Louisiana Industrial Hygiene Testing — Gulf Coast Refinery Corridor
Accredited IH analysis for Louisiana's refinery & petrochemical corridor — Baton Rouge, Lake Charles, New Orleans and the Geismar-Gonzales plant belt. Benzene, H₂S, silica & welding fume analyzed in-house, next door in Houston. Samples in before 2:00 PM CST logged same day.
Why Louisiana Plants Send Samples to AGT
Accredited Lab, Not a Middleman
The firms ranking for "industrial hygiene Baton Rouge" are mostly consultants who ship samples out. We're the accredited lab — you skip the handoff.
Next-Door Turnaround
Houston sits a short courier hop from the corridor. Samples in before 2 PM CST log same day; rush down to 1 business day.
Refinery-Fluent
Benzene, H₂S, hex chrome, welding fume and silica are our daily work — the exact panel a Gulf Coast plant or turnaround runs.
Kits & Pumps Shipped In
Pre-labeled media and a calibrated pump loaner program reach your site so crews sample on schedule.
Refinery & Petrochemical IH Analysis, Handled In-House
From Baton Rouge to New Orleans, Lake Charles to the Geismar-Gonzales plant belt, Louisiana's refineries and chemical plants run some of the most exposure-intensive work in the country — under active regulatory pressure on benzene and fenceline monitoring. AGT Labs is the accredited industrial hygiene lab behind that work, with every sample analyzed in our Houston facility, no subcontracting, one chain of custody.
The consultants who rank locally for corridor IH work ship their samples out of state to a lab like ours. Working with us directly removes the middleman and shortens the clock — which matters most when a turnaround or unit is waiting on results.
- Personal and area benzene / BTEX by NIOSH 1501 / OSHA 1028
- H₂S and acid gases by ion chromatography
- Welding fume, metals and hexavalent chromium for fabrication & maintenance
- Respirable crystalline silica by X-ray diffraction
- Asbestos (NVLAP) and mold (AIHA-EMLAP) for legacy plant materials & facilities
- Standing-account turnaround programs with reserved capacity
Louisiana Industries We Support
Louisiana's industrial base is concentrated, high-hazard and heavily regulated — exactly where accredited exposure data matters most.
Refineries & Petrochemical
The Baton Rouge-New Orleans corridor and Lake Charles complex — benzene/BTEX, H₂S, PAH, catalyst metals, and turnaround exposure monitoring.
Chemical Manufacturing
The Geismar-Gonzales "plant belt" — VOCs, butadiene, formaldehyde, isocyanates, acids/alkali, and airborne metals.
LNG & Marine Construction
Gulf LNG terminals and shipyards — welding fume and hexavalent chromium, abrasive-blasting silica, lead, and asbestos.
Industrial & Specialty Contractors
Turnaround, maintenance and abatement crews needing fast, defensible personal and area exposure results.
Facilities & Government
IAQ and mold assessments for public buildings, ports and commercial facilities across the state.
Turnaround Programs
Standing accounts with reserved capacity, priority handling and a dedicated PM for shutdown events.
What We Analyze for Louisiana Sites
Every analyte below is run in-house under accreditation. Tap any card for the full method detail on our service pages.
Benzene & BTEX
NIOSH 1501 / OSHA 1028 — the defining refinery and petrochemical exposure.
View Service →H₂S & Reactive Gases
Ion chromatography for hydrogen sulfide and acid gases across sour-service units.
View Service →Welding Fume & Metals
ICP-AES for 30+ elements — fabrication, maintenance and turnaround welding.
View Service →Noise & Heat Stress
Dosimetry and WBGT — critical for Louisiana's heat and high-noise units.
View Service →Corridor Analytes & OSHA Exposure Limits
The regulated limits your sampling program is measured against, and the method our lab runs for each. Our accreditations are national — not tied to Texas — and apply fully to Louisiana work.
| Hazard | OSHA PEL (8-hr TWA) | Lab Method | Sample Type |
|---|---|---|---|
| Benzene | 1 ppm (STEL 5 ppm) | NIOSH 1501 / OSHA 1028 | Charcoal tube, personal |
| Hydrogen sulfide (H₂S) | 20 ppm ceiling (ACGIH TLV 1 ppm) | Ion chromatography | Treated filter / bubbler |
| Hexavalent chromium | 5 µg/m³ | OSHA ID-215 | PVC filter, personal |
| Respirable crystalline silica | 50 µg/m³ | XRD (NIOSH 7500 / OSHA ID-142) | Cyclone + PVC filter |
| Welding fume metals (e.g. Mn) | Mn 5 mg/m³ (ACGIH 0.02 resp.) | ICP-AES | MCE filter, personal |
| Asbestos | 0.1 f/cc | PCM (NIOSH 7400) / PLM | MCE filter / bulk |

Accredited Analysis, Next Door to Louisiana
AGT Labs analyzes every Louisiana sample at 10200 East Freeway, Suite 101, Houston TX 77029, with same-day log-in for samples received before 2:00 PM CST. Louisiana's asbestos accreditation program licenses field inspectors, not the analyzing lab — our NVLAP and AIHA-LAP accreditations cover the analysis.
