Specifically in the:

https://laws-lois.justice.gc.ca/eng/regulations/C.R.C.,_c._1370/index.html

SCHEDULE II (Section 3)

  • (d) it must bear the words “CAUTION: X-RAYS — ATTENTION : RAYONS X”; and
  • (e) it must conform to one of the following:
    • (i) the X-ray warning symbol:
    • Warning symbol consisting of an inverted triangle that contains a tube with a circle in the middle of it from which three dashed lines emerge.
    • (ii) the symbol ISO 361 in the report of the International Electrotechnical Commission entitled Graphical symbols for electrical equipment in medical practice, Publication IEC TR 60878: 2015, Third Edition, illustrated as follows:
    • Warning symbol consisting of three black blades around a black circle.
    • (iii) the symbol ISO 7010-W003 in the report of the International Electrotechnical Commission entitled Graphical symbols for electrical equipment in medical practice, Publication IEC TR 60878: 2015, Third Edition, illustrated as follows
    • :Warning symbol consisting of a yellow triangle bordered by a black line and containing three black blades around a black circle.

Combining the text requirement with the graphic and excluding the bilingual text is usually allowed, resulting in the use of a graphic such as the one below. The regulations do not specifically allow this, but there do not seem to be objections to it being used:

or more appropriately:

ONTARIO:

In addition, regulations for devices installed in Ontario are defined in the H.A.R.P Act:

Healing Arts Radiation Protection Act.
Regulation 543
X-Ray Safety Code

Located at: https://www.ontario.ca/laws/regulation/900543


9.
(1) Every diagnostic X-ray machine shall bear either on the external surface of the main X-ray control panel or at the exposure switch location a warning sign that indicates that,
(a) unauthorized use is prohibited; and
(b) hazardous radiation is emitted when the X-ray machine is activated.

In summary: Every dental X-ray emitting device in Ontario should be identified with the graphic defined in the RED Act printed 2cm x 2cm or large with the CAUTION: X-RAYS text, along with the two lines of text required in Section 9 of the HARP act. This is shown below:

X-ray devices in Ontario that are used for purposes other than dental/medical are subject to the Occupational Health and Safety Act – R.R.O. 1990, Reg. 861: X-RAY SAFETY and not the H.A.R.P. Act. Information can be found at: https://www.ontario.ca/laws/regulation/900861
