Welding Safety Test fully solved

1) T F Do not chip welds without some kind of suitable protection over your eyes. True 2) T F It is not safe to arc weld bare handed. True 3) T F You need not warn others in the arc welding area before you start to weld, because they will see the light when you begin. True 4) T F Cool a hot piece of steel or write "hot" on it when you leave it in the shop, so that others will not come in accidental contact with the hot steel. True 5) T F Welding galvanized metal may cause a health problem to you. True 6) T F Leather welding gloves are required on both hands when doing oxy-fuel cutting. True 7) T F Either chain oxygen and acetylene cylinders securely in an upright position, or weld with the cylinders laying down so they cannot be tipped over. True 8) T F Never handle oxyacetylene equipment with oily or greasy hands. True 9) T F Always use pliers to handle hot materials. True 10) T F Never lay a lighted torch down. True 11) T F When connecting hoses and equipment to the oxyacetylene welder after changing tanks, it is a good idea to check for leaks. True 12) T F Under no condition should a person use matches to light a torch. True 13) T F If a cylinder requires a "T" handled wrench to open the valve, be sure to leave the "T" handle wrench in place at all times while welding or cutting. True 14) Making unapproved projects of any type (including but not limited to weapons, toys and any other unapproved items) is against department policy and is ___________ a) unacceptable and will carry disciplinary action b) alright to do only if you want to c) is ok with permission from a friend d) is ok anytime A 15) T F In this shop there are SMAW (Stick), GWAM (MIG), Oxy-fuel, and GTAW (TIG) welders. True 16) Safety glasses are to be worn in the shop... a) Always b) When you feel like it c) When sparks fly d) Only if they are in style A 17) Horseplay in the shop. a) Is ok if both people want to participate b) Is ok for certain individuals c) Is permitted between classes d) Is never acceptable and will not be tolerated D 18) If a piece of equipment is not working properly, or you accidentally broke it... a) Don't tell anyone b) Inform the custodian c) Tell the principal d) Tell Mr. Hargett D 19) T F It is alright to work in the shop while under the influence of prescription, non- prescription or illegal drugs or alcohol. False 20) It is not a good idea to operate electrical equipment including welders when you have wet or sweaty hands because of the risk of________. To help avoid this you should wear gloves. e) Looking foolish f) Backlash g) Heat stroke h) Electrical shock H 21) It is NEVER acceptable to use any listening device (IPOD, MP3, etc) while in the welding lab because: a) The teacher does not like music b) The cord could get caught in moving machine with you attached c) Both B and D d) It is a distraction to you as you can't hear potential danger in the lab C 22) It is a bad idea to have a fuel lighter in your pocket when welding because... a) smoking is illegal b) you might lose your lighter c) it could explode from a welding spark landing on it d) it could vaporize C 23) T F Safety is the most important thing to consider when working with these machines in this or any other shop is... True 24) T F Oxygen Acetylene welding produces heat up to 6300 degrees Fahrenheit, thus can create instant damage to you and should be treated as extremely dangerous. True 25) Maximum pressure that acetylene can be compressed to inside the cylinder is 300 PSI, it can be compressed this much because of the liner inside the bottle that is made up of... a) acetylene b) acetyl alcohol c) acetone d) oxygen C 26) Maximum pressure for acetylene outside the bottle is_________ PSI, because there is no liner to help stabilize it and it can cause an explosion. a) 15 b) 25 c) 10 d) 5 A 27) The most common reasons for tip popping are... a) A dirty tip and putting the tip in the molten puddle b) A new tip and a dirty tip c) Dropping the torch and stepping on it d) A dirty tip and a too big of a tip A 28) What must you do before lighting the torch, after you just put the system together? a) Back out T-screws before opening bottles b) Check for leaks with a lighter or striker c) Hold your breath d) Hold your breath and watch A 29) T F You are trained to shut off the fuel first in oxyacetylene welding. This is important to purge the system with oxygen, blowing the flame out and preventing a flashback into the torch handle. True 30) T F The working gas pressure coming out of the regulator is adjusted with the T- screw on the regulator. True 31) When setting working pressures for welding, oxygen should be at about____ PSI and an acetylene should be set at about ____ PSI. a) Oxygen=15, Acetylene=5 b) Oxygen=10, Acetylene=20 c) Oxygen=15, Acetylene=15 d) wherever, whatever A 32) You open the oxygen cylinder valve how far? a) One full turn b) Not at all c) All the way d) You don't open it c 33) You open the acetylene cylinder valve how far? a) About 1/4 turn b) Half way c) All the way d) You don't open it A 34) Acetylene systems and cylinders are usually red and have____ handed threads. a) left b) right c) front d) back A
