A lifeboat ( liferaft) is a small, rigid or inflatable watercraft carried for emergency evacuation in the event of a disaster aboard ship. Inflatable lifeboats may be equipped with auto-inflation ( carbon dioxide or nitrogen) canisters or mechanical pumps. A quick release and pressure release mechanism is fitted on ships so that the canister or pump automatically inflates the lifeboat, and the lifeboat breaks free of the sinking vessel. Commercial aircraft are also required to carry auto-inflating life rafts in case of an emergency water landing, and are also kept on offshore platform
