TEGERA's Guide for Chemical Resistant Gloves

Use our chemical protection guide or contact one of our sellers and get help in finding a suitable glove for protection against the relevant chemical mix.

Prévenir l'exposition aux produits chimiques : Utiliser les bons gants de protection

En manipulant des substances chimiques ou huileuses sans protection adéquate des mains, vous vous exposez à des risques de lésions de la peau mais également du système nerveux et des organes vitaux. Ces substances chimiques peuvent également être à l'origine d'irritations, d'hypersensibilité et de corrosion de la peau. Consultez notre guide de protection contre les substances chimiques ou consultez-nous pour choisir vos gants.

L'ensemble des gants de protection chimique d’Ejendals ont été testés et certifiés conformes à la norme EN 374 relative aux gants de protection contre les produits chimiques et les micro-organismes. Les gants de protection contre les produits chimiques sont conçus pour un usage journalier, voire pour des périodes plus courtes.

Utiliser le Guide de protection chimique

Si les produits chimiques utilisés et l’environnement de travail sont connus, notre Guide de protection chimique peut vous aider à identifier les gants adaptés aux applications les plus courantes.

Cette option convient si :

  • Vous savez quels produits chimiques sont manipulés
  • Les fiches de données de sécurité (FDS) sont disponibles
  • Le processus de travail et les conditions d’exposition sont clairement définis

Demander une évaluation de protection chimique

Si votre application est plus complexe ou nécessite une expertise approfondie, nos spécialistes peuvent évaluer vos conditions spécifiques et recommander les gants les plus adaptés.

Cette option est recommandée si :

  • Plusieurs produits chimiques sont utilisés simultanément
  • Les conditions d’exposition sont complexes ou incertaines
  • Vous ne savez pas quelle solution de gants est la plus appropriée

BREAK-THROUGH-TIMES (BTT) FOR A SELECTION OF COMMON CHEMICALS

Break-through-time (BTT) is the time when a chemical is considered to have permeated (passed through) a material. It depends primarily on the material and secondarily on the thickness (and other factors). All data refer to full contact with the chemicals at room temperature, and need to be adjusted for actual conditions and additional risks.

The BTT data in this chemical protection guide originate from combined data from laboratory tests and our internal database. The BTT values are calculated from best-fit to experimental points and rounded downwards to closest EN374 Class (and two additional lower levels (0 – 5 min) that might be useful when selecting gloves for work operations of very short duration).

THINGS TO CONSIDER WHEN CHOOSING CHEMICAL PROTECTION GLOVES

  • A glove that gives good protection against a certain individual chemical may give very poor protection against others or a mixture of chemicals.
  • As a rule, chemical protection gloves are intended for single-day use. They must not be re-used.
  • A used glove is chemically contaminated and there is a risk that the skin will be exposed to harmful substances when it is handled.
  • Higher temperatures shorten the time it takes for the chemical to break through.
  • Thicker materials generally mean longer breakthrough times (BTT).
  • At Ejendals, for gloves consisting of multiple layers (liner etc), we denote the effective thickness of the chemical protection layer with an asterisk (*). It is this thickness we use in our estimations of BTT for a certain combination of glove model and chemical.
  • Once a chemical has been absorbed, it continues to break through (permeate) the protective glove.
  • Permeation through a protective glove takes place at the molecular level and is therefore not visible to the naked eye.
  • Even the best gloves lose their protective properties if they are mechanically damaged or if the chemical has broken through the material.
  • Strongly corrosive chemicals can destroy the glove material by breaking it down before the specified breakthrough time.

WHAT IS WHAT?

  • PERMEATION is a process whereby the chemical is absorbed into and passes through the glove material at a molecular level.
  • PENETRATION involves the chemical moving through pinholes and other imperfections in the glove material.
  • DEGRADATION is when the glove material’s physical resistance deteriorates under the influence of a chemical.

MIXING CHEMICALS CAN HAVE UNEXPECTED RESULTS

Two chemicals with known characteristics can produce unexpected effects when mixed. Since the number of chemicals marketed is huge, it is virtually impossible to test all conceivable combinations of them. Models do exist for estimating combined effects on the basis of what is known about the component chemicals. However, they presuppose that data is available and that the various chemicals involved have the same mechanisms of action. This means that the models can only be used for groups of chemicals that act in a similar way – not for the complex mix of chemicals that we are exposed to in reality.
