Are candles dangerous?

A candle that meets BS EN 15493 (fire safety) and BS EN 15494 (warning labels), uses a wick and wax tested together, and is poured into a vessel rated for candle use, is safe to burn unattended only within its own warning label. Most fires linked to candles come from unattended burns, drafts, or non-candle vessels. The rules under this hub spell out each safe-use criterion.

Do candles need warning labels?

Yes. In the UK and EU, every candle sold to the public must carry the BS EN 15494 warning pictograms (do not leave unattended, keep away from children and pets, keep away from flammable materials), plus the CLP hazard block for the fragrance allergens it contains. The Waxverse CLP Label Generator produces a compliant label from your recipe.

Are scented candles safe?

Scented candles burned within their tested fragrance load on an IFRA Category 12 fragrance, in a vessel rated for candle use, are safe. The two failure modes are exceeding the wax's maximum fragrance hold (causing weeping and flame flare) and using a non-IFRA-12 fragrance (which may contain allergens above safe limits for candle combustion).

Are candles safe around pets?

Most fragrance oils designed for IFRA Category 12 use are low-risk. The exception is essential oils with terpene profiles cats cannot metabolise (tea tree, pine, citrus, eucalyptus, peppermint). Burn those only in rooms shared with humans. See the pet-safe guide for the full list.
