Kagan Yavuz Commented on November 27, 2024 Q4 should be 6 db : As one gets closer, the SPL increases. In a wide-open space where the sound does not reflect off any surfaces (no reverberation), the SPL decreases by roughly 6 dB every time the distance from the source is doubled (NFPA FPH 14-30).

Kagan Yavuz Commented on November 27, 2024 The answer of question 2 should be "B": Dusts of organic materials such as wood, food products, paper, and so on of the correct particle size with a depth of less than 1 /8 in. (3 mm) can, under the right set of conditions, result in a flash fire or explosion (see FPH pg 11-31) Anonymous
