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

NPFs can be set for RPD based of total inward leakage requirements in standards

NPF = Indicates the highest expectable level of protection under laboratory conditions using a standard protocol with possible instructions and interventions
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)

● 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
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
