Fire Compartment
The main goal is to prevent the fire spread to unaffected units and protects the means of escape.

Chapter 4 - Maximum Allowable Quantity (MAQ) for Flammable Liquid
*(SPRINKLER PROTECTED LAB)21
Category Hazard Level Occupancy Type MAQ per lab unit (L)
A High Petroleum and Petrochemicals
Up to 800 (2000)*
B Moderate All except healthcare & IHL occupancy
Up to500 (750)*
C Low All Up to250 (500)*
D Minimal All Up to 10L
Higher classification -> Higher MAQ ->More stringent design requirements

Chapter 5 - MAQ Limitation for Liquid & Gas
22
(SPRINKLER PROTECTED LAB)
Laboratory Unit D (minimal fire hazard)Exempted from the requirements of Table 3
Condition for Basement Level1.Basement levels and floors higher
than 24m habitable floor height shall be sprinkler protected
Exemption from MAQ LimitationIf floor level is protected by sprinkler system, the MAQ is allowed to increase to 100% and area of laboratory unit is restricted to 1000m2

Chapter 8 - MAQ for Compressed and Liquefied Gases
Material Class “In use” ExamplesFlammable gas Gaseous 28.3 m3 5 x H2 cylinders (30L)
Liquefied 15 kg 3 x 4.5kg LPG cylinders
Inert gas Gaseous No Limit -
Liquefied No Limit -
Oxidizing gas Gaseous 42.5 m3 7 x O2 cylinders (50L)
Liquefied 68 kg 3 x O2 Dewar cylinders (20L)

Cylinder in UseAn “in use” compressed gas cylinder is defined as one of the following: a) A cylinder delivering gas by means of a connected regulator or
through a manifold b) A reserve cylinder for the cylinder

10.2 Storage- Requirement on storage (facility, storage condition)10.2.3 Fire safety cabinet to comply with SS 532
25
SS 532 Clause 4.2.4 Safety cabinet marking - “NO SMOKING, NO IGNITION SOURCES”- Maximum allowable capacity indicated clearly
SS 532 Clause 4.2.3 Safety cabinet construction
- Acceptable standard; national or international testing laboratory
- Non-combustible material, minimum 30 mins fire rating; however if housed in sprinkler protected building, the fire rating can be reduced to 10 min

10.2.7 Secondary containment - to contain potential leaks and spills - the capacity should be 10% of the total volume of the liquids in the
containment tray, or the volume of the largest container, whichever is greater.
Fire safety cabinet- Shelves designed such that any spills are
directed to the back and bottom of a leak-proof 2” (51mm) bottom sump
Example 18 L + 5 L + 2.5 L = 25.5 L10% of 25.5 L = 2.55 LHowever, tray size (volume) should be Min. 18 L (volume of largest container)

Prevention through Design1. Eliminate hazards during design process2. Substitute / reduce hazardous materials,
processes and equipment3. “Design in” engineering control to
minimize hazard
