04 · Handling and storage
Storing and handling Naled
Storage conditions
Keep container tightly closed in a dry and well-ventilated place. Recommended storage temperature 2 - 8 °C. Storage class (TRGS 510): Non-combustible, acute toxic Cat.3 / toxic hazardous materials or hazardous materials causing chronic effects.

Incompatible materials
Incompatible materials: Strong oxidizing agents
Source: Hazardous Substances Data Bank (HSDB)
Reactivity
NALED is incompatible with the following: Strong oxidizers, acids, sunlight, water [Note: Corrosive to metals. Hydrolyzed in presence of water.] (NIOSH, 2024). Unstable in presence of Iron (USCG, 1999). Organophosphates are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
