3+ years of IH experience in mining, heavy industry, or process manufacturing (underground hard‑rock preferred).
Demonstrated proficiency with air/dust/noise sampling methods and IH instrumentation; ability to interpret analytical results and regulations.
Working knowledge of MSHA (metal/nonmetal) and OSHA requirements applicable to IH, respiratory protection, hearing conservation, hazard communication, and recordkeeping.
Strong communication skills: able to train diverse audiences and collaborate across departments.
Valid driver’s license: ability to work underground and on rotating schedules as required.
Wear required PPE, including respirators; pass fit testing and medical evaluations associated with respirator use.
Walk on uneven surfaces; climb ladders/stairs; lift and carry up to 40 lbs.
Workdays may include off‑shift, weekends, and on‑call rotations to support operations and emergencies.

Nice To Haves

CIH (Certified Industrial Hygienist) or progress toward certification.
Experience with underground mine ventilation concepts, diesel particulate controls, and silica/dust mitigation.
Experience administering Respiratory Protection and Hearing Conservation programs.
Familiarity with ergonomics in mining/processing environments and office settings.
Proficiency with IH data systems and Microsoft 365 (Excel, SharePoint, Teams, Power BI).

Responsibilities

Own the development, implementation, and continuous improvement of the site IH Program, aligning with MSHA (30 CFR) and applicable OSHA (29 CFR) regulations, as well as company policies and industry best practices.
Maintain and update the site IH Written Plan(s), procedures, and annual objectives; coordinate with Mine, Mill, Paste/Backfill, and Maintenance leadership for effective execution.
Serve as the subject‑matter expert for exposure assessment, controls selection, and hazard communication.
Plan and perform IH monitoring for airborne contaminants (e.g., respirable dust, silica, diesel particulate, welding fumes, metals), gases/vapors, and physical agents (e.g., noise, heat/cold stress).
Conduct personal and area sampling underground and in surface facilities (mill, filter plant, paste plant), using validated methods and calibrated instruments.
Analyze sampling data, compare it to regulatory and internal limits, and prepare actionable reports with control recommendations.
Maintain chain‑of‑custody, analytical lab coordination, data management, and documentation.
Recommend and verify effectiveness of engineering/administrative controls and PPE to reduce exposures below applicable limits.
Collaborate with Mine Engineering and Ventilation teams on airflow, dust control, DPM reduction, local exhaust, and auxiliary ventilation effectiveness in production, development, and maintenance areas.
Support housekeeping, wet methods, suppression systems, and process enclosure improvements.
Administer the Respiratory Protection Program (selection, medical clearance coordination, fit testing, use, care, storage).
Conduct qualitative/quantitative fit testing; maintain required records and corrective actions.
Train employees and supervisors on proper respirator use and limitations.
Lead the Hearing Conservation Program (noise surveys/dosimetry, audiometric tracking liaison, controls, training).
Perform ergonomic assessments for office and field tasks; recommend practical, low‑cost solutions and equipment adjustments to reduce MSD risks.
Assess additional physical agents (vibration, thermal stress, illumination) and implement controls and training as needed.
Maintain the chemical inventory/SDS system; review new product approvals; assist with safe handling, storage, and labeling.
Develop and deliver Hazard Communication training and toolbox talks; verify understanding and compliance in the field.
Support the site Drug & Alcohol program administration (policy communication, testing logistics with third‑party providers, documentation, trending, and confidentiality).
Coach supervisors on reasonable suspicion processes and documentation requirements.
Develop and deliver IH‑related training for new hires and experienced employees (annual refreshers, task‑specific instruction, changes in controls/PPE).
Create concise reports, dashboards, and safety alerts; communicate findings and corrective actions to leaders and crews.
Participate in accident/incident and near‑miss investigations for health‑related issues (e.g., suspected overexposures, suspected occupational illness, hearing threshold shifts).
Conduct root‑cause analyses and track corrective and preventive actions to closure; verify effectiveness.
Maintain complete and accurate IH records (sampling plans, results, calibration logs, training, fit tests, corrective actions) in accordance with MSHA/OSHA and company requirements.
Prepare IH metrics and present at leadership meetings; support required regulatory reporting.
