R-32 dehumidifiers are usually safe for mechanical rooms and crawlspaces if you take basic safety steps. Since R-32 can catch fire easily, don’t let it near flames or sparks. Ensure good airflow, and keep service panels clear. Like any dehumidifier, give the unit enough space in small areas and don’t block the airflow.
