TT Club’s Quick Reference Guide For Toxic & Infectious Substances
We recently covered the TT Club’s new quick-reference guide on the safe handling of flammable liquids, and as a continuation of that series we are now highlighting their key practices to follow – and avoid – when dealing with Toxic & Infectious Substances – or Class 6 dangerous goods.
Recognised globally, TT Club is a leading insurer and risk management specialist serving the international transport and logistics sector.
Class 6 dangerous goods include substances that are toxic or infectious, posing severe risks such as property damage, cargo damage, injury, environmental harm, insurance invalidation, and potential criminal prosecution.
- 6.1 Toxic substances: Cause serious or fatal injury if inhaled, swallowed, or in contact with skin. Examples: Cyanide, cadmium, arsenic, lead.
- 6.2 Infectious substances: Contain pathogens that can harm the host. Examples: Ebola, clinical waste, Lassa fever, HIV/AIDS.
