Industrial Hygiene Testing
Comprehensive industrial hygiene testing and laboratory analysis ensuring safety through rigorous workplace exposure monitoring.
View Services Our accredited industrial hygiene testing services based in Houston, TX AGT Labs, deliver trusted solutions to protect worker health and ensure full OSHA, NIOSH, and EPA compliance. We specialize in IH testing for Asbestos, Silica (RCS), Lead, Metals, Dust, Mold & Bioaerosols, VOCs, IAQ, Noise, and Heat Stress.
Our Industrial Hygiene Testing Services
Asbestos Testing
We provide comprehensive testing for both Friable and Non-Friable Asbestos Materials and airborne fibers, ensuring strict compliance with OSHA (29 CFR 1910.1001 / 1926.1101) and EPA regulations. IH testing for asbestos clearance include bulk sampling using Polarized Light Microscopy (PLM) and advanced air monitoring via Phase Contrast Microscopy (PCM) for clearance and Transmission Electron Microscopy (TEM) for definitive identification.

BTEX / VOCs / TO-15 & TO-17
For organic vapor analysis, particularly within petrochemical and manufacturing environments, we utilize specialized industrial hygiene testing services for indoor air quality, including charcoal tubes, passive badges, and Tedlar bags/Canisters. This service targets BTEX (Benzene, Toluene, Ethylbenzene, Xylene), monitors Total Volatile Organic Compounds (TVOC), and analyzes specific air pollutants using EPA Method TO-15.

Dust, Total & Respirable
We perform monitoring for general workplace particulates, classified as Particulates Not Otherwise Regulated (PNOR). Our service involves Gravimetric Analysis via air sampling to accurately measure both the total mass of dust and the smaller, more hazardous Respirable Dust fraction that can penetrate deep into the lungs, ensuring compliance with general industry OSHA PELs.

Indoor Air Quality (IAQ)
Comprehensive IAQ surveys combining real-time sensors and laboratory analyses to measure CO₂, PM₂.₅/PM₁₀, TVOCs, formaldehyde, temperature, and humidity. Ideal for offices, schools, and healthcare facilities our industrial hygiene testing services for indoor air quality help diagnose complaints, verify ventilation, and optimize occupant health.

Inorganic Chemicals / Reactive Gases Testing
We provide real-time and time-weighted average monitoring for highly hazardous inorganic gases and vapors, including Hydrogen Sulfide (H2S), Carbon Monoxide (CO), Ammonia (NH3), Ozone (O3), and Chlorine Gas (Cl2). We utilize both Direct Read Instrumentation and Impinger/Treated Filters for laboratory-based compliance analysis providing reliable Industrial Hygiene testing for toxic gas exposure against OSHA PELs.

Lead Testing ( Air, Paint, & Surfaces )
Our lead services address industrial and construction hazards, including monitoring for Airborne Lead dust and assessing bulk materials. We use X-Ray Fluorescence (XRF) for rapid Lead in Paint surveys and perform lead wipe testing for clearance following abatement, ensuring adherence to the stringent OSHA Lead Standard through professional IH assessments.(29 CFR 1910.1025) and EPA RRP rules.

Metals and Hexavalent Chromium (Cr VI)
Beyond general welding fumes, we specialize in assessing exposure to highly toxic metal compounds. This includes industrial hygiene testing for Hexavalent Chromium (CrVI) monitoring for trace metals like Beryllium and conducting specific sampling and analysis for Hexavalent Chromium (CrVI), using dedicated methods (like OSHA Method ID-215) to comply with the specific OSHA CrVI Standard (29 CFR 1910.1026).

Metals in Air & Welding Fume Testing
To protect welders from the complex mixture of airborne contaminants, we conduct targeted air monitoring for Welding Fumes Metals such as Iron, Manganese, Nickel, and Cadmium. Samples collected on Mixed-Cellulose Ester (MCE) filters are analyzed using techniques like ICP or AA spectrometry, with all work calibrated to OSHA PELs for individual fume components.

Mold & Bioaerosols
Our experts conduct detailed Indoor Air Quality (IAQ) Investigations to identify sources of moisture intrusion, assess building systems, and evaluate exposure to biological contaminants like Aspergillus, Penicillium, and Stachybotrys. We employ various Air and Surface Sampling techniques, including spore traps, tape lifts, and swabs, to adhere to state regulations.

Noise & Heat Stress Screening
Preliminary noise dosimetry and WBGT heat stress screenings to identify high-risk tasks and zones. We provide rapid field surveys, exposure mapping, and recommendations for hearing conservation, administrative controls, and heat stress mitigation strategies.

Respirable Crystalline Silica (RCS)
To meet the stringent OSHA Respirable Crystalline Silica Standard, we offer specialized exposure monitoring for crystalline forms like Alpha Quartz, Cristobalite, and Tridymite. Our process involves personal air sampling using cyclones and filter media, which is then analyzed using sophisticated methods like X-Ray Diffraction (XRD), typically following NIOSH 7500/OSHA ID-142 procedures.

Solvents, Acids, and Alkali
We assess employee exposure to a wide array of reactive and corrosive agents such as Acetone, Isocyanates, Formic Acid, and Sodium Hydroxide. Monitoring is achieved through Chemical-Specific Sampling, employing specialized collection media like sorbent tubes, impingers, or passive badges, with analysis tailored to meet specific OSHA PELs providing customized industrial hygiene testing services for solvents and acids.
