Why Must We Have a Fire Risk Assessment?

Legal Requirement:

• The Regulatory Reform (Fire Safety) Order 2005 (FSO).

• The Management of Health and Safety at Work Regulations 1999: Communal Areas

Regulations 1999: & Landlords’ Common Parts.

• The Housing Act 2004: Section 9 - Housing Health & Safety.

Scotland and Northern Ireland have Broadly Similar ….Legislation, to make Premises as Safe, as is Reasonably…… ….Practicable.

Plus Approved Codes of Practice: British Standards BS 9999:2017

BS 9991:2015

Fire Safety Order (FSO) 2005

Applies to Communal Areas + Landlords’ Common Parts

• Places Duty to Carry Out Risk Assessment.

• Commercial Properties.

• Homes of Multiple Occupancy.

• Purpose-Built Blocks of Flats.

• Controls Depend Upon Risk:

- Premises Above a Chippy?

- Premises Above an Estate Agent?

The Housing Act 2004

In a Nutshell:

Any Premises Shall provide a

Safe and Healthy Environment

for Any Potential Occupier.

Customer or Visitor.

The Building Regulations 2010

• Relevant British Fire Safety Standards + Building Regulations (Codes of Practice) Ensure Adequate Fire Safety Provisions are Incorporated into the Design and Construction or Refurbishment of Premises.

• It is Essential to Maintain the Integrity of Compartmentation, particularly when Building Work and Alterations take place. This Must Include Tenants, When Any Changes Affect Means of Escape.

• Building Regulations Approved Document B 2010• Volume 1 Dwelling Houses.

• Volume 2 Buildings Other Than Dwelling Houses.

• BS 9999: 2017• Fire Compartmentation.

• Segregation of High Risk Areas.

• Planning and Protection of Escape Routes.

• Fire Alarms and Smoke Control.

• BS 9991: 2015• Fire Safety in the Design, Management and Use of

Residential Buildings.

Design Standards

When Must We Have a Fire Risk Assessment?

• Shortly After Refurbishment of the Premises.

• Shortly After Occupancy of the Premises (in a month or so).

• If Significant Changes to Occupancy of the Premises:

• Following Significant Ch Use of the Premises.

• Following Significant C Management of the Premises.

• Following Significant C Fabric of the Premises.

• Following Significant Premises Fire Safety Procedures.

• Following Significant Ch Fire Safety Legislation.

• At a Reasonable Frequency Proportionate to Risk Identified:

- High Risk: Re-Assessment After 6 months From Report.

- Medium Risk: Re-Assessment Annually (Assists Review).

- Low Risk: Bi-Annually, No Significant Risk Outstanding.

Objectives of a Fire Risk Assessment?

• To Identify Fire Hazards and those Persons put at Risk from, Normal Business or by Inattentive Fire Safety Management: e.g. Ignition Sources & Combustible Items < 1m Distant.

• To Remove or Reduce Hazardous Risk to .as Low as is RReasonably Practicable and to Control Higher Risk(s).

• To Check Fire Safety Arrangements Against Building Regulations, at the Time of Construction or Refurbishment.

• To Protect the Safety of People on the Premises by:

- Reducing the Likelihood of a Fire Occurring.

- Limiting the Spread and Probable Severity of a Fire.

- Checking an Adequate Fire Detection & Alarm System in Place.

- Assuring a Suitable and Sufficient Clear Means of Escape.

Types of Fire Risk Assessment

• Type 1: Assessment of Common Parts Only: (Non-Destructive).

- Only Covers Communal Areas & Common Parts: ............ …….(Cupboards, Intakes etc.)

Assumption: That No Works Undertaken Since Last FRA:

….- so No Breaches Compartmentation?

- so No Alterations to Fire Doors?

• Type 2: Assessment of Common Parts Only: (Destructive).

- Some Destructive Inspection carried out: (Small Sample Basis).

- Requires Presence of a Contractor: to Open-up Building Fabric …… and Make-Good, After.

- Includes Physical Check on Compartmentation & Sample Voids.

Types of Fire Risk Assessment

• Type 3: Assessment of Common Parts and Dwellings (Non-Destructive).

- Inspection of Communal Areas & Common Parts of a 10% ……….. …..sample or more of Flats or Bedrooms (where and as relevant).

- Considers Means of Escape.

- Considers Compartmentation in Plant Rooms & Roof Voids.

• Type 4: Assessment of Common Parts and Dwellings (Destructive).

- Sample Destructive Inspection is Carried Out: (on 10%).

- Requires Presence of a Contractor To Open-up Building Fabric and ……. …….Make-Good, After.

“Maintained” Means Light is On All The Time - With Battery Back-Up, if Power Fails.

Emergency Lighting

“Non-Maintained” Means Light is Off - With Battery Back-Up, if Power Fails.

Fire Evacuation Strategy

Full Evacuation

Should This Apply to High Rise: > 6 Stories? …(Still Pending Outcome of Grenfell Final Report)

- If No Fire Detection in Communal Areas?

- If Only FD30s Fire Doors On or Onto MoE?

- Requires Designated Fire Assembly Point?

Delayed (Stay-Put) Evacuation

- Requires Adequate Fire Alarm System: All Flats?

- Ideally Linked to an Addressable Fire Panel?

- All Flats Entrances to be Confirmed as FD60s?

- Ideally With a Secondary Emergency Escape?

Means of Escape

• Escape Routes Must Offer a Minimum Width of 800mm, so far as is Reasonably Practicable. Note: Old Buildings Can Have 750mm Doors. Modern Inclusive Access requires 800mm.

• Escape Routes are to provide Unhindered Access and Egress, but also Safe Evacuation of Occupants, in the event of a fire.

• They shall Remain Free from Obstruction.

• They should be Protected, by Sound Fire Compartmentation, Appropriate Fire Doors and Non-Flammable Materials. Walls and Ceilings should be Zero-Rated for Spread of Fire.

• Stairs, Lobbies, Landings, Corridors, Designated as Escape Routes to be kept Clear of Combustible Material, at All Times.
