Comprehensive exposure assessment and environmental monitoring services designed for the unique hazards of data center operations—from battery room off-gassing to diesel generator exhaust.
Mission-critical facilities present industrial hygiene challenges distinct from traditional office or industrial environments. The combination of high-density electrical infrastructure, backup power systems, and precision cooling creates exposure pathways that require specialized assessment methodologies.
Our industrial hygienists bring deep expertise in evaluating data center-specific hazards including battery room hydrogen evolution, diesel particulate matter from emergency generators, refrigerant system exposures, and noise from high-velocity cooling systems.
Full-spectrum exposure assessment and environmental monitoring aligned with AIHA best practices and OSHA compliance requirements.
Comprehensive IAQ assessment including particulate matter (PM2.5/PM10), VOCs, carbon dioxide, carbon monoxide, and humidity. Direct-reading instrumentation and laboratory analysis for characterization of contamination sources in white space and support areas.
Dosimetry studies and area sound level surveys to evaluate compliance with OSHA permissible exposure limits (90 dBA TWA, 5 dB exchange rate). Assessment of hearing conservation program requirements and engineering control feasibility.
Personal and area sampling for chemical hazards including diesel particulate matter, battery room gases (hydrogen, sulfuric acid), refrigerants, and cleaning/maintenance chemicals. Comparison to ACGIH TLVs and OSHA PELs with statistical analysis.
Quantitative evaluation of general and local exhaust ventilation systems using tracer gas studies, capture velocity measurements, and pressure differential mapping. Battery room ventilation rate calculations per NFPA 70E and IEEE standards.
ASHRAE-compliant thermal environment assessment including dry bulb temperature, radiant temperature, relative humidity, and air velocity. Evaluation of hot aisle/cold aisle strategies and identification of thermal stress risk areas.
Pre-demolition and pre-renovation surveys for asbestos, lead-based paint, PCBs in legacy electrical equipment, and mercury in older UPS systems. Chain-of-custody sampling and NVLAP-accredited laboratory analysis.
Mission-critical facilities present unique exposure pathways that require specialized assessment protocols and control strategies.
VRLA & Lithium-Ion Systems: Hydrogen evolution during charging cycles presents explosion risk (4% LEL) and requires continuous ventilation. Sulfuric acid mist from flooded lead-acid batteries creates respiratory hazard (ACGIH TLV: 0.2 mg/m³ thoracic fraction).
Assessment Protocol: Real-time hydrogen monitoring with electrochemical sensors, acid mist sampling using mixed cellulose ester filters, ventilation rate verification, and worst-case scenario modeling during equalize charging.
Generator Testing Operations: Monthly and annual load bank testing creates diesel particulate matter (DPM) and nitrogen dioxide exposures. NIOSH REL for DPM: 0.05 mg/m³ elemental carbon; OSHA PEL for NO₂: 5 ppm ceiling.
Assessment Protocol: Personal sampling for DPM using NIOSH Method 5040, direct-reading NO₂ monitoring during testing procedures, evaluation of exhaust routing and dilution ventilation adequacy, administrative control review.
Raised Floor Environments: Underfloor supply air plenums can accumulate and distribute particulate contamination from outside air intake, construction activities, or equipment off-gassing. ISO Class 8 (100,000 particles/ft³ ≥0.5 µm) typically adequate for IT equipment protection.
Assessment Protocol: Optical particle counting at server inlet locations, filter efficiency testing, differential pressure monitoring across air handling units, source identification through microscopy and chemical analysis.
HVAC & Fire Suppression Systems: Acute exposure risk during refrigerant leaks or fire suppression discharge events. Common refrigerants (R-134a, R-410A) have AIHA WEELs of 1,000 ppm; clean agents (FM-200, Novec 1230) have NOAEL values requiring oxygen displacement consideration.
Assessment Protocol: Leak detection surveys using infrared cameras and electronic sensors, worst-case discharge modeling for occupied spaces, oxygen deficiency risk assessment, emergency ventilation verification, respiratory protection program evaluation.
