Your employees deserve a safe and healthy workplace.
Our industrial hygiene services focus on identifying and controlling risks that often go unseen, from chemical vapors in the air to excessive noise on the shop floor. By conducting occupational hygiene evaluations and exposure assessments, we help you spot problems before they turn into health issues or OSHA violations.
We’re here to help! Call us at (603) 228-3610 or fill out the form below.
What Is Industrial Hygiene?
Industrial hygiene (sometimes called occupational hygiene) is the science of keeping workers safe from workplace hazards across four main categories:
Chemical hazards & air contaminants (fumes, dusts, vapors)
Physical (noise, radiation, temperature, vibration)
Biological (bacteria, viruses, fungi)
Ergonomic (repetitive motion, heavy lifting)
Think of it as a check-up for your workplace environment. Just like a doctor runs tests to monitor your health, our specialists measure conditions in your workplace and recommend practical steps to keep your team safe.
Our Industrial Hygiene Services
Our team takes a practical, evidence-based approach to keep workplaces safe.
Indoor Air Quality & Airborne Contaminants
We help you understand what’s in the air your team breathes every day. From comfort complaints to serious health concerns, indoor air quality issues can affect productivity, morale, and long-term health. Services include:
- Indoor Air Quality (IAQ) assessments
- Mold evaluations and moisture investigations
- Radon testing
- Waste anesthetic gas monitoring (healthcare and clinical settings)
Whether it’s a musty smell, recurring symptoms, or regulatory concerns, we help identify the source(s) and provide practical solutions.
Chemical Exposure Monitoring
Chemical exposures aren’t always obvious — but they can have serious consequences over time. We conduct chemical exposure assessments to measure inhalation and skin contact risks and compare results to OSHA and industry guidelines. This includes:
- Air sampling for vapors, fumes, dusts, and mists
- Task-based exposure monitoring
- Evaluation of controls like ventilation and PPE
Our goal is to give you clear data and practical recommendations that actually work on the floor. Learn more about chemical exposure monitoring.
Noise Monitoring & Hearing Conservation
If your workplace gets loud, we’ll help you understand whether noise levels could be putting your team’s hearing at risk. We measure noise exposure, identify high-risk tasks, and support hearing conservation efforts. Services include:
- Noise level monitoring
- Employee exposure assessments
- Support for OSHA hearing conservation requirements
Asbestos & Lead Services
Older buildings and renovation projects can introduce serious health risks if asbestos or lead are present. Our team helps you identify, manage, and comply with regulations safely and responsibly. Services include:
- Asbestos inspections and management planning
- Lead exposure assessments and monitoring
- Support during renovations or maintenance activities
We focus on protecting workers while keeping projects moving safely.
Hazardous Materials Management
Managing hazardous materials goes beyond storage and labeling. We help you evaluate risks, improve handling practices, and meet regulatory requirements without overcomplicating the process. Support includes:
- Hazard identification and risk assessments
- Storage and handling evaluations
- Spill prevention and response planning
OSHA Compliance Support
Industrial hygiene plays a key role in meeting OSHA requirements. We help you understand what applies to your workplace, measure exposures accurately, and document findings properly. Our support includes:
- Exposure assessments aligned with OSHA standards
- Clear documentation and reporting
- Practical guidance to address identified issues
We make OSHA requirements understandable and achievable. Learn more about OSHA compliance services.
Why Industrial Hygiene Matters
Many workplace health risks aren’t obvious right away. Industrial hygiene helps you understand what your team is truly exposed to and make informed decisions that protect people and support your business.
Protects Employee Health
Identifies exposures that can lead to long-term health issues, helping keep your team safe, healthy, and able to do their jobs.
Reveals Hidden Risks
Measures things you can’t necessarily see or smell — like noise, chemical vapors, or airborne dust — so decisions are based on real data, not assumptions.
Prevents Costly Problems
Helps determine whether workplace exposures meet OSHA requirements and provides documentation to support compliance efforts.
Supports OSHA Compliance
Addresses issues early, reducing the risk of injuries, workers’ compensation claims, citations, and unexpected downtime.

Frequently Asked Questions About Industrial Hygiene
Industrial hygiene is the practice of identifying, measuring, and controlling workplace conditions that could affect employee health over time. According to OSHA, it focuses on anticipating, recognizing, evaluating, and controlling health hazards before they cause harm.
In practical terms, industrial hygiene typically addresses five main categories of workplace exposures:
- Airborne Contaminants: Particles and fibers such as dust, fumes, mists, or asbestos that remain suspended in the air and may be inhaled during normal work activities.
- Chemical Hazards: Gases, vapors, dusts, fumes, and mists that workers may breathe in, absorb through the skin, or accidentally ingest. This includes solvents, welding fumes, cleaning chemicals, and other substances used on the job.
- Physical Hazards: Environmental factors like excessive noise, heat, cold, vibration, radiation, or poor lighting that can cause injury or long-term health effects such as hearing loss or heat stress.
- Biological Hazards: Exposure to bacteria, viruses, mold, or other biological agents — common in healthcare, laboratories, schools, and facilities with moisture or ventilation issues.
- Ergonomic Hazards: Physical strain caused by repetitive motion, awkward postures, heavy lifting, or poorly designed workstations, which can lead to musculoskeletal injuries over time.
Industrial hygiene helps employers understand which of these risks are present, how significant they are, and what practical steps can be taken to keep employees safe and healthy.
Industrial hygiene is the traditional U.S. term while occupational hygiene is used more broadly internationally. They mean the same thing: focusing on protecting workers from hazards.
Hazards exist at workplaces of all sizes. Even small businesses can have risks like noise or dust exposure. Catching issues early saves costs, prevents injuries, and keeps your team safe.
Absolutely. OSHA sets limits on noise, chemical exposure, and many other workplace hazards. We help you measure and control risks so you stay compliant (and more importantly, keep your team safe).
