Assessment on Safety in Welding

What is the best step to ensure safety when using welding equipment that has not been used for a long time?

• Store the equipment in a cool and dry place

• Check electrical connections and gas leaks first

• Test the equipment outside the workshop first

• Use the equipment only in the morning

How can you ensure that the welding machine's cable connections are safe before using it?

• Pull the cable to ensure it is taut

• Check the cable for any signs of wear or cracks

• Use a longer extension cable

• Wrap the cable with adhesive tape

What is the effect of using a welding mask with a filter that is not suitable for a specific welding process?

• Reduces light in the workshop

• Increases the risk of inhaling toxic gases

• Reduces the risk of sparks

• Provides inadequate protection against UV light

What is the main reason to avoid using fabrics made from synthetic materials while welding?

• Synthetic fabrics are flammable and melt at high temperatures

• Synthetic fabrics are uncomfortable to wear in hot weather

• Synthetic fabrics are difficult to clean from dirt

• Synthetic fabrics tear easily while working

What safety equipment is required when working with flammable gases like acetylene?

• Regular safety goggles

• Gas detector connected to an electrical source

• Standard welding mask

• Acid-resistant gloves

What steps should be taken if a gas leak occurs during the welding process?

• Close all doors and windows to prevent gas from spreading

• Stop all welding operations and ventilate the area well

• Turn on all fans in the workshop

• Store the equipment in a safer place

Why is it important to check the gas flow connection fittings before starting welding work?

• To ensure gas does not escape during welding

• To avoid noise pollution in the workshop

• To reduce gas usage costs

• To prevent welding process failures and related hazards

What is the consequence if a student fails to turn off the gas supply after finishing welding?

• The gas supply will dry up quickly

• High risk of explosion or fire

• The gas supply will become cold and difficult to reuse

• The welding machine will be easily damaged

What type of fire extinguisher is most suitable for fires caused by electric welding?

• Water extinguisher

• CO₂ (carbon dioxide) extinguisher

• Dry chemical powder extinguisher

• Foam extinguisher

Why is it important to store welding electrodes in a dry place and exposed to minimal air?

• To prevent loss of electrode weight

• To avoid rust formation that can affect welding quality

• To facilitate the storage process

• To prevent electrodes from melting
