How many types of knot are there?
Although there are literally thousands of different knots, the knots illustrated and animated here include the best knots from the four primary knot categories: Loops (make a loop in the rope), Bends (rope to rope knots), Hitches (rope to object knots) and Binding Knots.

Here are some of the most common knots.
Half Hitch. A half hitch is an unsecure knot which is used in conjunction with other types of knots to create secure knots.
Figure-Eight Knot. 
Bowline. 
Reef Knot. 
Rolling Hitch.
Clove Hitch. 
Sheet Bend.
Double Sheet Bend.

What is the strongest type of knot?
The Palomar Knot is the strongest fishing knot in many situations. This knot only has 3 steps making it extremely powerful and very basic.



Fire Triangle 
The fire triangle or combustion triangle is a simple model for understanding the necessary ingredients for most fires. The triangle illustrates the three elements a fire needs to ignite: heat, fuel, and an oxidizing agent (usually oxygen).

The Fire triangle
Oxygen, heat, and fuel are frequently referred to as the "fire triangle." Add in the fourth element, the chemical reaction, and you actually have a fire "tetrahedron." The important thing to remember is: take any of these four things away, and you will not have a fire or the fire will be extinguished.

How does fire triangle work?
The fire triangle is used to show the three elements that when present together can cause a fire to start. These three ingredients are fuel, heat and oxygen, under all circumstances they should be kept apart to avoid a fire starting.

What are the 4 types of fire?
Fire extinguishers
Class A - fires involving solid materials such as wood, paper or textiles.
Class B - fires involving flammable liquids such as petrol, diesel or oils.
Class C - fires involving gases.
Class D - fires involving metals.
Class E - fires involving live electrical apparatus

Why is the fire triangle important?
The Fire Triangle
The sides of the triangle represent the interdependent ingredients needed for fire: heat, fuel and oxygen.

The important thing to remember is: take any of these four things away, and you will not have a fire or the fire will be extinguished.

How do you break the fire triangle?
Breaking the Fire Triangle. Reducing heat on wildfires may be accomplished in two ways: cooling with water, foam, dirt, or scattering the available fuels to reduce the effect of radiant heat. Water or dirt should be directly applied on the fuels being consumed to reduce fuel temperature.
