One excellent addition to your assembly of swimming pool safety products and swimming pool barriers is a safety line.
If there is an emergency and someone is in distress, a safety line can come in handy to help rescue another person. You simply throw them the line to grab and pull them to safety.
Experts recommend this because a secondary drowning often occurs when those who think they are strong swimmers try to save another person. Those uncertified in water rescue should try, at all costs, to use proper precautions when trying to help a swimmer in distress.
