1.1. Assess the suitability of the shop (ie the respective needs and the actual air) capacity for work, during which the released CO, ethylene, ammonia, sulfur dioxide, as well as the Q J / h waste heat.
Volume management - V1 = 1600 m2
G1 = 98 g / hr (CO)
G2 = 2,3 g / h (ethylene)
G3 = 6 g / h (ammonia),
G4 = 55 g / Hr (sulfur dioxide)
Q 2 = 6,91 × 106 J / h (excessive heat).
K = 5 (Number of air)
The supply air temperature is 23 0C t1 =
The temperature in the working zone is t2 = 27 0C. Exhaust holes are located at a height of 5 meters from the work site.
PDKSO = 20 mg / m3;
PDKS2N2 = 1 mg / m3;
PDKNH3 = 20 mg / m3;
PDKSO2 = 10 mg / m3.
2.2 The challenge for the independent solutions.
To calculate the total artificial (fluorescent) lighting by utilization of light flux in the room
Room dimensions: length a = 5 m, width b = 4 m, height suspension lamp h = 3 m, the reflection coefficients of the walls and ceiling s = 50% = 70% p.
Safety factor K = 1.3.
Irregularity ratio Z = 1,1.
Number of lamps in the luminaire - 2. The length of the recommended series LSPO1 lamp, designed for two fluorescent lamps is equal to 1,536 m.
Rank visual work - IV - medium accuracy
Assess the conditions at the workplace noise.
Duration -8ch change.
Calculate the level of noise intensity in an area where there are three non-directional source.
Humidity is 80%.
Determine the effectiveness of the human dose
The irradiated organs - the gonads (sexual glands). Equivalent dose - q1 = 250 mSv.
The irradiated organs - intestines. Equivalent dose - q2 = 720 mSv.
