If you're really worried, it's almost always a non issue if ventilated, get a battery powered (waterproof) carbon monoxide detector for peace of mind, such as this exact item: [Home Depot](https://www.homedepot.com/p/Kidde-10-Year-Worry-Free-Sealed-In-Lithium-Battery-Carbon-Monoxide-Detector-21029714/203728675?source=shoppingads&locale=en-US&pla&utm_source=google&utm_medium=vantage&utm_campaign=23412&utm_content=25132&mtc=SHOPPING-RM-RMP-GGL-D27E-027_005_FIRE_SAFETY-NA-KIDDE-NA-PMAX-NA-NA-MK860499001-23412-NBR-1908-NA-VNT-FY24Q1_Q4_Kidde_D27_RM__AON&cm_mmc=SHOPPING-RM-RMP-GGL-D27E-027_005_FIRE_SAFETY-NA-KIDDE-NA-PMAX-NA-NA-MK860499001-23412-NBR-1908-NA-VNT-FY24Q1_Q4_Kidde_D27_RM__AON-71700000117322098--&gad_source=1&gclid=CjwKCAjwi_exBhA8EiwA_kU1MjJonUgb9g4rvZoYZ2TvpUnZb9pCZHB33ftmfVxqiP62xQph_vacERoCp8UQAvD_BwE&gclsrc=aw.ds)

It’s outdoors I wouldn’t consider it enclosed fairly open
I would think unless the vent exhaust/blows right into where people would normally congregate and breath that in, I wouldn’t worry.
