Fire Compartmentation Survey

Fire Compartmentation Survey 

Passive Fire Protection refers to the built-in safety measures designed to slow the spread of fire and smoke without requiring any action or trigger to operate. These systems are always on, quietly embedded into the structure of buildings, vehicles, and industrial equipment.

Passive fire protection is essential for building and managing different structures as part of fire safety. In environments where machinery are often used for long periods, electrical panels stay hot, and combustible materials are never far off. This makes electrical hazards like overloaded circuits or faulty wiring pose a significant ignition risk. In these settings, the real question isn’t if a fire will occur, but when—and when it does, seconds matter. For industries like construction, mining, logistics, and manufacturing, passive fire protection systems are often the first and only line of defense between a manageable incident and a full-blown shutdown.

Implementing passive fire protection methods help do the following:               

·        Contain the blaze at its source

·        Maintain safe evacuation paths

·        Preserve structural integrity during extreme heat

·        Protect critical infrastructure like server rooms or control panels

·        Give emergency responders valuable time to intervene

Across global markets, there are clear frameworks outlining fire-resistant design and maintenance standards. Some of which are the following:

·        NFPA 221 – US standard for High Challenge Fire Walls

• The Factories Act, 1948
• State Fire Safety Regulations (issued by State Fire Services)

·        BS EN 1366 – UK and EU guideline for Fire Resistance Tests for Building Services

·        AS 1530 – Australian methods for Fire Tests on Building Materials

·        ISO 834 – International Standard Fire Resistance Tests

·        The Fire Safety Order 2005 – UK law mandating fire risk assessment and mitigation

Fire Safety Laws in India Mandate Comprehensive Prevention Measures Across Sectors with Strict Compliance Requirements

Yes, compartmentation is a legal requirement in India to prevent the spread of fire, as mandated by the National Building Code (NBC), which specifies adherence to compartmentalization technology in building design for enhanced fire safety. Building codes, such as those found in Part 4 (Fire Safety) of the NBC, require the use of fire-resistant materials and construction techniques to divide buildings into compartments that can contain a fire.

Here are the four principles associated with implementing and ensuring effective passive fire protection:

1.   Containment: Fires grow by finding fuel and oxygen. Containment limits their reach by cutting off those resources using fire-rated barriers that resist penetration.

2.   Compartmentalization: Buildings and facilities are divided into zones, separated by fire-resistant materials. If one compartment catches fire, others remain protected for a designated time (e.g., 60 or 120 minutes).

3.   Structural Fire Resistance: Passive systems protect critical supports like steel beams or cable trays from rapid failure, allowing structures to stay upright longer under intense heat.

4.   Smoke and Toxic Gas Control: Passive fire protection doesn’t just focus on flames, as smoke, especially in enclosed or underground areas, is often the deadliest threat. Seals, dampers, and airtight closures prevent toxic fumes from traveling quickly through buildings.

The objective of fire compartmentation is to prevent the spread of smoke, gases, and flames. By subdividing the building with fire resisting construction, escape routes and high-risk or high-value areas are protected to ensure the safety of occupants and prevent extensive losses. 

Our teams will visually inspect all areas of the identified compartment lines within your building to assess their likely performance in the event of a fire. Defects in compartmentation lines can take numerous forms and require expert identification.

A suitable and sufficient fire risk assessment will typically involve a review of existing fire compartmentation measures through a sampling approach (walls, floors, voids, and shafts predominantly). 

Sampling can indicate the presence of significant issues, such as locating or confirming the presence of fire dampers, or establishing if existing measures meet the requirements of current guidance or other specific business resilience objectives.

Common defects include: simple penetrations, such as pipework entering or exiting a compartment with gaps, or inappropriate firestopping, allowing smoke or fire to potentially pass from one compartment to another. Other defects include: cabling, voids, ducts or linear gaps where compartment lines do not fully encapsulate the compartment. These defects are either latent, from the original build, or imposed from subsequent works (such as M&E events). Both are reiterating the need for regular inspection.

