Flammable Liquid 3 Sign

A flammable liquid sign is used to warn of liquids that can ignite easily and present a fire risk if exposed to heat, sparks, or open flames. 

This sign highlights areas where flammable liquids are stored, handled, or used, helping people recognise the hazard before entering or working nearby.

At Foamex Printing Company, we supply flammable liquid sign options designed to communicate this warning clearly using recognised layouts and high-contrast printing. 

These signs support clear hazard communication in the workplace and shared environments where flammable liquids may be present.

Types of Flammable Liquid Hazard Signs

Different warning formats may be used depending on how flammable liquid risks need to be communicated in a given environment.

  • Flammable Liquid Sign: Used to identify the presence of liquids that can ignite easily and require careful handling.
  • Flammable Liquid Placard: Displays the same flammable liquid warning in a placard-style format where a more prominent visual is required.
  • Flammable Liquid 3 Sign: Commonly used to indicate flammable liquids classified under Class 3 hazard warnings.

In areas where general flammability risks also apply, a flammable sign may be displayed alongside flammable liquid warnings. 

Materials, Printing, and Finish Options for Flammable Liquid Signs

Our flammable liquid sign products are produced using rigid Foamex board, selected for its lightweight structure and clean finish. 

This material suits environments where warning signs need to remain visible and intact during everyday use.

The material performs well in both indoor and outdoor settings, helping maintain the appearance and readability of the sign over time. 

High-contrast printing ensures the text and symbols remain easy to see, allowing the flammable liquid warning to be recognised quickly without additional explanation.

Available material, fixing, and finish options include:

  • Self-adhesive backing or pre-drilled mounting holes
  • Multiple standard-size options
  • High-contrast printing for improved visibility
  • Matt, gloss, or dry-wipe finishes
  • Optional photoluminescent finish for low-light areas
  • Layout adjustments depending on placement requirements

These options allow flammable liquid sign formats to be adapted to different environments while keeping the warning consistent and recognisable.

Many organisations also refer to general health and safety regulations when determining how flammable liquid warnings are displayed alongside other safety signage.

UK Compliance Requirements for Flammable Liquid Signs

UK regulations require flammable liquid signs to clearly communicate risks associated with flammable substances in workplaces and public environments. 

These signs must comply with UK health and safety legislation, including COSHH and CLP regulations, and use recognised colours, shapes, and pictograms to ensure hazards are easily understood.

A flammable liquid sign is used to meet legal requirements for identifying liquids that may ignite during handling, storage, or use. 

With correct placement and visibility, flammable hazard signage supports immediate recognition and effective risk communication. Where substances pose an elevated fire risk, a Highly Flammable sign may also be used to reinforce the warning.

20 Reviews for Flammable Liquid Sign - DS16

Aleka Aspinall October 4, 2026

Fifth order from Foamex Printing Company for hazard warning signs. The quality of the flammable liquid signs is the same as everything else in the range — consistent, well produced, reliable.

Adrie Allsopp September 5, 2026

These have been in place for six months in a warm, busy environment. The yellow hasn't faded and the print is still sharp. Good material for a sign that needs to remain legible long-term.

Airic Aldred August 22, 2026

The ordering process was simple and the proof showed clearly what we were getting before production started. Good process for safety-critical signage.

Bennet Adger July 3, 2026

These signs are well made and have survived a winter in the workshop without any deterioration.

Avery Bardell June 1, 2026

The anti-tamper design mentioned in the product description is genuinely useful in our environment we had issues with signs being moved or damaged in other parts of the site. These have stayed firmly in place.

Bellamy Bellingham May 13, 2026

Had a specific requirement for a custom size to fit an awkward space near our chemical storage racking. The custom sizing was accommodated without any fuss and the sign fits the space perfectly.
