Protection of the head is a necessary preventive protection for every worker not only in the construction industry but also in industry and other working environments. The highest degree of protection of the head and its surface from injuries can be ensured by protective helmets. In our offer you can choose from many types of work helmets according to EN 397. We supply spare parts such as chin straps, protective shields, shield holders, ear muffs, sweat straps, inner liner helmets, etc. We also offer safety caps with plastic inner reinforcement certified according to EN 812.
In order to adequately protect the hearing against the negative effects of noise on humans, ear plugs or ear muffs are intended. Their use is required where technical measures fail to reduce noise to an acceptable level. If the noise level is higher than 85 dB, it is essential to use hearing protectors, as irreversible hearing damage can occur with these values and 8 hour exposure. When selecting hearing protectors, a variety of products are available that have different properties, which requires them to choose those that are most suitable for protection at a particular workplace.
Protective helmets are often worn several hours a day. From this reason we recommend paying attention not only to meeting all safety criteria, but also focusing on the weight of the helmet, the ventilation capability and the quality of the inner ear pads to ensure maximum comfort for the wearer.
Lifetime of safety helmets – helmet is not forever!
The life of the helmets is limited, as their material degrades with increasing time. A reduction in mechanical properties occurs even if the helmet is not used and is only stored. Other factors that affect the life of the helmet include cold, heat, chemicals, UV radiation, or even misuse. The more the helmet is exposed to these effects, the earlier it should be replaced.
The current version of EN 397 requires that the data on aging and lifespan be included in the helmet instructions. In general, however, thermoplastic helmets (PE and ABS) should not be used for more than 4 years, and helmets from duroplasts should not be used for more than 8 to 10 years, of course depending on the conditions and frequencies of use, exposure to chemicals, climatic conditions, etc.
The higher the attenuation, the better?
The right is a reasonable damping. It is mistaken to assume that the higher the attenuation, the better the hearing protector. The hearing loss attenuation value must be chosen so that the noise level in the ear is between 70 and 75 dB. In case of insufficient attenuation, there is a risk of hearing damage in connection with noise. Excessive attenuation may prevent communication and audible alertness. At the same time, the user may feel isolated from the environment. As a result, hearing protectors may not be worn throughout exposure and hearing protection can be significantly reduced.
Employer's responsibilities are to monitor the noise level and ensure a healthy working environment for its employees. The employer is required to take measures to protect employees from the risks associated with noise due to its consequences for the health and safety of employees, in particular hearing damage. Haberkorn offers a wide range of suitable hearing protectors.
