Which statement describes ALARA in relation to contaminants?

Explanation:
ALARA means keeping exposure to contaminants as low as reasonably achievable. In coal mining ventilation, this principle is applied to every contaminant listed in schedule 6 column 1, guiding you to implement controls that reduce concentrations to the lowest practical level, balancing safety with practicality and cost. It isn’t limited to methane or to oxygen levels; those are managed as part of different regulatory considerations. Because the regulation requires ALARA for all contaminants in that schedule, that statement best fits the concept.
