WorkSafeBC issued the bulletin “Working around microwave radiation from rooftop antennas” last August. WorkSafeBC Bulletin
Early in 2015, Health Canada revised the exposure limits for Radiofrequency (RF) Electromagnetic Energy. As a result, testing companies are contacting employers to promote their services to conduct RF surveys.
The WorkSafeBC Bulletin notes Engineering Controls to protect workers include using physical guards or barriers to restrict access to areas near antennas, and to raise the antennas above the working level of the roof as the lowest level of radiation is directly beneath the antennas. Administrative Controls are also listed in the Bulletin, and include using signs and/or caution tape to indicate high radiation areas, and maintaining at least a 3 meter distance from an antenna.
Please review the WorkSafeBC bulletin and note that as the employer or as a property owner, you are responsible for ensuring worker exposure is kept below the values issued by Health Canada. Health Canada’s Safety Code 6 for RF Exposure limits can be found here: RF Exposure Limits 2015
