What is the primary mode of transmission for COVID-19 in the workplace?
Airborne via dust particles
Respiratory droplets from coughs or sneezes
Food contamination
Waterborne contamination
COVID-19 spreads mainly through respiratory droplets generated when an infected person coughs, sneezes, or speaks. These droplets can travel short distances and enter the nose, mouth, or eyes of nearby individuals.
What is the recommended minimum distance for social distancing to reduce COVID-19 transmission?
3 feet (0.9 meters)
10 feet (3 meters)
2 feet (0.6 meters)
6 feet (1.8 meters)
Social distancing of at least 6 feet reduces the chance of inhaling infectious droplets by increasing space between individuals. This guideline is based on how far respiratory droplets typically travel before settling.
How long should you wash your hands with soap and water to effectively kill the virus?
10 seconds
20 seconds
5 seconds
60 seconds
Washing hands for at least 20 seconds ensures that soap breaks down the virus membrane and removes pathogens. Shorter durations are less effective at removing or inactivating viral particles.
What is the correct way to wear a surgical mask?
Mask below the nose covering only the mouth
Mask covering both nose and mouth snugly
Mask under the chin above a T-shirt
Mask hanging from one ear
A surgical mask must cover both the nose and mouth to block respiratory droplets effectively. Gaps or uncovered areas reduce its protective function.
Which of the following is a common symptom of COVID-19 that employees should monitor?
Headache only
Joint pain only
Loss of smell or taste
Itchy eyes only
Loss of smell or taste is a distinctive symptom associated with COVID-19 infections and should prompt employees to report and isolate. Monitoring for this symptom helps identify potential cases early.
Which workplace scenario poses the highest risk for COVID-19 transmission?
Crowded break room with poor ventilation
Open outdoor area with distancing
Private office with one person
Virtual meeting
A crowded break room with poor ventilation allows respiratory droplets to accumulate and spread among employees. This environment lacks airflow and successful distancing, increasing transmission risk.
How often should disposable gloves be changed when used during routine cleaning tasks?
After lunch break
When visibly torn only
Once per day
After each task or when soiled
Gloves should be changed after each cleaning task or immediately if they become soiled or damaged to prevent cross-contamination. Continuous glove use across tasks can transfer pathogens between surfaces.
What is the correct sequence for donning personal protective equipment (PPE)?
Goggles, gloves, mask, gown
Gloves, gown, mask, goggles
Mask, goggles, gown, gloves
Gown, mask, goggles, gloves
The correct donning sequence is gown first, then mask or respirator, followed by goggles or face shield, and finally gloves. This order prevents contamination of inner layers and ensures proper seal of higher-level protection.
If an employee tests positive for COVID-19 but remains asymptomatic, what is the recommended action?
Only work in a separate office
Return once a negative rapid test appears
Self-isolate according to guidelines
Continue working with a mask
Asymptomatic individuals who test positive must self-isolate for the recommended duration to prevent spreading the virus unknowingly. Continuing to work, even with a mask, risks infecting others.
Which cleaning agent is most effective against SARS-CoV-2 on surfaces?
Low-concentration soap water
Vinegar
Alcohol solution with at least 70% alcohol
Plain water
Alcohol solutions with at least 70% alcohol effectively inactivate SARS-CoV-2 by disrupting its lipid envelope. Lower concentrations or vinegar are not reliably proven to kill the virus.
When should face shields be used in addition to masks?
To replace gloves
During aerosol-generating procedures
For aesthetic purposes
When masks are unavailable
Face shields offer eye protection and additional barrier during aerosol-generating activities such as intubation or certain cleaning tasks. They complement masks but do not replace them.
What is the minimum recommended air exchange rate in indoor environments to reduce COVID-19 spread?
1 air change per hour
12 air changes per day
2 air changes per hour
6 air changes per hour
Increasing air changes per hour to at least six dilutes airborne viral particles and lowers infection risk. Lower exchange rates can allow pathogens to accumulate in the air.
What is the primary reason for employees to report COVID-19 symptoms immediately?
To schedule vacation
To receive hazard pay
To prevent workplace outbreaks
To get medication faster
Prompt symptom reporting enables timely isolation and contact tracing, reducing the likelihood of an outbreak. Early identification protects coworkers and maintains a safe workplace.
How long can SARS-CoV-2 remain viable on plastic surfaces under typical indoor conditions?
24 hours
7 days
72 hours
5 hours
Studies show the virus can remain viable on plastic surfaces for up to 72 hours under typical indoor conditions. Regular disinfection is necessary to remove contamination and reduce risk.
Which practice best complements hand washing in preventing fomite transmission?
Wearing the same gloves all day
Using hand sanitizer with at least 60% alcohol
Drying hands on clothes
Rinsing hands with water only
Hand sanitizer with at least 60% alcohol is effective at killing SARS-CoV-2 on hands when soap and water are unavailable. It complements hand washing but should not replace it entirely.
In a conference room with limited ventilation, which combination of controls most effectively reduces aerosol transmission?
