Impairment of fire protection systems
Contents
1. 1 Introduction Fire protection systems as for example automatic fire extin guishing systems and automatic fire alarm systems are essential components of fire protection concepts They also provide a high success rate in extinguishing and or detecting fires Multiple examples of losses show that companies with out adequate fixed fire protection in place often suffer a total fire loss with high property damage and business inter ruption claims The efficiency and reliability of fixed fire protection is thus an essential factor to reduce potential fire damage and to maintain the business continuity of a company In order to guarantee this to a maximum extent repair works periodic In order to reduce the risk of fire during the impairment of fire protection systems additional fire prevention measures must be taken An impairment of fire protection systems increases the risk rh servicing and corrective maintenance to the fire protection systems cannot be avoided Important During an impair ment the risk of having a loss increases mainly because of two reasons Firstly the protection systems that are rel evant for the safety are not in operation Secondly servic ing and maintenance include activities that increase the risk of starting a Tire Proactive planning of the impairment plays an important role to ensure that servicing maintenance and repair works are carried out properly as well to restore the fir2.

Gerling Risk Engineering Guideline Hot works and Hot work permit In order to be able to respond at short notice in case of an unforeseen impairment of fire protection systems detailed procedures should be elaborated in advance These are then immediately avallable when ever required If fire alarm and extinguishing systems are a safety relevant element of the building permit and the occupancy permit this permit for use could be restricted in principle by this impairment Additional protective measures defined by the responsible authority e g fire protection service depart ment may have to be taken into account 4 Measures during the impairment The following should be considered during the impairment of fire protection systems Affixing of warning notices in protected areas and on components of the system clearly indicating that the fire protection system is under impairment Fire protection barriers such as fireproof doors and fireproof dampers should be closed during the impairment Hazardous or critical processes representing a fire risk should be discontinued to the maximum extent possible A fire watch should be provided if possible by the fire brigade or a specialist fire protection company with appropriate communication equipment radio links mobile phones in order to ensure that any fire alarm can be reported without any delay If longer interrup tions of the work are unavoidable patr
