If any leakage is detected in the joints of filter it shall be repaired with the food-quality silicon and leak web page shall be rescanned.
The next method of basically get rid of the potential for a here spark or other source of ignition. This may be achieved by trying to keep the temperature small, keeping all electronics safe or making use of a device that doesn't generate enough warmth or electrical present to produce combustion when while in the presence of the flammable material.
