How HSE uses population data for hazard mapping and modelling

A session at 45th Annual Society of Cartographers Summer School

2:45pm to 2:45pm (GMT)

The UK’s Health and Safety Executive (HSE) is responsible for the regulation of almost all the risks to health and safety arising from work activity in UK. The HSE has a duty to protect people's health and safety by ensuring risks in the changing workplace are properly controlled. The Health and Safety Laboratory (HSL) provide support to HSE for these duties. This includes developing risk assessment techniques and tools for use in major accident hazard modelling and societal risk estimation.

HSL host, maintain and run the HSE’s National Population Database (NPD) tool. This tool is being used to provide a valuable new dimension to population density and distribution estimation. The NPD provides population data from a local to a national level for England, Scotland and Wales. Populations are available on a 100m grid or on an individual building level and include residential, workplace, retail, transport system, leisure and sensitive populations. This detailed population breakdown allows for a new level of analysis detail, including the identification and estimation of populations that may be more susceptible to harm or hard to evacuate. The NPD has been used for a range of tasks including detailed societal or ‘off site’ risk calculations, identification of certain ‘at risk’ populations and scenario planning. This paper will present some recent case studies where the NPD has been used and will discuss how this has aided HSE risk assessment work.
