Lifebuoy refers to a kind of water life-saving equipment, which is usually made of cork, foam plastic or other light materials with small specific gravity, and is wrapped with canvas, plastic, etc. The lifebuoy used for swimming practice can also be made of rubber and filled with air, also known as a rubber band. Additionally, this term is also used to describe a person who is overweight, with a prominent circle of fat around their belly.

How to choose a lifebuoy correctly?

Check for air leakage before use. Pay attention to the seams or adhesive joints of the lifebuoy and pull slightly to avoid insufficient bonding strength and air leakage.

Reject "three no" products. Before purchasing, check the outer packaging for the factory name, address, implementation standards, warning signs, etc.

Due to the uneven quality, price, and application scope of lifebuoys, it is important to carefully select lifebuoys that meet the configuration requirements when purchasing.

1. Qualified lifebuoy products should have relevant material inspection reports, type test reports, and ship bolt inspection certificates.

2. At present, the reference cost price for qualified lifebuoy products in China is about 55 yuan/piece for polystyrene wrapped lifebuoys and about 100 yuan/piece for laminated polyethylene lifebuoys. Therefore, lifebuoys that are excessively cheap are likely to be products that cut corners and should be purchased with caution.

3. If conditions permit, businesses are required to conduct necessary checks on the weight, suture quality, strength, buoyancy, high temperature resistance, and damage resistance of lifebuoys in accordance with standard specifications.
