Class 4.3 labels and placards

Class 4.3 includes substances that react with water to release flammable gases, often with intense heat or explosion risk. Even light moisture, rain or condensation can start a dangerous reaction, threatening workers, vehicles and the environment. These dangerous goods require strict separation from liquids and dry handling procedures throughout the transportation of dangerous goods.

Durable hazard labels and dangerous goods placards provide clear visual warnings for quick recognition and safe planning. Accurate packaging labels improve compliance, prevent mishandling and reduce delays or penalties. Designed for road, rail, sea, inland waterways and air (ADR/RID/IMDG/ADN/IATA), our solutions meet international dangerous goods regulations and support emergency responders in identifying water-reactive substances immediately.
