Using the correct type of fire extinguisher is very important for safety and effectiveness. Each type of fire—such as electrical, flammable liquids, or ordinary combustibles—requires a specific extinguisher. For example:

Class A extinguishers are for wood, paper, and cloth fires.

Class B are used for flammable liquids like petrol or oil.

Class C are for electrical fires.

Class D handle metal fires.

Class K are for cooking oil and grease fires.

Using the wrong extinguisher can make the fire worse or cause an electric shock. Always check the label and know your exting

Webbing slings are color-coded to indicate their safe working load (SWL) or capacity. Different colors correspond to different weight limits, allowing for easy identification of the appropriate sling for a given lift. This system is widely used in the lifting industry to ensure safety and efficiency.

Here's a general overview of the color coding system:

Violet: 1-ton (or 1000 kg)

Green: 2-ton (or 2000 kg)

Yellow: 3-ton (or 3000 kg)

Grey: 4-ton (or 4000 kg)

Red: 5-ton (or 5000 kg)

Brown: 6-ton (or 6000 kg)

Blue: 8-ton (or 8000 kg)

Orange: 10-ton and above

It's crucial to always check the manufacturer's specifications and adhere to the safe working load limits for each sling to ensure safe lifting operations. Different manufacturers may have slight variations in their color coding, so it's important to consult the specific sling's label or documentation.
