Forensic Arson Laboratory

Please call the lab at 512-676-6801 or 512-676-6803 and make arrangements with laboratory personnel before coming to the lab in person. 

The FAL will be issuing final Analysis Reports on submitted cases approximately 6-8 weeks after analysis has been completed. You may still contact the lab for preliminary results, but by definition, these may or may not be the final official results. We appreciate your patience and cooperation during this indefinite period of time.

The Forensic Arson Laboratory receives evidence  Mon-Fri, from 8:30 a.m. to 4:30 p.m..  If you have a rush/emergency case that needs to be received outside of these hours, please contact the laboratory manager at 512-934-8422.  As always, please call and speak to a laboratory employee (512-676-6801 or 512-676-6803) before coming to the laboratory in person.

Your feedback is valued! Participate in the Forensic Arson Laboratory customer survey.

The Forensic Arson Laboratory turnaround time for fire debris analysis is, on average, 3-5 business days from date of evidence receipt.  However, due to accreditation compliances, each case must undergo a series of reviews before the final analysis report can be released in order to ensure the most accurate reporting. This means that a final analysis report may not be available for 4-8 weeks from date of receipt.  However, agencies may contact the lab via phone (512-676-6801) or email ( to obtain preliminary results. Please make sure to provide the agency case number and that it has been at least 5 days since the evidence was mailed to the lab. Note: for expedited returns of analysis reports, an emailed report can be requested by marking the appropriate box on the lab submission form.

Open records update: As of May 2, TDI only accepts open records requests sent by email through Requests may still be submitted by fax to 512-490-1021, by mail, or in person.

Forensic Arson Laboratory services are provided at no cost to the fire service and other law enforcement agencies in the State of Texas. Turnaround time is usually six days.

The laboratory is limited at this time to the analysis of arson debris for ignitable liquids used to accelerate a fire. Explosives analyses require instrumentation and expertise which is currently available from the Bureau of Alcohol, Tobacco, and Firearms (ATF) laboratory system; please do not send these types of cases to this laboratory. The ATF offices and laboratory phone numbers are all listed in the Arson Lab Evidence Collection and Submission Handbook. The Handbook contains information to assist with evidence questions that may arise. Contact the laboratory at (512) 676-6801 to request Handbooks or for further assistance.

Documents explaining the methods for analysis of evidence used by the Forensic Arson Lab are available to our customers. These documents include Standard Operating Procedures, Quality Manual and ASTM Standards. If you would like copies of any of these documents, please email the Arson Lab at with your request.  Please note that ASTM Standards {including those used at the Arson Lab, E1412 and E1618} are copyrighted materials. Special arrangements must be made with the laboratory to view these documents. Please refer to the ASTM website for more information.

Please refer to the Forensic Arson Laboratory Guidelines for Evidence for important information regarding the collection and submission of evidence.

Forensic Arson Laboratory Physical Evidence Submission Form

Since the Forensic Arson Laboratory primarily offers criminal case analysis, the Laboratory Submission Form is to be used only in Arson or other criminally related cases. However, the Forensic Arson Laboratory also offers quality control analysis. Any agency may send us a clean, empty can from their stock of metal cans used for evidence collection. We may then evaluate these cans to determine if they are suitable for evidence collection (i.e., contamination free). The Forensic Arson Laboratory offers this service as a courtesy to all submitting agencies and as such, requests CANNOT be made on the Laboratory Submission Form. Please use the Evidence Can Quality Check form for this type of quality assurance service. Evidence Can Quality Check Form

For your convenience, the submission form may now be filled out online before printing. Don't forget to sign the form after filling out and printing it. The form cannot be submitted online.

When shipping evidence, address the package to the attention of the Forensic Arson Lab. This ensures that the person who opens the box will be someone intended to be in the chain of custody and that the evidence will be stored in the vault immediately, once the courier's responsibility has ended. Address the package to:

State Fire Marshal's Office
ATTN: Forensic Arson Laboratory
7915 Cameron Road
Austin, Texas 78754-3803

Always use our physical address when shipping evidence to the lab, and provide a physical address on the "send to" section of the submission form. Courier services will no longer deliver to post office boxes, even if a phone number is provided.

If your evidence submission did not meet all of the necessary criteria, you will receive a Forensic Arson Laboratory Submission Criteria Sheet with your final lab report. Use this form as a checklist when sending evidence to ensure that your evidence will yield the best possible results.

The Forensic Arson Laboratory seeks to continually improve its procedures and services in order to provide the best possible forensic support for fire investigations. Any suggestions or comments are encouraged.  Please complete the Forensic Arson Laboratory Evaluation Form and email it to
