2.2.3 Ambient conditions
Suitable measures must be taken by the operator to mitigate explosion hazards due to firedamp and the ignition of dust which might occur in a mine. That includes:
adequate and consistent ventilation water spraying system
If the firedamp concentration in the free cross-section of the parts of the face which are continuously ventilated reaches a percentage of the lower explosion limit (LEL) defined by applicable national legislation, the M2 device must be switched off. The limit values can be found in your national laws.
DANGER Explosion hazard
The power to the supply cable and control system cable must be switched off if the local gas concentration in the mining equipment areas exceeds the permissible parameters given in the safety regulations for coal mines.
It may only be restarted by an authorized person.
The atmosphere in the mine should be monitored at hazardous points to allow the power supply of all devices to be switched off, except those which are relevant for safety and suitable for use in explosive atmospheres.
The M2 equipment must be stopped immediately and secured against restarting if the firedamp protection systems are found to be damaged.
The control and peripheral equipment of the MMC system with appropriate explosion protection marking are intrinsically safe and manufactured according to the approved technical regulations.
The use of components with appropriate explosion protection marking has no effect on the safety regulations and the regulations concerning firedamp protection at the mining company.
You may only open live control units in an environment which is not potentially explosive, even if there is no voltage. Observe the instructions on the device housings.
2.2.4 Prerequisites for operation
The entire PMC system must not be put into service until it has been determined by an appropriately trained and authorized person that the machine controlled by the system complies with European Directive 2014/34/EU and the DIN EN1710 standard.
