Questions: 16 · 10 minutes
1. A production machine releases harmful fumes during normal use. Which measure generally controls the exposure most effectively?
Provide respirators without changing the process or ventilation
Rotate employees between the machine and other tasks
Capture the fumes at their source with properly designed local exhaust ventilation
Post warning signs beside the machine
2. What is the main purpose of a Safety Data Sheet for a chemical product?
To document how much of the product each department has purchased
To confirm that the product is harmless when used in small quantities
To communicate hazards, protective measures, handling guidance and emergency information
To replace all workplace training about chemical use
3. A facility operates a fuel-burning boiler. Which option correctly distinguishes an environmental aspect from an environmental impact?
The aspect is degraded air quality, while the impact is boiler operation
The aspect is fuel combustion, while the impact is the resulting change to air quality
The aspect is community concern, while the impact is equipment maintenance
The aspect is the air permit, while the impact is fuel purchasing
4. An employee discovers an extension cord with exposed internal wiring. What is the appropriate response?
Use it only for low-power equipment until a replacement arrives
Cover the damaged area with ordinary tape and continue using it
Place it where fewer employees are likely to notice the damage
Remove it from service and arrange proper replacement or qualified repair
5. How does personal protective equipment generally fit within the hierarchy of controls?
It is usually a last line of defense after more effective controls have been considered
It removes the hazard permanently from the workplace
It is always more reliable than engineering controls
It makes training and safe procedures unnecessary
6. Which measure is a leading EHS indicator rather than a lagging indicator?
The percentage of planned safety inspections completed on time
The number of recordable injuries last quarter
The number of workdays lost after incidents
The volume of material released in past spills
7. A suspended tool falls beside an employee but causes no injury or damage. What is the most useful EHS response?
Take no action because the event caused no measurable loss
Record it only if the employee requests documentation
Report and investigate the near miss so its causes can be corrected
Wait to see whether the same event happens again
8. When prioritizing hazards for corrective action, which combination generally deserves the most urgent attention?
A frequent event that has no credible harmful consequence
A reasonably likely event with potentially severe consequences
A highly visible condition that does not expose anyone
A minor inconvenience reported by the largest department
9. Before repairing a conveyor that could start unexpectedly, what should maintenance personnel do?
Ask a coworker to watch the controls while the repair is performed
Press the normal stop button and begin work immediately
Isolate hazardous energy, apply required locks or tags and verify the isolation before work
Place a warning note on the controls without isolating the energy source
10. Two waste containers have missing labels, and their contents may be chemically incompatible. What is the best action?
Combine the containers to reduce the storage space required
Choose labels based on the containers' color and location
Open both containers and compare their odors
Stop adding waste, isolate the containers and have qualified personnel identify and manage them
11. Workers at a packing station report wrist discomfort from repeated reaching and twisting. Which response most directly addresses the ergonomic hazard?
Ask workers to stretch before starting each shift
Post reminders encouraging better posture
Offer wrist supports while leaving the task unchanged
Redesign the workstation or tools to reduce reach, force and repetition
12. Which preparation is most appropriate before a worker enters a permit-required confined space?
Evaluate the hazards, test and control the atmosphere, authorize entry and provide required rescue capability
Enter briefly first and complete the paperwork afterward
Use a dust mask as the primary precaution for any possible atmospheric hazard
Rely on the entrant's senses to detect a dangerous atmosphere
13. An unidentified liquid is spreading across a workplace aisle. What is the best immediate response for an employee who is not trained in spill response?
Smell the liquid closely to help identify it
Keep others away, alert the appropriate personnel and follow the site spill procedure
Wash it into the nearest drain before it spreads farther
Absorb it with available materials and place everything in ordinary waste
14. You notice a fire that is growing quickly and producing heavy smoke. What should you do?
Search for the source before telling anyone else
Activate the alarm, evacuate according to the emergency plan and contact emergency responders
Attempt to extinguish it even if you lack training or a clear escape route
Open nearby doors and windows to release the smoke
15. Chemicals are transferred outdoors near a storm drain. Which measure most directly helps prevent an environmental release?
Keep absorbent material indoors so it remains clean
Schedule transfers only when rain is not forecast
Rely on the drain to carry a small spill away from the work area
Use suitable secondary containment, inspect the transfer setup and protect the drain
16. A chemical splashes into a worker's eyes. What should happen first?
Begin flushing at the eyewash immediately, following emergency procedures and obtaining medical help
Wait for a supervisor to identify the chemical before taking action
Rub the eyes with a clean cloth to remove the chemical
Use neutralizing chemicals directly in the eyes
