The UN2794 placard identifies a load of batteries filled with liquid acid electrolyte, such as lead-acid batteries, class 8 corrosive substances, on battery delivery trucks and collection and recycling vehicles. It shows the number 2794 in black in its white box, the corrosive symbol and the class number 8, on a white and black 10-3/4 X 10-3/4 in diamond that fits most placard holders. Made in Canada, it is sold individually.

Lead-acid batteries in transport and storage: what to do in case of a leak

UN number 2794 corresponds to the shipping name BATTERIES, WET, FILLED WITH ACID, electric storage, class 8. These include lead-acid batteries for vehicles, equipment and backup power systems, not lithium-ion batteries. Transport Canada's 2024 Emergency Response Guidebook (ERG) places them under guide 154, for non-combustible toxic or corrosive substances: the electrolyte can cause corrosive burns and contaminate waterways, a corrosive in contact with metals can release flammable hydrogen, and heated containers can rupture.

In case of a spill during transport or in your storage area, guide 154 calls for dialing 911, then the emergency number on the shipping document, and isolating at least 50 m around a liquid spill, increasing the protected area downwind as needed. Eliminate all ignition sources, do not touch damaged containers or the spilled product without appropriate protective clothing and, if you can do it without risk, stop the leak. Keep the electrolyte out of waterways, sewers, basements and confined areas. Absorb or cover the liquid with dry earth, sand or another non-combustible material, transfer it into containers and keep water out of the containers.

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 wet acid batteries: which extinguisher to keep in the vehicle and at the warehouse

The electrolyte does not burn, but heat can break it down into corrosive or toxic gases. In a fire, it is often the vehicle, the packaging or nearby goods that burn, and heat can rupture containers and release corrosive or toxic gases. For both small and large fires, guide 154 names dry chemical and CO₂ among the agents: an ABC dry chemical (EXABC10) extinguisher or a CO₂ (EXCO10) unit is suitable. Place it in the vehicle cab and at an accessible spot near the storage area, outside the hazard zone. A fire that spreads is a job for firefighters; if a tank is involved, 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.

UN2794 placard applications

The UN2794 placard is intended for battery distributors, heavy vehicle shops, collectors and recyclers carrying new or used lead-acid batteries. 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 truck dedicated to batteries.

Complete your display with an aluminum flip chart placard, with five (ECLAP5) legends including class 8, or fourteen (ECLAP14) legends, for trucks whose cargo changes; the class 8 corrosive placard (ECLA8); and the yellow and black warning tape (ECT751JN108) to mark off the storage area.

UN2794 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: UN2794 placard and wet acid batteries transport

Which material should I choose for the UN2794 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 the UN2794 placard apply to lithium batteries?

No. UN2794 covers batteries filled with liquid acid electrolyte, such as lead-acid. Lithium-ion batteries have their own UN numbers, and the ERG then refers to guide 147.

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

Guide 154 of the 2024 ERG calls for isolating at least 50 m around a liquid spill and increasing the protected area downwind as needed. If a tank is on fire, isolate 800 m in all directions.

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

An ABC or BC dry chemical extinguisher, or a CO₂ extinguisher: guide 154 names them for both small and large fires. A fire that spreads is a job for firefighters.

Does the UN2794 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 wet acid batteries

For the driver or handler who deals with the batteries 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, a hooded Tychem 2000 disposable coverall (VQC127SYL), 12 in Chemstop neoprene gloves (GNE3030), 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 on hand sheets (ABCT100) for corrosive or hazardous chemicals, snakes (ABCB30) for these chemicals, a large 55 US gallon hazmat spill overpack (ABCE55), Magic Monkey mineral granules (ABGMM225), a 10 lb ABC dry powder (EXABC10) extinguisher, a 10 lb BC-rated (EXCO10) extinguisher 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.
