Life Saving Equipment and Survival at Sea
In any emergency or survival situation, the most important factor is the attitude of the people involved. A positive attitude can make a tremendous difference for survival. Having the appropriate life-saving equipment in good working order is important. Every seaman should know the ship, including location and operation of safety devices, hatches and exits from compartments, as well as the ship’s emergency procedures. Safety drills and safety training should be conducted on a regular basis and noted in the ship’s log. Emergency equipment needs to be checked and serviced regularly and replaced when necessary.
Everyone on a vessel needs to be involved with safety. The consequences for neglecting safety measures can be tragic. The old saying “one hand for you, the other for the ship” is a good rule to follow, even in calm weather. All passengers as well as crew on a vessel should be apprised of safety procedures. “The Captain goes down with the ship” really means that you are ultimately responsible to make sure that all crew members and passengers are familiar with safety procedures and techniques. You should always consider the safety of your own crew and passengers when assisting another vessel in distress. Don’t endanger yourself or your crew.
Log all injuries and administer proper first aid. Any injury requiring more than standard first aid must be reported to the Coast Guard. Your log is a legal document. State and Federal law requires that the operator of a vessel must report an accident involving any of the following: the death of a person, an injury requiring more than standard first aid, the disappearance of a person from the vessel that would indicate death or injury, total property damage to boats, docks, etc. involved in the accident that exceeds $500.
A float plan should always be filed with someone that knows the boat information and the estimated time of return. This person would be responsible to notify the Coast Guard of an overdue vessel. The essential elements of a float plan includes the intended destination and estimated time of arrival at that location, a description of the vessel and its state registration number or documentation number, the vessel’s radio call sign, the names of all crew onboard, and alternative plans in case of bad weather.
Every vessel needs to have a Safety Plan. This should include contingency plans for every type of emergency, including fires, grounding, criminal acts, collisions, etc. Information should include instructions for the crew to stop or minimize the damage or effects of the emergency. Methods for providing timely instructions to passengers and moving passengers to other spaces should also be included. After any drill, debriefing of the crew should occur and the safety plan should be updated, if needed. Unplanned drills can test the ability of the crew to work through unexpected situations. Crewmembers that have specific duties during an emergency situation need to be familiar with their station and responsibilities. A station bill or muster list should be prepared for each type of emergency. This is a document that lists the names of all crew members and their duties connected with emergencies. The preparation and signing of the station bill is the responsibility of the master of the vessel. The master is also responsible for seeing that all crew members are familiar with their duties. Alarm signals are part of the station bill, and these signals should become second nature to the crew. Station bills and muster lists must be posted in a conspicuous location in the crew’s quarters prior to the start of the trip. As a seaman on a vessel, it is your responsibility to know your duties and stations, as well as how to operate all equipment for those duties and stations. All drills and trainings, as well as injuries, need to be noted in the ship’s log. If a seaman dies during a voyage, the following must be noted in the Official Ship’s Log: an inventory of money and property, statement of wages due and a statement as to deductions that need to be made from the wages. The Official Ship’s Log should be signed by the master and chief mate.
A vessel’s ability to contain flooding and fire and to withstand damage depends largely on watertight doors, hatches, and other closures. Doors and hatches should be in good working order, but the crew must be trained to secure them during fire or emergency drills.
The Captain must make sure he and the crew complies with drug prevention policies and screening. Have each crew member sign a drug and alcohol policy.
Safety Equipment
Have a good set of tools available in the event of an emergency. Have an abandon ship bag and all crew members should know its location.
Emergency Positioning Indicating Radio Beacon (EPIRB) is a small transmitter that sends out emergency signals to rescue services. Their use is limited to Mayday-type emergencieswhere a vessel is in danger of sinking or a life threatening injury.
It is important to register your EPIRB and to notify them of any changes that occur after it is registered. Generally they come with the battery disconnected, so it is important to make sure that the battery is in place. They should be tested monthly for one second during the first 5 minutes of any hour. Avoid false alarms when transporting or moving the device.
Type I is automatic and will float free. Type II is manual. Both work off satellites. Since rescue vessels will be directed toward the EPIRB signal, it is important to keep the EPIRB in the area of the people on the vessel.
