dunlop personal protective equipment: Safety helmets are designed to protect the head from injuries caused by falling objects and other specific factors. A safety helmet consists of a shell, liner, chin strap, and accessories. Cushioning and shock absorption: There is a gap of 25~50mm between the shell and the liner, ensuring that when an object strikes the helmet, deformation of the shell does not directly impact the top of the head. Stress dispersion: The shell is oval or hemispherical with a smooth surface, causing falling objects to slide off immediately rather than remain. Furthermore, the force at the point of impact on the shell is transmitted to the surrounding areas. The force reduced by the liner's cushioning can exceed 2/8, thereby converting the point of impact into a surface area, avoiding stress concentration at a single point on the shell and reducing force per unit area. Primarily used in metallurgy, construction, forestry, electric power, mining, wellhead operations, industry, transportation, and other sectors.

dunlop personal protective equipment structure

A safety helmet consists of three main parts: the shell, the liner, and the chin strap. Shell: This is the main component of the safety helmet, typically adopting an oval or hemispherical thin-shell structure. The rigidity of the material absorbs and disperses force, while the smooth surface and curved shape help deflect impacting objects, reducing impact duration. Depending on requirements and the need to enhance shell strength, the outer shell can be manufactured in various styles, such as smooth top, ribbed top, with brim, or without brim. Liner: The liner refers to the components inside the shell that directly contact the wearer's head, including the headband, top strap, protective strap, support strap, sweatband, padding, and adjustment cords. Liner materials can include cotton webbing, synthetic fiber straps, and plastic liners. The headband is a ring-shaped strap that fits snugly around the head during wear; the forehead section is lined with sweat-absorbing material to provide moisture wicking. Chin strap: A strap fastened under the chin to secure the safety helmet, consisting of the strap itself and a locking buckle.

Regarding safety helmet colors, principles of safety psychology should be followed. Internationally, yellow with black stripes is a common warning sign, red indicates restriction or prohibition, and blue serves as an identification marker. Therefore, white, light yellow, or light green are suitable for general work roles. For mining safety helmets, bright colors should be used to prevent accidents caused by poor visibility and to facilitate detection and alertness. In addition to black, miner's helmets come in other colors and may feature reflective or luminescent materials to attract attention in low-light conditions. Some departments use different helmet colors to distinguish job roles; for example, safety managers wear white helmets with a green cross mark, while maintenance personnel wear orange-red helmets. In forestry logging sites, red or orange-red helmets are highly visible and easy to spot.

dunlop personal protective equipment usage guidelines

Observe the following principles when using safety helmets: Before wearing, inspect all helmet components for damage, ensure secure assembly, check that the liner adjustment is tight, verify that inserts are secure, and confirm that straps are fastened. If the distance between the liner and the shell is not within 25～55mm, adjust the top cord to the specified range. Only use the helmet after confirming all components are intact. Adjust the headband length to a suitable position (moderate tightness) based on the user's head size. Helmets worn by personnel working at heights must have chin straps and rear neck bands securely fastened to prevent slipping or falling off. After a significant impact, discontinue use and replace the damaged helmet, regardless of whether visible cracks or deformation are present on the shell. Do not store safety helmets in environments with acids, alkalis, high temperatures, direct sunlight, or humidity. Avoid crushing under heavy weights or puncturing by sharp objects. The shell and liner can be washed with cold or warm water; do not dry on radiators to prevent shell deformation.
