Unfortunately exclusions will still exist in CSA Z462, although Mining may get an exclusion. This information can be viewed at

FYI, the following was released by CSA today:

CSA Z462 Stakeholders:

As part of our commitment to keep you informed of the Z462 project, please note the following;

The Z462 Workplace Electrical Safety Technical Committee decided at their meeting on October 15 in Calgary that the Scope of CSA Z462 will adopt the sector exclusions contained in Section 90.1 of the Scope of NFPA 70E (2004 Edition). However the Committee also decided to review the proposed mining sector exclusion (Exclusion Item #2) with Canadian stakeholders. For your reference following is a copy of those exclusion statements.

NFPA 70E, Article 90.1(B)

This standard does not cover the following:

1. ]Installations in ships, watercraft other than floating buildings, railway rolling stock, aircraft, or automotive vehicles other than mobile homes and recreational vehicles;
2. Installations underground in mines and self-propelled mobile surface mining machinery and its attendant electrical trailing cable;
3. Installations of railways for generation, transformation, transmission, or distribution of power used exclusively for operation of rolling stock or installations used exclusively for signaling and communications purposes;
4. Installations of communications equipment under the exclusive control of communications utilities located outdoors or in building spaces used exclusively for such installations
5. Installations under the exclusive control of an electric utility where such installations:
a. Consist of service drops or service laterals, and associated metering, or

b. Are located in legally established easements, rights-of-way, or by other agreements either designated by or recognized by public service commissions, utility commissions, or
c. other regulatory agencies having jurisdiction for such installations, or
d. Are on property owned or leased by the electric utility for the purpose of communications, metering, generation, control, transformation, transmission, or distribution of electric energy.
