Particle System - Airlock

Hi, I want to create an airlock type thing that when the doors shut behind the player, some form of gas will flood in (steam particles for example)
I’ve created a trigger box and door that opens when the player presses the E key in the box alongside animations to go with this. Is there any way i would be able to get this to spawn after the animation and to last for a few seconds before fading away? Thanks
