What ISN is, in one paragraph

ISNetworld is a Dallas-based contractor-compliance platform. Industrial owners pay a subscription, define the safety, insurance, and training thresholds their site requires, and use ISN to vet every contractor they hire. Contractors pay an annual fee, submit documentation, get a graded profile, and become visible to every ISN-subscribing buyer. The shorthand "ISN-certified" is what shows up in RFPs; ISN's own term is "accredited" or "in compliance." Same working meaning: this contractor has been audited and is cleared for the site. For a per-bucket walkthrough of insurance, OSHA stats, MSAQ, RAVS, and training records, see our deeper guide: ISN certification for security integrators: what buyers expect.

What you save by hiring an accredited integrator

Four concrete things change the day you sign with an ISN-accredited shop instead of a generic integrator:

  • Procurement clears the vendor in days, not weeks. The insurance certs, OSHA logs, and safety plans your buyer would normally chase are already on file at ISN with grades attached. Your EHS team checks the profile and signs off.
  • Liability exposure drops if a tech gets hurt. An accredited contractor brings PPE on day one, runs a written job hazard analysis per site, and carries the insurance limits your MSA requires. The "we didn't know they didn't have a fall-protection program" failure mode is closed.
  • Install kickoff doesn't slip three weeks. Most non-ISN delays come from documentation chasing, not installation. Accredited shops ship pre-cleared, so the schedule starts when you sign.
  • Auditor and inspector visits go smoother. When an OSHA inspector shows up or your insurer audits site practices, the integrator's safety program is already documented and graded.

What ISN actually verifies

The audit is mostly documentation review with grading layered on. The major buckets:

  • Insurance. General liability, auto, workers comp, umbrella, specialty coverage. $5M umbrella is a common ask on industrial sites.
  • OSHA stats. TRIR (Total Recordable Incident Rate), DART rate, fatalities, lost-time injuries by year. Below 1.0 TRIR is broadly competitive in low-voltage work.
  • MSAQ. A roughly 200-question Management System Assessment covering hazard communication, fall protection, hot work, electrical safety, confined space, lockout-tagout, PPE, and incident reporting.
  • RAVS. ISN's Review and Verification team reads each written safety plan and grades it A through F against your specific buyer requirements.
  • Training records. OSHA 10, OSHA 30, first aid, CPR, plus any site-specific training (TWIC for ports, NFPA 70E for high-voltage).
  • Drug and background. Written policies plus a sample of recent records.

None of these are checkbox items. RAVS in particular is where many contractors lose ground. A generic OSHA template won't grade well against a refinery operator's expectations.

If your shortlist isn't on ISN, ask for these six things in writing

If you're considering a non-ISN integrator because they're priced well or you've worked with them before, you're now responsible for the audit ISN would have done. Ask for:

  1. Three years of OSHA 300 logs with calculated TRIR and DART rates.
  2. A written safety program covering hazard communication, lockout-tagout, fall protection, electrical safety, PPE, and incident reporting.
  3. OSHA 10 or OSHA 30 training records for every tech who'll touch the site.
  4. Certificates of insurance with your facility named as additional insured, including waiver of subrogation.
  5. A written drug and background screening policy plus a sample of recent records.
  6. Three recent project references in a comparable industrial setting.

If the integrator delivers all six in 48 hours, they're running a real safety program and just haven't joined ISN. If anything takes a week or comes back fuzzy, that's the signal you'd have caught with ISN in the first place.

How Tec-Tel approaches ISN-grade buyers

Tec-Tel operates with the safety, insurance, and documentation discipline industrial buyers require. Our standard install package produces what your procurement team expects: insurance certs naming the buyer additional insured, OSHA-aware install practices, written job hazard analyses per site, certificates of training for the techs on site, and a per-site bill of materials with vendor self-certifications attached.

Tec-Tel is trusted by industry leaders including Bridgestone, ORBIS, TreeHouse Foods, and Menasha. The common pattern: a procurement lead with an ISN-managed approved-vendor list and an inherited security stack from three different integrators, looking for one accountable shop to take the whole footprint.
