Part 36 Mining

Section 538 Light metal alloys

(1) An employer must ensure that, if it is reasonably practicable, workers do not take into an underground coal mine or other hazardous location light metal alloys that

(a) contain more than 15 percent aluminum by mass of the alloy or more than 15 percent aluminum, magnesium and/or titanium, taken together, by mass of the alloy, or

(b) contain more than 6 percent magnesium and/or titanium taken together or separately, by mass of the alloy.

(2) Despite subsection (1), an employer may permit workers to take and use equipment with alloys that contain light metals into a hazardous location if the equipment has protective design features that minimize the potential for incendiary friction or sparking.

(3) An employer must ensure that fan blades for auxiliary or booster fans to be used in an underground coal mine and that do not comply with subsection (1) are

(a) adequately coated with non-sparking material,

(b) inspected by a competent person each time they are moved, or at least every 6 months, and a record of these inspections is kept at the mine,

(c) taken out of service if the coating is damaged.

(4) This section also applies to hazardous locations at the surface of an underground mine.
