Fire Resistance Inspection

In accordance with EN 1991-1-2 (fire actions), EN 1992-1-2 (concrete), EN 1993-1-2 (steel), EN 1995-1-2 (timber) and NTC 2018 (Chapter 3.6), structural elements must guarantee fire resistance (R) for the required duration. DM 3 August 2015 (Fire Prevention Code, Chapter S.2) and DM 16/02/2007 define fire resistance classes (R 30, R 60, R 90, R 120) based on intended use and specific fire load.

1. Verify the required fire resistance class from the fire design (SCIA or fire brigade-approved design)

2. For concrete structures, check minimum cover against EN 1992-1-2 requirements and DM 16/02/2007 tables

3. For steel structures, verify thickness and correct application of protective coatings (intumescent plaster, calcium silicate boards, intumescent paints) against test certificates

4. For timber structures, verify section dimensions and allowable charring per EN 1995-1-2

5. Check certificates of protective products and CE marking compliance (EN 13381)

6. Verify continuity of protection at joints, connections and service penetrations

- Concrete cover insufficient for the required fire resistance class

- Protective coating thickness on steel below certified values

- Non-uniform application of intumescent paint with unprotected areas

- Protection interrupted at connections and service penetrations

- Incomplete or missing fire documentation (SCIA, fire resistance certificates)

In accordance with DM 3 August 2015 (Chapter S.3) and EN 13501-2 (fire resistance classification), EN 1366 (service penetration tests), compartmentation must ensure containment of fire and smoke. Closures and service penetration seals through compartment elements must maintain the required REI performance.

1. Verify that compartment walls and floors are built in accordance with the approved fire design, with the required REI performance

2. Check that all service penetrations (pipes, cables, ducts) are sealed with certified systems (EN 1366-3) matching the REI class of the penetrated element

3. Verify that fire doors are correctly installed, with conformity certificate and CE marking (EN 16034, EN 14351-1), functioning door closer and intact intumescent seals

4. Check compartmentation continuity at structural joints, suspended ceilings and raised floors

5. Verify sealing of linear joints with certified systems (EN 1366-4)

6. Check for unauthorised or unsealed openings in compartment walls and floors

- Service penetrations unsealed or sealed with uncertified materials

- Fire doors propped open without magnetic hold-open devices

- Compartmentation discontinuity at suspended ceilings or service shafts

- Linear joints unsealed between compartment walls and floors

- Subsequent modifications to compartmentation without fire design update

In accordance with DM 3 August 2015 (Chapter S.4 - Evacuation) and applicable vertical technical standards, escape routes must ensure safe evacuation of occupants in the event of fire. Emergency exits, escape paths and signage must comply with the approved fire design. Safety signage must comply with D.Lgs. 81/2008 and UNI EN ISO 7010.

1. Verify that the number and width of emergency exits comply with the fire design and DM 3 August 2015 Chapter S.4

2. Check that escape routes are clear of obstacles, with minimum width maintained and non-slip flooring

3. Verify maximum escape route length (distance to emergency exit) per Fire Prevention Code requirements

4. Check correct operation of panic bars (EN 1125) and push-to-open devices (EN 179) on emergency exit doors

5. Verify safety signage (exit signs, emergency lighting) per UNI EN ISO 7010 and UNI EN 1838

6. Check emergency lighting operation along escape routes (minimum autonomy, illumination level per UNI EN 1838)

- Escape routes obstructed by materials, furnishings or equipment

- Emergency doors locked or with non-functioning panic devices

- Emergency signage missing, damaged or non-compliant

- Emergency lighting insufficient or non-functional

- Escape route lengths exceeding limits set by the fire design
