VIII. WEAR YOUR PFD
In approximately 80 percent of all boating fatalities, the victims were not
wearing a PFD. Most fatal accidents happen on calm sunny days. This
inflatable PFD is much more comfortable to wear than other PFD types.
Get into the habit of wearing this PFD. Non-swimmers and children
especially should wear a hybrid or non-inflatable PFD at all times when
on or near the water.
IX. HYPOTHERMIA
Prolonged exposure to cold water causes a condition known as
hypothermia - a substantial loss of body heat, which leads to exhaustion
and unconsciousness. Most drowning victims first suffer from
hypothermia. The following chart shows the effects of hypothermia:
PFDs can increase survival time because they allow you to float without
using energy treading water and because of their insulating properties.
Naturally, the warmer the water, the less insulation you will require.
When operating in cold waters [below 60°F (15.6°C)] you should
consider using a coat or jacket style PFD or a Type V Thermal
Protective PFD as they cover more of the body than the vest or belt
style PFDs.
