How should refrigerant cylinders be stored in B28 facilities?

• A. Lying on their sides away from heat sources
• B. Upright, secured storage away from heat sources, in ventilated areas with proper labeling and spill containment
• C. Stacked in unventilated areas
• D. Stored in occupied spaces

Answer: (B)

Refrigerant cylinders must be stored in a way that minimizes exposure and hazard if a leak occurs. Keeping them upright, secured to prevent tipping, and placed away from heat sources reduces the risk of valve damage, accidental releases, and pressure buildup. Upright storage helps protect the valve and any safety devices, and minimizes the chance of liquid from the cylinder escaping through the valve if the cylinder is jostled. Securing them stops them from falling, rolling, or being struck, which is especially important in busy work areas. Placing cylinders in ventilated areas prevents accumulation of refrigerant vapors, which can be flammable or displace oxygen, creating dangerous conditions for occupants. Clear labeling ensures everyone knows what’s inside and the associated hazards, while spill containment provides a backup to catch leaks and prevent environmental or floor contamination. Storing cylinders in occupied spaces is avoided because it elevates risk to people in the area.
