ISO 9094:2022

Overview

ISO 9094:2022 - Small craft - Fire protection specifies a practical level of fire prevention and protection intended to give occupants enough time to escape a fire on board small craft. The standard applies to small craft with a hull length (LH) up to 24 m (excluding personal watercraft). It focuses on life safety, reducing fire spread, and providing viable escape means; it explicitly excludes permanently installed liquid‑fuel galley stove design (see ISO 14895:2016) and carbon monoxide detection systems (see ISO 12133). The second edition updates definitions, escape‑route guidance, engine‑compartment requirements, and fire‑extinguisher placement.

Key topics and technical requirements

ISO 9094:2022 covers practical, safety‑oriented requirements rather than component design details. Major topics include:

• Fire prevention
  • Safe installation and positioning of cooking/heating appliances (including pitch/heel considerations such as a 15° pitch guideline to prevent stove sliding)
  • Materials and protective measures for zones near open flames, radiant heaters, solid‑fuel and electrical appliances
  • Requirements for engine, fuel and exhaust compartments (fixed and portable petrol systems)
  • Electrical installation ignition protection and decklight safety
  • Liquefied Petroleum Gas (LPG) system provisions, including propulsion and non‑propulsion uses
• Fire detection
  • Guidance on detection to ensure timely occupant warning
• Fire escape
  • Layout of escape routes, minimum clear dimensions and fire‑exit operation (including deck hatch provisions and watertightness)
• Fire‑fighting equipment
  • Location, type and capacity guidance for portable fire extinguishers (including CO₂ types)
  • Selection, installation and activation criteria for fixed fire‑extinguishing systems
  • Engine compartment protection, fire ports, and fire blankets
• Information and documentation
  • Displayed safety information and owner’s manual content requirements (normative Annex A and informative annexes on extinguisher selection)

Practical applications and who uses it

ISO 9094:2022 is intended for:

• Boat designers and small craft manufacturers integrating fire‑safety measures
• Marine system installers and electricians working on propulsion, LPG or electrical systems
• Surveyors, certification bodies and flag administrations assessing small craft safety compliance
• Manufacturers of portable and fixed fire‑extinguishing equipment targeting the recreational and small commercial craft market
• Owners/operators seeking to understand minimum escape, detection and equipment expectations

The standard helps reduce fire risk, guide safe layout and equipment placement, and support consistent safety documentation for vessel owners.
