www.mercanta.com mechanical stress, or where little chemical resistance is required. For medium duty applications including chemical splash take polyurethane-coated polyamide fabric. All styles are available - jackets and trousers as well as coveralls. 5.0 High Visibility Safety Clothing This type of safety clothing is designed to provide high visibility under all day, night and weather conditions. The material may be 100 % proofed polyester with a quilted lining, or polyurethane coated polyester. Both materials fulfil all requirements for effective sealing against weather influences. Safety clothing should be worn by traffic workers all day and night and for all applications that require high visibility. Safety clothing features fluorescent strips that are manufactured of highly retro-reflective material for positive visibility. The material is guaranteed not to fade or lose its reflective or luminous qualities for the life span of the garment. In 2013 the EN 471 was modified and became EN 20471 which differentiates high visibility clothing into 3 classes based on the conspicuity provided, with the classes dictating the minimum quantities of background and retro-reflective materials to be used. CLASS 3: Highest Protection Level: Bands of retro-reflective material shall not be less than 50 mm wide. Minimum fluorescent material 0,80 m2. Minimum retro-reflective material 0,20 m2. The horizontal reflective bands may have an inline of +/- 20°. CLASS 2: Intermediate Protection Level: Bands of retro-reflective material shall not be less than 50 mm wide. Minimum fluorescent material 0,50 m2. Minimum retro-reflective material 0,13 m2. CLASS 1: Lowest Protection Level: Where enhanced visibility is an advantage, but for minimal risk / off road purposes only. Bands of retro-reflective material shall not be less than 50 mm wide. Minimum fluorescent material 0,14 m2. Minimum retro-reflective material 0,10 m2. The standard GO/RT 3279 defines the minimum requirements for high-visibility clothing used in the railway industry. 6.0 Disposable Garments Tyvek is spun bonded polyolefin, a low-cost, limited use material for applications in all kinds of industry. The main applications are in the fields of dust and particle holdout where the Tyvek fabric is clearly superior to both woven and non-woven fabrics. Therefore Tyvek-fabric suits fulfil the hygienic requirements of hospitals, laboratories, etc. better than normal work suits. These suits are also available with a polyethylene film coating to provide an effective acid-resistant barrier. Coated Tyvek suits are mainly used in spray painting and light chemical applications. In addition to the suits, hoods, spats and aprons (especially for poultry farm and meat-processing industry), also hats made of Tyvek fabric can be offered upon request. A similar material that offers a slightly higher protection is a polypropylene microfiber which is widely known under branded names like Microgard or Kleenguard. In food industry different requirements apply for the choice of appropriate workwear and these mainly deal with potential hygiene risks. HACCP as per EU directive no. 852/2004 for the food processing industry: The Hazard Analysis and Critical Control Point (HACCP) system is internationally accepted as the system of choice for food safety management. It provides a systematic way of identifying safety hazards and making sure that they are being controlled day-in, day-out. This includes appropriate measures to minimise the likelihood of food poisoning bacteria contaminating meat and associated products, avoid physical and chemical contaminations of meat, reduce the potential for growth of food poisoning bacteria on meat and associated products, minimise the potential for cross-contamination of ready-to-eat foods by food poisoning bacteria on meat during further processing or in the kitchen. The EEC PPE directive has identified six levels of protection (Types) to facilitate the choice of chemical protective clothing. To carry the CE marking, chemical protective equipment (category III) must pass one or more of the garment “Type” tests, meet or exceed the minimum requirements for the materials’ physical and chemical properties, and be correctly identified and labelled. Chemical Protective Clothing - Category III Other types of protection * Gives no protection against radioactive radiation. ** The antistatic treatment is only effective when relative humidity is > 25 %.
