How should protective barriers be used around B28 equipment?

• A. Barriers are optional and rarely used
• B. Barriers should be removed during operation
• C. Barriers protect from impact, reduce ignition risk, and separate from occupied spaces
• D. Barriers should be decorative and not functional

Answer: (C)

Protective barriers around B28 equipment create a safe zone that serves three purposes: they shield the equipment from accidental impact, reduce ignition risk by keeping sources of heat or sparks at a safe distance, and keep the area away from occupied spaces. This setup helps prevent damage during operation, limits exposure if a leak or fire occurs, and gives space for safe access and response. Barriers are not optional or decorative; they must remain in place to maintain separation and safety around flammable refrigerant systems.