46 CFR 180.64 gives the requirements for EPIRBs. Each vessel that operates on the high seas, or that operates beyond three miles from the coastline of the Great Lakes must have on board FCC Type Accepted Category I EPIRB installed to automatically float free and activate.
Personal Floatation Device (PFD) Federal regulations require that there be at least one Coast Guard approved life jacket for each person on a vessel (46 CFR 25.25-5) A vessel may not be used unless all the life jackets are in serviceable condition, readily accessible, legibly marked, and are of an appropriate size for each person on board.
While these are considered secondary (life rafts are primary), it is important to make sure the vessel has the proper number on board and that all crew and passengers know where they are stored. They should not be stored in plastic and should be readily accessible. Children’s life jackets should be stored in a different area than adult life jackets. Work vests should be stored in a different area than life jackets. Try them out individually to make sure they operate properly, especially the water lights and reflective material. If they are damaged they need to be replaced immediately. After use always air-dry each floatation device thoroughly and away from any direct heat source. Then store it in a dry, well-ventilated, easily accessible place on board the boat.
Type I has 22 lbs. of buoyancy in adults (11 lbs. in children) and are designed to float with the person’s head up.
Type II are near shore buoyant vests. State Law requires that children 6 years and under must wear this.
Type III is floatation aids and is popular because they are comfortable.
Type IV are throwable devices, such as a ring life buoy or buoyant cushion. These do not take the place of a life jacket.
Type V are hybrid inflatables and are the least bulky with CO2 inflation. Make sure you check it often.
Retro-reflective material is required on all life jackets used on commercial vessels. Each life jacket is required to have 31 square inches of retro-reflective material attached to the front and backsides. Life jacket lights are required on vessels in the ocean, coastwise, or in the Great Lakes. It must be securely attached at the front area of the shoulder. The power source must be replaced on or before its expiration date.
46 CFR 180.7 contains the requirements for life buoys and life jackets for T-Boats.
Practical Exercise: Using the link, find the CFR section 180 and read the requirements for life buoys and life jackets, flares, etc.
Immersion Suits are Coast Guard approved insulated, dry suits designed to reduce the effects of hypothermia.
Signaling Devices include any device used to signal in the event of an emergency. Flares and rockets are good for three years. When deploying, hold them down wind and watch for slag to prevent getting burned. Know how to engage them. SOLAS approved flares are much more powerful than Coast Guard approved flares as they adhere to a higher standard. They are good for short distances day or night, while VHF, EPRIB, etc. are good for long distances. The CFR’s contain flare requirements for Uninspected Vessels (33CFR175.139) and for Inspected Vessels (46CFR180.68). Other signaling devices would include mirrors, whistles, and waving arms.
Abandon Ship Procedures
If you have to jump in the water when abandoning ship, your legs should be extended straight down and crossed at the ankles. Only enter a raft when it is absolutely necessary and try to stay near the vessel as you will be easier to spot. Send a MAYDAY and make sure that you bring the EPIRB with you into the raft. Remember that rescue will be coming for your EPIRB as that is what is sending the signal. Assure passengers that help has been requested and that it is important for them to follow stated procedures. A positive attitude can make the difference for survival. Everyone should put on warm clothes or an immersion suit, if applicable, as well as life jackets. Avoid entering the water, if possible. Don’t jump into cold water, but gradually lower yourself into it, if it is necessary. Once in the water, do not swim unless attempting to get to the raft as swimming causes rapid heat loss. Keep all survivors together. Conserve heat by bringing your arms and legs close to your body, keeping your head out of the water. Try to get to the raft or floating debris as quickly as possible, getting yourself out of the water. Put someone in charge and ration food and water. Give everyone jobs to do. Avoid sea-sickness with pills, if available. Other things to prevent seasickness would be to avoid excessive food or drink, especially alcoholic beverages prior to the trip. Learn to hand-line.
When requesting helicopter MEDEVAC assistance, provide the Coast Guard with your accurate position, vessel size and type, course and speed, local sea and weather conditions, and wind direction and velocity. Give as much information regarding the victim, including his or her symptoms and whether or not the person is ambulatory. If there is any change, advise them immediately. If the person expires, let them know as the air crew is at risk during a MEDEVAC.
