### Laboratory Support, continued

When agreeing to provide laboratory support:

- The ASR or PRL will distribute samples to all assisting MSLs.
- A log should be kept by the PRL/MSL and should include the number, type, and volume of samples and the required data turnaround times. This information may be recorded in a laboratory notebook or the form provided in Appendix C of the WLA-RP.
- Accepting samples does not obligate a laboratory to provide support throughout the life cycle of an incident. If an MSL determines it can no longer provide analytical support, the MSL designee should contact the PRL to request that sample shipment be stopped or rerouted back to the PRL or to another MSL.
