Water Rescues


To give firefighters an overview of the techniques and hazards associated with water rescues.

water rescues
Water Rescues

Learning Outcomes:

  • State the hazards involved in water rescues
  • State the various rescue methods
  • Describe the appropriate casualty care.
water rescue
Water Rescue

There are 2 types of current generated in a river:

  • Laminar

Water Rescues

Helical Flow:

Water Rescues


  • Weirs: serious hazard
  • Eddie: an upstream current that forms behind an object in the water
  • Undercut: a rock that has been worn or eroded, usually below the waterline
  • Strainer: trees, rubbish, old bedsteads, allow water to flow through, but not you.
water rescues7
Water Rescues
  • Debris: Old bedsprings, bicycles, shopping trolleys, etc
  • Entrapment: getting feet caught in rocks, etc.

If the water is deeper than 1m, the best way to cross is to float or swim.

saving a drowning victim
Saving a Drowning Victim
  • Reach
  • Throw
  • Wade
  • Row
  • Swim with an Aid
  • Swim and Tow.
  • First try to throw a buoyant object
  • Try to reach victim with a line or rope
  • Next try a boat (if available)
  • Swimming rescues should only be attempted by a qualified person
  • If a line is attached to the rescuer it must be easily jettisoned.
mammalian diving reflex
Mammalian Diving Reflex
  • There have been several cases of recovery after being submerged for considerably longer than the accepted 4 minutes
  • This is attributed to a phenomenon called the mammalian diving reflex
  • This is the body’s ability to channel blood away from ‘non-vital’ functions and direct it to the brain
  • For this reason do not give up just because its more than 4 minutes.
line rescues
Line Rescues
  • Stand sideways to the river
  • Look for obstacles, tree branches, etc
  • Throw the line upstream and allow it to float down to the victim
  • Once the person has the line the current will usually swing them into shore, like a pendulum, be aware of any rocks which may be in their path.
line rescues12
Line Rescues
  • If access to both sides of the water hazard is available a tag-line rescue can be used
  • This is simply brought to a level with the stranded or trapped person
  • A floating tag-line is a line stretched across with a buoyant object tied in the middle for the victim to hang onto.
stabilising the casualty
Stabilising the Casualty
  • In many circumstances it will be necessary to stabilise the casualty prior to rescue
  • A line or a lifejacket can be thrown to the casualty
  • Mouth to mouth can be given if the casualty is trapped in shallow water
  • Consider using a BA set to allow the casualty to breath while rescuing.
casualty care
Casualty Care
  • Casualty’s must be transported to hospital following drowning or near drowning due to a condition known as ‘secondary drowning’
  • In this the casualty’s lungs fill with fluid in response to the entry of water
  • This can occur up to 24 hours after rescue
  • It may also be necessary to treat the casualty for any pollutants in the water
  • This also applies to any rescuers affected.
rescues from ice
Rescues from Ice
  • Victims can rescue themselves but panic often makes this unlikely
  • Reassure the victim and try to get them to stop ‘thrashing’ about
  • They should try to crawl forward on their stomachs until their hips are at the edge of the ice then roll clear.
rescues from ice17
Rescues from Ice
  • Never attempt an ice rescue without adequate preparation
  • All rescuers on the ice must have safety lines around them
  • Your safety depends on being able to recognise unsafe conditions
  • Only minimum numbers on the ice.
rescues from ice18
Rescues from Ice
  • Spread rescuers weight as much as possible, use ladders and attach lines to ladders as well as rescuers
  • If the ice breaks and the ladder falls in, it may be possible to use it to climb out of the water
  • On reaching the victim attach a lifejacket or grasp them firmly.
rescues from ice19
Rescues from Ice
  • The rescuers will have to do all the work as the victim will probably be suffering from hypothermia and unable to assist in their own rescue
  • Tag-line rescues can also be used for ice rescues if the victim has not been in too long.

Assessments will be based on this lesson and the corresponding study note:

  • State the physiological effects of cold water immersion
  • Demonstrate the treatment for hypothermia
  • Demonstrate in-water survival techniques as a single survivor and in group conditions.
