to let escape
🕊️ のがす sounds like no gas: release it so the gas leaks out and escapes
逃 = 辶 (walk radical) + 兆. 逃す is the causative of 逃げる (to escape), so it means to make something get away, or to let it go free.
逃 — 辶 walk radical + 兆 zhào (phonetic)
逃 is a semantic-phonetic compound. The walking radical 辶 carries the meaning of motion or going, while 兆 supplies the sound. Together they convey the idea of moving away, hence 'to flee' or 'to escape'.
