The producer of the material guarantees min. 5 cycles before any re-impregnation when the laundering instructions are followed. • Impregnation efficiency in real conditions may differ from the measured laboratory results and is influenced by several factors. • Keep your garment clean. • For recovery of the treatment we recommend additional drying in the tumbler at temperature 70 °C for 15 minutes ! Perform the additional drying on closed garment from the face side after each maintenance (washing + drying). 4 Clothing protective function and the complete list of harmonized standards used when designing this PPE: The protective clothing can be ONLY used as upper part on foundation garment. Foundation garment which melts during heat flux of electric arc MUST NOT be used which means foundation garment made of artificial fibers, e. g. Polyamide, polyester, acryl. Protective clothing – outer clothing to be worn with underwear – protects the wearer´s body except hands and feet from heat and /or flame. It is also electrostatic dissipative clothing, used as a part of a total earethed system, to avoid incendiary discharges. The clothing is also used for the protection against unfavorable weather (for example rain, snow), fog and earth water content as well as against cold environment (only version with removable inner lining ARAFELT). Jacket protects against thermal hazards of an electrical arc (but not against eletric shock hazards). Protective clothing ( typ 6, for limited repeated use) made of art. 1100/FC material protects beforer potential exposure by light spraying, liquid aerosol or low pressure, low spraying volume of by small amount of diluted chemicals (acids, bases). SN EN ISO 13688:2014 - Protective Clothing – General Requirements (EN ISO 13688:2013) SN EN 1149-5:2008 - Protective Clothing – Static Electricity Clothing (EN 1149-5:2008) Flame-retardant clothing is designed for professionals in the energy industry or workers in gas and petrochemicals industry and fulfill folowing requests: 5 SN EN ISO 11612:2015 - Protective clothing – Clothes against heat and flames (EN ISO 11612:2015) • Limited flame spread with/without lining A1,A2 • Convective heat: - with lining: B2 - without lining: B1 • Protection against water penetration and water vapour resistance: - with lining: W32 - without lining: W33 SN EN 343:2004+A1:2008/Opr. 1:2010 - Protective clothing – Protection against rain(EN 343:2003+A1:2007/AC:2009) • Resistance against water penetration WP with lining, without lining: level 3 • Water vapour resistance Ret: with lining level 2 without lining: level 3 SN EN 342:2004/Opr. 1:2008 Protective clothing – ensembles and garments for protection against cold(EN 342:2004/AC:2008) Level of protection – achieved effectiveness of protective clothing • Effective thermal insulation Icler 0,42 m2.K/W • Air permeability level 3 • Resistance to water penetration level 2 (only version with removable inner lining ARAFELT) 6 IEC 61482-2:2009 - Protective clothing against the thermal hazards of an electric arc Resistance to thermal hazards of an electric arc – box test: • Class: 2 • Prospective electric arc current: 7 kA • Arc duration: 500 ms • Voltage: 400 V SN EN 13034+A1: 2009 Protective clothing against liquid chemicals - type 6, material - art. 1100/FC.(EN 13034: 2005+A1:2009) Protective clothing against liquid chemicals - type 6 (material - art. 1100/FC) was tested and corresponds to the following requirements: - Repellency to liquid chemicals: - 30% H2SO4 level 3 - 10% NaOH level 3 - o-Xylen level 2 - Butan-1-ol level 2 7 Clothing service life Duration of the protective clothing using is not fixed. Expected service life is within the range from 4 to 7 years in case of average utilization. It is protective clothing which means that it can be damaged during some working activity. In such case the following steps have to be done: • Clean the clothing according to the instructions • Ensure skilled revision of the clothing by a responsible person (producer, skilled distributor, or skilled person of a particular fire station) • In case of need repair it (to ensure safety the clothing should be repaired at the PRODUCER or a trained person) • In case of excessive damage and failure of the protective properties of the clothing when the repair is not worthwhile, we recommend to put out of use - Resistance to penetration of liquid chemicals: - 30% H2SO4 level 3 - 10% NaOH level 3 - o-Xylen level 2 - Butan-1-ol level 2 - Abrasion level 6 - Tear strength level 5 - Tensile strength level 6 - Puncture resistance level 2 - Seam strength level 6 The protective garment achieves the above mentioned protection features only if jacket and trousers are used at the same time and removable lining is part of the suit. Removable lining can not be used separately. Protective clothing must permanently cover all materials without protective properties during use. All closing elements must be properly closed! 