For a helicopter rescue, don’t grab the cable until it touches the water (grounds out). Don’t tie the sled to the boat. Light the rescue area on your vessel as much as possible, if at night. Be careful not to shine lights at the helicopter. Lash any rigging or booms. Advise the helicopter of the lift area. The stern is usually the best area for a hoist. Remember that there will be a lot of noise from the helicopter, so voice communication will be difficult. Do not tie off the hoist cable. Don’t wear a ball cap. If a litter is required, make sure the patient is strapped in, face up, with life jacket on. Deck personnel should give the thumbs up to the helicopter to indicate the hoist is ready.
Man Overboard
If a person falls overboard, avoid running over them, throw a floatation device with a strobe light attached, and keep the person in sight. Point and give direction to the person operating the vessel. Have a crew member put on a life jacket or immersion suit with an attached safety line and be ready to jump into the water to assist the person overboard, if necessary. Approach carefully from downwind, throw life line and assist them on board. If the person is not located immediately, notify the Coast Guard and other vessels nearby, utilizing the radio. This would be a Pan Pan call. Continue to search for the person until released by the Coast Guard.
A Williamson Turn can be used to return to the position where the person fell overboard. When the person falls overboard, the person at the helm should immediately alter course 60 degrees in the direction of the person overboard, then full opposite rudder until back on the reciprocal track. Don’t touch the throttle keeping your speed constant. Keep the person in constant view, with all hands assisting in recovering this person.
If you fall overboard yell prior to hitting the water. Don’t panic, assume the help position and conserve body heat (drinking alcohol speeds up heat loss because it dilates blood vessels). If you can, stay out of the water as heat loss is greater in the water than in air. Hypothermia occurs with extreme heat loss, with most heat being lost from the head, chest and groin areas of the body.
If you see a person fall overboard, yell “Man Overboard” as loud as possible and indicate which side of the boat the person fell from. Simultaneously point to the person and give information to the helmsman. Keep visual contact with the person overboard. The helmsman should immediately cut the throttles and avoid running over the person in the water. They can also take GPS bearings, if possible (MOB button). Throw floatation with a strobe light. The mate should put on a PFD in case they need to enter the water and retrieve the person against the wind and current, pulling them safely on board. Treat for shock.
Practical Exercise: Conduct a Man Overboard drill and the Williamson Turn. Make sure you know all the steps. State it’s a drill and never let someone actually enter the water.
Heat Injuries
Heat injuries are more common among seamen that work near the engine room because of the heat produced by the engines. Knowing the symptoms of injuries from excessive heat can lead to prompt treatment and prevent it from getting worse. The three heat injuries are heat exhaustion, heat cramps and heatstroke in order of less severe to most severe.
Heat exhaustion symptoms include pale, cool and clammy skin. Nausea, vomiting, headache, and restlessness are common. The person should be laid down in a cool place. Bathe the person with cool water and give cool water or beverage with electrolytes. Symptoms of heat cramps are painful contractions of the muscles. Give plenty of liquids containing electrolytes. Heatstroke is an extremely serious situation, and prompt action can make the difference between life and death. It is characterized by an extreme elevation of body temperature. The skin appears hot, flushed, and dry. Body temperature can rise to 105 degrees. Convulsions, vomiting and profound shock can follow. Rapid reduction of the body temperature using an ice bath or ice water soaked towels is the key. Get professional medical advice via the radio, if possible.
Cold Water Immersion
There are two major concerns when a person enters cold water, hypothermia and drowning (or near drowning). Hypothermia can exist even if the water is not cold as it will still be colder than body temperature, which is 98.6 degrees F. If a person is in the water for a long period of time, even in a tropical environment, he or she can suffer from hypothermia. Factors that affect hypothermia are water temperature, victim’s physique, protective clothing worn, sea conditions and victim’s behavior in the water. The more active a person is in the water the faster the heat loss will occur. The two goals in treatment of hypothermia are to prevent cardiopulmonary arrest and to stabilize the core temperature. Try not to lift the person vertically from the water. Gently remove wet clothing and wrap the victim in warm blankets. Do not use artificial heat. Get medical advice via radio as this is a serious situation.
Remember that shock can occur even with minor injuries. A victim should always be monitored for shock, no matter what the injury is. A person can die from shock even when the injury is not life-threatening.
