In every industry, workplace safety is of the utmost importance. Especially in critical sectors where employees contend with diverse hazards, dangerous chemicals, extreme temperatures, and beyond. To safeguard the well-being of workers amongst these challenges, employers must adopt rigorous safety protocols and procedures.
A fundamental aspect of maintaining a safe work environment is the deployment of safety signs. These visual markers play a pivotal role in signalling potential hazards to workers while furnishing vital instructions on avoiding mishaps and injuries. In this blog post, we delve into the importance of workplace safety signs and explore the psychology behind their design and impact on employees.
The power of visual communication
Humans are highly visual beings. We process visual information faster than text and are more likely to retain and act upon what we see.
In fact, research shows that the human brain processes images 60,000 times faster than text, and 90% of all information transmitted to the brain is visual.
Workplace safety signs leverage this inherent human trait to communicate vital messages quickly and effectively. Here's why visual communication matters in the context of workplace safety signs:
- Immediate understanding: Visual communication is a universal language. Regardless of a person's native language or literacy level, images and symbols can convey meaning almost instantly. For example, a red circle with a slash through it over an image of an open flame communicates "No Open Flames" clearly, even to someone who may not understand the words themselves. This immediate understanding is crucial in emergency situations where every second counts.
- Rapid processing: The human brain is wired to process visual information at lightning speed. This rapid processing is particularly important in the context of safety signs because it allows individuals to react swiftly to potential hazards. For example, when a person sees a "Slippery When Wet" sign with a graphic of a person slipping, their brain quickly registers the message, prompting them to exercise caution.
- Retention and recall: Visual information is more likely to be retained and recalled compared to text-based information. This phenomenon is often referred to as the "picture superiority effect." Simply put, people tend to remember images and symbols better than words. When employees encounter safety signs with strong visual elements regularly, they are more likely to remember safety protocols and guidelines, leading to safer behaviour in the long run.
- Reduced cognitive load: Safety signs reduce the cognitive load on individuals. In complex work environments, employees may be bombarded with various tasks and information. Safety signs simplify the communication of safety instructions by presenting them in a format that requires minimal cognitive effort to understand. For instance, instead of reading a paragraph about the location of fire extinguishers, a simple pictogram of a fire extinguisher with an arrow pointing the way conveys the same information, but in a more efficient and easier-to-digest way.
- Universal applicability: Visual communication through safety signs also transcends cultural and language barriers. In workplaces with diverse populations, safety signs with clear, universally understood symbols and colours ensure that everyone receives the same safety message. This inclusivity is vital for maintaining consistent safety standards across the organisation.
