1-((2,5-DIMETHOXYPHENYL)AZO)-2-NAPHTHOL Air & Water Reactions
Azo dyes can be explosive when suspended in air at specific concentrations. Insoluble in water.

1-((2,5-DIMETHOXYPHENYL)AZO)-2-NAPHTHOL First Aid
EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling poison control center or a hospital.IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness etc) develop.

SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. IMMEDIATELY call a hospital or poison control center even if no symptoms (such as redness etc) develop. IMMEDIATELY transport the victim to a hospital for treatment after washing the affected areas.
