1️⃣ துணி வகைக்கு ஏற்ற temperature மட்டும் பயன்படுத்தவும்

රෙදි වර්ගයට අනුව නිවැරදි උෂ්ණත්වය පමණක් භාවිත කරන්න
Use only the correct temperature for each type of fabric
വസ്ത്രത്തിന് അനുയോജ്യമായ താപനില മാത്രം ഉപയോഗിക്കുക

2️⃣ துணிகளை வகை பிரித்து ஒரே நேரத்தில் ironing செய்யவும்

රෙදි වර්ග අනුව වෙන් කර එකවර ironing කරන්න
Separate clothes by type and iron continuously
വസ്ത്രങ്ങൾ തരംതിരിച്ച് ഒരേ സമയം ironing ചെയ്യുക

3️⃣ Thermostat சரியாக வேலை செய்கிறதா உறுதி செய்யவும்

Thermostat හොඳින් ක්‍රියා කරනවාද යන්න තහවුරු කරන්න
Make sure the thermostat is working properly
Thermostat ശരിയായി പ്രവർത്തിക്കുന്നുണ്ടെന്ന് ഉറപ്പാക്കുക

4️⃣ Iron அடிப்பகுதியை சுத்தமாக வைத்திருங்கள்

Iron පතුල පිරිසිදුව තබාගන්න
Keep the iron sole plate clean
Iron-ന്റെ അടിഭാഗം വൃത്തിയായി സൂക്ഷിക്കുക

5️⃣ தேவையில்லாமல் steam பயன்படுத்த வேண்டாம்

අවශ්‍ය නොමැති විට steam භාවිත නොකරන්න
Do not use steam unnecessarily
ആവശ്യമില്ലാതെ steam ഉപയോഗിക്കരുത്

6️⃣ Iron ஐ அடிக்கடி ON / OFF செய்ய வேண்டாம்

Iron නිතර ON / OFF කිරීමෙන් වළකින්න
Avoid frequent switching ON and OFF of the iron
Iron ഇടയ്ക്കിടെ ON / OFF ചെയ്യുന്നത് ഒഴിവാക്കുക

7️⃣ Iron OFF செய்து மீதமுள்ள சூட்டில் கடைசி துணிகளை ironing செய்யவும்

Iron OFF කර ඉතිරි උෂ්ණත්වයෙන් අවසන් රෙදි ironing කරන්න
Switch OFF the iron and use residual heat for last clothes
Iron OFF ചെയ്ത് ശേഷിക്കുന്ന ചൂട് ഉപയോഗിച്ച് അവസാന വസ്ത്രങ്ങൾ ironing ചെയ്യുക

8️⃣ Loose socket அல்லது thin wire பயன்படுத்த வேண்டாம்

Loose socket හෝ පීච්ච වයර් භාවිත නොකරන්න
Do not use loose sockets or thin wires
Loose socket അല്ലെങ്കിൽ thin wire ഉപയോഗിക്കരുത്

9️⃣ சரியான watt iron box தேர்வு செய்யவும்

සුදුසු watt අගයක් ඇති iron box එකක් තෝරන්න
Choose an iron box with the correct wattage
ശരിയായ watt ഉള്ള iron box തിരഞ്ഞെടുക്കുക

🔚 இதன் மூலம் 25–35% வரை மின்சாரம் சேமிக்க முடியும்

මෙම ක්‍රම භාවිතයෙන් විදුලි බලය 25–35% දක්වා ඉතිරි කරගත හැක
By following these methods, you can save 25–35% electricity
ഈ രീതികൾ പാലിച്ചാൽ 25–35

If the cotton insulation is damaged

1. *Stop using the iron*: Unplug it
immediately.
2. *Don't touch*: Avoid touching the
damaged area to prevent electrical
shock.
3. *Get it repaired*: Take it to a
professional electrician or the
manufacturer's service center.
4. *Replace if necessary*: If the damage
is extensive, consider replacing the iron.

Safety first!

Rating of your 13 A Socket Outlet

• Rated current = 13 Amps
• Supply voltage (Sri Lanka) = 230 V AC

Maximum safe power:

P = VxI
230x13 = 2990W
approx 3kW

✅ So a 13 A socket is designed for about 3,000 Watt only

Typical Kitchen Appliances (example)


(W)
(A)

kettle
2000 W
8.7 A

cooker
1000 W
4.35 A


1200 W
5.2 A


800 W
3.5 A
———————————————

Overload Condition (Actual Calculation)

Example:

Kettle + Rice cooker plugged into same 13 A socket

Total Power= 2000 + 1000 = 3000W

I=p/v
Current= 3000/230
= 13.04 A
—————————————————

⚠️ Already exceeds the rated 13 A

Now add phone charger / extension:

3000 + 100 = 3100W

# I=P/v
3100w/230v= 13.5A

❌ Overload confirmed

🔥 Plugging heavy loads causes:
• Wire overheating
• Insulation melting
• Internal sparking
• Fire inside wall socket

Safety Recommendation (For Public Awareness)

heavy appliance = one socket
13 A outlet for ovens, heaters
extension cords in kitchens
terminal connections
RCCB + correct MCB sizing

⚡ Household Electrical Hazards – What Every Woman Should Know! ⚡

Many home accidents happen due to small electrical mistakes.
Please be aware of these common household electrical dangers:

1.Overloaded plug points
2.Damaged or loose wires
3.Electrical appliances near water
4.Old or faulty appliances
5.Open sockets – dangerous for children

👉 A small awareness can save lives.
👉 If unsure, call a qualified electrician.
