The UN3475 placard identifies a load of ethanol and gasoline mixture with more than 10% ethanol, a class 3 flammable liquid, on tank trucks delivering high-ethanol fuels. It shows the number 3475 in black in its white box, the flame symbol and the class number 3, on a red 10-3/4 X 10-3/4 in diamond that fits most placard holders. Made in Canada, it is sold individually.

Ethanol-gasoline mixtures in transport and storage: what to do in case of a spill

UN number 3475 corresponds to the shipping name ETHANOL AND GASOLINE MIXTURE, with more than 10% ethanol, class 3, packing group II. It is found in the distribution of high-ethanol fuels, such as E85; the exact proportion is on the product documents. Transport Canada's 2024 Emergency Response Guidebook (ERG) places it under guide 127, for flammable liquids that mix with water: its vapours are highly flammable and can cause explosion and flashback, and contact or inhalation can irritate or cause dizziness.

In case of a spill during transport or in your storage area, guide 127 calls for dialing 911, then the emergency number on the shipping document, and isolating at least 50 m around the leak. Eliminate all ignition sources (cigarettes, road flares, sparks, flames), ground the handling equipment, do not touch the product and, if you can do it without risk, stop the leak. Keep the fuel out of waterways, sewers, basements and confined areas. Absorb or cover the liquid with dry earth, sand or another non-combustible material, then transfer it into containers with clean non-sparking tools. For a large spill, dike far ahead of the liquid and consider an initial evacuation of 300 m downwind.

Keep a mineral absorbent (ABGMM225) in the vehicle and near the storage area to cover the liquid, along with chemical socks (ABCB30) and pads (ABCT100) to contain the flow; check their compatibility with the product's safety data sheet.

Fire safety for ethanol-gasoline: which extinguisher to keep in the vehicle and at the warehouse

For a small fire, guide 127 names dry chemical and CO₂ among the extinguishing agents: an ABC dry chemical (EXABC10) extinguisher or a CO₂ (EXCO10) unit is therefore the right choice. Place it in the vehicle cab and at an accessible spot near the storage area, outside the hazard zone. A large fire is a job for firefighters. If a tank, rail tank car or highway tank is involved in a fire, the guide calls for isolating 800 m in all directions and considering an initial evacuation over the same distance.

These guidelines from the 2024 ERG help you prepare your transport and storage procedures. For the exact product and the real situation, the current safety data sheet and the ERG prevail; emergency measures are for trained and equipped personnel, with a positive pressure self-contained breathing apparatus (SCBA), as the guide specifies.

UN3475 placard applications

The UN3475 placard is intended for fuel distributors, service station operators offering high-ethanol fuels and carriers delivering them by tank. Cardboard is handy for a one-time load, rigid plastic is reused from one trip to the next, and self-adhesive vinyl stays in place on a tank dedicated to these fuels.

Complete your display with an aluminum flip chart placard, with five (ECLAP5) legends including class 3, or fourteen (ECLAP14) legends, for trucks whose cargo changes; the class 3 placard with a blank (ECLA3UN) UN box, to write in a number yourself; the class 3 flammable liquid placard (ECLA3); and the yellow and black warning tape (ECT751JN108) to mark off the storage area.

UN3475 placard technical specifications

Placard installation and care

Apply the self-adhesive vinyl to a clean, dry surface. Keep the placard clean so the number stays legible, and replace it if it is damaged, faded or illegible. For a placard exposed to the weather for a long time, choose rigid plastic or vinyl over cardboard.

FAQ: UN3475 placard and ethanol-gasoline transport

Which material should I choose for the UN3475 placard: cardboard, plastic or vinyl?

Cardboard is the low-cost option for temporary use. Rigid plastic is weatherproof and reusable. Self-adhesive vinyl suits permanent application on a tank or trailer.

Does gasoline with 10% ethanol carry UN3475?

No. UN3475 covers mixtures with more than 10% ethanol. Gasoline with 10% or less falls under entry UN1203, according to the applicable criteria.

What safety perimeter is needed for a spill of the fuel?

Guide 127 of the 2024 ERG calls for isolating at least 50 m around the leak. For a large spill, consider an evacuation of 300 m downwind, and 800 m in all directions if a tank is on fire.

Which extinguisher should I keep in a vehicle carrying the fuel?

For a small fire, an ABC or BC dry chemical extinguisher, or a CO₂ extinguisher. A large fire is a job for firefighters: move away and dial 911.

Does the UN3475 placard fit in a placard holder?

Yes. Its 10-3/4 X 10-3/4 in format is the standard size that fits most placard holders.

Suggestions for transport and storage of ethanol-gasoline

For the driver or handler who deals with the fuel at loading, delivery or in the warehouse, plan for Centurion splash goggles (YG454), a 6000 series full face respirator (R6800) with organic vapour cartridges (R60921), selected according to the SDS and the risk assessment, 18 in nitrile gloves (GL37185), waterproof PVC steel toe boots (VC18821C) and a flame-resistant high-visibility vest (VV510FR) to stay visible on the road and at the loading station.

To contain and respond to a spill, keep sheets (ABCT100) and snakes (ABCB30) for corrosive or hazardous chemicals close at hand, a universal mini spill kit for truckers (ABUV) in a resealable bag, to keep in the truck, Magic Monkey mineral granules (ABGMM225), a 10 lb ABC dry chem (EXABC10) extinguisher or a 10 lb dioxide (EXCO10) unit, and 28 in traffic cones (EPTCONE28B) to mark off the perimeter. For a driver working in isolation: the type 1 personal (TR01) first aid kit suits an isolated worker with no access to another kit, a vehicle with 1 to 5 workers, or a vehicle with more than 5 workers less than 30 minutes from medical services; for a vehicle with more than 5 workers more than 30 minutes from medical services, provide the type 2 basic (TR02M) first aid kit. Complete the truck's equipment with a portable road safety kit (TR16) and the set of three removable reflectors (EPTR) to signal a stopped vehicle.
