Market Surveillance Authorities – PRISM

A series of seminars to inform Local Authority Regulatory Services (LARS) about changes and new developments in MSA Risk Assessment with the launch of PRISM.

PRISM is a new product safety risk assessment methodology intended for use by those market surveillance authorities and enforcing authorities in Great Britain with responsibility for consumer product safety. For GB authorities, PRISM replaces the EU Safety Gate risk assessment methodology (RAPEX) and should now be used in place of RAPEX for product safety risk assessment purposes.

PRISM builds upon the RAPEX methodology, and practitioners familiar with RAPEX should find much of PRISM to be familiar. However there are a number of differences, for example within PRISM:

  • Risk evaluation is included.
  • Risk Tolerability is a key feature.
  • Risk Triage is covered.
  • More consideration is given to people who may be at increased risk (compared to the general population).
  • The purpose of risk assessment and the relationship between risk assessment and non-compliance is made more explicit.
  • The product risk includes consideration of the total number of product items in use, as well as the risk presented by a single product item.
  • There is more explicit consideration of uncertainty.
  • Additional guidance is provided on a range of key risk-related topics.
Risk basics for PRISM – Introduction & Overview

A three-hour  webinar providing colleagues an opportunity to refresh on risk fundamentals and the principles that underpin all risk assessments. The session will also briefly introduce PRISM, how it works, and how it can be used when carrying out risk assessment.

This training has now taken place, a recording of the webinar can be found on Regulators Companion.


PRISM – Advanced

A programme of in person one day sessions that will introduce PRISM and work through the various elements of the new process and methodology in detail.

LARS will receive an in depth demonstration of how Prism works and what LARS need to do to use it effectively.

LARS will learn about application through a series of worked case studies, including applying the new PRISM toolkit.
