Workers in construction, manufacturing, energy, and industrial operations face airborne hazards ranging from silica dust and welding fumes to chemical vapors, biological agents, and respirable particulates. MAC Safety's air quality assessments quantify these exposures through personal and area sampling, identify contamination sources, and evaluate the effectiveness of existing ventilation and control measures.
MAC's industrial hygiene professionals conduct sampling programs using NIOSH-validated methods, analyze results against OSHA permissible exposure limits (PELs), ACGIH threshold limit values (TLVs), and project-specific requirements. Assessment reports document exposure levels for each worker, task, and location — providing the data needed for exposure control planning, respiratory protection program administration, and medical surveillance determinations.
Air quality assessment data flows into the NIXN platform, creating a longitudinal record of workplace exposures that tracks conditions over time. NIXN correlates exposure data with work activities, ventilation configurations, and seasonal conditions — identifying the operational factors that drive exposure variability and enabling targeted controls that address root causes rather than symptoms.
