Example of Regional Description
During normal operation, Zone 21 experienced an explosion in the air
Explosive environment in the form of combustible dust clouds
Places where states may or occasionally occur.
A total of combustible dust clouds appear annually
Between 10 and 1000 hours;
When explosive dust/air mixtures appear inside the dust, frequent movement or opening of the nearest inlet is necessary for operation
External locations of dust containers for going out;
When taking measures to prevent the formation of explosive dust/air mixtures, close to the loading and unloading points
External locations of dust containers such as conveyor belts, sampling points, truck unloading stations, and belt unloading points;
If dust accumulates and due to process operations, the dust layer may be disturbed to form explosive dust/air mixtures
When outside the dust container;
In dust containers where explosive dust clouds may occur (but neither continuously, for a long time, nor frequently)
Places such as silos with long self cleaning intervals (if only occasionally loading and/or discharging) and
The accumulation side of the filter.
During normal operation, Zone 22 experienced an explosion in the air
Explosive environment in the form of combustible dust clouds
Places where states are impossible to occur, if
It is currently only a place that exists for a short period of time.
A total of combustible dust clouds appear annually
Less than 10 hours;
The exhaust port of the bag filter ventilation hole may release explosive mixtures in case of malfunction;
Near equipment that is not frequently opened, or near equipment that is prone to leakage due to dust blowing out based on experience, such as pneumatic equipment
Equipment or potentially damaged flexible connections, etc; ——-A storage bag containing a lot of dust products. During operation,
The storage bag may malfunction, causing dust dispersion;
When measures are taken to prevent the formation of explosive dust/air mixtures, those generally classified as Zone 21 can be reduced to Zone 22
District venue. This type of measure includes exhaust ventilation. At the loading and unloading points of the dust bag, the feeding belt, and the sampling point
Measures should be taken near truck unloading stations, belt unloading points, and other locations;
The controllable (cleanable) dust layer formed may be disturbed and generate explosive dust/air mixtures in the field
So. Only by cleaning the dust layer before the formation of hazardous dust/air mixtures, can it be removed
It is a non hazardous location. This is the main purpose of good on-site cleaning.
