Which of the following is NOT a safety concern in the kitchen?

Rain damage is not a safety concern in the kitchen because it pertains to external weather conditions rather than the immediate risks associated with kitchen activities. The kitchen is an enclosed space where potential hazards like burns, falls, and choking can occur regularly due to cooking processes, the design of the kitchen environment, and the use of various utensils and equipment. Burns can result from hot surfaces or liquids, falls can happen due to slippery floors or tripping hazards, and choking can occur from improperly prepared or consumed food. Therefore, rain damage does not align with the specific safety issues that one would encounter in a kitchen setting.
