Class B gas types such as CO2 and HALO bottles shall not be permitted in which area?

• A. The kitchen cooking area
• B. The mechanical room
• C. The outdoor dining area
• D. The employee lounge

Answer: (A)

Gas-type extinguishing agents, like CO2 and HALO, work by displacing the breathable air in a space. That makes them highly effective for certain fires, especially in unoccupied or specially protected rooms, but they pose a serious asphyxiation risk to anyone inside the area when released. A kitchen cooking area is a place where people are routinely present and where there are open flames and cooking oils, so releasing a gas-based extinguisher there could endanger staff before the fire is controlled. For that reason, gas-type bottles are not permitted in a kitchen cooking area. In such spaces, appropriate extinguishing methods (like Class K for cooking oils) are used to protect people while addressing the fire risk.
