plastic on fire in kitchen... don’t know where else to ask

so i’m stupid and made a dumb mistake. there was melted plastic in my oven and i didn’t realize it. idk how it got there. started to preheat oven to put in a pizza and it caught on fire. I put the fire out and had the windows open for like 6 min as it is freezing outside and can’t let the heat out. it doesn’t smell strongly of melted plastic anymore. i’m going to clean it out of the oven but should I be concerned about the air in my house? like I said I opened the windows for a bit and don’t smell melted plastic anymore. I feel so stupid and stressed :(