SSA INTEGRATE offer four distinct survey types

Indicative

SSA INTEGRATE will undertake all elements of the "standard" compartmentation survey, but only to selected floors or areas of a building. This will give you the same detail of electronic reporting within your chosen areas, from which our specialists will extrapolate results to enable indicative results to be presented for review.

Standard

Our standard survey is classed as "invasive". This means we will review all areas of the building, along with inspecting some harder to reach areas, such as roof voids, above suspended ceilings, and through inspection hatches in solid ceilings.

Enhanced

This option provides all the benefits of the "standard" survey, but includes additional indicative destructive works, including a percentage of identified areas for further investigation. In most cases, this will include 10% of soil vent pipes and 5% of behind architraves. Our teams will make good on all works, with follow-up attention by your chosen decorator.

Destructive

All elements of the "non-intrusive" survey, together with a pre-defined scope of intrusive works that are defined as a greater requirement than the enhanced survey option. The Fire Compartmentation Inspection Report Electronically recording all deficiencies. along with photographic evidence, the report will highlight the following:

A unique identifying number for each defect

Location

Room type

Required fire rating

Penetrating service type

Seal type required

Date and surveyor details

Due to full Compartmentation Surveys only being required for large, complex buildings, a Compartmentation Sample Survey could be more suitable for your organisation.  

·        Based on a minimum of 10 buildings. 

·        Surveys sample areas of each building (including samples of doors), to provide a general overview of compartment defects that are representative of all buildings.

·        Includes recommended actions.

·        Provides a risk rating for the buildings based on survey findings.

·        Significantly quicker and more cost-effective than a full Compartmentation Survey. 

FAQ:

What is a Fire Compartmentation Survey?  

Fire Compartmentation involves dividing a room, space, or storey of a building into fire-resistant compartments. This is achieved through the implementation and maintenance of fire-resisting floors and walls. Any openings or penetrations in the floors or walls, such as doors, windows, or service penetrations, must be installed and maintained to ensure the wall or floor remains fully sealed. A Compartmentation Survey assesses the condition of these elements of construction in providing fire-resisting compartmentation and identifies any subsequent defects.

When is a Fire Compartmentation Survey needed?  

Currently, there is no legal requirement specifying how often a Fire Compartmentation Survey should be conducted. Compartmentation should be reviewed as part of a regular Fire Risk Assessment (FRA) review process. If issues with compartmentation are raised in the FRA, particularly in hard-to-access areas, then a Compartmentation Survey is crucial to provide a comprehensive assessment. Compartmentation Surveys are also essential when serious defects are identified in either the common parts or inside the flats, as these cannot be accurately investigated during the FRA. 

What does a Fire Compartmentation Survey involve?  

Our Compartmentation Survey options are based on your needs and tailored to each of your buildings. As we don’t undertake remedial works following the Compartmentation Survey, you can be confident that our advice is impartial and reliable to avoid any unnecessary costs.

Fire blankets carried by fire departments

Fire blankets carried by fire departments 

Ensuring the safe evacuation of vulnerable people from supported housing can be a major challenge, but SSA Integrate has implemented some innovative approaches to ensure residents with disabilities can safely escape without the need to rely on ‘stay put’ procedures and fire service assistance. Fire blankets are made of specially treated synthetic and fire-resistant or fire-retardant materials, including woven fibreglass and wool, which can withstand high temperatures of around 500 to even 900 degrees Celsius.

In firefighting, rapid and effective response is paramount. As fire departments continually strive to optimise their equipment and techniques, the inclusion of fire blankets, particularly for car fires, is a compelling consideration. Fire blankets, though often overlooked, offer unique advantages that can significantly enhance fire safety and response efficacy. NFPA 701 sets the standard for fire tests of flame propagation of textiles and films. This standard includes testing procedures for determining the flame resistance of fire blankets.

