With the improvement of modern people's living standards, more and more people choose to travel to the seaside during vacations. In the process of enjoying the blue sky and the beach, there are also some dangerous things happening, such as drowning. This requires some lifesaving equipment.

The first is the life chair. The lifesaving chair is a special seat for swimming lifeguards to observe the situation of the swimming area from a height. It is a safety auxiliary measure and belongs to the swimming pool lifesaving equipment. The height of lifesaving chairs used in general swimming pools is 1.9 meters, and those used in larger swimming areas such as beaches are 2.5 meters.

There are two types of lifesaving chairs: standard type and luxury type. The material used in the standard type is 202 stainless steel, and the material used in the luxury type is 304 stainless steel. The style is the same, the difference lies in the material used.

Next is the life buoy. A lifebuoy is a kind of water lifesaving equipment, usually made of cork, foam plastic or other light materials with a small specific gravity, and covered with canvas, plastic, etc. Lifebuoys for swimming practice can also be made of rubber and filled with air, also known as rubber rings.

It should be noted that the swimming ring is not a life buoy and must not be used as a life-saving appliance. The national standards implemented by swimming rings and life buoys are different. Life buoys play a life-saving role and have many auxiliary functions; while swimming rings are defined as water toys, they only implement the standards for playing swimming rings. Therefore, compared with the real lifebuoy, the toy swimming ring is easy to be damaged and leaked, has poor compression resistance, and is extremely easy to burst. The plastic surface is slippery and slippery in water, which is difficult to grasp. Auxiliary or protective, dangerous if taken to deep water.
