    Let’s start!

    1. What is an Immersion Suit?

    An immersion suit is a protective suit used to protect crew members from hypothermia in the cold water or any miseries or any emergencies occurring in high seas. That is why it’s also known as a rescue suit.

    The first immersion suit was known in 1930 when a New York firm, American Life Corporation, proposed fishing firms the Immersion Suits as their safety suits for crew members.

    This suit allows a high jump of no less than 4.5 meters into the water without fear of being injured or damaging the immersion suit.

    An immersion suit is made up of neoprene, a type of rubber and entirely waterproof and can bear any temperature that could be high or low.

    Moreover, an immersion suit covers the wearer’s whole body but the face, which is covered with a neoprene face cover and a neoprene face seal.

    2. What Are The Uses Of Immersion Suits?

    There are various uses of Immersion suits. These uses are as follows:

    • Immersion suits are designed to keep the wearer mild and safe from hypothermia in freezing water.
    • The seams in the immersion suits are all cornered and 100 percent waterproof so that no water enters or passes through the immersion suit.
    • To keep the body heat stable in the immersion suit, the inner surface of the suit is laminated with a metallic sheet.
    • There is a long zip in an immersion suit used to put on a mother and child to contain them at one time.
    • The immersion suit is light in weight and easy to carry in high seas.
    • Immersion suits extend the wearer’s duration in cold waters. It’s life-saving equipment for all fishermen. 

    3. What Are The Advantages Of Immersion Suits?

    There are many advantages of an immersion suit; some of them are given below:

    • An immersion suit helps to maintain the body heat for rescuing someone from the water.
    • Immersion suits are mapped out to rescue the crew members from death due to the uncovering and hypothermia type problems.
    • Immersion suits cover all the body and its magnitude to withhold water from entering into the immersion suit.
    • Immersion suits mainly reduce the severity of cold blows.

    All the three layers of immersion suit have their advantages, like:

    • The inner layer of the immersion suit is made up of microfiber that keeps air in it to provide protection against the cold.
    • The next after inner layer is a layer containing bubble-like film for waterproofing.
    • The last layer, or the outer layer, which is also called a nylon layer, opposes damage and retard fire.

    4. What Are The Features Of A Good Immersion Suits?

    An immersion suit is called a good Immersion Suit if it contains the following features:

    Figure 2: A good Immersion Suit

    Figure 2: A good Immersion Suit

    • The Immersion Suit can be Insulated and non-insulated and is wearable with a life jacket.
    • An immersion suit should contain a layer in the suit, which would cause water resistance.
    • Immersion suits should be World Wide Red in a highly visible color.
    • A good immersion suit should be unblocked and get dressed within a time limit of 2 minutes without any outward help or relief.
    • The person should be capable of a leap from a height of at least 4.5 meters in the water.
    • The immersion suit should be capable of covering the whole body except the face.
    • The retro-reflective binding must be suitable in immersion suits.
    • After wearing an immersion suit, ordinary work should be allowed to be fulfilled by the crew members.
    • The crew members must jump and go down a vertical ladder of at least 5 meters of length.

    5. How Long Is The Survival Time In An Immersion Suit?

    A new type of immersion suit adds 19 hours in an already existing IMO stipulated 6 hours of survival time in an immersion suit.

    The survival time also includes 2 minutes put on time, full protection for more than 4.5 meters, mainly hypothermia safety for more than 6 hours, and to oppose flame for more than 2 seconds.

    6. How Do You Wear An Immersion Suit?

    Following are the instructions for how to wear an immersion suit:

    Figure 3: How to wear an Immersion Suit

    Figure 3: How to wear an Immersion Suit

    9. What Are The Testing Requirements For An Immersion Suit?

    There are different administration states that the layer and termination of immersion suits experience collapse over time.

    The rate and seriousness may occur widely depending upon the distinct components and procedures working in the manufacturing of the immersion suits and all the conditions in which the immersion suit is set aside.

    However, under consummate conditions, the material and adhesive used have a limited life service and will automatically experience a reduction in strength or loss of water resistance with time.

    To ensure the preservation of sufficient strength and water resistance of seams and shutting down of immersion suits and anti-exposure suits with age, each suit must be exposed to an air pressure test at intervals.

    10. Do Immersion Suits Have An Expiration Date?

    At present, immersion suits do not have an expiration date. The life of the immersion suit is conditional on a lot of its care.

    But the immersion suits are much older than 10 or 12 years and must be examined very hypercritically.

    These fishermen keep wearing the immersion suit endlessly to ensure that their bodies do not drop the heat and are kept continuously warm and wrapped.

    Figure 7: Fishermen Immersion Suit

    Figure 7: Fishermen Immersion Suit

    Type 2

    The Second type of immersion suit is the one that is kept on all ships and boats.

    It is mandatory; without it, workers cannot be anticipated to work on the ship or oil rigs. Only during difficult situations, such immersion suits are worn by the workers.

    Type 3

    The last type of immersion suit is the Inflatable Immersion Suit. The inflatable immersion suit does not fully cover the person’s body.

    The inflated suit only covers a person’s legs and hands, keeping the person swimming and safety in critical situations. Because of the immersion suit’s prolixity, the suit is easier to carry and for transportation purposes than the previous two types.

    The immersion suits are also made with an emergency torch, a whistle, and a tagline attached to the suit of the rescued person. This is also known as the buddy line, which ensures that all the persons are together and no person gets lost in the water.

    14. What Is the Donning Time of An Immersion Suit?

    The donning time completely depends upon the crew member how quickly he puts on his immersion suit and saves himself from an emergency.

    It is better to practice donning before any type of such activity. If a member is giving a good practice time, then he could lessen his donning time from minutes to seconds. The donning practice includes:

    • Get the immersion suit out from the storage bag.
    • Put the weaker arm into the immersion suit first. Drag the hood of the immersion suit over your head with loose hands.
    • Put your free arm at last into the immersion suit. Drag the zipper of the immersion suit up with care and cover your face properly with it.
    • Make sure that all the tape and piping are safe to keep away from being ripped or injured. Do not raise the air bladder as late as you are in the water.

    If a crew member practiced it well, then the donning time of an immersion suit would be 60 seconds or less than that.

    • Keep away from direct sunlight and dry it while turning the suit inside out. Grease and oil must be cleared from the immersion suit with soft soap.
    • Check all the zippers for smooth working. Make the zippers smooth with a non-petroleum type product like canning paraffin, beeswax, or the substance suggested by the manufacturer.
    • The air bladderhelps to prop up the head and lift it out of the water. It also offers buoyancy. So maintenance of air bladder is very necessary.

    19. How to Store an Immersion Suit?

    The simplest way to store an immersion suit is as follows:

    • Place your immersion suit on the floor with the open zipper,
    • Twist the suit up from the middle to the top,

    26. What is an Inflatable Immersion Suit?

    The unique type of survival suit is the inflatable immersion suit. Inflatable immersion suits are recently manufactured.

    Its buoyancy stops the wearer from sinking. It helps to keep them floating face up. The immersion suit is waterproof. It shields the wearer from cold water-body contact.

    Furthermore, it is insulated to offer protection from fire. It’s recommended to wear it before inflation.

    Once the inflatable immersion suit has been put on, the wearer activates firing handles on compressed carbon dioxide cartridges.

    It punctures the cartridges and rapidly inflates the suit. This results in a highly buoyant and rigid shape suit. It also offers very high thermal retention properties.

    Like the inflatable boat, the inflatable immersion suit also possesses all precautionary properties. The suit has two or more vesicles in case it is ruptured, and the gas is discharged, another vesicle is available to be used.