The Hazards Movement supports people working to ensure equality in safety, public and occupational health for everyone in society, including but also beyond the workplace. Everyone is entitled to feel and be safe and secure from hazards, contaminants and unsafe practices in their life, one of the basic needs identified in Maslow’s hierarchy. The fire safety management system predicated on a fire risk assessment, the findings of which dictate the fire safety management systems implemented, tested, reviewed and rehearsed to ensure everyone’s safety.

The unique nature of car fires

Car fires present distinct challenges compared to structural fires. Vehicles contain a mix of flammable materials, complex electrical systems, and, increasingly, highenergy battery packs in electric and hybrid cars. Traditional methods, primarily using water or foam, can be effective but come with limitations, such as potential electrical hazards and the difficulty in suppressing fires involving modern vehicle components. Fire blankets provide a straightforward, versatile solution to these challenges.

Practical implementation

For fire departments, integrating fire blankets into standard equipment involves training personnel in their effective deployment. Firefighters should be proficient in using blankets to cover burning vehicles swiftly, ensuring complete coverage to maximise oxygen deprivation. Additionally, fire departments can develop protocols for the coordinated use of fire blankets with other firefighting methods, creating a multi-layered approach to vehicle fire suppression.

Fire Blanket Sizes

While the market is filled with a range of fire blanket sizes. The standard sizes of fire blankets variants popular in New Zealand are available in –

·        1.0 m X 1.0 m – Ideal for homes and small kitchens

·        1.2 m X 1.2 m – Ideal for homes and large home kitchens

·        1.2 m X 1.8 m – Ideal for commercial kitchens, clothing fires, and small workplaces with potential fire hazards.

·        1.8 m X 1.8 m – Ideal for commercial kitchens, commercial facilities, and clothing fires. 

Advantages of fire blankets

1. Immediate Containment:

Fire blankets can quickly smother flames, depriving the fire of oxygen and stopping

its spread. This immediate containment is crucial in car fires, where rapid escalation can lead to explosions or the involvement of nearby vehicles and structures

2. Safety:

Using water or foam on electrical components or fuel systems can pose risks. Fire blankets mitigate these hazards by providing a nonconductive barrier, reducing the chance of electrical shocks or chemical reactions.

3. Environmental Impact:

Fire blankets reduce the need for chemical extinguishing agents, which can have adverse environmental effects. This aligns with growing environmental stewardship in fire departments and communities.

4. Reusability and Cost-Effectiveness:

High-quality fire blankets are durable and can be reused after proper decontamination, offering a cost-effective solution over time. This contrasts with the recurrent costs associated with foam and chemical extinguishing agents.

Fire Blanket Maintenance

The fire blankets should be kept in a handy yet safe location where they are not contaminated with fats, cooking oil, or other flammable materials. Fire blankets contaminated with these materials pose the risk of fire hazards and may not effectively stop the fire. 

The extinguishment quality of the fire blanket degrades after use as it is contaminated with unfriendly and flammable materials. This is why the fire blankets should be disposed of after one use and replaced immediately.

Does a Fire Blanket Substitute a Fire Extinguisher?

No, it doesn’t. It is recommended to keep fire extinguishers and fire blankets handy during fire emergencies. Fire blankets are meant to be used alongside fire extinguishers, and one doesn’t overlap the importance of the other.

In fires of higher classes, fire extinguishers are a must. Remember, the fire blankets are only useful to stop small contained fires. It cannot potentially safeguard against larger fires.

Conclusion

As fire departments evolve to meet modern challenges, embracing fire blankets for car fires represents a strategic enhancement of firefighting capabilities. The immediate containment, safety benefits, environmental considerations, and cost-effectiveness of fire blankets make them an invaluable addition to fire response tools.

