Safe-t engineers supplies ear plugs that filtrate noise, but not effective sound of process indicators, emergency instruction, etc., thus attending the user`s communication needs. Ear plugs contain three concentric tapered flanges to reflect sound waves. Being designed from soft, flexible and rugged synthetic rubbers, the surface happens to be smooth for comfort and all day use. The bright colour of the ear plugs from safe-t engineers ensures high visibility and simplifies safety checks. The salient features of the ear plugs include: non-toxic, non-allergent, reusable up to 6 months, and easy to fit and maintain. These ear plugs are ideal moderate noise environment and competent for many industries, traffic sound pollution, factories, where noise level is high. These ear plugs from safe-t engineers are mainly used in wood processing, construction, and metal industry or positioned near engines and turbine machinery noise, warning alarms and others.
