Unlike head and foot injuries for example, respiratory injuries are not readily apparent in the workplace. In some cases it may not be until after workers retire that symptoms and diagnosis happens. It is therefore very important that all staff who are, or may be, at risk have access to Dust Masks that meets the appropriate European standard. Five common workplace respiratory hazards where Dust Masks can be used: Dusts - produced when solid materials are broken down into finer particles, the longer the dust remains in the air the easier it is to inhale. In general the smaller the dust particle the greater the hazard it presents; Mists - tiny liquid droplets formed by atomisation and condensation processes such as spraying. Mists are often combinations of several hazardous ingredi ents; Metal Fumes - occur when metals are vapourised under high heat. The vapour is cooled quickly and condenses into very fine particles that float in the air. Many processes form fume such as smelting, pouring metals and many welding applications; Gases - airborne at room temperature. Able to diffuse or spread freely, can travel very far very quickly; Dust Masks are NOT suitable and a respirator mask with filter cartridges should be used Vapours - gaseous state of substances that are liquids or solids at room temperature. Formed when substances evaporate in the way water vapour evaporates from water: Dust Masks are NOT suitable and a respirator mask with filter cartridges should be used To help you meet the Health and Safety Executives demands and to protect you, our dust mask range consists of a wide choice of products from fold flat disposable dust masks to full face safety masks.
