her rtified and checked for its operational period. The site should be equipped with fire and smoke rs with sensors activating the external alarm mechanism. Extra harnesses should be available for the nance engineers who take care of the towers and fitted antennas. A battery-operated emergency would be available in case of any power outages. Exits should be clearly marked in case of an ncy clearance procedure. The mains distribution board and the circuit breakers should be well reach of a normal person and within sight, SO that they can be turned off or reset in case any electrical problem occurs. There should be antistatic mats and wristbands available on site for nance engineers to perform operations on the live hardware without risking any static electricity ges. The towers should have lightning arrestors. The site, including all electrical equipment, should common functional grounding system. For maintenance purposes there should be a microwave nication phone available on the site; for instance, if somebody is locked in or if the cell site fails coverage is available then the alternate system can be used to relay a distress call to the main ons centre.
