The БЛОКЕР® Orange (article 63715) is a disposable foam earplug manufactured by ROSOMZ — the Sukhumsky Optical-Mechanical Plant — Russia's leading developer and producer of personal protective equipment, with over 85 years of manufacturing history. Made from soft expanded polyurethane foam, the plug is rolled down, inserted into the ear canal, and allowed to expand for a close acoustic seal, achieving a Single Number Rating of 35 dB.
That level of attenuation covers the demanding noise environments found in heavy industry, construction, and processing plants. ROSOMZ has spent nearly two decades driving PPE import substitution in Russia, certifying its products to domestic occupational-safety standards across all major industrial sectors.
The bright orange color of the БЛОКЕР® makes worn protection immediately visible to supervisors and safety officers on the shop floor. The foam construction operates reliably across a temperature range of –5 to +55 °C, keeping performance stable in both heated production halls and cold outdoor worksites.
Each pair is intended for single use, eliminating hygiene concerns associated with reusable hearing protection. The combination of high attenuation, comfortable self-fitting foam, and straightforward disposable use has made the БЛОКЕР® family a standard choice for workforce hearing-protection programs across Russian industry.
