Dangers of using flexible hoses for bottled ether
Thread Content
A small amount of ether is produced as a by-product; it used to be transported in tank trucks using flexible hoses. Due to the small quantity, it is now supplied in barrels (200kg per barrel). The method currently considered is to use a flexible hose to insert into the barrel in order to fill it. The weight is indicated by a scale; filling is carried out by gravity flow through the operation of the two valves in front of the dip pipe. 1. It is always felt that the risk is too high, and the greatest danger comes from human factors. Friction between the flexible hose and the barrel generates sparks ； Due to human negligence, ether leaked out ； Harm to personnel caused by ether evaporation ； 2. It is definitely also non-compliant; I’m not sure if there are any relevant regulatory requirements. Please ask the teachers to help answer
Could you please tell me what the specific regulatory requirements are?

With buckets of 200 kg capacity, it takes just over two minutes to fill one bucket; even at a flow rate of 0.5 m/s, it still only takes 5 minutes, which makes the operation very inconvenient. If a small pipe is connected at the flexible hose connection, your loading pump is still too large for 200kg barrels; and since the barrels need to be stored, isn’t it necessary to have a warehouse for that purpose? In accordance with GB50160 6.5.4, the storage area for actual bottles (barrels) and the filling room can be located in the same building, but it is advisable to separate them with solid walls, with separate entrances and exits for each. Therefore, you can use a solid wall to create a filling room in the Class A warehouse you have prepared, purchase a filler machine, and then send the products directly to the warehouse for storage.
It needs to be installed on Friday; we’ll see how to do it then.
