Formerly categorized as "Class A," the Class G hard hat is the most commonly sold hard hat style by Cooper Safety Supply. Class C (Conductive) Hard Hats differ from their counterparts in that they are not intended to provide protection against contact with electrical conductors.
Hard hats that are considered to be “OSHA approved” meet the minimum criteria established by the American National Standards (ANSI) and the International Safety Equipment Association (ISEA), in accordance with the most current ANSI/ISEA Z89.1-2014 (R2019) standard.
ANSI divided protective helmets into different types and classes. A hard hat type indicates the designated level of impact protection, while a hard hat class indicates the degree of electrical performance.
In these types of environments, specially designed protective helmets are required in order to counteract the dangers of electrical shock hazards. Hard hats that are considered ...
Type 1 Hard Hats: have a full brim around the entire hat. Type 2 Hard Hats: have a short brim only in the front. Type 2 hard hats are the dominant style in the field today.
Hard Hat Classes. Although all safety helmets should provide equally strong protection for your noggin, not all classes of hard hats offer up the same types of shielding.

“Accessories that can be fitted into hard hats include: 1 a retaining strap worn under the chin or at the nape of the neck 2 a bracket and cable clip for the attachment of a lamp 3 an eye shield, face shield or welding shield 4 a wide brim for additional shade in hot climates 5 neck flaps for protection against weather, molten metal splash, hot substances and similar 6 a lining for cold conditions 7 ear muffs.”
There are two types of hard hats: Type 1: reduces impact from a blow to the top of the head. Type 2: protects from blows to the top of the head and the sides of the head.
The most common PPE item for head safety is the hard hat. Hard hats protect the head, which is the only part of the body that completely encloses a vital organ and bone.
It is rounded in shape to protect the crown of the head. A suspension system is used to prevent the hat from falling off and is usually in the form of a head band placed inside the hard hat. When used properly, the shell and suspension system work symbiotically to absorb the force from a strike to the head.
Class B helmets provide electrical protection from high voltage conductors (less than 20,000 volts). Class C helmets provide only impact and penetration protection and since they are usually made of aluminum, which conducts electricity, that should not be used around electrical hazards.
Hard hats must be made out of water-resistant and slow burning material. “Accessories that can be fitted into hard hats include: a retaining strap worn under the chin or at the nape of the neck. a bracket and cable clip for the attachment of a lamp. an eye shield, face shield or welding shield.
It is generally advised to replace hard hats every two years and suspension every 12 months. It is imperative to have the proper hard hat for your working environment.
