CompTIA A+ Core 2 (220-1202) — Question 136

A technician is 3-D printing high strength, carbon fiber-based filament parts for a customer order. Which of the following is the most important for the technician to use?

Answer options

• A. Steel-toed boots
• B. Air filter mask
• C. ESD mat
• D. Antistatic bags

Correct answer: B

Explanation

The correct answer is B, as an air filter mask is essential to protect the technician from inhaling harmful particles released during the 3-D printing process. The other options, while important for safety and equipment protection, do not directly address the respiratory hazards posed by carbon fiber dust.
