What is the need for electrical fire safety via electrical audits
A comprehensive electrical safety audit can provide a thorough review of the electrical system. This could identify potential electrical hazards, flaws in the design system, maintenance system, etc. At present electrical safety audits are carried out as per Central Electricity Authority Regulation 2010. Manual audits are performed at specific schedules and perform the job of inspection, testing and periodic tests in a facility. A new form of safety audits is now possible via automation, where devices like Smart DBs / Smart Auditors / Smart Optimizers offer real time audit and protection. These real time audits are now part of the latest guidelines for fire safety in hospitals.
What are the latest guidelines for fire safety in hospitals?
In response to the several electrical fires in hospital and temporary COVID centers across India, the Ministry of Home Affairs has circulated guidelines on 4th May 2021 to all states and UTs for ensuring safety from electrical fires for both temporary and permanent medical facilities.
The circular F. No. VIII-110111/02 (Adv)/2020-DGCD (F) requires the needs for:
- Permanent hospitals should implement the National Building Code of India
- Temporary Covid Hospitals should implement IS 8758
- Hospitals must request Fire Services to deploy Fire Tender at hospital or alternately engage 24×7 a trained fire safety officer.
- Follow the recommendation in annexure of guidelines in addition to the CEA regulations
What are the recommendations in annexure for electrical fire safety in permanent hospitals?
IS732 is the Indian standard for electrical wiring quality and adopted by the National Building Code of India. In reference to IS732 and IS71521 hospitals must perform:
- Periodic verification for medical standards
- Real time protection via Smart DBs / Smart Auditors / Smart Optimizers
How to identify and resolve potential gaps?
Jhaveri Power Labs has developed the JPL Smart Audit Programme to help medical organizations to identify and correct the specific challenges with optimizing for safety, reliability and energy efficiency. The programme will help hospitals to achieve electrical fire safety as per the guidelines issued by the Ministry of Home Affairs for regular and temporary COVID hospitals. A comparative analysis of the JPL Smart Audit with traditional manual audits is discussed in Table below.
