PHASE Associates understands the significance of protecting the health and safety of individuals in the workplace environment from potential airborne exposures, hazardous substances and noise. This is why industrial hygiene assessments are vital.
It is critical that employers follow industry, federal, state and local regulations. With supervision from an experienced Certified Industrial Hygienist (CIH), we will measure and evaluate worker exposures, physical stressors and chemical and biological contaminants. We can conduct assessments and surveys for industrial hygiene and occupational health and safety, including employee exposure monitoring, airborne sampling, risk assessments, noise surveys, indoor air quality, ergonomic concerns, and safety audits.
All industrial hygiene assessments are conducted in accordance with ACGIH, AIHA, ASHRAE, NIOSH and OSHA standards and guidelines. Our thorough knowledge of regulations as well as non-regulatory industrial hygiene standards of care will give you the confidence you need to make sound decisions about employee health risks.
Quantify and control employee exposure to a broad spectrum of airborne contaminants, including inorganic and organic analytes, metals, vapors, and gases. Our technical assessments utilize structured, scientific methodologies to evaluate acute and chronic health risks, ensuring your facility maintains strict adherence to established occupational exposure limits. We provide the high-fidelity data and analytical insights necessary to validate engineering and administrative controls and ensure regulatory compliance.
Execute personal and area sampling to capture quantitative exposure data in breathing zones and ambient work areas.
Perform comparative exposure assessments by benchmarking results against OSHA PELs, ACGIH TLVs, and NIOSH RELs for 8-hour TWA and 15-minute STEL limits.
Validate engineering controls to confirm local exhaust ventilation (LEV) effectiveness and identify potential breakthrough or overexposures.

An effective Hazard Communication program reduces risk, improves workplace safety, and ensures regulatory compliance.
Exposure to loud and sustain noise can have long term effects to hearing which can eventually lead to hearing loss. In response, OSHA and NIOSH have set legal limits on noise exposure in the workplace. These limits are based on a worker’s time weighted average over an 8-hour day.

An industrial hygiene assessment is a systematic evaluation of your workplace to identify, measure, and control health hazards that could affect your employees. Our CIH’s and IH’s conduct thorough walkthroughs, perform exposure monitoring, analyze data, and provide actionable recommendations to protect worker health and ensure OSHA compliance. This includes evaluating chemical exposures, physical hazards like noise, biological agents, and ergonomic risks.
You should consider an assessment if your employees work with chemicals, operate loud machinery, handle hazardous materials, or perform repetitive tasks. Warning signs include employee health complaints, visible dust or fumes, strong odors, high noise levels, or if you’re unsure about compliance with OSHA regulations. Even if you don’t have obvious concerns, periodic assessments help identify hidden hazards before they become problems.
Our comprehensive assessments typically include a facility walkthrough, employee and management interviews, review of safety data sheets and existing programs, air sampling for chemical exposures, noise level measurements, and evaluation of ventilation systems. We then provide a detailed report with findings, exposure data compared to OSHA limits, and prioritized recommendations for hazard control—from engineering solutions to administrative controls and PPE requirements.
The timeline varies based on your facility size, complexity, and the hazards being evaluated. A basic assessment for a small facility might take one day, while comprehensive evaluations of larger operations with multiple hazards could require several site visits over a few weeks. We’ll provide a clear timeline during our initial consultation and work efficiently to minimize disruption to your operations.
A health hazard evaluation is a comprehensive assessment that identifies potential hazards and determines if exposure monitoring is needed. Exposure monitoring involves collecting specific air samples or measurements to quantify employee exposures to particular contaminants and compare them against OSHA permissible exposure limits (PELs) or ACGIH threshold limit values (TLVs). Think of the evaluation as the diagnosis and monitoring as the testing that confirms it.
We provide both detailed exposure data and practical, prioritized recommendations. Our reports include clear explanations of findings, regulatory context, and a hierarchy of controls—from eliminating hazards at the source to engineering controls, administrative measures, and appropriate PPE. We don’t just identify problems; we partner with you to develop cost-effective solutions that fit your operations and budget.
We conduct comprehensive monitoring including air sampling for chemical vapors, gases, and particulates; noise dosimetry and area sound level surveys; welding fume analysis for heavy metals; respirable crystalline silica monitoring; heat stress assessments; and biological exposure assessments. Our laboratory partnerships are AIHA-accredited, ensuring accurate and defensible results.
Yes. Our assessments identify gaps in your compliance with OSHA standards and help you proactively address hazards before they result in citations, injuries, or illnesses. We evaluate your workplace against relevant OSHA regulations and provide documentation that demonstrates your commitment to worker safety—valuable during OSHA inspections or insurance audits.
