Fire-fighting gaps between alcohol storehouses of production buildings and
constructions depending on their degree of fire-resistance, are given in table 1[13].

Notes:
1. Gaps to buildings and constructions of the III-rd, IV-th, V-th degree of fire-resistance are
received only for operating enterprises during their reconstruction.
2. Gaps to the administrative and consumer buildings as well as the buildings of the categories
A and B should be widened by 25 %.
3. Distances from buildings and constructions aren’t standardized to closed and open alcohol
storehouses (sheds) for HIL (Highly Inflammable Liquids) with capacity up to 100 m

Minimum distances from the walls of ground reservoirs and closed alcohol
storehouses to reception and supplying, pouring out and pouring in devices of the
railway gauges and motor-car roads must meet the requirements, given in table 2 [13].
