The season

Don't wait for day light savings.Check your smoke detectors and CO/CO2 detectors. Every sleeping room and @15 ft from a heating source. If you see or smell people using kerosene heaters call 311.@ detectors cost 5-8 bucks at most stores. No cash ask your landlord.

Just a note, kerosene heaters aren't big in NYC. Most people use electric. Easier to find as they are available in every 99 cent store, hardware, and discount store.

Nevertheless, your warning is appriciated.
