Shipyard, Marine & LNG Construction Industrial Hygiene Testing
Worker exposure monitoring for shipyards, marine fabrication and LNG construction — welding fume, hexavalent chromium, blasting silica and lead analyzed in-house at our Houston lab, with 1-day rush and kits shipped straight to the yard.
Why Shipyards & Marine Contractors Use AGT
Accredited & Defensible
AIHA-LAP analysis with NVLAP for asbestos — data that holds up with OSHA maritime enforcement, prime contractors and insurers.
Hex Chrome & Lead Ready
The two exposures that define blasting and stainless welding — analyzed in-house by OSHA ID-215 and NIOSH 7300/7082.
Kits to the Yard
Pre-labeled media and calibrated loaner pumps ship to the yard for confined-space and hot-work sampling.
1-Day Rush
Same-day log-in before 2 PM CST and rush to 1 business day keeps blasting and coating fronts moving.
Exposure Monitoring for Steel, Coatings & Confined Spaces
Shipbuilding, ship repair, marine fabrication and LNG construction concentrate some of the highest-exposure work in industry: heavy welding and cutting on carbon and stainless steel, abrasive blasting of coated hulls and structures, and spray application of marine coatings — much of it inside tanks, holds and other confined spaces. AGT Labs is the accredited industrial hygiene lab behind that monitoring, analyzing every sample in-house in Houston.
We support Gulf Coast yards and LNG fabrication sites by shipping kits to the yard and receiving media by courier. Steel and coatings work overlaps closely with our welding fume and hexavalent chromium analyses.
- Welding fume and metals by ICP-AES for carbon and stainless work
- Hexavalent chromium by OSHA ID-215 — stainless welding and blasting
- Abrasive-blasting respirable silica by X-ray diffraction
- Lead by NIOSH 7300 / 7082 from coated-steel blasting
- Isocyanates from marine and epoxy coatings; asbestos from legacy materials
- Noise and heat stress in confined and hot-work spaces
The Exposures That Define Marine & Shipyard Work
Steel, coatings and confined spaces create a distinct hazard mix. These are the exposures our shipyard monitoring is built around.
Welding Fume & Hex Chrome
Heavy welding and cutting on carbon and stainless steel — metals by ICP-AES, hexavalent chromium by OSHA ID-215.
Blasting Silica & Lead
Abrasive blasting of coated hulls releases respirable silica (XRD) and lead (NIOSH 7300/7082) together.
Coatings & Asbestos
Isocyanates from marine and epoxy coatings, plus asbestos (PLM/PCM) from legacy vessel materials.

Exposure Monitoring by Yard Operation
The dominant hazard shifts with the trade. We match the sampling plan to the work front.
| Operation | Dominant Activity | Priority Analytes | Lab Method |
|---|---|---|---|
| Welding & cutting | Carbon & stainless steel, confined spaces | Welding fume, hex chrome, metals | ICP-AES · OSHA ID-215 |
| Abrasive blasting | Hull & structure surface prep | Respirable silica, lead | XRD · NIOSH 7300 / 7082 |
| Coating & painting | Marine & epoxy spray coatings | Isocyanates, solvents | Isocyanate · NIOSH 1500-series |
| Repair & retrofit | Legacy vessel materials | Asbestos, lead | PLM/PCM · NIOSH 7300 |
| General yard | High-noise, outdoor, hot work | Noise, heat stress | Dosimetry · WBGT |
Shipyard Analytes & OSHA Exposure Limits
The regulated limits your monitoring program is measured against, and the method our lab runs for each.
| Hazard | OSHA PEL (8-hr TWA) | Lab Method | Sample Type |
|---|---|---|---|
| Hexavalent chromium | 5 µg/m³ | OSHA ID-215 | PVC filter, personal |
| Lead | 50 µg/m³ (AL 30 µg/m³) | NIOSH 7300 / 7082 | MCE 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 |
| Noise | 90 dBA (AL 85 dBA) | Dosimetry | Personal dosimeter |
