Industrial Hygiene Assessments

Unlike visible safety hazards — unguarded machines, fall risks, chemical spills — industrial hygiene hazards are often invisible. Airborne contaminants, noise levels, heat stress, and ergonomic risk factors silently erode worker health over months and years. By the time symptoms appear, the damage may be irreversible. Industrial hygiene is the science of anticipating, recognizing, evaluating, and controlling workplace environmental factors that may cause sickness, impaired health, or significant discomfort among workers. Our industrial hygiene assessments go beyond compliance checklists — we conduct quantitative exposure monitoring that gives you defensible data on exactly what your workers are exposed to and whether your controls are adequate.

We conduct personal and area air monitoring for the full range of workplace airborne contaminants: • Respirable Dust and Crystalline Silica: Critical for construction, foundries, concrete cutting, and sandblasting operations. OSHA's silica standard (1910.1053 / 1926.1153) requires exposure assessment and medical surveillance. • Chemical Vapors and Gases: Solvent exposure, acid mists, welding fumes, isocyanates, formaldehyde, and other regulated substances. We compare results against OSHA PELs, ACGIH TLVs, and NIOSH RELs. • Heavy Metals: Lead, cadmium, chromium, manganese, and other metals in manufacturing, construction, and battery recycling operations. • Asbestos and Lead-Based Paint: Building surveys, bulk sampling, and air monitoring during renovation and demolition activities. All sampling is conducted using NIOSH-validated analytical methods with results reported by AIHA-accredited laboratories.

Noise-induced hearing loss is the most common occupational disease in the United States — and it is 100% preventable. OSHA's noise standard (1910.95) requires employers to implement a hearing conservation program when employee noise exposures equal or exceed an 8-hour time-weighted average of 85 dBA. Our noise assessments include: • Personal noise dosimetry (full-shift TWA measurements) • Area sound level mapping (noise contour maps) • Engineering control evaluation (machine isolation, barriers, damping) • Hearing conservation program review • HPD (hearing protection device) adequacy assessment using OSHA's derating methods We identify not just whether you have a noise problem, but exactly where it comes from and what engineering and administrative controls can reduce exposure below action levels.

Musculoskeletal disorders (MSDs) are the leading cause of workplace disability in the United States, accounting for roughly one-third of all workers' compensation costs. Our ergonomic assessments use recognized methodologies including RULA, REBA, NIOSH Lifting Equation, and Strain Index to quantify risk for: • Manual material handling tasks • Repetitive motion operations • Awkward posture exposures • Vibration exposure (hand-arm and whole-body) • Heat stress in outdoor and industrial environments We provide prioritized recommendations with estimated risk reduction — giving you the data to make evidence-based decisions about ergonomic interventions.

Industrial hygiene data is only valuable if it is credible. When exposure monitoring is conducted by the same organization responsible for production output, there is an inherent conflict of interest — even if unintentional. Independent, third-party industrial hygiene assessments provide data that will withstand regulatory scrutiny, litigation discovery, and workers' compensation challenges. Our assessments follow recognized professional standards (AIHA, ACGIH, NIOSH) and produce reports that serve as defensible documentation of your commitment to worker health protection.
