1Which shade of filter lens is recommended as the minimum eye protection for manual metal arc welding (SMAW) operating between 75 and 200 amperes?
A.Shade 10 to 11
B.Shade 4 to 5
C.Shade 7 to 8
D.Shade 14 to 15
Explanation: For manual metal arc welding (SMAW) at currents between 75 and 200 amps, a filter shade of 10 to 11 is recommended to protect the welder's eyes from ultraviolet (UV) and infrared (IR) radiation. Shades 4 to 5 are too light and are meant for gas welding or cutting, while shade 14 to 15 is excessively dark and intended for very high-current carbon arc welding. Using the correct shade prevents 'arc eye' and permanent retinal damage.
2Which safety device is designed to extinguish a flame and stop the reverse flow of gas in oxy-acetylene welding and cutting systems?
A.Flashback arrestor
B.Non-return valve (check valve)
C.Pressure regulator
D.Cylinder manifold
Explanation: A flashback arrestor is a safety device designed to quench a flame and stop reverse gas flow by using a porous metal or sintered element to absorb heat. Check valves or non-return valves only prevent the backflow of gas but cannot extinguish a flame once it has entered the hose. Regulators control the working pressure of the gas, and manifolds combine gas from multiple cylinders.
3How are the cylinder valve connection threads for combustible gases like acetylene and LPG differentiated from non-combustible gas connections?
A.They have left-hand threads with a groove cut into the nut.
B.They have right-hand threads with a smooth nut surface.
C.They are color-coded green with extra-fine threads.
D.They use female quick-release snap couplings only.
Explanation: To prevent accidental cross-connections, fuel gas fittings (such as acetylene and LPG) feature left-hand threads, which are marked by a distinctive V-groove cut into the outer flats of the brass hex nut. Non-fuel gas connections, including oxygen, argon, and carbon dioxide, utilize standard right-hand threads without grooves. This mechanical safety standard is universally applied to avoid mixing flammable and oxidizing gases.
4What is the correct procedure for storing oxygen and acetylene cylinders when they are not in active use in a welding shop?
A.Stored upright, secured with chains, and separated by a fire-resistant wall of at least 1.5 meters high or a distance of 6 meters.
B.Laid horizontally on racks together to prevent them from falling over.
C.Stored in a tightly sealed storage container to keep out dust and moisture.
D.Chained together in a single group to maximize space saving.
Explanation: Oxygen and acetylene cylinders must be stored upright, secured with chains to prevent falling, and separated by a distance of at least 6 meters (20 feet) or by a non-combustible barrier at least 1.5 meters (5 feet) high with a fire-resistance rating of at least 30 minutes. Storing them horizontally is dangerous because liquid acetone can leak from acetylene cylinders. Sealed containers can lead to gas accumulation and explosive atmospheres.
5Which of the following is the most appropriate first-aid response for a minor, closed heat burn on a welder's forearm?
A.Immerse the burned area in cool, clean water for at least 10 to 15 minutes.
B.Apply welding grease or petroleum jelly immediately to soothe the pain.
C.Pop any blisters that form to speed up the skin's healing process.
D.Apply ice directly to the burn to reduce swelling rapidly.
Explanation: A minor closed heat burn should be treated immediately by cooling the skin under clean, cool running water for 10 to 15 minutes. Greases, oils, and butter trap heat in the tissues and can introduce infection. Blisters should never be popped because they act as a sterile barrier, and applying ice directly can cause tissue damage resembling frostbite.
6Why is it critical to wear safety glasses under a welding helmet during welding operations?
A.To protect the eyes from flying slag and spatter when the helmet is flipped up.
B.To double the shade value of the welding helmet's filter lens.
C.To prevent the helmet from sliding off the welder's head.
D.To filter out high-frequency sound waves from the arc.
Explanation: Safety glasses must be worn under a welding helmet because slag, sparks, and debris can still fly behind the shield, especially when the welder flips up the helmet to inspect or chip the weld bead. They provide continuous lateral and frontal physical impact protection. They do not increase the light-reduction shade value, prevent the helmet from slipping, or filter sound waves.
7Which type of fire extinguisher is mandatory to have near a welding station specifically for electrical fires involving energized equipment?
A.Class C (CO2 or dry chemical) extinguisher
B.Class A (pressurized water) extinguisher
C.Class D (special dry powder) extinguisher
D.Soda-acid extinguisher
Explanation: Electrical fires involving energized equipment are classified as Class C (in the US system; Class E in international standards). Carbon dioxide (CO2) or dry chemical extinguishers are non-conductive and safe for these fires. Water-based extinguishers (Class A or soda-acid) conduct electricity and present a severe electrocution hazard to the operator. Class D extinguishers are used only for combustible metal fires.
8What health hazard is caused by inhaling the white fumes generated when welding galvanized steel, and how is it prevented?
A.Zinc fume fever; prevented by local exhaust ventilation and respirator use.
B.Silicosis; prevented by wearing leather aprons and safety boots.
C.Asbestosis; prevented by using water-cooled torches.
D.Carbon monoxide poisoning; prevented by using carbon dioxide shielding gas.
Explanation: Galvanized steel is coated with zinc. Welding it vaporizes the zinc coating, producing zinc oxide fumes which can cause 'zinc fume fever' or 'metal fume fever' (symptoms include chills, fever, nausea, and muscle aches). Prevention requires proper ventilation, source extraction, and wearing a particulate respirator. Silicosis is caused by silica dust, asbestosis by asbestos fibers, and CO poisoning by incomplete combustion.
9What is the primary function of local exhaust ventilation (LEV) systems in a vocational welding workshop?
A.To capture and remove welding fumes and gases at their source before they reach the welder's breathing zone.
B.To cool down the welding workpiece during high-current operations.
C.To provide a clean supply of pure oxygen to support the arc.
D.To blow away shielding gases to speed up weld solidification.
Explanation: Local exhaust ventilation (LEV) utilizes extraction hoods positioned close to the weld pool to capture toxic welding fumes and gases directly at the source, preventing them from mixing with the general workshop air and entering the welder's breathing zone. It is not designed to cool metal, supply oxygen (which would be a fire hazard), or disrupt shielding gases.
10If a fellow student is in contact with an active, live electrical wire in the welding shop, what is the first action you should take?
A.Turn off or isolate the main power source immediately before touching the victim.
B.Grab the victim's arms and pull them away from the wire as fast as possible.
C.Throw cold water over the victim to disrupt the electrical current.
D.Wrap a wet rag around the wire to insulate it from the ground.
Explanation: The absolute first step is to isolate the electrical source (turn off the switchboard breaker or unplug the machine) to ensure the rescuer does not also become energized by contact. Touching the victim while they are still in the live circuit will result in the rescuer being shocked. Water conductive properties would make throw-water extremely dangerous, and a wet rag conducts electricity.
