A respect for the water and an understanding of associated dangers are necessary for safety just about everywhere. General rules and routines should be borne in mind at all times.

1-Swimming pool users should be aware of water depths indicated on the pool sides.
2- There should be no running on the poolside; wet floors can be slippery and consequent falls can cause injury.
3-After a meal, food should be allowed to digest for at least 1.5 hours.
4-Swim hats should be worn by those with long hair, or the hair should be tied securely so that it cannot cover the face and especially the mouth.
5= Sweets or chewing gum should be avoided. It is dangerous to enter the water with these in the mouth.

Introduction to Life saving and Life Support (water safety)

Everyone involved in any water sport should learn the basic principles of lifesaving and life support. Although over the years there has been a gradual reduction in the number of drowning accidents in the UK, there are still approximately 500 fatalities every year. In a large proportion of these water-based accidents, the victims or casualties are within a few meters of safety.

Drowning is death caused by asphyxia (insufficient oxygen reaching the tissues of the body) due to immersion in water. Near-drowning is when a casualty survives an immersion incident.

Drowning and accidents in and around water follow a general pattern which can best be described as a chain of linked events. Each of the links can lead to direct injury or to the next link. The links are:
Lack of education
Lack of safety advice
Lack of protection
Lack of supervision
Inability to cope
Drowning can occur in any depth of water, and may depend on the age, health and swimming ability of the individual, and the water and weather conditions prevailing at the time.

Stay safe by following a few simple guidelines:

1-Always swim with a partner: every time even experienced swimmers can become tired or get muscle cramps, which might make it difficult to get out of the water. When people swim together, they can help each other or go for help in case of an emergency.
2- Get skilled: Speaking of emergencies, it's good to be prepared. Learning some life-saving techniques, such as CPR and rescue techniques, can help you save a life.
3-Know your limits: Swimming can be a lot of fun — and you might want to stay in the water as long as possible. If you're not a good swimmer or you're just learning to swim, don't go in water that's so deep you can't touch the bottom and don't try to keep up with skilled swimmers.
4-Swim in safe areas only: It’s a good idea to swim only in places that are supervised by a lifeguard.
