Red Comet Fire Extinguisher Grenade Value Guide

The Red Comet Fire Extinguisher Grenade is a fascinating piece of mid-century fire safety history, prized for its vibrant glass and unique spring-loaded steel bracket. These grenades are highly collectible due to their transition from a common household defense to a banned historical curiosity following the discovery of carbon tetrachloride's toxicity.

What Is Red Comet Fire Extinguisher Grenade Worth?

The typical price range for Red Comet Fire Extinguisher Grenade is $75 - $85 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• The presence and condition of the original steel mounting bracket significantly increases the market value.
• Intact original labels and clear, unchipped glass command the highest prices within the $75-$85 range.
• Rarity of the specific model variant, as some Red Comet designs featured different glass shapes or mechanical triggers.
• Completeness of the unit, including the fusible link that acted as the thermal sensor for the spring mechanism.

How to Identify Red Comet Fire Extinguisher Grenade?

• Look for the distinct 'Red Comet' branding embossed on the glass or printed on the original metal wall bracket.
• Verify the presence of the original spring-loaded trigger mechanism which was designed to shatter the glass bulb upon reaching high temperatures.
• Check for the original liquid contents, though many collectors prefer emptied bulbs for safety due to the hazardous nature of carbon tetrachloride.
• Examine the glass for the characteristic bulbous shape and deep red or clear coloration typical of the 1930-1950 production era.

History of Red Comet Fire Extinguisher Grenade

Originating in the late 19th century, these glass grenades became popular in the early 20th century as a first line of defense against household fires. When heat from a fire reached a certain point, a spring-loaded mechanism would shatter the glass, releasing carbon tetrachloride which would smother the flames by displacing oxygen. While clever, they were eventually discontinued due to the toxic fumes produced by the chemical agent when exposed to heat.
