Safety helmets are classified into two types
- Full-brimmed type helmet
- Brimless with peak
Classification of Hard Hats
The hard hats are classified into mainly four classes
- Class A
- Class B
- Class C
- Class D
Class A- Limited Voltage Resistance for General Services
- Class A safety helmets are High Voltage resistance and had limited resistance for general services.
- This kind of hard hat provides impact and penetration resistance with voltage protection. It provides voltage protection of up to 2200 volts.
- Class A helmet shells are water-resistant and slow-burning.
- Class A safety helmets should have water absorption of the shell after 24 hours of immersion test should not be more than 5%.
- Class A safety helmets should be tested up to 2.2 kV for a time period of 3 minutes with leakage currents. It should not exist at 9 mA.
Class B-High Voltage Resistance
- Class B safety helmets provide the highest level of protection against various electrical hazards and shocks and burn protection.
- Class B safety helmets should be water-resistant and slow-burning.
- Class B safety helmets also provide good protection from impact and penetration hazards by falling objects.
Class C- No Voltage Protection
- Class C safety helmets are also known as metallic helmets or bump caps.
- It is designed in such a way that it will use in areas with low head clearance.
- Classic C helmets are not designed to protect against falling objects or electrical hazards.
- Class C safety helmets are generally recommended for Areas where protection is needed from head bumps.
Class D-Protection for Fire Fighting
- Class D safety helmet is fire resistant and non-conductor of electricity.
- Class D safety helmets are specially designed for firefighting.

What Are Hard Hats Made Of?
Hard hats are helmets designed for work environments such as manufacturing, industrial and construction sites to protect the head from injury. The outside shells are usually made from high-density polyethylene (HDPE) or a polycarbonate resin as they are strong, easy to mold, lightweight, and do not conduct electricity.
What Is a Bump Cap Used For?
Bump caps protect against small impacts that a worker may incur when bumping into or knocking against a stationary object, while hard hats offer additional protection against falling or moving objects.
What Are Hard Hats Used For?
Purpose. Hard hats are required when working in areas where there is a potential for injury to the head from falling objects. In addition, hard hats designed to reduce electrical shock are required when working near exposed electrical conductors that may contact the head.
What Is a Type 1 Hard Hat?
Hard hat impact protection is divided into two categories: Type I and Type II. 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.
Colored Hard Hats Meaning
White – for managers, foremen, engineers or supervisors. Green – for safety inspectors, new or probationary workers. Yellow – for general labourers or earth-moving operators. Brown – for those involved in high-heat applications such as welders. Blue – for carpenters, electricians and other technical operators.
Construction Helmet Meaning
A hard hat is a type of helmet predominantly used in workplace environments such as industrial or construction sites to protect the head from injury due to falling objects, impact with other objects, debris, rain, and electric shock.
Classification of Hard Hats
The three classes are based on the level of protection they provide from electrical hazards. Class G (General) hard hats are rated for 2,200 volts. Class E (Electrical) hard hats are rated for 20,000 volts. Class C (Conductive) hard hats do not offer electrical protection.
Why Are Hard Hats Important?
Hard hats are required when working in areas where there is a potential for injury to the head from falling objects. In addition, hard hats designed to reduce electrical shock are required when working near exposed electrical conductors that may contact the head.
What Class of Hard Hat Is Used for Minor Bumps?
Your hard hats must meet with one of the three classes: CLASS G: These are general hard hats rated for 2,200 volts. CLASS E: These are electrical hard hats rated for 20,000 volts. CLASS C: These are conductive hard hats, and they do not offer electrical protection at all.
What Are Class C Hard Hats Used For?
A class C helmet is acceptable on construction projects for protection against impact and penetration of falling and flying objects but not for electrical hazards.
How Long Are Hard Hats Good For?
The most common service life guideline states that hard hat shells need to be replaced after no more than two years of regular use or five years from the date of manufacture—whichever comes first. The life for suspensions is shorter, with replacement needed after no more than twelve months.
When a Hard Hat Sustains an Impact It Should?
Always replace the hard hat if shell damage is visible or when the hard hat sustains an impact, even if the damage is not noticeable. Never drill holes, paint, or apply labels to protective headgear. This may damage the shell and reduce the level of protection.
Are Hard Hats Recyclable?
The answer to that would be yes! As most hard hats are made of #2 plastic (high density polyethylene or HDPE – a type of plastic), that means you can easily recycle hard hats.
When Were Hard Hats Invented?
The ‘Hard Boiled® Hat’, patented in 1919, was so called because of the steam used in the manufacturing process,” said Bullard. “The original ‘Hard Boiled® hat’ was manufactured out of steamed canvas, glue, a leather brim, and black paint.
