Industrial Hygiene Testing by Industry — Hazards, Methods & Exposure Limits by Sector
The hazard list changes with the work. A refinery turnaround is dominated by benzene and hydrogen sulfide; a fabrication shop by manganese welding fume and hexavalent chromium; an upstream site by respirable silica off frac sand. Each program below maps its sector’s hazards to the accredited method that measures them, with the OSHA limits and sample types laid out. Samples are collected by your team or your consultant and analyzed in-house at our Houston lab, for sites anywhere in the United States.

Each page links down to the accredited analyte methods behind it — benzene, H₂S, silica, welding fume, hexavalent chromium, asbestos and more.
Same plants, two different services — pick by timeline. A scheduled shutdown runs on turnaround rules; day-to-day operation runs on routine compliance.
Turnaround & Shutdown Air Monitoring
For scheduled outages only — high-volume, compressed-timeline exposure monitoring at scale: reserved lab capacity, 1-day rush and a dedicated PM for the outage window.
View turnaround program →Routine Refinery & Plant Compliance
For day-to-day operating plants, not shutdowns — ongoing compliance and similar-exposure-group monitoring: benzene, H₂S, welding fume, silica.

The 18 programs above are the sectors we've written up in depth — they aren't the only industries we serve. We also support general manufacturing, aerospace and defense, and pharmaceutical production. What actually matters is the analyte: if your operation generates silica, metals, solvents, mold, Legionella, asbestos or any other hazard on our services list, we analyze it under the same accreditation, from sites anywhere in the U.S.
How Our Industrial Hygiene Programs Work
Every industry we serve has a distinct industrial hygiene exposure profile. A refinery turnaround is dominated by benzene and hydrogen sulfide; a fabrication shop by manganese welding fume and hexavalent chromium; an upstream oilfield by respirable silica from frac sand. Each industry page maps that sector's hazards to the accredited method that measures them — so you can go straight to what applies to your operation, with the OSHA exposure limits and sample types laid out.
Behind every industrial hygiene program is the same lab. AGT Labs is an analytical laboratory — your team or your consultant collects the samples, and every analysis is performed in-house at our Houston facility under AIHA-LAP accreditation, with no subcontracting and one chain of custody from your site to the report. Because it all happens in one place, your location changes nothing about the result: we ship pre-labeled sampling kits and calibrated loaner pumps to sites anywhere in the United States under our nationwide ship-in program, log samples in the same day when they arrive before 2:00 PM CST, and offer rush turnaround down to one business day. Scheduled courier pickup runs across the Texas Gulf Coast for local clients. Recurring work runs on a standing account with reserved capacity and consistent reporting.
Accredited & in-house
AIHA-LAP analysis under one roof, with NVLAP and PJLA on asbestos — no send-outs, one chain of custody.
1-day rush
Same-day log-in before 2 PM CST; rush turnaround to 1 business day.
Kits & pumps
Pre-labeled media shipped to any U.S. site; loaner pumps for qualifying accounts. Your team collects — we analyze.
Standing accounts
Reserved capacity and consistent reporting for recurring monitoring.
Which industrial hygiene program fits my site?
Pick the sector closest to your operations — each page lists the hazards, methods and exposure limits for that industry. Note that scheduled shutdowns have a dedicated turnaround air monitoring program separate from routine refinery IH testing. If you're unsure, call (713) 453-6090 and a lab manager will scope the right sampling plan.
My industry isn't listed — can you still help?
Yes. The 18 programs above are the sectors we have written up in detail, not the limit of who we serve. We also support general manufacturing, aerospace and defense, and pharmaceutical production, among others. The analytes are what matter: if your operation generates silica, metals, solvents, mold, Legionella, asbestos or any of the other hazards on our services list, we can analyze it under the same accreditation. Call (713) 453-6090 and a lab manager will scope a sampling plan for your industry.
Do you serve sites outside Texas and the Gulf Coast?
Yes — anywhere in the United States. Every sample is analyzed at the same Houston lab, so your location changes nothing about the methods, the accreditation or the rush options. We ship a kit scoped to your hazards with a prepaid return label, and samples received before 2:00 PM CST are logged the same day; overnight delivery puts a distant site on the same rush schedule as a local one. The OSHA standards we report against are federal and apply in every state, and our AIHA-LAP, NVLAP and PJLA accreditations are recognized nationwide. Scheduled courier pickup runs across the Texas Gulf Coast for local clients.
Do you analyze samples in-house or send them out?
Every analyte is run in-house at our Houston lab under AIHA-LAP accreditation, covering both the industrial hygiene and environmental microbiology programs — no subcontracting. For asbestos specifically, bulk PLM is NVLAP-accredited under Lab Code 101793-0 and PJLA Accreditation No. 137751 covers both PLM and PCM to ISO/IEC 17025:2017. That means one chain of custody, consistent methods across your whole program, and faster turnaround.
How fast is turnaround?
Standard turnaround runs from 5+ business days down to 1-day rush on most analytes. Turnaround is counted from log-in at the lab, and samples received before 2:00 PM CST are logged the same day. Shutdown and outage programs are set up on a standing account with reserved capacity so a compressed schedule never waits on results.
Do you supply sampling kits and pumps?
Yes. We ship pre-labeled sampling kits and sorbent media to sites anywhere in the U.S., and offer a calibrated pump loaner program for qualifying accounts, so your team can sample on schedule and ship media back for same-day log-in.
Not sure which program fits?
Tell us your site, hazards and timeline and a lab manager will scope the right sampling plan and turnaround — wherever you operate.
