Protection impairments occur when a fire prevention, protection, alarm or supervisory system is shut off, impaired or otherwise taken out of service completely or in part. Such circumstances are sometimes unavoidable due to a number of reasons such as a fault, failure or accidental damage of equipment, renovation or expansion of the areas being protected. As a result of these system(s) being impaired, the premises or equipment previously protected are now exposed to a greater loss should an incident occur. Proper impairment handling procedures can assist Management in reducing the impact of such impairments to property and life safety.
INSTRUCTIONS: When fire protection systems (e.g. sprinkler systems, fire detection systems, special - extinguishing systems) or security systems are impaired as follows:
• Impairment/isolation exceeds 8 hours duration or extends overnight, and/or
• Impairment/isolation of any primary fire water supply (city water mains and fire pumps), and/or
• Impairment/isolation affecting more than 25% of the complex/building
