Key Responsibilities and Required Skills for an Industrial Hygienist

🎯 Role Definition

An Industrial Hygienist is a dedicated scientist and strategist for workplace health. This role is fundamentally about protecting an organization's most valuable asset—its people. By applying scientific principles, the Industrial Hygienist anticipates, recognizes, evaluates, and controls environmental factors and stressors in the workplace that could lead to injury, illness, or impairment. They are the proactive guardians of occupational health, blending fieldwork, data analysis, and human interaction to create a safer and healthier work environment. This position is critical not only for regulatory compliance but for fostering a culture of care, minimizing risk, and ensuring long-term operational sustainability.

Core Responsibilities

Primary Functions

Develop, implement, and manage comprehensive industrial hygiene programs and policies to ensure full compliance with federal, state, and local regulations (e.g., OSHA, EPA).
Conduct detailed qualitative and quantitative exposure assessments for chemical, physical, and biological agents, including airborne contaminants, noise, radiation, and thermal stress.
Perform scientific monitoring and sampling of potential workplace hazards using a wide range of industrial hygiene instrumentation and media, ensuring proper calibration and maintenance of all equipment.
Interpret complex sampling data, compare results against Occupational Exposure Limits (OELs) like OSHA PELs and ACGIH TLVs, and prepare detailed technical reports with actionable findings and recommendations.
Develop and implement effective hazard control strategies using the hierarchy of controls, with a focus on engineering controls (e.g., ventilation) and administrative controls before relying on personal protective equipment.
Lead the selection, implementation, and management of the company's Personal Protective Equipment (PPE) program, including hazard assessments, selection, fit-testing, and employee training.
Manage and serve as the technical expert for specific health and safety programs such as Hearing Conservation, Respiratory Protection, Hazard Communication, and Chemical Hygiene.
Conduct ergonomic assessments of workstations, tools, and manufacturing processes to identify risks for musculoskeletal disorders and recommend practical solutions for risk reduction.
Provide expert technical guidance and support to management, engineering, and operational teams on all matters related to industrial hygiene and occupational health.
Develop and deliver engaging and effective industrial hygiene training for employees at all levels, covering topics like chemical safety, hazard recognition, and proper PPE use.
Serve as a primary point of contact and subject matter expert during regulatory inspections from agencies like OSHA, providing documentation and demonstrating program effectiveness.
Investigate employee health concerns and potential occupational illnesses, conducting thorough root cause analyses to implement robust corrective and preventive actions.
Maintain meticulous and audit-ready records of all exposure monitoring data, training sessions, medical surveillance programs, and equipment calibrations in an organized database.
Evaluate the introduction of new chemicals, materials, and processes by conducting a thorough risk assessment to identify and mitigate potential health hazards before implementation.
Review and approve Safety Data Sheets (SDS) and manage the facility's chemical inventory and Hazard Communication program to ensure accuracy and compliance.
Oversee the facility's industrial ventilation systems, conducting periodic evaluations to ensure they are designed and operating effectively to control airborne contaminants.
Manage relationships with third-party consultants and analytical laboratories, ensuring high quality of service, proper accreditation, and timely delivery of results.
Prepare and manage the industrial hygiene program budget, including forecasting needs for new equipment, sampling media, lab analysis, and external services.
Participate in and/or lead incident investigation teams, focusing on the occupational health aspects of incidents and near misses to prevent recurrence.
Author, review, and update corporate and site-specific industrial hygiene standards, procedures, and guidance documents to reflect best practices and regulatory changes.
Conduct comprehensive audits of industrial hygiene programs at various company sites to ensure consistent implementation and identify opportunities for continuous improvement.

Secondary Functions

Actively participate in site-level safety committees, providing expert input on health-related topics and exposure control strategies.
Collaborate with occupational health nurses and physicians on the design and implementation of medical surveillance programs based on exposure risks.
Assist in the development and execution of emergency response plans, particularly for scenarios involving chemical releases or other hazardous material exposures.
Support environmental compliance initiatives where there is an overlap with occupational health, such as air permitting or hazardous waste management.

Required Skills & Competencies

Hard Skills (Technical)

Proficiency in operating and calibrating a wide range of industrial hygiene monitoring equipment (e.g., noise dosimeters, air sampling pumps, direct-read instruments).
Deep knowledge of federal, state, and local health and safety regulations (OSHA, MSHA, EPA, etc.) and consensus standards (ACGIH, ANSI, NFPA).
Expertise in exposure assessment strategies and statistical data analysis for interpreting sampling results and determining exposure profiles.
Strong understanding of toxicology and the health effects associated with chemical, physical, and biological agents.
Competency in managing comprehensive safety programs such as Respiratory Protection (including qualitative/quantitative fit-testing), Hearing Conservation, and Hazard Communication.
Knowledge of the hierarchy of controls and experience designing or recommending engineering controls, particularly local exhaust ventilation (LEV).
Proficiency in using industrial hygiene software for data management, analysis, and reporting (e.g., Medgate/Cority, VelocityEHS).
Experience conducting ergonomic risk assessments using established methodologies (e.g., RULA, REBA, NIOSH Lifting Equation).
Familiarity with laboratory analytical methods and quality assurance/quality control (QA/QC) procedures for sample submission.
Ability to read, interpret, and translate complex technical documents, such as Safety Data Sheets (SDS) and toxicological studies, into practical workplace guidance.

Soft Skills

Excellent written and verbal communication skills, with a talent for conveying complex technical information clearly to diverse audiences, from shop floor employees to senior executives.
