Escolher o tecido mais adequado para seu programa de vestimentas de proteção térmica depende do conhecimento dos riscos a que seus colaboradores estão expostos. Também, depende das normas aplicáveis à exposição a estes riscos. Assim, três passos são necessários para garantir a escolha certa dos diferentes tipos de tecidos.
Riscos térmicos apresentam características diferentes e se portam de maneira distinta. Por esta razão, os resultados de testes de riscos diferentes não podem ser extrapolados de forma a buscar uma correlação entre eles, bem como do desempenho em uso real. Os resultados de testes de fogo repentino não devem ser substituídos por um teste de arco elétrico quando da avalição de diferentes produtos. Cuidado com fabricantes de tecidos que buscam apresentar correlações entre estes dois tipos de riscos.
Várias normas foram elaboradas para os riscos de Arco Elétrico e Fogo Repentino. Para o Arco Elétrico, a ASTM criou a norma F1959, que quantifica o valor de um arco elétrico. A NFPA 2112 foi criada para avaliar o risco potencial a que estão submetidos os trabalhadores envolvidos em ambientes onde exista o risco de fogo repentino.
Este passo gera a possiblidade de nos certificarmos que os resultados obtidos são corretos e realizados da forma que relatem a realidade do produto testado. Não há substituídos aos laboratórios independentes de credibilidade internacional.
Ao identificar a probabilidade e a gravidade de todos os riscos relevantes no trabalho, as equipes podem direcionar melhor sua abordagem de segurança e determinar qual tecido de proteção pode fazer a diferença para salvar vidas.
The intense energy and short duration of an electric arc represents a unique exposure — one that requires flame-resistant garments durable enough to withstand temperatures that approach 35,000 °F while providing the wearer with protection to self-extinguish when the arc flash event is over (in tenths of a second) and better insulate/protect against a second degree burn through the fabric.
Once ignited, regular cotton or poly/cotton work clothes could continue burning even after the source of the ignition is removed. Westex arc flash protection fabrics, however, will self-extinguish and provide guaranteed flame resistance for the life of the garment.
A type of short-duration fire that spreads by means of a flame front rapidly through a diffuse fuel, such as a dust, gas or the vapors of an ignitable liquid, without the production of damaging pressure.
The primary consensus standard (NFPA 652), the key NFPA standard governing PPE use in combustible dust environments, states employers “shall address PPE, including flame-resistant garments” for operating and maintenance procedures as required by an appropriate workplace hazard assessment outlined in NFPA 2113. Combustible Dust includes a Flash Fire Hazard and FR clothing is required.
Workers in labs face dangerous liquid chemicals and/or solvents at atmospheric pressures, such as corrosive liquids, toxic liquids and absorption and ignition of flammable liquids.
For more than 40 years, heavyweight flame-resistant cotton fabrics have been utilized by the steel industry as secondary protective clothing for workers doing routine tasks in steel processing. Secondary protective clothing is defined as “protective clothing for continuous wear during work activities in designated locations in which intermittent exposure to molten substance splash, radiant heat and flame sources are possible.”
Construction, utility, police, emergency medical services, fire fighters and other workers are routinely exposed to the hazards of low visibility — such as motor vehicles and heavy equipment — while on the job.
Hi-visibility fabrics meet specific requirements on how the reflect light so your workers can be seen in those low visibility situations.
Superar os padrões da indústria é essencial para o nosso compromisso global de fornecer tecidos de proteção superiores, resistentes a chamas e com classificação de arco elétrico (FR/AR). Em todo o mundo, a Westex vai além dos requisitos estabelecidos para situações de exposição não planejada a riscos. Esta visão geral não tem a intenção de substituir tais normas, mas sim de servir como uma breve descrição. Recomendamos que você consulte as normas na íntegra nos sites das respectivas organizações.
