Introduction

Part 1. Overview of the HPA and CRCE• Background and Structure of HPA CRCE

• Functions of CRCE

Part 2. Chemical Incident Response• Acute Incidents

• Chronic Environmental Public Health Concerns

• HPA Resources

Part 1. Overview of HPA CRCE

Health Protection Agency

• Independent non-departmental government body, created from existing organisations on 1st April 2003

• HPA Act 2004: • “Protect the community (or any part of the community) against

infectious diseases and other dangers to health”

• Civil Contingencies Act 2004:• Category One responder

• Provide expert support and advice:• Infectious disease, radiation, chemicals, poisons, emergency response

• 24 hour service

Part 2. Chemical Incident Response

Chemical Incidents

“Any event leading to exposure of two or more individuals to any substance resulting in illness or potentially toxic threat to health.” Hill and O’Sullivan (1992)

Examples:• Fire• Explosion• Release / Spillage• Water pollution• Food contamination• Transport-related

HPA Role in Chemical Incidents

• Undertake assessment of public health risk

• Provision of advice and support to first line responders

• PCTs and Directors of Public Health

• other agencies (e.g. local authorities, NHS, emergency responders etc)

• the public

• Clinical Treatment Advice via National Poisons Information Service (NPIS) – through TOXBASE website and 24hour phone number

Incidents Reported to CRCE in 2010

Chemical Incidents – Who Responds?

• Blue light services deal with the initial incident.

• A&Es deal with casualties.

• Public health aspects are dealt with by the HPA & PCT. The HPA is a Category 1 Responder under the Civil Contingencies Act 2004.

• NHS Direct, GPs, PCTs deal with queries regarding individuals’ health.

• Other stakeholders likely to be involved: Local Authority, Environment Agency, Food Standards Agency, Health and Safety Executive, Met. Office, Media.

Fires

Chemical Fatalities

Air Quality Cell (AQC)

• A virtual multi-agency advisory group which can be convened during a major incident to co-ordinate air monitoring and modelling.

• Partners include EA, HPA, Met Office, HSL, FSA + others.

• It aims to provide timely (interpreted) air quality and air modelling information to the Science and Technical Advice Cell (if formed), or to a multi-agency group.

Chronic Environmental Public Health Concerns

Advice and support is also given with respect to chronic incidents.

Example areas of support to local authorities:•Contamination of private drinking water supplies•Health concerns from industrial emissions•Contaminated school play areas/allotments •Health implications of nuisance dust•Fuel spillages affecting residential properties•Alleged cancer clusters near industrial premises
