CLASS 4 PLACARDS

CLASS 4 PLACARDS –
Available in durable tagboard or adhesive-backed vinyl:

 Tagboard – designed for use with standard placard holders on trucks and containers
 Adhesive Vinyl – peel-and-stick option for direct application to surfaces

Class 4 placards identify flammable solids and other reactive materials during transport, divided into three TDG
categories:
 4.1 Flammable Solids – materials that ignite easily through friction, heat, or sparks
 4.2 Spontaneously Combustible – substances that can self-heat and ignite in air
 4.3 Water-Reactive Substances – materials that emit flammable gases when in contact with water
These placards are required under Transport Canada (TDG) regulations to clearly communicate fire and reactivity
hazards to carriers, first responders, and the public.
Essential for safe, compliant transport of reactive and flammable solid materials.
