Record the pressures that are displayed on the gauges 27. When shutting down the machinery, there may be pressure in the gauges even if the bottle is off. Why is this? a. The cylinder valve isn't turned off properly b. The cylinder has a leak c. There is still gas pressure in the hoses that needs to be released d. The hoses have a leak 28. What is the name of the tool that is used to light the torch? a. Lighter b. Sparker c. Flint Striker d. Lighting Switch 29. When operating the oxy-fuel machinery, the hoses should be located __ a. In front of you so you can see them at all times b. Behind you to prevent any sparks from melting the hoses c. To the side so that the instructor can ensure they aren't in the way d. Hanging off your shoulder so they are completely out of the way 30. T/F: Acetylene tanks are more dangerous than oxygen tanks.
- 11. The gas flames produce infrared radiation that is harmful to your eyes. What type of glasses/shield/goggles should be worn to prevent your eyes from being burned? a. Any safety glasses b. Sunglasses c. Heat Shield d. Shade 5 or darker glasses/shield 12. What is the purpose of the regulators? a. To regulate the pressure that is being released from the tanks and to the torch b. To regulate the temperature of the gases in the tanks c. To regulate the water concentration of the material that is being cut d. To regulate the size of flame that will be created once lit 13. How is the fuel line threaded? a. Right Hand Thread b. 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? a. 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 c. To have something to hold on too during transportation of the cylinder d. It is solely just for decoration 19. T/F: The oxy-fuel rig is safe to use without regulators in place. 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 out d. Gas leaks are only determined by licensed professionals
