Building explosion-proof safety distance

Classification of civil blasting equipment library:

Permanent storage: all kinds of general storages and sub-storages that have been stored and used for more than 3 years;

Temporary warehouse: all kinds of general warehouses, branch warehouses, and distribution stations that have been stored and used for less than 3 years;

Ground storage, buried storage, chamber storage.

The external safety distance between the permanent civilian blasting equipment warehouse and the surrounding villages, residential buildings, factories and facilities (such as highways, waterways and railway lines, high-voltage lines, etc.) is in accordance with the table in the `` Safety Code for Design of Civil Blasting Equipment Factory '' (GB50089-1998) 4.3.2 OK.

For the external safety distance between the temporary civilian blasting equipment warehouse and the surrounding villages, residential buildings, factories and facilities (such as roads, waterways and railway lines, high-voltage lines, etc.), the protection levels of various protection objects should be selected according to Table 2-14 coefficient. Then multiply this coefficient by the distance specified in Table 2-15 to determine.

When multiple warehouses exist at the same time in the warehouse area of ​​civil blasting equipment, an internal safety distance must be set to ensure that there is no martyrdom between the warehouses:

The distance between the A1 grade warehouse or the medicine piles shall not be less than those specified in Table 2-16;

The distance between the A2 level warehouse or the medicine piles shall not be less than those specified in Table 2-17;

The distance between Class A3 warehouses or drug piles shall not be less than those specified in Table 2-18.