8 Maintenance: Iron at maximal temperature 110 °C, carefully with steam. • We recommend delicate washing at 40 °C • All closures (zippers, press buttons, velcros, buttons, carabines) must be properly closed to avoid abrasion • Before washing and drying is necessary to remove neoprene knee pads! • PH of washing bath must not be higher than 9. • Do not use detergents with bleaching effects. • Optimal level of machine loading is 2/3, with maximum possible water level and lower spinning speeds. • If the garment has removable insert, always wash the outer parts separately from inserts. If inserts are not soiled, remove them and wash just the outer parts to prevent unnecessary wear of moisture and thermal barrier. • Do not use any softeners! • Line dry is optimal • Using a tumbler dryer, dry at lower temperature. We recommend drying in two cycles (face and back sides) 2 x 45 minutes. • A dryer should be filled at 2/3 of its capacity. (f.e. for drum of 13 kg put dry garments with weight of 10 kg) • If the garment is damp, we recommend to hang it to dry • To recover the treatment we recommend additional drying at 70 °C for 15 minutes!! Perform the additional drying on closed garment from the face side after each maintenance (washing + drying). 9 • Professional wet cleaning. Ordinary cleaning procedures. Finally we would like to draw your attention to a fact that NOMEX®material is as other chemical materials sensitive to direct daylight. To eliminate mechanical and visual abrasion of the outer material of the garment it is essential to observe right laundering procedures, eventually timely done re-impregnation. We are absolutely convinced that the most sensitive part at laundering is the time, the temperature and loading of the washing and drying process. We can say that excessive temperature and over drying can result in excessive shrinkage. We absolutely recommend keeping an evidence list of the clothing service and maintenance (Appendix 1 – see our web pages Decontamination (Disinfection) : • Intervention clothing infected by biological material must be treated with hydrogen peroxide and peracetic acid-based concentrates activated during machine washing. • Do not use chlorine-based products. • Recommended disinfection agents are suitable for white, as well as color textiles, except wool and silk. Their utilization is in accordance with European microbicide standards EN 1650 and EN 14476. • Disinfection agents are effective at 40 °C and a longer washing cycle of at least 20 minutes. • The exact dosage will be specified by your chemicals supplier based on the intervention clothing types. 10 Washing and decontamination agents that can be used for intervention clothing are in the chart bellow: Storage: Storage has no specific requirements Protect the clothing from direct sunlight and UV radiation Clothing protective packaging: PE bag, cardboard User notification: • In case of accidental soiling with a liquid chemical or flammable fluid when using in the environment with the excessive risk of exposure to fire and/or heat or when under excessive heat load when heat is strongly felt on skin, it is necessary to immediately retreat and remove and clean the clothing, or decommission it if necessary. • A person wearing protective clothing that dissipates static electricity charge must be properly grounded. Resistance between such person and ground must be less than 108 W, by using, for example, proper footwear. The clothing must not be unfastened or removed near flammable or explosive environment or when working with flammable or explosive agents. The clothing must not be used in the oxygen-enriched atmosphere without a prior approval of a responsible safety technician. The clothing's static electricity protection properties could be affected by its wear, tear, washing, and soiling. When in use, the static electricity dissipating protection clothing must constantly cover all materials that do not have such properties. • When using this clothing as a protection against the thermal hazards of an electric arc i tis necessary to consider actual working conditions. Differences from parameters specified in IEC 61482-3 can cause serious circumstances. • Thermal isolation measured in compliance with SN EN 342 may decrease after cleaning! 12 CSN EN 342 Parameter levels The protective value of the measured efficient thermal insulation or the final efficiency of the thermal insulation of a clothing set represents a combination between the surrounding air temperature and the levels of activities performed by the person (production of heat through body chemical reaction - metabolism), (see tables B. 1 and B. 2). Levels shown in the B. 1 table correspond with a user who stands, and levels shown in the B. 2 table correspond with a user who performs light or easy activities. For each level the temperature is calculated at which the body may be maintained under neutral conditions and for an unspecific time (8 hours), and the lowest temperature during which the user may carry on for 1 hour together with acceptable body cooling process. Values are based on conditions where the air temperature equals to average radiation temperature, with relative air humidity approximately 50%, the airflow speed (wind speed) is between 0.3 m/s - 0.5 m/s and walking speed is approximately 1.0 m/s. NOTE: The adequate insulation level of the entire body may not be sufficient to eliminate cooling of sensitive body parts (for example hands, legs, face) which may result in frostbite. Protection of hands against frostbite is addressed in EN 511.

Higher wind speeds will increase values in B. 1 and B. 2 tables due to the wind chill factor (see ENV ISO 11079).
