Professional Credentials
Stuart D. Bagley, MS, CIH, CSP, is a Board‑Certified Industrial Hygienist and Certified Safety Professional with 30+ years in environmental health and safety. A former Federal OSHA Compliance Officer and corporate safety manager, he leads IAQ‑EMF Consulting Inc. in delivering rigorous EMI/EMF testing for healthcare, industrial, and institutional clients across the U.S. and Canada.
Overview
Electromagnetic interference (EMI) can affect both people and equipment. For individuals with pacemakers, defibrillators, or neurostimulators, EMI can trigger malfunctions or discomfort. In industrial plants, elevated fields can degrade controls, trip protection systems, or interrupt sensitive processes. Our role is to measure, analyze, and mitigate these risks so healthcare and facility teams can maintain safe, reliable operations.
Medical Implant Safety Assessments
We align field measurements with device‑manufacturer guidance for implantable cardiac devices and neurostimulators, documenting conservative approach distances and task‑specific recommendations that clinical and occupational health staff can implement immediately.
Industrial and Plant Equipment
Manufacturing plants, utilities, and laboratories operate complex systems—from drives and PLCs to imaging and welding equipment—that are vulnerable to EMI. We evaluate electrical rooms, production floors, and research areas to determine where fields could disrupt operations and how to prevent recurrence.
Equipment Reliability & Uptime
When risks are identified, we recommend practical controls such as equipment re‑orientation, improved bonding/grounding, selective shielding, and operating schedule adjustments to stabilize production and reduce downtime.
Healthcare Applications
In hospitals and clinics, medical devices must function without interference. We perform targeted EMI assessments that verify whether staff and patients with implants can safely occupy areas near MRI suites, induction heaters, welders, RF dryers, or other high‑field sources.
How We Work
Each engagement starts by clarifying objectives—worker safety, equipment reliability, or both. We develop a measurement plan, apply calibrated instrumentation, and capture real‑time field strengths under relevant operating conditions. Reports interpret results in plain language, relate them to applicable thresholds, and prioritize next steps.
Methods, Calibration, and References
Our approach includes task‑based measurements, gradient mapping near sources, and uncertainty considerations. Instrument calibration is current and traceable. We reference IEEE/ICES and ICNIRP exposure guidance, FCC/ISED rules for RF sources, and device‑manufacturer instructions for medical implants.
Deliverables
Deliverables include an executive summary for leadership, detailed tables and figures for engineers and biomedical teams, and practical recommendations that can be implemented by maintenance and clinical staff. Documentation is structured so findings are easy to brief and act upon.
Service Areas
We support projects throughout the United States and Canada. Remote reviews are available for planning and urgent triage, with rapid on‑site response when field measurements are required.
