Watch the guide, collect your sample, then submit electronically via the Submit a CoC form or by PDF form. Standard PLM results in 24–48 hours.
Step-by-step video guide
Watch before you collect. Covers safe sampling technique, double-bagging, labeling, and how to complete the chain-of-custody form.
Two ways to submit
Submit electronically via the Submit a CoC form for fastest processing, or download a PDF chain-of-custody form to include with a drop-off or shipment.
Electronic Submittal
Fill out your chain-of-custody online before you arrive. Fastest intake — no paper, no queue at the counter.
- 1 Go to the Submit a CoC form and complete the online chain-of-custody form.
- 2 Note the sample IDs generated — write them on your sample bags before you collect.
- 3 Collect your samples following the guide below and drop off or ship to our lab.
- 4 Results emailed as a PDF with the signed chain-of-custody attached.
PDF Form Submittal
Download, print, and complete the asbestos chain-of-custody form. Include it with your samples at drop-off or inside the shipping package.
- 1 Download the Asbestos CoC form from the Forms page and print it.
- 2 Fill in all fields: your contact info, each sample ID & location, analysis requested, and turnaround needed.
- 3 Collect samples following the guide below, bag & label each one.
- 4 Drop off at 2333 US-22 West, Union, NJ before 4 PM, or ship overnight with the form inside the package.
Collecting and packaging the sample
Follow these steps so your sample arrives safely and your result is defensible. If the material is friable or heavily contaminated, have a licensed professional collect it instead.
Prepare the area and collect a representative piece
Shut down any heating or cooling system so released fibers don’t spread, and disturb the material as little as possible. Lightly mist it with water containing a few drops of dish detergent, then use a clean, sharp tool to cut through the full depth so every layer is captured. Take a small amount of each distinct material — about a teaspoon of friable material, or a one-inch square of non-friable material — and keep each material in its own bag. Do not mix different materials.
Double-bag and seal
Place each sample in its own zip-seal bag, then seal that inside a second bag. Wipe down the outside of both bags with a damp cloth. One material per double-bag.
Label each bag
Mark each bag with the sample ID and the location it came from (e.g. “S1 — basement pipe wrap”). The label must match exactly what is on your chain-of-custody form.
Complete the chain-of-custody
List every sample ID, the material type, sample location, and the analysis needed (PLM, point count, or TEM). Note your required turnaround. Sign and date the form.
Drop off or ship
Drop off at 2333 US-22 West, Union, NJ 07083, Monday–Friday before 4 PM ET. Or ship overnight — include the CoC inside the package. Need a prepaid label? Get a shipping label →
Receive your results
Standard PLM turnaround is 24–48 hours. Rush and same-day options are available. Results are emailed as a PDF with the signed chain-of-custody attached.
Special sampling situations
Some materials need extra care or a set number of samples. Check these before you collect.
Large areas (over 1,000 sq ft)
Take samples from several representative locations rather than a single spot, so the result reflects the whole area.
Mastic & adhesives
Submit any mastic or adhesive as a separate sample from the material bonded above it — the two layers are analyzed independently.
Vermiculite insulation
Collect about three cup-sized samples from different areas. Vermiculite needs a larger volume for reliable analysis.
NOB materials & TEM confirmation
For non-friable organically bound materials — floor tile, mastic, roofing, and caulk — a “none detected” PLM result should be confirmed by TEM, the method EPA recognizes as reliable for these matrices.
