Safety Code 6 (SC6) Assessment for School Boards in Canada

Ensuring RF Exposure Compliance in Connected Learning Environments

As schools across Canada continue to adopt connected technologies, wireless infrastructure has become an essential part of the modern learning environment.

Wi-Fi networks, wireless communication systems, distributed antenna systems (DAS), cellular infrastructure and other RF-emitting equipment can all contribute to the radiofrequency (RF) environment within and around a school facility.

For school boards, understanding and evaluating this RF environment is an important part of responsible infrastructure planning and safety management.

The Challenge

A Canadian school board engaged Red Oak Technologies to conduct a Safety Code 6 (SC6) RF exposure assessment associated with wireless infrastructure serving a school facility.

The objective was to determine whether RF exposure levels in areas accessible to students, teachers, staff, visitors and other members of the public were within the applicable Health Canada Safety Code 6 limits.

The assessment needed to consider the site’s wireless environment rather than looking at individual RF sources in isolation.

This is particularly important because multiple RF sources can contribute to the overall exposure environment.

What is Safety Code 6?

Health Canada’s Safety Code 6 establishes recommended limits for human exposure to radiofrequency electromagnetic fields in the frequency range from 3 kHz to 300 GHz.

The guidelines are designed to protect people, including members of the general public and workers, from established adverse health effects associated with RF exposure.

Safety Code 6 covers RF sources associated with technologies such as Wi-Fi, cellular communications and 5G.

For wireless infrastructure subject to ISED requirements, compliance with Safety Code 6 is an important part of RF exposure evaluation.

Red Oak’s Approach

Red Oak Technologies approached the school board assessment as an engineering evaluation of the site’s overall RF environment.

The assessment included:

1. Review of RF Sources

The first step was to identify the relevant RF-emitting equipment and available technical information.

This can include:

• Wi-Fi access points

• Cellular antennas

• DAS equipment

• Wireless communication systems

• Nearby RF sources

• Transmitter operating parameters

• Antenna characteristics and locations

  
  

Understanding the local RF environment is essential because exposure from multiple sources may need to be considered collectively.

ISED’s antenna-system procedures specifically require consideration of the combined effects of nearby installations within the local radio environment.

2. RF Exposure Evaluation

Depending on the project requirements and available information, an SC6 assessment can involve engineering calculations, modelling, field measurements, or a combination of these approaches.

ISED’s GL-08 guidelines identify theoretical calculations, measurement results and corrective measures as methods that can be used to demonstrate compliance with Safety Code 6.

For this school-board project, Red Oak evaluated the relevant RF sources and assessed exposure in areas accessible to the general public.

3. Assessment of Publicly Accessible Areas

Schools present a unique environment because many areas are accessible to children, teachers, administrative staff and visitors.

The assessment therefore considered areas such as:

• Classrooms

• Hallways

• Common areas

• Gymnasiums

• Offices

• Outdoor areas

• Rooftops or restricted areas, where applicable

• 
  

Health Canada’s technical guidance distinguishes between controlled and uncontrolled environments and provides guidance for evaluating RF exposure through measurements, calculations and modelling.

4. Compliance Documentation

The findings were documented in an engineering report designed to provide the school board with a clear understanding of the site’s RF environment and its compliance status.

An effective RF exposure report should clearly identify the methodology, relevant RF sources, assumptions, results and applicable compliance conclusions.

ISED’s GL-08 guidance specifies key information to be included in RF exposure compliance reports, while GL-01 provides guidance for RF field measurements and references GL-08 for reporting measurement surveys.

Why SC6 Assessments Matter for Schools

Wireless technology is now an integral part of education.

Students and staff rely on:

• High-density Wi-Fi

• Connected classroom technology

• Wireless laptops and tablets

• Voice and communication systems

• Mobile networks

• IoT-enabled building systems

• Emergency communication systems

  
  

As wireless infrastructure evolves, school boards need reliable engineering information to understand the RF environment within their facilities.

An SC6 assessment provides an evidence-based way to evaluate RF exposure against applicable Canadian guidelines.

Beyond Compliance

For a school board, an SC6 assessment is not simply about producing a report.

It can also support:

Infrastructure planning Understanding the existing RF environment can help inform future wireless deployments.

Facility management RF assessments can provide useful documentation when wireless equipment is added, relocated or upgraded.

Project coordination Engineering assessments can help coordinate multiple wireless systems and RF sources.

Risk management A documented assessment provides the school board with technical information regarding RF exposure in areas accessible to the public.

Future technology upgrades As Wi-Fi, cellular, DAS and other wireless technologies evolve, existing RF assessments can provide a useful baseline for future evaluations.
