Conduct effective workplace examinations. Identify all hazards and take action to correct them. Ensure all active working areas are ventilated prior to allowing miners to work in those areas. Monitor gasses as frequently as necessary to determine the adequacy of control measures. Use properly maintained and calibrated gas detection instruments with alarms for concentrations outside of safe limits that are audible and visual. Ensure all miners are trained to recognize all potential hazards and emergency procedures, including evacuation procedures.
