### sec.354 Provision for fans in principal hazard management plan for ventilation An underground mine’s principal hazard management plan for ventilation must state— for a main exhausting fan— the general body concentration of methane in the ventilating air passing through the fan that must not be exceeded before a methane detector monitoring the air automatically activates a visible alarm; and the action to be taken if the alarm is activated; and if a booster fan is used at the mine— the procedures for using the fan; and the action to be taken if a methane detector monitoring the air passing through the fan activates a visible alarm. - (a) for a main exhausting fan— (i) the general body concentration of methane in the ventilating air passing through the fan that must not be exceeded before a methane detector monitoring the air automatically activates a visible alarm; and (ii) the action to be taken if the alarm is activated; and - (i) the general body concentration of methane in the ventilating air passing through the fan that must not be exceeded before a methane detector monitoring the air automatically activates a visible alarm; and - (ii) the action to be taken if the alarm is activated; and - (b) if a booster fan is used at the mine— (i) the procedures for using the fan; and (ii) the action to be taken if a methane detector monitoring the air passing through the fan activates a visible alarm. - (i) the procedures for using the fan; and - (ii) the action to be taken if a methane detector monitoring the air passing through the fan activates a visible alarm. - (i) the general body concentration of methane in the ventilating air passing through the fan that must not be exceeded before a methane detector monitoring the air automatically activates a visible alarm; and - (ii) the action to be taken if the alarm is activated; and - (i) the procedures for using the fan; and - (ii) the action to be taken if a methane detector monitoring the air passing through the fan activates a visible alarm.
