Case Study - The Bristol Port Company, Avonmouth Docks

Project: Installation of Condensed Aerosol Fire Suppression in HV Transformer and Switch Rooms

Client: The Bristol Port Company – Avonmouth Docks

Service: Condensed Aerosol Fire Suppression

Clients challenge:

Mechanically operated Gas Suppression System were unsafe for the following reasons:

  • Utilised CO2 Gas which is an asphyxiant
  • Cylinders were overdue their hydraulic pressure test
  • Unsafe means of deactivating the system

Limited space available.

Project goal:

  1. Increase the safety of the environments.
  2. Reduce wasted space.


Condensed Aerosol Suppression System resolved the safety issues in the following ways:

  • Removed stored pressure CO2 cylinders from site.
  • Condensed Aerosol is stored at atmospheric pressure, so no hydraulic tests were required.
  • Electrically operated means of deactivating the system were installed outside of the protected area.

Condensed Aerosol Suppression was mounted on walls at high level to minimise the waste of space taken up by the original CO2 gas cylinders.


Rhino Fire Control removed the obsolete mechanical CO2 gas suppression systems and replaced them with modernised condensed aerosol suppression systems.

The key benefits to the client are:

✔ Increased levels of personnel safety.

✔ Enhanced level of fire protection

✔ Reduced wastage of space

✔ Lower requirement for room integrity

✔ Lower maintenance costs

✔ 50% extra life-cycle compared to gas suppression
