Welding Safety - Oxygen Acetylene (Gas) Section 2

When lighting the torch what tool is used:

• match
• pocket lighter
• friction lighter
• flint

Welding on a tank that has contained flammable liquid is:

• easy to do
• done sometimes
• never done in this shop
• dependent on your skills

You must report any leaks of cylinders or connections immediately to the:

• custodian
• instructor
• maintenance department
• welder nearest you

Due to the heat from the open flame, point the welding torch:

• down and away from yourself
• away from all flammables
• away from other students
• all options are correct

When oxy-acetylene welding or cutting, the shade lens to be used is a:

• # 1-2
• # 5-6
• # 8-9
• # 11-12

Where are you more likely to have a potential fire hazard when using welding and cutting equipment:

• the gas welding area

• the production set up area

• the arc welding area

• those areas where portable equipment is being used

Cutting or welding should not be done where an open flame could be dangerous. Areas would include:

• in or near rooms containing flammable vapors and liquids
• where flammable liquids are stored or used
• in a room with high lint or flammable dust or exposed loose combustible materials
• all options are correct

What precautions do you take if you have to weld or cut in an area where combustible materials cannot be removed or covered?

• have a fire extinguisher close at hand
• dampen the exposed area with water before welding
• have a fire watch stand by while the welding is being done
• all options are correct

If in doubt about any welding operation what should you do first?

• check with another student
• check reference materials in your notebook
• check with the instructor
• None of the options are correct

If an acetylene cylinder develops a leak and it cannot be closed by tightening the valve and packing unit:

• set the cylinder outside the building away from possible fire, notify supplier immediately
• run away quickly
• use "welder's emergency stop leak"
• check leaks with open flame
