PERSONAL SAFETY SAR Crew Manual Chapter 02
A human body loses 25 times more heat when immersed in water, than in air of the same temperature.
In preparing to go out on a mission it is essential that all crew are properly prepared: 1. for a long and cold mission 2. for anything that might go wrong on the mission
Personal Protection If a mission turns out to be a long hard run to the last known position, and the crew are cold and exhausted when they reach that position they will be ineffective as a rescue resource.
Personal Protection If a mission goes wrong, and something unexpected happens to the rescue vessel, each crew member must be properly prepared for that emergency.
Personal Protection The run out to the casualty may well be made in adverse conditions, with low temperatures, a head wind, (and associated wind chill), sea and swell, in rain or snow, or spray over the vessel.
Personal Protection If you have forgotten to wear a toque under you helmet and your head gets cold, it will not be long before you are not going to be contributing much to the operation. The same goes for the lack of any other gear.
Personal Protection To increase your chances of survival in cold water Wear gear that fits you Wear gear that fits the weather Wear gear that fits the mission
Personal Protection Safety gear must provide five essential features Flotation Insulation Protection Mobility Visibility
A personal flotation device or lifejacket must be worn at all times by all crew in an open vessel, or when on the deck of a larger vessel. This personal flotation device must stay on the wearer in a 25 knot impact with the water.
Flotation A cruiser suit or anti exposure suit or flotation suit generally offer at least 15 pounds of positive buoyancy, and they satisfy this requirement, but reference is to be made to the approval labels in the suit. A dry suit generally does not fulfil this requirement, and will require wearing a PFD.
Flotation Some equipment vests are fitted with their own buoyancy and are therefore worn to provide the extra buoyancy to offset the weight of all the extra kit that may be carried.
Flotation Extra lifejackets are to be carried in case survivors brought on board require them. For suits, see slides on Protection
Body Heat Loss
Heat Loss Once the SAR crew is properly dressed the principal heat loss will be through: 1. the head, face and neck 2. the hands
A layer of good polypropylene, or higher grade of thermal underwear, will be of benefit in any prolonged operations out on the water in cold conditions. Try to avoid any cotton next to the skin.
Protection Helmets On any fast rescue craft crew members will be exposed to strong and sudden impacts, and accelerations/ decelerations. The chance of head injury is high. Helmets should be light, designed for use on the water
Helmets Protec Ace Water Helmet
Toque or Balaclava
Equipment Vest This should contain: Flashlight Strobe Latex gloves and artificial resuscitation mask Knife
Extra gear should be carried when embarking on a mission, it being unknown as to how long one is likely to be out. For this a water resistant bag should be used.
Gear Bag This should contain: Toque or hat, or balaclava, and goggles Extra gloves or liners, spare clothing Chemical hand warmers Phone No. and Identification Small amount of cash High energy snacks and water
Distress Flares Personal flares are no longer to be brought on board vessels
Maintenance and Cleaning
Use mild soap solution or mild non abrasive detergent if needed Rinse with fresh water and hang to dry in ventilated area Do not use harsh cleaning chemicals Do not store in direct sunlight Lubricate zippers DO NOT DRY CLEAN
Maintenance and Cleaning Small damage can be repaired, e.g small tears, damaged zips, open seams or small burns Severely damaged suits should be removed from service
Cold Water Survival
Preventing Hypothermia Whilst in a boat, the best protection is: Dry suit Wet suit Immersion Suit Exposure Coverall Multiple layers of dry clothing with water or wind proof outer layer
Hypothermia Symptoms Skin colour - pale or blue Restricted movement - slow and listless, uncoordinated and clumsy Shivering stops when severely hypothermic Slowing pulse and decreasing conciousness Unconciousness
