ASTM F2058 candle warning label: what it must say

ASTM F2058, the Standard Specification for Fire Safety for Candles, defines the cautionary statement that belongs on a candle or its packaging. If you sell candles, this warning is the single most-scrutinized piece of copy on your label.

What ASTM F2058 is

ASTM F2058 is a voluntary consensus standard published by ASTM International that addresses the fire safety of candles. Among other provisions, it prescribes a cautionary statement (a "warning") that communicates the basic fire and burn hazards of an open flame. Although it is a voluntary standard rather than a federal regulation, retailers and marketplaces routinely require compliance, and it reflects the fire-safety expectations the U.S. Consumer Product Safety Commission (CPSC) applies to candles as consumer products.

The three required parts of the warning

A compliant ASTM F2058 cautionary statement combines three elements:

1. The safety-alert symbol — an equilateral triangle enclosing an exclamation mark — placed immediately before the signal word.
2. The signal word WARNING, in a legible, conspicuous size.
3. The standard precautionary statements, which tell the user how to prevent fire and serious injury.

The standard's three core precautionary statements are, in plain language:

• Burn within sight. Never leave a burning candle unattended.
• Keep away from things that catch fire.
• Keep away from children and pets.

Burn-instruction guidance

Beyond those three statements, ASTM F2058 expects practical burn guidance so the consumer can use the candle safely. Common, standard-aligned instructions include burning on a stable, heat-resistant surface, keeping the wax pool clear of matches and wick trimmings, stopping use before the candle burns down to the last portion of wax, and trimming the wick before each lighting.

Placement and legibility

The warning must be legible and conspicuous when the candle is positioned for use. For small candles (votives, tea lights, wax melts) where there is no room on the item itself, the warning may appear on the packaging, a hang tag, or a bottom label. The safety-alert symbol must accompany the signal word; printing only the word "WARNING" without the triangle-and-exclamation symbol is a common mistake.

Wax melts and flame-free products

Wax melts have no open flame of their own but are heated in a warmer, so they still carry burn-hazard and supervision language and should follow the warmer manufacturer's instructions. ASTM F2417 (fire safety for candle accessories) covers the warmers themselves. When in doubt, keep the supervision and keep-away statements.
