Statement As a result of an accident at the neighboring industrial unit the staff of the machine-building plant may be found at the contaminated area (chemical, radioactive contamination etc.). To prevent staff affection two protective shelters were built at the territory of the machine-building plant. Task To evaluate protective shelters reliability according to the initial data listed in the table 18.1: 1. to determine if there would be enough place for the staff in the both protective shelters; 2. to determine if ventilation and air cleaning systems maintain air feed continuity according to the current specification; 3. to determine if water supply is sufficient in the both protective shelters. Report 1. student's first name, second name, group and variant; 2. seating capacity calculated for the area index: ... persons; M 12 = ... persons; 3. seating capacity calculated for the volume index: M vi = ... persons; M2= ... persons; 4. minimum seats amount in the protective shelters: M mini = ... persons; M min2 = ... persons; 5. actual seats number in the both protective shelters : M ... persons; M,= ... persons; 6. number of the seats in the l' air duty: N' ... persons; N';= ... persons;; 7. number of the seats in the 2nd air duty: ... persons; N, = ... persons; 8. number of the seats in the 3rd air duty: N, ... persons; N', = ... persons; 9. number of the seats supplied by the water: = ... persons; Nw2 = ... persons; NI = NwI To obtain seating capacity calculated for the area index it's euwder sening capretty necessary to use formula 18.1: Sh S. (18.1) where: M - seating capacity calculated for the area index; S. - area of the protective shelter facility, m; S mor-space requirements (per person): Shor=0.5 m, if floor-to-ceiling height is 2.15- 2.9 m, and S = 0.4 m, if floor-to-ceiling height is more than 2.9 m). To obtain seating capacity calculated for the volume index it's necessary to use formula 4.2: M (S +5 at (182) where: M. - seating capacity calculated for the volume index: S.A-area of the protective shelter facility, m; Sar-area of additional protective shelter facility, m'; h-floor-to-ceiling height, m; - air volume requirements (per person): V 1.5 m? To obtain number of the seats in the l' air duty it's necessary formula 18.3: Thor ad to use (18.3) where: N, - number of the seats in the 1" air duty: - number of filter installations FU-I and/or FU-2 in the protective shelter; V , - productivity of filter installation in the 19 air duty, m /hour; W ,- air volume requirements (per person) m /hour, depends on the climatic region, where the machine-building plant is situated: I climatic region - 8 m/hour : II climatic region - 10 m/hour; III climatic region - 11 m/hour; IV climatic region - 13 m/hour To obtain number of the seats in the 2nd air duty it's necessary to use formula 18.4: n. W (18.4) where: N,- number of the seats in the 2nd air duty; n - number of filter installations FU-1 and/or FU-2 in the protective shelter; V , -productivity of filter installation in the 2nd air duty, m/hour; W , - air volume requirements (per person) m /hour, for the 2nd air duty, W = 2 m /hour; To obtain number of the seats in the 3rd air duty it's necessary to use formula 18.5: N, - 150-m. (18.5) where: N;- number of the seats in the 3rd air duty; m-number of filter units FU-2 in the protective shelter. To obtain number of the seats supplied by the water it's necessary to use formula 4.6: B B (18.6) where: Ny-number of the seats supplied by the water; B - emergency water ration, liters; B nor - water requirements (per person), liters; T-estimated time of the protective sheltering, days. 103 Table 18.1 1 2 3 4 5 6 7 8 310 340 400 450 480 550 620 670 1 No Parameters Manning level, persons 2 Characteristics of the protective shelters a) area of the protective shelter facility, Shelter m?
