Vêtements de travail et équipements de protection individuelle. Propriétés antistatiques et critères d'acceptabilité en zone ATEX

Abstract : Explosion risk assessment specifically involves considering the antistatic properties of work clothing (WC) and personal protective equipment (PPE), which may be used in explosible atmospheres (ATEX). Static electrical discharges from this equipment are indeed likely to constitute an inflammation source for an ATEX gas/vapour or dust. There are separate regulations and standards on ATEX and PPE, so a study was conducted by INRS in cooperation with INERIS. Laboratory tests (based on current standards and additional experimental method) were conducted to assess the difficulty of evaluating the dissipation properties of WC and PPE. Analysis of the results reveals that current operating procedures and requirements are insufficient for overall antistatic characterisation of a WC or PPE. Not only the design (seams, pockets, logos, etc.), but also the nature and thickness of layers worn beneath the equipment play a preponderant part in dissipating electrical charges. Similarly, wear and repetitive washing cycles have a negative impact on initial performance. The long-term aim is to be able to stabilise a method and its related criteria to allow overall validation of the equipment for use in an ATEX zone.
