ISO E036 Lifeboat Sign

What ISO 7010 E036 Means

E036 marks the position of a lifeboat: a rigid, engine-driven survival craft carried so that everyone assigned to it can leave the ship and stay alive at sea until rescue arrives. The green square carries a pictogram of a boat descending on its falls with occupants aboard, and it belongs at lifeboat embarkation and stowage positions on every SOLAS vessel. Together with the rest of the shipboard E-series, it came into ISO 7010 through the alignment of IMO's lifesaving appliance location symbols with the international safety sign standard.

A lifeboat is the heavyweight of the survival craft family — enclosed against weather and fire on most modern ships, self-propelled, provisioned, and designed to be launched fully loaded. The sign tells passengers arriving from an assembly station that they have reached the craft itself, not merely another waypoint, which is why it is reserved for the boat positions and never used as generic escape route decoration elsewhere on deck.

Lifeboat, Not Rescue Boat

The nearest neighbor in the sign catalog is E037, and mixing them up misdirects people in the worst possible moment. A lifeboat exists for abandonment: it takes a large assigned complement away from a ship being given up. A rescue boat exists for retrieval: a small, fast craft launched by a few crew to pick a person out of the water or shepherd liferafts together. Some vessels nominate one lifeboat to double in the rescue role, but the signs still communicate different intentions to the reader.

The distinction shapes placement too. E036 signs face the flow of evacuees coming from muster stations; a rescue boat position is signed for the trained boat crew who will run to it, often on one side of the ship only. When a passenger reads E036, the expected response is to stop there and follow crew loading instructions — the boat in front of them is the destination, and the craft is boarded at deck level before it ever touches the water.

SOLAS and LSA Code Context

SOLAS Chapter III dictates how many lifeboats a ship carries and how quickly they must be ready, while the LSA Code specifies the craft themselves — construction, engine, capacity, equipment, and release gear. Cargo ships increasingly meet their requirement with a single free-fall lifeboat mounted on a stern ramp, which launches by sliding clear of the ship rather than lowering on davit falls; the same E036 symbol marks it, supplemented by the boarding instructions specific to that installation.

Regular drills keep the sign honest: crews muster, board, and periodically lower and maneuver each boat in the water on the schedule SOLAS prescribes. Numbered boats — odd to starboard, even to port by convention — get supplementary panels alongside the symbol so the muster list assignment matches what people see on deck.

Signing Lifeboat Stations Well

Post E036 at each davit or ramp position and at the embarkation deck access points that serve it, sized for the longest sightline an approaching evacuee will have. On passenger ships the symbol repeats along the embarkation deck so a group arriving from either direction finds its boat; photoluminescent versions keep the station findable if lighting fails during a night abandonment.

Complete the picture with the companion signs: E032 back along the route to the assembly station, E053 at any embarkation ladder serving the position, and E035 where a knife is staged. A lifeboat station that is well signed reads as a sequence, not a single symbol — someone dropped anywhere along the route can orient themselves and keep moving toward the boat without asking anyone.

What is the difference between a lifeboat and a liferaft?

A lifeboat is a rigid, motorized craft launched from davits or a free-fall ramp, boarded at deck level by its full assigned complement. A liferaft is an inflatable craft that either drops into the sea in a canister and inflates there or, in davit-launched versions, inflates at deck level. Lifeboats offer propulsion and stronger protection; rafts provide flexible, distributed capacity. Use E036 for boats and E038 or E039 for rafts.

What does the E036 lifeboat sign look like?

A white pictogram of an occupied boat suspended on launching falls, on the green safe-condition square defined by ISO 3864-1. It appears at lifeboat stowage and embarkation positions, often with a supplementary panel giving the boat number.

Is a free-fall lifeboat marked with the same sign?

Yes. E036 covers the lifeboat regardless of launching method, including stern-mounted free-fall boats on cargo ships. The launching-specific safety instructions — harness use, seating direction, release sequence — are posted separately at the boarding hatch.

Why are lifeboats numbered odd and even?

By long-standing convention, odd numbers go to boats on the starboard side and even numbers to port, counted from forward. The numbering ties each person's muster list assignment to a physical boat, so the number panel next to the E036 symbol is part of the wayfinding, not decoration.