By equipping firefighters with fire blankets, departments can ensure a more effective, safer, and environmentally friendly approach to combating car fires, ultimately safeguarding lives and property with greater efficacy. Fire emergencies don’t occur with a warning, and it’s wise to stay prepared. It’s a worthy investment in a product you don’t ever hope to use, but if the situation ever demands it – you’ll be glad you made the right choice.

FACTS VS MYTHS PASSIVE FIRE

FACTS VS MYTHS: YOU DIDN'T KNOW ABOUT PASSIVE FIRE PROTECTION 

Fire safety is a paramount concern in the construction and design of buildings, and passive fire protection plays a crucial role in preventing the spread of flames and ensuring the safety of occupants. However, there are various myths surrounding passive fire protection that can cloud our understanding of its effectiveness. Let's debunk these misconceptions and uncover the facts behind passive fire protection.

The National Fire Protection Association (NFPA) has multiple codes related to passive fire protection, including NFPA 80, 90A, 105 & 221. These codes cover the installation, maintenance, and care of fire doors and opening protectives.

The passive fire protection structure has four main areas:

·        Structural Fire Protection.

·        Fire Compartmentalization.

·        Opening Protection.

·        Fire Stopping Materials.

1. Myth: Passive Fire Protection is Only for High-Rise Buildings

Fact: Passive fire protection is essential for buildings of all sizes. While it is often emphasized in high-rises, it is equally important in residential homes, commercial structures, and industrial facilities.

2. Myth: Passive Fire Protection is Expensive and Impractical

Fact: While there is an initial cost associated with implementing passive fire protection measures, the long-term benefits far outweigh the investment. These measures are cost-effective when considering the potential loss of life and property in the absence of adequate protection.

3. Myth: Fire Doors Are Just Like Any Other Doors

Fact: Fire doors are specially designed and rigorously tested to resist the spread of fire and smoke. They are a critical component of passive fire protection, providing crucial time for evacuation and limiting fire damage.

4. Myth: Fire-Resistant Glass Compromises Clarity

Fact: Fire-resistant glass maintains transparency while withstanding high temperatures. It allows for visibility during a fire, aiding both occupants and first responders.

5. Myth: Passive Fire Protection is a One-Time Installation

Fact: Passive fire protection requires regular maintenance and inspection to ensure its effectiveness. Firestops, fire doors, and other measures need to be routinely checked and, if necessary, repaired or replaced.

6. Myth: Concrete Is Immune to Fire Damage

Fact: While concrete is highly fire-resistant, it can still be damaged by extremely high temperatures. However, it significantly contributes to the overall fire resistance of a structure.

7. Myth: Passive Protection is Redundant with Active Systems

Fact: Passive and active fire protection systems are complementary. While active systems like sprinklers react to a fire, passive measures operate continuously, providing a reliable first line of defense.

8. Myth: Only New Buildings Benefit from Passive Fire Protection

Fact: Retrofitting existing structures with passive fire protection measures is common and highly recommended. It enhances the safety of older buildings, bringing them up to contemporary fire safety standards.

9. Myth: Firestops Are Only Necessary in Walls and Floors

Fact: Firestops are crucial in various building elements, including ceilings, ductwork, and electrical penetrations. They prevent the spread of fire through concealed spaces, offering comprehensive protection.

10. Myth: Passive Fire Protection is a Standalone Solution

Fact: Effective fire safety requires a combination of both passive and active measures, along with proper training and evacuation plans. Passive protection sets the stage for active systems to intervene when needed.

11. Myth: I don’t need passive fire protection yet

Fact: We have had several encounters or heard stories wherein a potential client thinks they do not need it yet…until they suddenly do. It’s too unfortunate to know that lives could have been saved, assets could have been protected, and fire hazards could have been easily handled or prevented through an effective fire protection system.

Separating fact from fiction is crucial in understanding the significance of passive fire protection. By debunking these myths, we can appreciate the true value of these measures in safeguarding lives and property during a fire emergency. Implementing and maintaining passive fire protection remains a cornerstone in creating resilient and secure built environments.
