PASSIVE FIRE PROTECTION DIVISION

STRUCTURAL & ELECTRICAL PASSIVE FIRE PROTECTION SERVICES. FIREPROOFING SYSTEMS SUCH AS COATINGS, JACKETS & BLANKETS WHICH DO NOT NEED MECHANICAL ACTIVATION – TO PROTECT STRUCTURES UNDER FIRE
OUR FIREPROOFING TECHNIQUES OFFERED INCLUDES CEMENTITIOUS SPRAY AND / OR TROWEL, CEMENT SYSTEMS, FIRE PROTECTION COATINGS, CLADDING FOR DUCTING AND FIREPROOFING TO STRUCTURES, VESSELS & PIPEWORK.
OUR SERVICES COME WITH CERTIFIED CHARTEK & PYROCRETE APPLICATIONS. UNDER A NORMAL INSTALLATION, THE FINISHED APPLICATION RESULTS IN TWO-HOURS OF FIRE RESISTANCE
MAINTAIN STRUCTURAL INTEGRITY OF METAL SUPPORTS BEFORE COLLAPSE. STEEL STRUCTURE COLLAPSE WITHIN 5 MINUTES IN HYDROCARBON FIRE.

- HYDROCARBON FIRE 200KW/M²
- JET FIRE 300KW/M²
TEST CRITERIA
- STABILITY- THE CONSTRUCTION MUST REMAIN STABLE DURING THE PERIOD OF THE FIRE AND MUST NOT COLLAPSE.
- INTEGRITY- THE CONSTRUCTION MUST MAINTAIN ITS INTEGRITY DURING THE TEST PERIOD SUCH THAT NO GAPS OF SUFFICIENT WIDTH OPEN UP TO ALLOW PENETRATION OF FLAMES.
- INSULATION- THE FIRE INSULATION PROPERTIES OF THE CONSTRUCTION MUST BE SUCH THAT UNEXPOSED FACE MUST NOT INCREASE IN TEMPERATURE BY MORE THAN AN AVERAGE OF 140°C OR BY MORE THAN 180°C AT ANY ONE POINT FOR THE DURATION OF THE TEST I.E 2 HOURS.
PASSIVE FIRE PROTECTION RATINGS
- STRUCTURAL INTEGRITY (LOAD BEARING) –
  - “A” RATING (CELLULOSIC) = 60 MINUTES.
  - “H” RATING (HYDROCARBON) = 120 MINUTES.
- NON-LOAD BEARING –
  - “B” RATING FROM 15 MINUTES .
- INSULATION –
  - “A0” (CELLULOSIC) = 60 MINUTES FIRE PROTECTION + NO INSULATION REQUIRED-NO LIMIT ON BACK FACE.
  - “A60” (CELLULOSIC) = 60 MINUTES FIRE PROTECTION + 60 MINUTES INSULATION-BACK FACE LIMIT REQUIRED.
  - “H0” (HYDROCARBON) = 120 MINUTES FIRE PROTECTION + NO INSULATION REQUIRED.
  - “H60” (HYDROCARBON) = 120 MINUTES FIRE PROTECTION + 60 MINUTES INSULATION.
  - “H120” (HYDROCARBON) = 120 MINUTES FIRE PROTECTION + 120 MINUTES INSULATION.
