1. 1 Workshop C “Future challenges for PPE standardization“ Determination of Workplace Protection Factors (WPF) for Respiratory Protective Devices – A PEROSH Project 4th EUROSHNET Conference 26–28 June 2012 Helsinki (Espoo), Finland

2. PEROSH WPF Factors for RPD Seite 2 PEROSH Partners in WPF-Project

3. PEROSH WPF Factors for RPD Seite 3 Background RPD must be: Suitable for environment, the task and the wearer Adequate for the concentration of contaminant Selection has been based on nominal protection factors (NPF) Respiratory Protective Devices (RPD) must be correctly selected to achieve optimum wearer protection

4. PEROSH WPF Factors for RPD Seite 4 NPFs can be set for RPD based of total inward leakage requirements in standards Source: EN 13274-1 Nominal Protection Factors NPF = Indicates the highest expectable level of protection under laboratory conditions using a standard protocol with possible instructions and interventions

5. PEROSH WPF Factors for RPD Seite 5 The Assigned Protection Factor (APF) is derived from available NPF data and is the expectable protection level in a real working environment. Assigned Protection Factors These factors do not always reflect the real protection and are derived in different ways within Europe and across the world Dilemma: Different approaches for setting up workplace related protection factors are used, e.g. by multiplication with safety factors, workplace measurements… (lack of common concept)

7. PEROSH WPF Factors for RPD Seite 7 ● Development of measurement strategy and method ● Measurements on real work places ● Develop and deliver RPD Programme training ● Re-measure RPD performance on real workplaces ● Assessment of the efficiency of training measures by comparing before and after situation Objectives

8. PEROSH WPF Factors for RPD Seite 8 Project Workflow

9. PEROSH WPF Factors for RPD Seite 9 ●Harmonisation of work place related protection factors on European level (  Comparability, common basis for taking safety measures) ●Validation of the efficiency of targeted education & training programs ●Support for the (retrospective) investigation in health related diseases Benefits
