Hazard warning labels are a critical part of product safety. Whether indicating corrosive substances, toxic chemicals or flammable materials – these labels are designed to prevent harm. But for blind and visually impaired individuals, traditional visual labels may be inaccessible – posing a serious risk at home, at work, and in public settings.

This article explores why hazard warnings must be made accessible, what is currently in place, and what more needs to be done.

The Problem: When Visual Information Isn’t Enough

According to the World Health Organization, over 43 million people globally are blind, with a further 250 million experiencing moderate to severe visual impairment. Yet most hazard labels rely solely on colour, text, and symbols – making them ineffective for those who cannot see them.

This lack of accessibility increases the risk of:

  • Accidental exposure to harmful chemicals
  • Injury in the workplace due to unrecognised hazards
  • Dependency on others for everyday safety

When hazard communication excludes blind people, it compromises their autonomy, dignity, and safety.

Existing Solutions: What’s Being Done?

1. Tactile Warning Symbols

In the UK and across the EU, many hazardous products (particularly cleaning agents) must include a raised tactile warning symbol (usually an equilateral triangle) to signal danger. These are helpful, but only offer a general alert rather than specifying the type of hazard (e.g., flammable, corrosive, toxic).

2. Braille Labelling

Some pharmaceutical products and a handful of consumer items include braille to indicate product names or key warnings. While this is a positive step, braille remains far from standard across most hazardous goods.

3. Digital Tools and Assistive Apps

Smartphone-based apps such as Seeing AI and Be My Eyes allow blind users to scan items and receive verbal descriptions of text and labels. Some products are starting to feature QR codes or NFC chips that link to accessible safety data.

However, these tools depend on technology access and may not be suitable in all environments, especially in urgent or industrial situations.

Barriers to Better Accessibility

Despite encouraging developments, several challenges remain:

  • Lack of regulation: While tactile symbols are required on certain goods, braille labelling and digital alternatives are not widely mandated.
  • Design limitations: Packaging changes require investment and adaptation in manufacturing processes.
  • Awareness gap: Many designers, producers and policymakers are unaware that current hazard labelling can exclude blind users entirely.

What Should Be Done?

A more inclusive approach to hazard labelling must consider both universal safety and equal access. The following steps are strongly recommended:

-Introduce Standardised Tactile Symbols for Specific Hazards

Instead of a single triangle for all risks, tactile symbols could be developed to distinguish between flammable, toxic, corrosive, and other hazard types.

-Make Braille Labelling Mandatory for Key Products

Essential information such as product name and core warning should be included in Grade 2 (contracted) braille, particularly on cleaning agents, industrial chemicals, and pharmaceuticals.

-Promote Digital Accessibility

Embedding QR codes or NFC tags that link to screen-reader-friendly safety instructions can bridge the gap for many users.

-Provide Training and Guidance to Industry

Regulators and trade bodies should issue clear guidelines and toolkits for incorporating accessible labelling into product design and manufacturing workflows.

First-hand Perspective

Ellie T., a blind mother of two in Manchester, explains how the current lack of accessible warnings affects daily life:

“I label my cleaning products in braille at home, but when I buy something new, there’s no way of knowing it’s hazardous without help. One mistake could be serious- especially with kids around. A tactile warning or braille label would make such a difference.”

A Shared Responsibility

Safety should never depend on sight alone. Hazard warning systems that exclude blind and visually impaired people are not only inequitable – they’re unsafe. As technology evolves and awareness grows, the opportunity to build truly inclusive safety standards has never been greater.

Now is the time to embed accessibility into product safety, not as an afterthought but as a basic requirement.
