• Description:
  The UK Health and Safety Laboratory has developed a miniature respirable sampler to help gain a better understanding of the exposure of workers to hazardous substances when wearing respiratory protective equipment or helmets with visors in the workplace. This presentation reports results from a multidisciplinary and international study to characterise the performance of the sampler designed to fit within a face filtering particulate (FFP) type 2 or 3 mask. The light weight (4.5 g) miniature sampler (15 mm in length) has an omnidirectional inlet and is designed to collect the respirable fraction using a 90 pores per inch (PPI) polyurethane foam insert. Tests in a calm air chamber show that it meets the respirable convention and has a performance, when challenged with Arizona Road Dust, that is similar to the reference Safety In Mines Respirable Dust Sampler (SIMPEDS), commonly used in Great Britain. Manikin tests show that, when challenged to a sodium chloride aerosol, the sampler has a linear relationship with the photometric measurement traditionally used for inward leakage tests in both ambient and humid conditions. Volunteer tests demonstrated that it does not affect the protection provided by the FFP type mask and that it can fit comfortably within the three FFP 3 type masks tested. The talk will discuss the opportunities and measurement limitations for in-mask sampling in the workplace. [Description provided by NIOSH]
