🧭 PART 1: How to Check Smoke Alarms

A working smoke alarm is your first line of defence. They save lives—but only when they’re maintained correctly.

🔹 Step-by-Step:

Locate the Alarm – Usually in hallways, bedrooms, or kitchens, mounted high.
Test the Alarm – Press the test button; it should beep loudly.
Replace the Battery – At least once a year (typically 9V batteries).
Clean the Alarm – Wipe with a soft cloth monthly and vacuum vents.

✅ Tip: Replace smoke alarms every 10 years. Test them monthly.

🧯 PART 2: How to Use the Right Fire Extinguisher for Each Fire Type

Different fires require different extinguishers. Using the wrong one can make the situation worse.

🔹 Fire Class Breakdown:

Class A – Ordinary combustibles (wood, paper, fabric)
➤ Use Water or Dry Chemical Extinguisher
Class B – Flammable liquids (petrol, grease, oils)
➤ Use Foam, CO₂, or Dry Chemical Extinguisher
Class C – Electrical equipment (power boards, appliances)
➤ Use CO₂ or Dry Chemical Extinguisher
Class D – Combustible metals (magnesium, aluminium)
➤ Use Specialist Class D Extinguisher

✅ Always read the extinguisher label to confirm it matches the fire class.

🔍 PART 3: How to Check Fire Extinguisher Expiry & How to Use It

Even the best extinguisher won’t work if it’s out of pressure or expired.

🔹 Step-by-Step Inspection & Use:

Check the Pressure Gauge – Needle should be in the green.
Inspect the Expiry Date – Found on the inspection tag or base.
Pull the Pin – Unlock the handle mechanism.
Aim and Sweep – Aim at the base of the flames, sweep side-to-side.

✅ Use the PASS method: Pull, Aim, Squeeze, Sweep.

🔧 Extinguishers need servicing every 6–12 months and pressure testing every 5 years (per AS1851).

🔹 How to Use:

Pull the Tabs – Release the blanket from its container.
Protect Hands – Fold edges over your hands.
Cover the Fire – Gently lay over the flames, don’t throw.
Turn Off Heat Source – If safe to do so.
Leave Blanket in Place – Keep it on the fire for at least 15 minutes.
