First we consider the installation and housing of electrolyzers. We address very briefly the comparative advantages of indoor and outdoor installation of electrolyzers and then turn to the characteristics of buildings and the arrangements appropriate to the various types of cell. A description of some of the design considerations of the cell line working zone, especially those related to electrical safety, follows. Building ventilation is then considered separately, with mercury-cell installations as a special case. 

A. Cell Line Working Zone. Operators must perform many of their routine duties in close proximity to the cells, and many maintenance activities also take place while the circuit is energized. Many ordinary design precautions do not apply inside cell installations. The entire line, for example, cannot be enclosed and isolated as are the transformers and rectifiers. This approach would trap gases and heat and make some of the necessary manual operations impossible. There is, instead, a collection of practices that apply in what is referred to as the cell line working zone (CLWZ).
