Industrial Hygiene Surveys and Compliance Audits
Toxic chemicals, particulates and other harmful emissions in the workplace can pose significant hazards to employees in today’s workforce.  Identifying these potential hazards through air monitoring and other environmental sampling techniques is a key step to ultimately determining the severity of potential exposures and implementing effective employee protection strategies.

EI’s staff of Certified Industrial Hygienists (CIH) and Certified Safety Professionals (CSP) can assist in managing chemical risks in your workplace. We use NIOSH/OSHA approved sampling methodologies to identify and assess these risks and develop appropriate engineering controls and personal protection plans.

EI professionals can assist in management of chemicals at your site through evaluation of programs such as Hazard Communication and Process Safety Management, conducting qualitative risk assessments and development of prioritized sampling plans and programs.

EI conducts employee exposure monitoring and industrial hygiene surveys. Sampling results are compared with established occupational exposure limits, including OSHA Permissible Exposure Limits (PELs), ACGIH Threshold Limit Values (TLVs) and other industry-established occupational exposure limits (OELs).

We provide best practice recommendations for engineering, PPE and administrative controls, and can provide support in their implementation and follow up evaluation.

All sample analysis is performed by American Industrial Hygiene Association (AIHA) accredited laboratories. The use of accredited labs establishes high standards of performance that promotes the production of quality data for use in evaluating exposures that impact public health, the environment and natural resources.

EI is dedicated to providing our clients with professional services according to the American Board of Industrial Hygiene (ABIH) Canons of Ethical Conduct.


These reports are simply the best laid out and easy to read reports I’ve ever received.  I could hand these to my operations teams without having to “translate” them.  These are very helpful.

MSHA Respirable Crystalline Silica Rule is Now in Place

MSHA Respirable Crystalline Silica Rule is Now in Place

On April 16, 2024, the Mine Safety and Health Administration (MSHA) implemented a new regulation concerning Respirable Crystalline Silica (RCS) (30 CFR Parts 56, 57, 60, 70, 71, 72, 75, and 90 Lowering Miners’ Exposure to Respirable Crystalline Silica and Improving Respiratory Protection), updating its Permissible Exposure Limit (PEL) and Action Level (AL) to match the standards set by OSHA in 2016.  In 2016, EI published a blog article addressing OSHA’s then-proposed rule on respirable crystalline silica (RCS), posing the question: “Will it See the Light of Day?” Interested readers are encouraged to revisit this post for a comprehensive discussion on the hazards associated with silica and an overview of the rule’s historical context.
