The independent RF expert your insurer, attorney, and board want to see on the file.

What we do

OSC Engineering — Occupational Safety & Compliance Engineering — provides Radio Frequency (RF) Electromagnetic Emissions (EME) technical services to property owners, school districts, local jurisdictions, and wireless operators who need to verify and document compliance with FCC RF exposure limits.

The FCC sets human exposure limits to RF energy under 47 CFR § 1.1310 and details the methods for evaluating compliance in FCC OET Bulletin 65. Wireless operators are required to perform compliance studies — but the property owner or jurisdiction often has no independent way to verify the numbers, the assumptions, or the proposed mitigations.

That’s where we come in. We measure, model, document, and train. We don’t sell carrier services. We don’t take referral fees from operators. The report you get is the report that holds up.

Who we work with

We serve four primary client groups, each with a different need but the same underlying question: “Is this site safe, and can I prove it?”

• Property owners with rooftop antennas or ground-mount monopoles who need to verify their tenant carriers are within compliance and that their own workers (HVAC, roofers, maintenance) are protected.
• School districts facing parent or community concerns about cell sites near schools, especially when a new lease, modification, or co-location is proposed.
• Local jurisdictions — planning departments, zoning boards, and elected officials who need an independent technical opinion on proposed wireless installations.
• Wireless operators & contractorswho want a third-party compliance study, RF safety training for crews, or an independent review of a site they’re inheriting.

Our principal

Craig VanDykeleads OSC Engineering. He’s spent his career inside the FCC RF compliance world — reading the rules, walking the sites, and translating dense regulatory language into mitigations people can actually execute. He knows the difference between an Occupational/Controlled environment and a General Population/Uncontrolled environment matters not in theory but in the very specific question of who’s standing on which side of the lockout when the antenna is energized.

That’s the kind of detail an annual compliance study should catch — and most of the time it doesn’t.

The OSC promise

• Independent. No carrier equity, no kickbacks. We work for whoever wrote the check.
• Rules-cited. Every report quotes the applicable FCC, OSHA, and ANSI/IEEE provisions so a reader can verify the work.
• Plain-English.The 47 CFR is a hard read. The OSC report isn’t.
• Photo-documented.If we said the antenna is 14’ from the walking surface, we show you the photo with the tape measure.
