Type of Fire and use fire extinguishers

Every person working in a workshop should have complete knowledge about the fire, such as how the fire is, what type of fire can be extinguished by which device, how to avoid different types of fire.

In this blog, we will tell you how many types of fire are there and with which device they can be extinguished.

How does fire first start? What is the definition of fire?
In the same way, there are many more.
The essential elements for fire are oxygen, heat, fuel. If oxygen heat and fuel is present, then it can be the cause of fire. If any one of the oxygen, heat or fuel is removed from the place where there is a fire, the fire can be controlled easily. Different fire extinguishers are used to extinguish different types of fires.

Fire types and fire extinguishers

Class A
Wood, coal, paper, cloth
Use - Soda Acid Fire Extinguisher

Class B
Oil fire
Use - Foam Fire Extinguisher

Class c
Gas fire
Use - Dry Powder Fire Extinguisher

Class d
Electric fire
Use - C.T.C Fire Extinguisher & CO2

Ways to avoid fire in workshop

1. There should be a suitable location for electronic goods.

2. Electronic goods and all machines should be repaired regularly and if there is any defect.

3. Do not throw a match of burning matches.

4. Flammable and explosive materials should be kept in a safe place so that no accident occurs.

5. Welding etc. should not be done near flammable and explosive materials.

6. Safety should be adopted while working in the workshop.

7. Fire extinguishers should be kept in the workshop and they should be checked periodically. Whether he is fit for work or not.

8. There should be proper arrangement to exhaust flammable and harmful gases generated in the workshop.

9. The power supply system and welding shop in the workshop should be in one place separately so that no accident occurs.

Drilling Machine

Most of the drilling machines are used for hole, using taper shank and parallel shank drill on the drilling machine. The machine used to drill in the metal by drill is called drilling; through it the other operations; Such as drilling, tapping, reaming, counting, counting, boring etc. are also done.

There are two types of drilling machines

1. Portable Drilling Machine

2. Stationary Drilling Machine

1. Portable Drilling Machine

Machines that are easily used by moving from place to place are called portable drilling machines. Portable drilling machines are of the following types

1. Hand Drilling Machine

2. Breast Drilling Machine

3. Ratchet Brace Drilling Machine

4. Electric Portable Drilling Machine

5. Pneumatic Drilling Machine

Marking Media of Different Types

The lines drawn on the metal are not visible properly, for this, a marking media is placed on the job. There are many types of marking media, such as

1. White Wash

2. Pursian Blue

3. Copper Sulphate

4. Layout Media

White Wash - Several types of slices are made to work on white paint on the surface of the job.

• Solution of ordinary black board chalk water.

• Solution of ordinary chalk in Methylated Spirit.

• Solution of white lead powder in turpentine oil.

This is the most commonly used marketing media. It is used for marking on castings or forged surfaces. On drying, white coating on the surfaces sticks. When marking with the Scriber, this coating leaves and the drawn line of the scribbier is clearly visible. This makes the thick surface of the coating, due to which the machine is not suitable for the work. Using the solution made in iron, it becomes rusty. Therefore, slurry made in spirits or turpentine oil should be used. .

Pursian Blue - It is used on machining surfaces. The very thin layer of Persian Blue spreads on the surface of the job, so the markings received by it are very clear and eccentric. But its coating takes much more time to dry.

Blue vitriol - A blue colored solution is found when copper sulphate is dissolved in water. In order to make it more active, some drops of sulfuric acid are added. By applying this solution on the surface of the marking, it turns the surface to the color of the compass. It is used only for steel jobs. Very accurate marking can be done on this. It is used for marking on sophisticated surfaces. Grease, oil etc. should be cleaned from surfaces before applying this coating.

Layout Die - This is a type of faucet ink (commercially available in many colors in the market). Which is easily spread on the metal surface. It gets dry soon. The marking on this is very clean and tidy. The surface should be cleaned before laying out the dye. This marketing media is also used on refined surfaces.

Combination Set

Combination set is used to measure the job's angle, to remove the centre of the round job, it has 4 parts.

1. Blade Rule

2. Square Head

3. Protector Head

4. Centre Head

Blade & Rule

It is made with high carbon steel and alloy steel and on hard temper. A key way is cut in the canter of this rule. With the help of which the three head salads do.

Square Head

This is made of cast steel. If the blade or rule is set in it, it can easily check an angle of 90° and 45° degree. It is also used to check depth to measure. The square head also has a spirit level. With the help of which it can easily check the surface level. And it fits on the scrubber, with the help of which the line can be drawn.

Protector Head

The protector head is made of cast steel in which a disk is located, which has a mark of 0° to 180°  Which is used to check the angle.

Canter Head

The centre head cast is made of steel and the angle between its sides is 90 degrees. With this help, you can easily check any circular job canter

1. Metal of Blade of Combination Set - High carbon steel and alloy steel

2. Angle between the two sides of the square head - 90° and 45°

3. Which part of the compartment set is attached to the scribbler - Square Head

4. Which part of the compartment set is used to remove the centre of the round job - centre head

5. How many degrees are done on the dumps of the composition set - 0° to 180°

6. Which parts of the composition set are used to measure and check the depth of the job - Rule and Square Head

7. Combination set is used - to check the angle

8. The centre head is made in which angle - 90°

Steel rules and scales and their uses

Steel rule is a measuring tool. This is a direct measuring tool. Standard steel rule is made of stainless steel. And Steel rule is also made of spring steel. Most of the use of the steel rule is done to check and measure any job in the workshop. Minimum measurement of 0.5 millimeters by steel rule can be checked. It can be checked by 6 to 48 inches or 15 to 120 centimeters and 150 to 600 millimeters.

1. Standard steel rule is made of stainless steel

5. Most of the rules are used to check the measurement of a job in the workshop.

6. Scale is used to make drawing and Sketch.

7. The folding rule is used in the carpenter shop.

8. The use of steel tape and Canvas lace is used to take large measurements.

9. Depth rule is used to take measurements in more Depth.

10. The caliper rule is used to take the outer and inner measurements.

11. Scales are made of wood or plastic etc.

12. The short rule is taken in a holder and used to measure the width.

13. The inch of the shrink rule is 1/10 to 7/16 inches per foot in the actual inch
