CTE Safety Systems & Standards 3 â Questions and Answers
Question 1: In a CTE health sciences lab, the term 'standard precautions' refers to:
- Using gloves only when blood is visible
- Treating all human blood and body fluids as potentially infectious (Correct answer)
- Washing hands after each patient contact only
- Wearing a gown only during surgical procedures
Correct answer: Treating all human blood and body fluids as potentially infectious
Standard precautions require treating all blood and body fluids as infectious regardless of the patient's diagnosis or appearance.
Question 2: What does the acronym RACE stand for in fire emergency response procedures?
- Run, Alert, Contain, Extinguish
- Rescue, Alarm, Contain, Extinguish/Evacuate (Correct answer)
- Respond, Assess, Call, Escape
- Remove, Alert, Close, Evacuate
Correct answer: Rescue, Alarm, Contain, Extinguish/Evacuate
RACE (Rescue, Alarm, Contain, Extinguish/Evacuate) is the standard fire response sequence used in schools and healthcare settings.
Question 3: A CTE construction student is working on a scaffold more than 10 feet above a lower level. OSHA requires:
- A safety net but no fall arrest system
- Fall protection such as guardrails, safety nets, or personal fall arrest systems (Correct answer)
- Verbal reminder from the instructor about falling risks
- A spotter standing below the scaffold at all times
Correct answer: Fall protection such as guardrails, safety nets, or personal fall arrest systems
OSHA's scaffolding standard (29 CFR 1926.502) requires fall protection for workers on scaffolds at heights of 10 feet or more.
Question 4: Which of the following best describes a 'near miss' in a CTE safety context?
- An accident that results in minor injury
- An unplanned event that could have resulted in injury but did not (Correct answer)
- A planned safety drill where students simulate accidents
- A fire alarm that turns out to be a false alarm
Correct answer: An unplanned event that could have resulted in injury but did not
A near miss is an unplanned event that had the potential to cause injury or damage but did not, and should be investigated to prevent future incidents.
Question 5: In a CTE culinary arts lab, the MOST appropriate way to cool a large pot of hot soup quickly and safely is:
- Leave it on the counter at room temperature overnight
- Place it directly into the refrigerator while still boiling
- Divide into shallow containers and use an ice bath to cool rapidly (Correct answer)
- Cover tightly and let it cool inside the oven with the door open
Correct answer: Divide into shallow containers and use an ice bath to cool rapidly
Dividing hot food into shallow containers and using an ice bath rapidly moves food through the temperature danger zone (41°Fâ135°F) to prevent bacterial growth.
Question 6: A CTE electrical technology student must work on energized equipment rated above 50 volts. OSHA's approach to electrical safety prioritizes:
- Working quickly to minimize exposure time
- Establishing an electrically safe work condition (de-energizing) before work (Correct answer)
- Using rubber gloves as the only required precaution
- Posting a warning sign and continuing work
Correct answer: Establishing an electrically safe work condition (de-energizing) before work
OSHA and NFPA 70E require that equipment be de-energized and an electrically safe work condition established before work begins whenever possible.
Question 7: The NFPA 704 diamond on a chemical container provides emergency responders with information about:
- The manufacturer's contact information and price
- Health, flammability, reactivity, and special hazard ratings (Correct answer)
- Required disposal procedures and recycling codes
- Storage temperature ranges and shelf life
Correct answer: Health, flammability, reactivity, and special hazard ratings
The NFPA 704 system uses a four-section diamond to communicate health (blue), flammability (red), reactivity (yellow), and special hazard (white) ratings on a 0â4 scale.
