Which of the following is NOT considered a safety feature in a barn?

Automatic lighting, while it can enhance visibility and convenience in a barn, does not directly address health or safety concerns in the same manner as fire extinguishers, non-slip flooring, and first aid kits. Fire extinguishers are crucial for fire emergencies, non-slip flooring helps prevent falls and injuries, and first aid kits provide immediate assistance in case of accidents or injuries.

In contrast, automatic lighting is more about efficiency and general utility rather than a dedicated safety feature. It may improve the comfort of working within the space but does not have the protective qualities that the other options provide. Understanding the specific roles that each of these items plays in safety management within a barn environment can help prioritize what facilities and features are genuinely essential for protecting both people and the animals housed there.
