Produced or Expanded Foam samples should represent as closely as possible the foam reaching the designated discharge area.

Collecting samples from nozzles, monitors and overhead sprinklers
Collect sample from point of impact in the discharge area.

Collecting samples from Foam Pourers
Insert sample container into the edge of produced foam stream and take sample.

Remove standing columns of water
Before taking a sample activate the foam system long enough to remove standing columns of water (which otherwise would contribute to a dilute produced foam sample).

Sample when the system is in equilibrium.

Sample bottles and labels
Samples should ideally be provided in clean tightly sealed polythene bottles and be labelled with the following information:

• Type of Foam Concentrate/Produced Foam e.g. 3% AFFF−LF
• Name of Company
• Date of Sample Taken
• Sample Source
