Ear Plugs

Conical Shape Disposable Metal Detectable Foam Earplug Features: EP-33F metal-detectable foam earplugs are designed to protect the ears from loud noises while also being detectable by metal detectors. This is particularly useful in industrial settings, such as the food processing industry, where foreign objects must be avoided at all costs. The earplugs are made of safe and non-toxic PU foam, which means they won't cause any irritation or allergies when they come into contact with the skin. They are also moderate in size, making them suitable for most people's ear canals, and come in a range of packaging options to meet individual needs. The metal detection capabilities of these earplugs are invaluable in ensuring safety in the workplace. If the earplugs are dropped down the production line and a metal object is detected, a loud beeping sound will alert the wearer to the potential danger in the area. Not only do these earplugs offer metal detection, but they also provide a high level of noise reduction, with a Noise Reduction Rating (NRR) of up to 32 decibels. This makes them ideal for workers who are regularly exposed to loud noises, as they can help prevent hearing damage and other related issues.
