Survival clothing
Identifies survival clothing.
Understanding this sign
Green square or rectangular signs identify emergency escape routes, safety facilities, and rescue equipment.
Follow the complete wayfinding system and local emergency plan. A symbol alone does not establish a safe route.
What Counts as Survival Clothing
E056 marks the stowage of survival clothing, principally immersion suits, the insulated, watertight one-piece suits donned before abandoning ship into cold water, together with related garments such as anti-exposure suits and thermal protective aids kept at the same station. The pictogram shows a full-body suited figure, immediately distinguishable from the lifejacket signs, because the two kinds of equipment answer different threats.
A lifejacket keeps the airway above water; survival clothing keeps the body warm enough to still be alive when help arrives. In cold seas, hypothermia and cold shock kill protected, floating casualties, so flotation without insulation only changes what the casualty dies of. E056 locates the equipment that addresses the temperature problem, and on cold-water routes it is checked in drills with the same seriousness as the lifeboats themselves.
Cold Water Determines the Stowage Plan
Cold incapacitation begins within minutes of immersion: hands stop gripping, swimming fails, and useful survival time in near-freezing water without protection is measured in fractions of an hour. An immersion suit extends that window dramatically, but only if it is on the body before entry. That means suits must be stowed where people actually are, in cabins, near watch stations, and at the embarkation deck, rather than centralised in one distant locker.
SOLAS carriage requirements reflect this, providing immersion suits for persons on board cargo ships, with additional suits at remotely located work stations such as forward mooring areas so a crew member does not have to travel the length of the vessel to dress for survival. Each stowage point is a candidate for E056 signage, and scattered stowage without signage simply multiplies the places a suit can be misplaced.
Donning Time Is a Trained Skill
Immersion suit performance standards demand that the suit can be unpacked and donned quickly without assistance, and the industry norm drilled aboard is donning within about two minutes. Achieving that with cold hands, on a moving deck, over clothing, requires practice; abandon-ship drills routinely include timed suit donning for this reason, and crews learn details like leaving boots on or off per the suit design and fitting the hood and face seal last.
Signage supports the drill economy. E056 on the cabin locker, at the muster point, and at remote stowages removes the search step from an already tight timeline and shows visitors, riding crews, and new joiners where their suit lives before they ever need it. Familiarisation checklists for people joining a vessel routinely include locating the assigned suit on day one, and the sign is what makes that item quick to complete.
Offshore, Fishing, and Cold-Route Operations
The heaviest users of E056 are the sectors where cold-water abandonment is the design case: offshore oil, gas, and wind operations with helicopter and crew-transfer exposure, fishing vessels working high latitudes, and cargo ships on winter North Atlantic, Baltic, and polar routes, where polar operation rules add further personal survival equipment. In these fleets, survival clothing stowage is inspected as rigorously as lifeboats.
Suit stowage marked with E056 should be kept dry, accessible without keys or tools, and stocked with suits in surveyed condition, with zippers waxed and seams tested at service intervals. Manufacturers specify pressure or air testing of the suit at multi-year intervals, usually carried out by approved service stations. A signed locker containing a perished suit passes the wayfinding test and fails the survival one.
Where you will see E056
Offshore oil, gas, and wind operations, high-latitude fishing fleets, and cargo ships on winter North Atlantic, Baltic, and polar routes are the heaviest users, signing suit stowage in cabins, near watch stations, at the embarkation deck, and at remote work areas such as forward mooring stations. The sign on cabin lockers and muster points removes the search step from a donning timeline drilled at about two minutes, and helps new joiners locate their assigned suit on day one.
Common questions about E056
What does the survival clothing sign mean?
ISO 7010 E056 indicates where survival clothing is stowed, chiefly immersion suits and similar thermal protective garments worn before entering cold water in an abandon-ship situation. It is a green safe condition location sign, separate from the lifejacket signs, because thermal protection and flotation are distinct pieces of equipment.
How fast do you need to put on an immersion suit?
Performance standards for immersion suits require that they can be unpacked and donned quickly and without assistance, and shipboard drills commonly train to a benchmark of around two minutes. Regular timed practice matters more than the number itself, since real abandonments involve motion, darkness, and cold hands.
Who is required to have immersion suits on board?
Under SOLAS, cargo ships must provide an immersion suit for every person on board, with extra suits stowed at remote work locations, and requirements extend further for vessels operating in polar waters. Passenger ship regimes differ and rely more on thermal protective aids in survival craft. Flag state rules and trading area define the exact obligation for a given vessel.
Is an immersion suit worn instead of a lifejacket?
It depends on the suit's approval. Some immersion suits are certified to provide the required flotation and self-righting performance on their own, while others must be worn together with a lifejacket. The suit's markings and the ship's training manual state which case applies, and drills should rehearse the actual combination.
