Control measure knowledge

Strategic actions

Fire and rescue services should:

Ensure that fire and rescue service managers who are likely to be in command of an incident involving hazardous materials and/or environmental risk, or are likely to perform the specialist advisory role of hazardous materials advisor (HMA), receive specialist environmental training. This training should place emphasis on larger-scale incidents where there is significant environmental risk
Consider mobilising or involving a Hazardous Materials Advisor (HMA for any incident with the potential to pollute the environment, not only those incidents involving hazardous materials. See section 3.3, Environmental Protection Handbook
Identify triggers where the local environment agency should be informed or where advice should be requested
Secure access to more detailed advice from scientific advisers or from the CHEMSAFE service provided by the National Chemical Emergency Centre (NCEC)

Tactical actions

Incident commanders should:

Contain the spill
Seek guidance from environment agencies before any attempt at dilution
Not flush spillages down drains without approval from:
- The local environment agency
- Sewerage company
Ensure that if detergents or other chemicals are added to spillages to assist with clean up or treatment the resulting mixture is not to be flushed down drains
