CLASS 5 – OXIDIZERS & ORGANIC PEROXIDES
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 5 placards identify oxidizing substances and organic peroxides during transport, divided into two TDG categories:
- 5.1 Oxidizers – materials that intensify fire by releasing oxygen
- 5.2 Organic Peroxides – unstable substances that may cause fire, explosion, or rapid decomposition
These placards are required under Transport Canada (TDG) regulations to clearly communicate enhanced fire and reactive hazards to carriers, first responders, and the public.
Essential for safe, compliant transport of oxidizing and reactive materials.
