(c) to be, as far as is practicable, constructed so as to be proof against rodents, leakage, seepage and flooding;
(d) to be provided with lighting that will enable all equipment, thoroughfares and working areas to be clearly distinguished and all instruments, labels and notices to be easily read;
(e) to have doors or gates, which can be readily opened from the inside, opening outwards;
(f) to be provided with fire extinguishing appliances or systems which are suitable for use on electrical machinery and which are maintained in good working order: Provided that, in the case of unattended premises, suitable fire extinguishing appliances be made available at such premises only when work is in progress thereon or therein; and
