Fire Safety

Question 1

What is fireproofing?

Answer 1

Fireproofing is the use of fire-resistant materials in a building to prevent structural collapse and allow safe egress of occupants in case of fire.

The fire-resistant ratings of various materials and constructions are established by laboratory tests and usually specified in terms of the time a material or assembly can be expected to withstand exposure to fire.

Question 2

What is compartmentation?

Answer 2

Compartmentation is a type of passive fire protection. It works by dividing your building into fire-resistant compartments, which delay the spread of smoke, flames, and toxic fumes long enough for occupants to evacuate, and emergency service to respond.

iii. The bottom of the openable area is a maximum of 1100mm above the floor.

Question 13

What is the Fire Safety Act 2021?

Answer 13

Is a law that clarifies the scope of the Regulatory Reform Order 2005.

This was introduced to confirm that the FSO applies to specific elements of buildings that contain more than two seperate residential dwellings.

The elements include the structure, external walls (cladding, balconies & windows), and all doors between flats and common parts.

The Fire Safety Act requires responsible persons to ensure that these elements are included in their fire risk assessments.

Question 18

Explain your understanding of the term “travel distance”

Answer 18

The travel distance should be measured from the farthest point in a room to the door leading to a protected stairway or, if there is no protected stairway, to the final exit of the building.

Government guidelines state that, if there is only one escape route, the travel distance should not be more than 18 metres.

Question 19

When is a fire risk assessment a legal requirement?

Answer 19

If your block of flats or business premises normally has over 4 residents at once, then you are legally required for your fire risk assessment to be documented.

Question 20

Explain the difference between passive and active fire safety features and give me an example of each type?

Answer 20

Passive fire protection is a vital component of any fire safety strategy. It is built into the structure of a building to safeguard people’s lives and limit the financial impact of damage to buildings and their contents. An example would me fire resisting construction.

Active fire protection is about detecting, stopping and escaping fire. Examples would be fire alarms and smoke detectors.

Question 21

What is the purpose of the EWS1 form?

Answer 21

The form certifies if the building’s external walls are “safe” or “unsafe”. It’s valid for five years, unless the external walls are significantly changed.

The seller of a property may need to provide an EWS1 form to the buyer and mortgage lender.

Question 33

How do you ensure fire safety in your specifications?

Answer 33

When I prepare specifications, I will refer to the approved document to ensure that I meet the requirements for compartmentation and means of escape as well as methods to put the fire out and early detection.

My designs are then submitted to the BC where a plan check is carried out to ensure that the designs comply with the standards.

Where the design falls short of the building regulations, adjustments are made based on the comments provided.
