Warning: Vehicle Fumes Sign – Ventilation Must Be In Use During Cargo Operations

Vehicle Fumes Warning Sign (IS0004)

This vehicle fumes sign warns crew and vehicle deck personnel that ventilation must be running at all times during cargo operations. On ro-ro vessels and car carriers, engine exhaust builds up quickly in enclosed vehicle decks, and clear warning signage like this helps prevent dangerous fume concentrations before they become a health hazard.

When to Use This Sign

Install this warning at vehicle deck entrances, ramp access points, and anywhere drivers or deck crew might start an engine while the ventilation system is not confirmed running. It is especially important on decks where multiple vehicles idle simultaneously during loading and unloading.

Design and Materials

Manufactured to IMO Resolution A.1116(30) and ISO 24409-2 requirements, this sign uses self-adhesive film (see Materials below) that charges under ambient light and glows for up to ten hours in darkness. The film is waterproof and resistant to saltwater corrosion, making it well suited to exposed vehicle decks, and the peel-and-stick backing allows for quick installation on bulkheads or deck structures.

Installation and Use

Mount the sign at eye level near ramp entrances and deck access points so drivers and crew see the warning before engines are started. Pair it with active ventilation monitoring where possible so the warning is backed by a functioning extraction system.

Compliance and Standards

This sign supports compliance with SOLAS Chapter II-2 requirements for special category spaces and vehicle decks, and IMO guidance on ventilation during cargo operations. Vessel operators should also reference Safe Work Australia’s workplace safety signage guidance when auditing hazard signage fleet-wide.

Fitting Into a Vessel’s Broader Hazard Signage

A vehicle fumes warning works alongside other vehicle deck hazard signage – no smoking notices, fire hose locations, and emergency shutdown points – to form a complete safety system for enclosed vehicle spaces. Consistent placement throughout car decks and ro-ro spaces ensures drivers and crew are never caught unaware.
