CA Flagger Personal Protective Equipment 2 — Questions and Answers
Question 1: What ANSI/ISEA class of high-visibility vest is required for flaggers working on federal-aid highway projects?
- Class 1
- Class 2
- Class 3 (Correct answer)
- Class E
Correct answer: Class 3
Class 3 high-visibility safety apparel provides the highest level of visibility and is required for flaggers on federal-aid highways.
Question 2: Which color is NOT approved for high-visibility safety vests worn by California flaggers?
- Fluorescent orange-red
- Fluorescent yellow-green
- Fluorescent orange
- Solid navy blue (Correct answer)
Correct answer: Solid navy blue
Navy blue does not meet ANSI/ISEA 107 standards for high-visibility apparel because it lacks the required fluorescent and retroreflective properties.
Question 3: When must a flagger wear a hard hat in a work zone?
- Only when operating heavy equipment
- Whenever there is overhead hazard or falling object risk (Correct answer)
- Only during nighttime operations
- Only when required by the flagger's supervisor on that day
Correct answer: Whenever there is overhead hazard or falling object risk
Hard hats are required whenever there is a risk of overhead hazards, such as falling debris or objects from construction activity.
Question 4: A flagger's safety vest has faded and the fluorescent material is no longer bright. What should the flagger do?
- Continue using it until end of the project
- Wash it with brightening detergent and reuse
- Replace it with a compliant high-visibility vest (Correct answer)
- Wear a second vest over it to compensate
Correct answer: Replace it with a compliant high-visibility vest
PPE that no longer meets visibility standards must be replaced immediately, as faded material fails to provide adequate protection.
Question 5: Which type of glove is most appropriate for a flagger directing traffic in a work zone?
- Thin latex surgical gloves
- Heavy leather welding gloves
- High-visibility or brightly colored work gloves (Correct answer)
- No gloves are recommended as they interfere with signaling
Correct answer: High-visibility or brightly colored work gloves
High-visibility gloves improve the flagger's hand signals to motorists and also protect against minor hazards.
Question 6: What is the primary purpose of retroreflective material on a flagger's vest?
- To identify the flagger's employer
- To make the flagger visible to drivers at night or in low-light conditions (Correct answer)
- To protect against heat from the sun
- To indicate the flagger's certification level
Correct answer: To make the flagger visible to drivers at night or in low-light conditions
Retroreflective material reflects vehicle headlights back toward the driver, making the flagger visible during nighttime or low-visibility conditions.
Question 7: If a flagger is working near loud equipment exceeding 85 dB, what PPE is required under Cal/OSHA regulations?
- Safety glasses only
- Hearing protection such as earplugs or earmuffs (Correct answer)
- A full-face respirator
- A hard hat with noise dampening
Correct answer: Hearing protection such as earplugs or earmuffs
Cal/OSHA requires hearing protection when noise levels reach or exceed 85 dB as an 8-hour time-weighted average.