Turning off the ventilation system
Opening windows only
Relying on social distancing alone
Using HEPA air purifier and consistent mask use
Combining HEPA filtration with consistent mask use addresses both source control and airborne particle removal. Opening windows alone may not provide sufficient filtration in confined spaces.
Which step is essential when disinfecting shared electronic equipment to prevent damage while eliminating SARS-CoV-2?
Applying undiluted bleach directly
Powering off device and using alcohol-based wipes
Wiping with a dry cloth only
Spraying water liberally
Powering off electronics and using alcohol-based wipes or 70% isopropanol prevents liquid ingress and inactivates the virus effectively. Bleach can corrode sensitive components and water alone is insufficient.
An employee with mild symptoms tests negative by a rapid antigen test but still feels unwell. What is the next best step?
Ignore symptoms and monitor
Take a PCR test and continue isolating until results
Return to work immediately
Work from the office wearing a mask
PCR tests have higher sensitivity and can detect infections missed by antigen tests. Continuing isolation until confirmatory results prevents possible workplace transmission.
Estimate the percentage reduction in transmission risk when combining proper mask use with 6-foot distancing versus distancing alone.
30% reduction
75% reduction
10% reduction
No reduction
Studies indicate that combining mask use with distancing can cut transmission risk by around 75%. Each measure contributes additive protection, significantly lowering overall risk.
For aerosol-generating procedures in a clinical setting, which respirator provides the appropriate protection?
Cloth mask
Surgical mask
N95 respirator
Paper mask
N95 respirators filter at least 95% of airborne particles, including aerosols generated during high-risk procedures. Surgical and cloth masks do not offer reliable aerosol protection.

Cheat Sheet

  1. Understand COVID-19 Transmission in the Workplace - COVID-19 sneaks around as respiratory droplets whenever someone talks, coughs, or sneezes. When you share offices or conference rooms, those droplets can make unwelcome pit stops on surfaces and in the air around you. Keeping hands squeaky-clean and respecting personal space are your superhero moves against this invisible foe. OSHA: COVID-19 Hazards
  2. Proper Use of Personal Protective Equipment (PPE) - Gearing up with masks, gloves, and eye protection only works if you know how to put them on and take them off without turning them into contamination tools! Employers should train everyone on the right sequence - donning and doffing like a pro keeps you safe. Practice makes perfect, so treat every PPE change like a mini-fire drill. OSHA: PPE & Control Measures
  3. Implement Effective Social Distancing - Giving at least one meter (about 3 feet) of personal bubble space can seem odd at first, but it drastically cuts down the chance of droplet delivery. Rearrange desks, mark floors, or schedule staggered breaks to keep everyone far enough apart for safety. Think of it as a creative puzzle that keeps health levels high. WHO: Workplace Q&A
  4. Adopt Rigorous Hygiene Practices - Handwashing with soap and water for at least 20 seconds is like hitting the reset button on your hands' clean status. When sinks are scarce, a hand sanitizer with at least 60% alcohol swoops in to save the day. Stock up stations, add fun signage, and remind your team that every scrub is a step toward victory. OSHA: Hygiene & Prevention
  5. Recognize and Report COVID-19 Symptoms - Fever, cough, or shortness of breath aren't just badges of a hard day - they could be red flags for COVID-19. Encourage your crew to speak up at the first sign of feeling off and stay home to protect teammates. Early reporting is your best weapon to stop an outbreak in its tracks. OSHA: Symptom Reporting
  6. Develop Response Procedures for Potential Infections - Have a clear playbook for what happens if someone falls ill on the job: isolation rooms, notification protocols, and cleaning checklists. Clear communication ensures nobody's left wondering "What now?" during a stressful moment. Practice drills so the plan rolls out smoothly when it really counts. OSHA: Response Protocols
  7. Conduct Regular Workplace Risk Assessments - Scanning workspaces for sneaky risk hotspots is like playing detective to sniff out exposure clues. Review tasks and layouts regularly and update your risk matrix as the situation evolves. A dynamic risk check keeps your safety measures both sharp and relevant. WHO: Risk Assessment Q&A
  8. Enhance Workplace Ventilation - Fresh air delivery is like turning on the world's biggest air purifier: it dilutes any lurking aerosols. Crack windows, upgrade HVAC filters, and avoid recirculating stale air to keep everyone breathing easier. A well-ventilated space is your invisible ally against airborne particles. WHO: Ventilation Advice
  9. Provide Mental Health Support - The pandemic is a marathon for the mind as well as the body, so check in with teammates who might feel stressed or isolated. Offer counseling resources, relaxation techniques, and virtual hangouts to boost morale. Keeping spirits up is just as important as keeping cases down. WHO: Mental Health Resources
  10. Stay Informed and Compliant with Health Guidelines - Rules and recommendations can shift faster than a viral mutation, so bookmark reputable sites and schedule regular policy reviews. Synchronize your workplace plan with the latest advice to keep everyone on the same page. Continuous learning is the secret sauce in a safe, agile workplace. OSHA: Updates & Compliance
