E-6 FIRE PROTECTION (Changes in upcoming NBC 2025)

E-7 FIRE AND LIFE SAFETY AUDIT (Changes in upcoming NBC 2025)

E-8 HELIPAD (No Changes in upcoming NBC 2025)

The purpose of the Fire and Life Safety audit is to reduce injury, loss of life, and property damage by developing the area of fire prevention and life safety via leadership and vision for fire safety professionals. Fire and life safety audit is concerned with protecting the occupants of a building from any associated fire and life safety risk by taking life safety precautions.

The objectives of Fire & Life Safety Audit can be focused on the following:

·        Review of Fire safety policy statement (Fire order)

·        Identify all significant fire hazards

·        Identify the people who are at risk from each hazard

·        Evaluate the existing control measures

·        Determine the additional control measures required

·        Examine the availability of a suitable emergency plan detailing the responsibility and action of key personnel

·        Review the availability of a suitable fire alarm and detection system

·        Review the availability of suitable fire fighting facilities, such as hydrants, sprinklers, extinguishers, etc.

·        Evaluate passive fire protection systems provided

·        Evaluate the general awareness of occupants and security personnel on matters relating to fire safety and rescue operations

·        Evaluate the training and instructions on fire safety imparted to the employees and occupants

·        Verifying the records of training imparted to employees and occupants with regards to fire safety

·        Assessing all relevant electrical safety risks

·        Examining the storage and control of flammable and hazardous substances

·        Assessing the existing fire preventive and protective control measures, On-site emergency response plans and fire risk assessment report

·        Testing of all fire safety equipment and systems (Optional).

Case Study 1: AMRI Hospital Fire, Kolkata (2011)

On December 9, 2011, a massive fire broke out at AMRI Hospital in Kolkata, originating in the basement where flammable materials like diesel and medical supplies were stored. The fire spread rapidly, filling the building with toxic smoke, and tragically claimed 90 lives, mostly patients and staff who were unable to escape due to blocked exits and non-functional fire alarms.

Summary of NBC 2016 Part 4 Fire and Life Safety

Summary of NBC 2016 Part 4 Fire and Life Safety 

Bureau of Indian Standards (BIS) is the National Standards Body of India established under the BIS Act 2016 for development of standards, marking and quality certification of goods and for matters connected therewith or incidental thereto.

The National Building Code of India 2016 (NBC 2016), a comprehensive building Code prepared by BIS, is a national instrument providing guidelines for regulating the building construction activities across the country.

Thus, the Code gives all the information required by the architect, engineer, structural engineer, construction engineer, services engineer and other professionals from the early stages of planning to translating the building on to terra firma. The comprehensive NBC 2016 contains 13 Parts some of which are divided into Sections and Subsections totalling 33 chapters.

Key Content - Fire and Life Safety

All buildings shall satisfy minimum requirements for safety of life from fire, smoke, fumes or panic arising from these or similar causes.

Classification of buildings based on occupancy

The city or area under the jurisdiction of the Authority shall be demarcated into distinct fire zones depending upon the existing layout, types of building construction, classification of existing buildings based on occupancy and expected future development of the city or area. Intermixing of hazardous occupancies should not be allowed in other zones.

1) Fire resistant walls, floors and compartments

• To limit the spread of fire

• No compromise for openings such as shafts, refuse chutes, vertical openings, etc.

2) Shafts

• To be provided with fire resistant rated inspection door for passage of building

services such as cables, electrical wires, telephone cables, plumbing pipes, etc

depending upon location.

3) Refuge area

• An area within the building for a temporary use during egress. It generally serves as

a staging area which is protected from the effect of fire and smoke.

4) Fire detection and firefighting installations

• These include fire alarm, fire extinguishers, hose reels, wet riser, down comer,

yard hydrants, sprinklers, deluge system, water spray, foam, water mist systems,

gaseous or dry powder system, water storage tanks and pumps, etc.

5) Means of egress

• Consists of three separate and distinct parts, that is, exit access, exit and exit discharge

• Exit access are working/functional areas

• Various types of exit access and exits are doorways, corridors and passageways, horizontal exits, internal staircases, exit passageways, external staircases and ramps.

6) Firefighting shafts

• With fire man talk back, fire door, wet riser, hose reel, signage showing floor plan and stairways and fire man’s lift
