1What is the recommended filter lens shade number for Shielded Metal Arc Welding (SMAW) when using an arc current of 150 Amperes?

A.Shade 5 to 7

B.Shade 8 to 9

C.Shade 10 to 11

D.Shade 14 to 15

Explanation: For shielded metal arc welding (SMAW) with arc currents between 75 and 250 Amperes, ANSI Z87.1 and AWS safety standards recommend using a shade 10 or 11 filter lens. This level of shading blocks harmful ultraviolet (UV) and infrared (IR) radiation to prevent optical damage like welder's flash (photokeratitis). Shades lower than 10 do not provide sufficient protection, while shade 14 or 15 is generally reserved for very high current carbon arc cutting or heavy welding.

2Welding in the presence of chlorinated degreasing solvent vapors (such as trichloroethylene) presents a severe hazard due to the potential formation of which toxic gas?

A.Phosgene gas

B.Carbon monoxide

C.Ozone

D.Hydrogen sulfide

Explanation: Chlorinated hydrocarbon solvents decompose rapidly when exposed to ultraviolet radiation from the welding arc or high heat, generating phosgene gas (COCl2), which is highly toxic even in extremely low concentrations. Exposure to phosgene can cause severe pulmonary edema, eye irritation, and can be fatal. Welders must ensure all degreasing solvents are completely removed and vapors ventilated far away from any active arc area.

3Why must acetylene cylinders always be stored and operated in an upright (vertical) position?

A.To prevent liquid acetone from escaping with the gas and damaging equipment

B.To keep the cylinder safety cap from coming loose during pressure releases

C.To allow the cylinder porous filler material to settle evenly at the bottom

D.To maintain a higher gas pressure within the cylinder neck space

Explanation: Acetylene is unstable at pressures above 15 psi (1 bar) in gas form, so it is dissolved in liquid acetone within a porous filler inside the cylinder. If an acetylene cylinder is placed on its side, the liquid acetone can flow out with the gas, clogging regulators, damaging hoses, and creating an extreme fire and explosion hazard. Storing cylinders upright ensures that only gaseous acetylene is drawn from the valve.

4What is the only safe and approved method for testing oxy-fuel gas hoses and connections for leaks?

A.Holding a lit match or lighter near the joints to check for a flame

B.Applying a specialized oil-free soap and water solution and watching for bubbles

C.Listening closely for hissing sounds while spraying WD-40 onto the fittings

D.Submerging the entire hose assembly in a tank of mineral oil under pressure

Explanation: Testing for gas leaks must always be performed using a non-fatty, oil-free soapy water solution or a dedicated commercial leak-detection fluid. Fat or oil-based soaps can react violently with oxygen, which can cause spontaneous combustion or explosion. Hissing sounds are unreliable for small leaks, and using open flames is an extremely dangerous practice that can ignite escaping fuel gas instantly.

5According to standard hot work permit regulations, what is the minimum radius of the spark-containment zone that must be cleared of combustibles before welding?

A.10 feet (3 meters)

B.20 feet (6 meters)

C.35 feet (11 meters)

D.75 feet (23 meters)

Explanation: NFPA 51B and OSHA regulations require a minimum 35-foot (11-meter) radius clearance zone around any hot work activity. Any combustible materials within this zone must be removed, covered with fire-resistant blankets, or shielded to prevent sparks and slag from starting a fire. If combustibles cannot be protected, a dedicated fire watch must be stationed to monitor the area.

6Which of the following electrical terms refers to the voltage present between the electrode holder and the work lead when the welding machine is turned on but no arc is struck?

A.Arc voltage

B.Open circuit voltage (OCV)

C.Operating voltage

D.Secondary circuit drop

Explanation: Open circuit voltage (OCV) is the voltage at the output terminals of a welding power source when it is energized but the arc is not established. OCV is typically between 50 and 80 volts for manual welding machines to help initiate the arc easily. Because the welder is handling the electrode and holder, OCV represents the highest shock risk period during setup and electrode changes, especially in wet or humid conditions.

7Why is wearing synthetic clothing (such as polyester or nylon) strictly prohibited while performing welding operations?

A.Synthetics generate static electricity that can interfere with high-frequency arc starters

B.Synthetics melt when exposed to hot slag and sparks, causing severe skin burns

C.Synthetic fibers degrade rapidly when exposed to shielding gases like helium

D.Synthetic materials block heat release, leading to rapid heat exhaustion of the welder

Explanation: Synthetic fibers like polyester, nylon, and acrylic melt when hit by hot welding sparks or slag. The molten plastic adheres tightly to the skin, causing deep, painful third-degree burns. Welders must wear flame-resistant cotton, wool, or leather, which char instead of melting and provide a physical barrier to thermal energy.

8When performing welding operations inside a confined space, where should the gas cylinders and welding power sources be located?

A.Inside the confined space, close to the welder for quick emergency shutdown

B.Outside the confined space, with lines routed inside and monitored by an attendant

C.Suspended above the confined space entrance to prevent gas build-ups

D.In a separate ventilated storage room at least 50 meters away from the area

Explanation: To prevent gas accumulation (which can lead to asphyxiation or explosions) and to minimize electrical hazards, all gas cylinders and welding power machines must remain outside the confined space. Only the torch/electrode holder, gas hoses, and welding cables should enter the space. A safety standby person (attendant) must be stationed outside to monitor the welder and shut down equipment in an emergency.

9What is the primary objective of using local exhaust ventilation (LEV) systems at the source of a welding operation?

A.To cool down the weld metal rapidly to prevent thermal distortion

B.To pull welding fumes and gases away from the welder's breathing zone

C.To supply fresh oxygen to the welding arc to stabilize the plasma column

D.To dilute the concentration of shielding gas so it does not displace oxygen in the room

Explanation: Local exhaust ventilation (LEV) uses a moveable suction hood positioned close to the weld arc to capture fumes, metal dusts, and gases right at their point of generation. This prevents these contaminants from rising into the welder's breathing zone or spreading throughout the workspace. LEV is the most effective engineering control for minimizing long-term health risks like metal fume fever and lung damage.

10Which of the following practices is correct and safe when moving high-pressure gas cylinders in a workshop?

A.Rolling the cylinders horizontally along the floor using foot pressure

B.Lifting cylinders by their protective valve caps using a crane magnet

C.Securing the safety cap and moving the cylinders in an approved wheeled cart

D.Dragging the cylinders by their valves to avoid lifting hazards

Explanation: Before moving any compressed gas cylinder, the valve must be closed and the safety cap must be securely threaded on to protect the valve stem from breaking off if dropped. Cylinders must always be transported in an upright position secured in a wheeled hand truck or cylinder cart. Dropping or mismanaging cylinders can cause them to rupture and act like a rocket due to high internal pressures.
