The key to formaldehyde storage lies in ventilation, the use of adsorption and decomposition materials, and understanding that its release is affected by temperature and humidity. Stored formaldehyde solutions must be sealed and protected from light, with a small amount of methanol added to prevent polymerization. It is important to note that formaldehyde is a toxic chemical and laboratory safety regulations must be strictly followed to avoid contact with humans and environmental pollution.
