Question RED.P and time

[Pajmon]

Hi, does anyone have experience with red phosphorus and whether it loses its effectiveness over time, or something happens to it in the air. what does the humidity of the air do to it... Thank you for any answer

"Freshly prepared, bright red phosphorus is highly reactive and ignites at about 300 °C (573 K). After prolonged heating or storage, the color darkens; the resulting product is more stable and does not spontaneously ignite in air," according to wikipedia :] additionally, humid storage conditions can cause the release of phosphine (which is toxic). try using a dehumidifier maybe?
