Any safety glasses Sunglasses Heat Shield d) Shade 5 or darker glasses/shield 12. Whatis the purpose of the regulators? To regulate the pressure that is being released from the tanks and to the torch To regulate the temper rature of the gases in the tanks To regulate the water concentration of the material that is being cut A. To regulate the size of flame that will be created once lit 13. Hoyis the fuel line threaded? (B) Right Hand Thread 6. Left Hand Thread 14. How is the oxygen line threaded? (a) Right Hand Thread b. Left Hand Thread 15. When connecting the hoses to the tanks and torch, which of the following applies? a. Ensure that the green hose is connected to the oxygen tank and torch valve and check that the red hose is connected to the acetylene tank and torch valve b. Make sure you connect the hoses to the torch before you connect them to the tanks C. Always flush the hoses with water before reconnecting them to the tanks and torch d. Add extenders to the hoses if you can not reach the area that needs to be cut. 16. Which of the following is NOT a tip that can be used while dealing with oxy-fuel? a. Welding Tip b. Heating Tip C. Gas Tip d.Cutting Tip 17. Which of the following best describes how the tanks should sit and be handled? a. It doesn't necessarily matter as long as the protection cap is placed over the cylinder valve. b.The tanks should always be in the upright position and locked into place with the locking device. C. The tank can be stored on its side as long as the bottle is empty. d. The cylinder can be used as rollers , if you need to transport a heavy item from one side of the shop to another. 18. What is the purpose of the cylinder protection caps? It acts as an extra layer of security or protection so the valve isn't the first point of contact if an issue were to occur. b. To prevent any excess gas from leaking To have something to hold on too during transportation of the cylinder d.It is solely just for decoration 20. What solution can be used to determine if there is a leak in the connections of the oxy-fuel rig a. Oil/Water Mixture b. Soap/Water Mixture C. No mixture is needed, just place your hand over the hose until you feel air blowing d. Gas leaks are only determined by licensed professionals 19. T/F: The oxy-fuel rig is safe to use without regulators in place.

## Step 1<br />The first question is about the type of goggles that should be worn to prevent eye damage from infrared radiation. The correct answer is "Shade 5 or darker glasses/shield". This is because these types of goggles provide the necessary protection against infrared radiation.<br /><br />## Step 2<br />The second question is about the purpose of regulators in an oxy-fuel rig. The correct answer is "To regulate the pressure that is being released from the tanks and to the torch". This is because regulators are used to control the pressure of the gases being released from the tanks.<br /><br />## Step 3<br />The third question is about the direction of the fuel line threading. The correct answer is "Right Hand Thread". This is because fuel lines are typically threaded in the right direction.<br /><br />## Step 4<br />The fourth question is about the direction of the oxygen line threading. The correct answer is "Left Hand Thread". This is because oxygen lines are typically threaded in the left direction.<br /><br />## Step The fifth question is about the correct procedure when connecting hoses to the tanks and torch. The correct answer is "Ensure that the green hose is connected to the oxygen tank and torch valve and check that the red hose is connected to the acetylene tank and torch valve". This is because this is the correct procedure for connecting hoses to an oxy-fuel rig.<br /><br />## Step 6<br />The sixth question is about the types of tips that can be used with oxy-fuel. The correct answer is "Welding Tip". This is because welding tips are not typically used with oxy-fuel.<br /><br />## Step 7<br />The seventh question is about the correct way to handle and store tanks in an oxy-fuel rig. The correct answer is "The tanks should always be in the upright position and locked into place with the locking device". This is because tanks should always be stored upright and securely locked to prevent accidents.<br /><br />## Step 8<br />The eighth question is about the purpose of the cylinder protection caps. The correct answer is "It acts as an extra layer of security or protection so the valve isn't the first point of contact if an issue were to occur". This is because the caps act as an additional layer of security and protection.<br /><br />## Step 9<br />The ninth question is about the solution that can be used to determine if there is a leak in the connections of the oxy-fuel rig. The correct answer is "Soap/Water Mixture". This is because a soap/water mixture can be used to detect gas leaks.<br /><br />## Step 10<br />The tenth question is a true/false question about the safety of using an oxy-fuel rig without regulators. The correct answer is "False". This is because regulators are essential for controlling the pressure of the gases being released from the tanks.
