Modern work environments are becoming increasingly sensitive

Buildings are becoming smart. They are based on networked technical components
L K which require a permanent supply of power and data. Today modern commercial
F buildings such as hotels, medical facilities or office buildings are defined by smart
building equipment. As an example, intelligent systems automatically control and
D optimise the energy requirement, arrange for the cleaning of only those areas which
have really been used and control access via sensitive security technology.
E H Failure of individual components, e.g., following lightning strikes and surges, may
I J cause the collapse of all networked systems, bringing entire buildings and work
environments to a standstill, access control cannot be assured – these horror
scenarios can be avoided! Lightning and surge protection precautions ensure that
important technology always works safely and reliably.

Regulations call for protection measures
External lightning protection
The surge protection requirements of the IEC 60364-4-44 clause 443 and
A Air-termination system B Roof conductor holder C Down conductor D Terminal lug IEC 60364-5-53 clause 534 standards mentioned before also apply to office and
for flat roofs commercial buildings. As far as the protection of people is concerned, further build-
ing regulations must be observed, e.g., fire protection regulations. Here, lightning
and surge protection also makes a significant contribution towards preventing people
from sustaining serious injuries and buildings from catching fire.

applies. The focus here is on the safety of patients and medical staff. The standard
