Head protection, such as hard hats and bump caps, is a critical component of personal protective equipment (PPE) in environments with risks of falling or flying objects and impacts. Employees should wear hard hats or bump caps to protect against head and neck injuries.
Hard Hats & Bump Caps: Essential Personal Protective Equipment
Explore the essentials of industrial head protection, such as bump caps and hard hats. Learn about the types, standards, and care tips to ensure safety.
OSHA (Occupational Safety and Health Administration) standards require the use of industrial head protection in workplaces where head and neck injuries are possible. To ensure effective impact reduction, all industrial headgear must comply with the latest ANSI Z89.1 requirements for industrial head protection.
Types of Head Protection
Hard Hats & Bump Caps
Hard hats are used to reduce the force of impact from dangerous materials while on the job. You can find hard hats in full-brim, short-brim, and standard styles.
Bump caps protect the head from minor bumps, lacerations, and other light injuries. Use them in areas where ANSI-compliant head protection is not required. Bump caps do not protect against falling objects. Some are available with inserts and LED lights on the brim of the cap.
ANSI Type Impact and Protection:
In the latest revision of the standard 289.1-2003, ANSI specifies requirements for two Types and three Classes of head protection. The Type categories define the area of impact and penetration protection.
Type I caps and hard hats provide protection from objects falling overhead, directly onto the top of the helmet. They do not protect from objects that may strike from the side, front, or rear. These are the familiar hard hats of conventional design and constitute the majority of industrial safety helmets. Type I helmets feature impact and penetration resistance, and dielectric performance.
Type II caps and hard hats provide the same degree of protection to the top of the head as Type I. In addition, Type II helmets have an extra layer of shock-absorbing material, which provides a degree of protection against blows to the side, front, and rear of the head. These caps and hats may be useful for workers who are not always working in an upright position.
Classes of Head Protection:
Classes define levels of protection from electrical hazards.
Class C caps and hard hats are conductive and don’t offer electrical protection. They are used where there is no possibility of exposure to electric shock or burn.
Class E caps and hard hats are used for electrical applications and protect against contact with high-voltage conductors. They have the highest rating and are tested at 20,000 volts AC for three minutes. Class E, formerly designated Class B, also meets Class G and Class C regulations.
Class G caps and hard hats are used for general applications and protect against limited electrical shock and burns. They are tested at 2,000 volts AC for one minute. Class G, formerly designated Class A, meets Class C regulations.
*Note: The voltages listed above are not intended to be an indication of the voltage at which headgear protects the wearer. It indicates only the level at which they are tested.
Hard Hat Accessories Tip
Manufacturers design some models of bump caps and hard hats that can support accessories, such as face shields and hearing protectors. Ensure that these additions do not adversely affect the product's original degree of head protection, particularly the use of accessories with metal parts, which may affect the voltage protection capabilities of Class G and Class E head protectors.
The Use, Care, and Replacement of Bump Caps & Hard Hats
Replace bump caps and hard hats periodically to ensure they continue providing protection. Proper use and care ensure a longer lifespan. Some suppliers recommend replacing suspensions every 12 months and the complete unit every five years.
Important precautions when caring for safety caps and hats:
• Increase your feed.
• Avoid the use of adhesives, paints, or cleaning solvents. These may attack and damage the shell, reducing its level of protection. Clean the shell with mild detergent and warm water.
• Avoid exposure to extreme heat or cold and excessive sunlight, such as in the rear window of a car.
• Visually inspect the bump cap or hard hat daily for signs of wear, dents, cracks, or other damage.
• Replace the shell when signs of damage or wear occur or if it has been subjected to impact.
• Replace suspensions and brow pads when damage or excessive wear is detected.
