What safety equipment is required at all pools?

The requirement for safety equipment at all pools is primarily focused on preventing drowning and ensuring the safety of all pool users. This makes the presence of lifesaving equipment crucial. The shepherd's crook and ring buoys are specifically designed for rescue situations in aquatic environments.

The shepherd's crook is a long pole with a hook at one end that allows a lifeguard or safety personnel to reach someone in distress without having to enter the water, which can sometimes be unsafe. Ring buoys, often attached to a line, provide a flotation device that can be thrown to someone struggling in the water, enabling them to stay afloat while help is on the way.

This combination of equipment is essential for quick response to emergencies that could arise in a pool setting. While a first aid kit and fire extinguisher are also important in providing overall safety, they do not specifically address aquatic rescue needs. Safety goggles are useful for protection against chlorine and other chemicals, but they do not play a role in emergency rescue situations like the shepherd's crook and ring buoys do. Thus, the correct answer emphasizes the necessity of dedicated lifesaving equipment to enhance safety at pools.
