A worker notices a frayed wire on a welding machine. What is the most appropriate action?
Tape the wire and proceed
Ignore it if the machine still works
Continue working and report it later
Stop using the machine and report it immediately
During a safety inspection, a supervisor finds that PPE is not being worn properly. What should be the first step?
Conduct a refresher training on PPE use
Penalize the workers involved
Cancel all operations for the day
Replace all PPE immediately
A team is setting up a scaffold near a power line. What should they do before proceeding?
Proceed quickly to avoid delays
Wear rubber gloves
Notify the supervisor and assess the risk
Use wooden planks to insulate the scaffold
A worker refuses to perform a task due to unsafe conditions. What should management do?
Investigate the concern and resolve the hazard
Reassign the task to someone else
Fire the worker for insubordination
Ignore the complaint and continue operations
During a fire drill, one employee panics and runs in the wrong direction. What should the safety officer do?
Let them go and focus on others
Shout instructions from a distance
Calmly redirect the employee to the safe route
Cancel the drill immediately
A new employee is unsure how to use a chemical safely. What is the best course of action?
Ask a coworker for advice
Avoid using the chemical altogether
Refer to the Safety Data Sheet (SDS)
Read the label and guess
A machine operator feels dizzy while working in a poorly ventilated area. What should be done first?
Give the operator water
Turn off the machine
Open a window and continue working
Move the operator to fresh air and report the incident
A safety officer observes that workers are not using positioners correctly. What is the best response?
File a report and wait for management action
Ignore it if no accidents occur
Conduct a toolbox meeting to correct the practice
Replace the positioners immediately
Why are fixtures used in welding?
To hold parts in place during welding
To increase machine speed
To decorate the workpiece
To reduce electricity use
A welder sets the machine to incorrect polarity, causing poor weld quality. What should be done?
Adjust the settings and redo the weld
Blame the equipment
Continue welding and fix it later
Ignore the defect if it’s minor
A worker reports a minor injury but refuses medical attention. What should the supervisor do?
Force the worker to see a doctor
Respect the decision and do nothing
Ignore the report since it’s minor
Document the incident and encourage medical evaluation
What is the function of a ground clamp in welding?
To hold the electrode
To complete the electrical circuit
To stabilize the arc
To feed the wire
What attitude is important when setting up welding equipment?
Speed over safety
Avoiding teamwork
Following instructions
Attention to detail
A welder notices inconsistent arc performance during setup. What should be checked first?
The color of the electrode
The grounding and machine connections
The type of filler metal used
The shape of the workpiece
During a group welding project, one student installs a fixture that doesn’t align the workpiece properly. What is the best course of action?
Continue welding and adjust later
Replace the fixture with clamps
Ignore the misalignment if it’s minor
Reposition the fixture for proper alignment
If a welding machine is set to incorrect polarity, what is the most likely result?
The arc will be unstable
The machine will shut down
The weld will be stronger
The electrode will melt faster
What is the first step in setting up a welding machine?
Check machine settings
Paint the workpiece
Conduct a safety inspection
Remove the electrode
A student prepares to weld stringer beads but selects an E7018 electrode. What should the instructor advise?
Proceed with welding as planned
Use E7018 only for overhead welding
Increase amperage to compensate
Switch to E6011 or E6013 for better control
A student sets up a TIG welding machine but forgets to install the gas regulator. What safety issue might arise?
Lack of shielding gas causing contamination
Excessive spatter
Overheating of the electrode
Machine overload
Which setup practice best demonstrates attention to detail and safety awareness?
Wearing PPE only during welding
Aligning jigs before powering the machine
Checking voltage after welding
Using any available fixture regardless of fit
