    Taking care of your work clothing

    Taking care of your work clothing is important. Without taking the correct care for your garments, you run the risk of impacting the effectiveness of the product. This can lead to the garment not giving you the protection it advertises. All protective work clothing has different

    ISO 20471 High visibility clothing care

    The purpose of high vis clothing is to give the wearer improved visual acuity whilst onsite or working in low light or hazardous areas. If high vis clothing isn’t taken care of and laundered correctly, it can damage both the fluorescent fabric finish, and the overall effect of the reflective stripes. If this happens, your work clothing no longer meets the EN 471/ISO 20471 rating it had before, making it hazardous to wear. If you decide not to wash it, then grease and dirt buildup will have the same dampening effect on the reflective properties.

    • Always was hi vis clothing separately from other clothes, or together with other EN471/ISO20471 clothes.
    • Turn the products inside out before putting into washing machine.
    • Avoid detergents that contain optical whiteners.
    • Do NOT use fabric softeners or bleaching agents.
    • Ensure all zips are secured.
    • Follow the manufacturers general temperature guidelines.

    Following these simple steps will make your work clothing care for high vis much easier, and keep the garments in great shape! If your Hi Vis uses a GORE-TEX fabric, always tumble dry them at a low temperature, as this helps to “reactivate” the weather resistant properties.

    FR Clothing Care

    For soiling on FR garments, pre-soaking in conditioned warm water, with use of a stain remover* to get rid of soiling. Also bare in mind that hard water can precipitate soap, resulting in a build-up of magnesium salts and calcium. These can actually have an adverse effect on the clothing, adding fuel to the combustion process. As with the high vis clothing, always turn your FR clothing inside out prior to washing.

    Fill your washing machine no more than two thirds of its capacity to allow the clothing to move around free and help the cleaning process. Always launder FR clothing separate from other clothing types, on a “normal” or “cotton care” cycle at a temperature of 60c maximum. For FR clothing care, you can use a regular home laundry detergent.

      • Always avoid using starch or fabric softeners.
      • Never launder FR clothing with chlorine bleach, or liquid nonchlorine bleach.
      • If contaminants remain after a wash, the FR clothing may require professional laundering.
      • Never “over dry” your FR clothing.

    FR clothing comes in two types – Inherent and treated fabrics. Treated fabrics will degrade with washing, but inherent FR products are protective at the fibre level, so they are far better lasting in comparison.

    Waterproof clothing care

    waterproof clothing careWaterproof clothing is normally treated with a coating which gives them their protective qualities. Before laundering, ensure all loose soiling is removed, and close all the zips, flaps and pockets on the product. Ensure also that you avoid detergents and fabric softeners, as they can break down the fibres of the products itself, with each wash making the product less and less effective against foul weather.

    • Always use specific cleaners designed for technical outerwear.
    • Check that the detergent compartment in your machine and ensure it is clean/empty.
    • Wash waterproof clothing with only 2-3 other waterproof items at a time.
    • Use a wash and rinse cycle of 30c for best results*
    • Leave products to air dry, or if the care instructions say otherwise they can be tumble dried.

    Treated waterproof fabrics will degrade over time, and if you find your trousers or jacket is absorbing rather than repelling, the writing may be on the wall and you might want to invest in a new jacket. There are products available which can “re-proof” the fabric. If after treating the product still leaks, its definitely time to look for some new Waterproof clothing.

    EN 343 Waterproof Clothing Explained

    en343-explained


    When its time to face the elements, it’s always important that your work clothing can offer you the right level of protection. When it comes to rain, you’re going to want to take advantage of clothing which is fully waterproof. Not to be confused with products that are water resistant or water repellent – fully waterproof work clothing meets EN343 standard, and differs from its counterparts, in terms of how it keeps you protected.

    Waterproof ClothingWater resistant clothing is able to resist penetration from water exposure to a certain extent, but will not be effective in heavy foul weather conditions, whereas products which are repellent are not so easily penetrated under exposure to water, and are usually hydrophobic in nature. Repellent products will usually be treated to bead water off of the surface, but water can still get into certain areas such as seams, zips and pockets.

    Products which fall into the EN 343 foul weather protection category, are defined by two attributes –

    • Water penetration
    • Water vapour resistance

    These values are split into three classes from 1 through to 3, and accompany the EN343 pictograph as illustrated:

    EN343 Pictograph
    The EN343 Pictograph

    Below you can see a breakdown of the three levels of water penetration resistance for En 343 foul weather clothing. 8000 Pa (Pascal units) equates to 1.16 pounds per square inch (PSI).

    Water Penetration Resistance Class
    1 2 3
    Test on fabric ≥ 8 000 Pa, before pre-treatment ≥ 8 000 Pa , after pre-treatment ≥ 13 000 Pa, after pre-treatment
    Tests on seam, before pre-treatment ≥ 8 000 Pa ≥ 8 000 Pa ≥ 13 000 Pa

    1 mVc (meter water column) = 10 000 Pa

    The table below shows the attributes of vapour resistivity, based on the operating temperature, and the number of hours which the garment can withstand vapour penetration.

    The preferred working hours based on the garment’s water vapour resistivity Class
    Operating temperature °C 1 2 3
    25 60 105 205
    20 75 250
    15 100
    10 240
    5

    “-” Means that working time is not limited.

    As with all types of protective clothing, EN 343 certified waterproof clothing garments should be looked after in the correct manner, in order to maintain their protective qualities. For maximum effectiveness you must always ensure that the products are well fitted and closed fully to reduce any chance of water penetration, and that the fabric itself is kept clean, as dirt can negatively impact the effectiveness of the protection. It’s always important that foul weather protective clothing and accessories are stored in dry and well ventilated areas. As with all clothes, it is also recommended to follow any fabric care instructions applicable to individual items, to help further maintain their protective qualities.
