📘 Form One Chemistry Notes – Fire, Firefighting and Flames: Fire Triangle, Classes of Fire, Fire Extinguishers, Bunsen Burner & Flame Types | NECTA-Aligned Study Guide PDF
Master fire safety and flames the simple, exam-ready way — from the fire triangle and fire classes to the Bunsen burner and luminous vs. non-luminous flames.

Written specifically for Tanzanian Form One students, this Chemistry study guide covers the Fire, Firefighting and Flames topic in clear, structured notes. From the definition of fire and the fire triangle to fire extinguishers, the PASS method, and flame types — every concept is explained with examples drawn from Tanzanian life, including charcoal stoves in Mwanza, bushfires in Tabora, petrol stations in Dar es Salaam, and hurricane lamps in Lindi and Rukwa.

✨ What’s Inside
✅ Fire:

Clear definition of fire and combustion

The Fire Triangle — Heat, Oxygen, Fuel (with definition and examples)

Fuels in Tanzania — Wood, Charcoal, Kerosene, Petrol, Diesel, Natural Gas, Coal

Real Tanzanian Examples: Charcoal stove in Mwanza, Bushfire in Tabora, Gas cooker in Dar es Salaam

✅ Firefighting:

Definition of firefighting and fire extinguisher

Classification of Fires (Classes A, B, C, D, F) — full table with burning materials, appropriate extinguishers, and Tanzanian examples

Fires Caused by Electricity — why water must NEVER be used

Portable Fire Extinguishers — composition and suitability (APW, Dry Chemical, CO₂, Wet Chemical)

PASS Method — Pull, Aim, Squeeze, Sweep (step-by-step table)

Precautions — distance, fire blanket, CO₂ frost burns

Fire Brigade Contacts in Tanzania — Dar es Salaam, Mwanza, Arusha (114 or 112)

Diagrams: Portable fire extinguishers and parts of a flame (inner, middle, outer zones)

✅ Flames:

Definition of flame and factors affecting colour and temperature

Luminous vs. Non-Luminous Flame — full comparison table (colour, oxygen, combustion, soot, heat, light, sound, safety)

How the Bunsen Burner Works — 4-step process

Flame Types Based on Air Hole Position — Closed, Partly open, Fully open

Parts of a Luminous Flame (4 parts) and Parts of a Non-Luminous Flame (3 parts)

Characteristics Comparison Table

Uses of Luminous Flame — lighting, safety flame, tin lamps, hurricane lamps

Uses of Non-Luminous Flame — heating, flame tests (sodium, calcium, potassium, copper), welding, cooking

Burning Back (Striking Back) — what it is and how to correct it

Diagrams: Luminous flame with soot, Non-luminous flame without soot, Bunsen burner labelled parts

✅ Summary — 10 key takeaways

✅ Practice Questions — Section A (Short Answer), Section B (Structured), and Section C (Essay) with 30 questions total
