Built for Lake Charles Construction Scale
Surge Capacity
Standing accounts and reserved lab capacity absorb the sample volume a large LNG or petrochemical build generates.
Accredited & Defensible
AIHA-LAP, NVLAP and PJLA — results that hold up with OSHA, EPC contractors and insurers.
Overnight Courier
Southwest Louisiana is a short courier hop from Houston — media collected today reaches the lab overnight.
1-Day Rush
Rush to 1 business day and same-day log-in for arrivals before 2 PM CST keeps a compressed schedule moving.

Exposure Monitoring for Southwest Louisiana's Build-Out
Lake Charles anchors one of the largest concentrations of LNG export terminals and petrochemical expansion projects on the Gulf Coast, alongside long-standing refining and chemical manufacturing along the Calcasieu Ship Channel. That mix of new construction and brownfield turnaround work drives sustained demand for welding fume, silica, benzene and H₂S monitoring, often at a scale that spans hundreds of craft workers on a single project.
AGT Labs supports Lake Charles-area EPC contractors, industrial employers and safety consultants with accredited, in-house analysis at our Houston laboratory — no send-outs, one chain of custody, and standing-account capacity sized to a project's schedule. See our construction, metal fabrication & welding and petrochemical turnaround programs for sector-specific detail.
- Welding fume, manganese and hexavalent chromium — ICP-AES / OSHA ID-215
- Respirable crystalline silica by XRD — concrete, refractory, blasting
- Benzene / BTEX and H₂S — NIOSH 1501 / OSHA 1028, ion chromatography
- Asbestos (NVLAP bulk PLM; PJLA PLM/PCM) for brownfield expansion work
- Standing accounts sized to project workforce and schedule
Who does what: AGT Labs is an analytical laboratory — the EPC contractor’s safety team or your IH consultant collects the samples on site. We scope and ship the kits, the courier moves sealed media overnight, and we analyse. We do not run site surveys or field sampling.
