AEROSOL FIRE SUPPRESSION SYSTEM

 AEROSOL FIRE SUPPRESSION SYSTEM

Compact Fast Cost-Effective Fire Protection

NFPA 2010 Based Design Overview

Slide 2 - What is Aerosol System?

Aerosol fire suppression is a condensed solid agent system that: Releases potassium-based aerosol Suppresses fire via chemical chain reaction inhibition Works without oxygen displacement or heavy cooling

Not a gas system. Not water-based.

It's a hybrid chemical suppression technology

Slide 3

How It Works

Fire detected (heat/smoke/manual)

Generator activates (electrical/thermal)

Solid compound converts to aerosol cloud

Aerosol interrupts flame radicals (H., OH)

Result: Rapid flame knockdown in seconds

Slide 4- Design Step 1: Room Volume

Formula:

Volume = L×W×H

Example:

10m x 5m x 2.5 m

Volume = 125 m³

! Common Mistake:

People ignore ceiling height variation → leads to underdesign.

Slide 5

Design Step 2: Agent Quantity

Typical Design Factor:

80-120 g/m³ (depends on manufacturer & hazard)

Assume: 100 g/m³

+ Required Aerosol:

125 x 100 = 12,500 g (12.5 kg)

! Weak Practice:

Using random "per unit coverage"
