Postavitev razdelilnih prostorov znotraj protieksplozijsko varnih con ni priporočljiva, saj ne le poveča investicijske izdatke, ampak tudi poveča tveganje za nesreče.
Po “GB50160-2014 Standardi za projektiranje požarne zaščite stavb”, V delavnicah razreda A je prepovedano gostiti pisarne ali distribucijske prostore. V primerih, ko je posebna distribucijska soba nujna, it should be placed adjacent to a wall with an imperative for the dividing wall to be explosion-proof.
Control rooms, cabinet rooms, and electrical distribution and substations ought to be situated beyond the explosion hazard zones, ensuring ample safety margins. In these areas, the electrical equipment is exempt from explosion-proof requirements. This approach is widely adopted across the majority of chemical industry facilities today.