NFPA 2112 is meant to provide the specifications for the minimum design, performance, testing and certification requirements and test methods for flame-resistant garments used in areas at risk of thermal exposure from fire. The use of these garments is with the intent of not contributing to the burn injury of the wearer, providing a degree of protection and reducing the severity of burn injuries resulting during egress from or accidental exposure. You can trust that many Westex fabrics are NFPA 2112 certified – contact your regional market manager for more information.
NFPA 70E is meant to provide a practical, safe working area for employees relative to the hazards that arise from electricity use. This standard addresses electrical safety-related work practices, maintenance requirements and other administrative controls for workers whose job responsibilities involve interaction with energized electrical hazards that could result in injury or fatality due to shock, arc flash and arc blast. The majority of our fabrics provide NFPA 70E category 1 or 2 protection. Reach out to your regional market manager for any additional questions or resources related to 70E.
ANSI 107 is used as a guide for the design, performance specifications and use of high-visibility and reflective apparel, like vests, jackets, bib/jumpsuit coveralls, trousers and harnesses. If a garment meets this standard, it can be worn at any point in a 24-hour day and allow its users to be seen by fluorescent and retroreflective materials. Many of our hi vis yellow fabrics—DH, DH Air™, Polartec® FR and UltraSoft®—are certified to ANSI 107. Contact your regional market manager for additional information.
CGSB 155.20 a national standard of Canada states the minimum requirements and test methods for performance of protective workwear worn for protection against unplanned exposure to hydrocarbon flash fire and optionally steam and hot fluids.
CSA Z96 specifies performance requirements for color, retroreflection, and minimum areas as well as the configuration of materials of high-visibility safety apparel intended to provide the wearer with increased conspicuity under both well-illuminated or low-light/dark work environmental conditions. According to this standard, certified apparel should be capable of signaling the user’s presence visually. This standard is in technical harmony with the US standard, ANSI 107, therefore many Westex fabrics that are ANSI 107 certified are simultaneously CSA Z96 certified.
ISO 11611:2015 specifies minimum basic safety requirements and test methods for protective clothing including hoods, aprons, sleeves, and gaiters that are designed to protect the wearer’s body including head (hoods) and feet (gaiters) and that are to be worn during welding and allied processes with comparable risks. For the protection of the wearer’s head and feet, this International Standard is only applicable to hoods and gaiters. This International Standard does not cover requirements for feet, hand, face, and/or eye protectors.
This European standard specifies material and design requirements for electrostatic dissipative protective clothing, including hoods and caps, used as part of a total earthed system, to avoid incendiary discharges where the minimum ignition energy of an explosive atmosphere is no less than 0.016 mJ. Our DH, Synergy Pro and select styles of UltraSoft fabrics meet this standard. Reach out to our international market manager to learn more.
This part of IEC 61482 specifies test method procedures to test materials and garments intended for use in heat and flame-resistant clothing for workers if there is an electric arc hazard. A directed and constrained electric arc in a test circuit is used to classify material and clothing in two defined arc protection classes. Our DH, DH Air, Polartec FR and UltraSoft fabrics meet Class 1 of this standard. Reach out to our international market manager to learn more.
This international standard specifies requirements for high visibility clothing that’s visually capable of signaling a user’s presence. This clothing is intended to provide conspicuity of the wearer in any light condition when viewed by vehicle operators or other equipment during daylight hours and under the illumination of headlights when it is dark. Our DH fabrics currently meet this standard. Reach out to our international market manager to learn more.
This British standard specifies the minimum performance requirements for limited use and re-useable limited chemical protective clothing against liquid chemicals (Type 6). Type 6 is intended for use in cases where the risk has been assessed as low and a full liquid permeation barrier is not necessary—when wearers are able to take timely action when their clothing is contaminated.
Limited performance chemical protective clothing is intended for use in cases of a potential exposure to a light spray, liquid aerosols or low pressure and low volume splashes. Westex now meets this standard with a non-PFAS finish for its DH, DH Air and UltraSoft fabrics. Reach out to our international market manager to learn more.
This standard specifies the technical requirements, test methods, inspection rules, marking, etc., of electrostatic protective clothing used in places where electric shock, fire, and explosion may be caused by static electricity.
