Emergency Power off switch

Emergency Power off switch

(OP)
Is there anyone aware of a regulation in Canada and Australia that would prohibit the use of 2 contacts in the same Emergency power off push button to deactivate two separate 24 vac control circuits for contactors?.
The application is an AC power supply which input and output are controlled by magnetic contactors.
Thank you
Victor
