What PPE is typically required for work on B28 systems?

• A. Hard hat and steel-toed boots only.
• B. Flame-resistant clothing, eye protection, gloves, and respiratory protection when leaks exist or in confined spaces.
• C. Standard cotton coveralls and no eye protection.
• D. Safety glasses only.

Answer: (B)

Working on B28 systems involves flammable refrigerants and the possibility of leaks that can ignite or release harmful vapors. The most appropriate PPE includes flame-resistant clothing, eye protection, gloves, and respiratory protection when leaks exist or you’re in confined spaces. Flame-resistant clothing helps reduce burn injury if a spark or flame exposure occurs while working near energized components or during leaks. Eye protection shields eyes from refrigerant splashes and chemical irritation. Gloves protect hands from cold exposure and chemical contact, and they also provide better grip when handling fittings and tools. Respiratory protection is crucial in leaks or confined spaces because refrigerant vapors can displace oxygen or cause toxicity; a suitable respirator helps prevent inhalation hazards and supports safe breathing conditions. Other options miss essential protections, such as skin and eye safety, inhalation risks, or ignition protection, which is why this combination is the right choice.
