In this article, you will get to know the different types of hard hat color codes used and the meaning of the hard hat color code.
Why Are Hard Hats Important?
Hard hats are important to protect workers from potential hazards. Hard helmets are required by law in many industries, and the colors of hard hats can aid workers in maintaining awareness of their surroundings. Workers must be familiar with the meaning of each color code because there are different color codes for different types of hazards. Many workplace accidents occur on construction sites, affecting both male and female workers, and we can mitigate the severity of the hazards by wearing safety helmets or hard hats. As a result, it’s also important to know the helmet colors.
Purpose of Hard Hat Color Code
The purpose of the safety hard hat color codes is to guide workers in identifying potential hazards. In several industries, hard helmets are mandated by law, and the colors of hard hats can aid workers in maintaining awareness of their surroundings. There are different color codes for various kinds of hazards, so it’s important to know what each color implies.
Various colors typically have different meanings on different work sites, so it’s important to ask your supervisor or safety coordinator what the colors indicate on your particular jobsite.

Classification of Hard Hat
There are primarily four classes of hard hats.
- Class A
- Class B
- Class C
- Class D
Class A: General Services with Limited Voltage Resistance
- Class A safety helmets are resistant to high voltage and have limited resistance for general services.
- This type of hard hat provides impact and penetration resistance as well as voltage protection. It protects against voltages of up to 2200 volts.
- Class A helmet shells are water-resistant and slow-burning.
- Class A safety helmets should not have more than 5% of the shell’s water absorption after a 24-hour immersion test.
- Class A safety helmets should be tested with leakage currents up to 2.2 kV for 3 minutes. It shouldn’t exist at 9 mA.
Class B: High Voltage Resistance
- Class B safety helmets provide the highest level of protection against electrical hazards, shocks, and burns.
- Class B safety helmets should be both slow-burning and water-resistant.
- Class B safety helmets also provide protection against impact and penetration hazards from falling objects.
Class C: No Voltage Protection
- Class C safety helmets are also called metallic helmets or bump caps.
- It is designed for use in areas with low head clearance.
- Classic C helmets are not intended to provide protection from electrical hazards or falling objects.
- Class C safety helmets are typically recommended for areas where head bump protection is required.
Class D: Protection for Fire Fighting
- A Class D safety helmet is fire-resistant and electrically nonconductive.
- Class D safety helmets are designed specifically for firefighting.
- Water absorption in class D safety helmets should not exceed 5%.
Different Hard Hat Color Codes and Their Meanings
Depending on the type of work being performed at the given location, there are predefined standard hard hat color codes that must be followed.
