An Agency of the Health and Safety Executive
Health and Safety Laboratory
• Founded in 1911 to study explosions in coal mines
• Remit increased many times since: Health & Safety at Work Act 1974 An Agency of HSE since 1995; supports HSE mission to
protect health and safety in the workplace
Large laboratory and test site at Harpur Hill, Buxton
An Agency of the Health and Safety Executive
Health & Safety Laboratory
• HSL is Britain’s leading industrial health and safety facility
• Experience across all sectors, including:– Fire & process safety – Computational modelling– Mechanical engineering– Exposure control
• Key Facilities– Largest impact track in Europe– Test range – Drop-test rigs– Anechoic chamber– Biomechanics lab
An Agency of the Health and Safety Executive
• HSE’s main concern is with people
• Demographic modelling work came from HSE’s requirement to have a greater knowledge of the density and distribution of population
• This included estimating harm to groups of people from major hazard sites – societal risk
Background
This led to the development of the NPD
An Agency of the Health and Safety Executive
• HSL have developed a tool to provide population density and distribution estimates for UK - NPD
• Available for England, Scotland, Wales and Northern Ireland
• National to local levels of detail
• NPD is owned by HSE, and hosted, run, developed and maintained by HSL
The NPD
An Agency of the Health and Safety Executive
Populations and Resolution
NPD - Population Data for England Scotland, Wales and NI
Populations include: Residential (day/night) Sensitive populations - hospitals - care homes - prisons - childcare -schools - colleges Workplace Leisure Transport (terminals and networks)Resolution - 100m grid, postcodes, individual building
• NPD provides vulnerability, location, time differentiation
An Agency of the Health and Safety Executive
• GIS based tool that uses a wide range of data sets to produce a variety of population estimates
• Data sets used include:
Ordnance Survey (OS) PSMA
digital mapping products
addressing, infrastructure and
mapping data
Census data – residential and
workplace data
Government data – schools,
child-care and hospitals
Commercial data sets
retail floorspace
Inter Departmental Business Register (IDBR) – workplace details
NPD Methodology

Spatial Extent
• Population in an area of interest
An Agency of the Health and Safety Executive
Indoor
Night time residential = 13,000 Day time residential = 5,500
Indoor/outdoor
Workplace = 2200 Sensitives = 2,000
Outdoor
Peak time road population = 750

Case Study 3 - Emergency Planning
• Office for Nuclear Regulation have an ‘incident suite’ used to monitor incidents at nuclear sites
• HSL developed customised application to view nuclear site details and estimate populations at risk
• Identify vulnerable populations

• Major NPD Updates
Migration from AL2 to AddressBase, 2011 Census
• Recently completed layer updates
Transport Hubs, Care Homes, Visitor Attractions
• Specific layer updates currently underway
Childcare, Residential
• Future Developments
Railway layer, Pedestrian layer, Transient populations, 24/7 populations
