When it comes to ensuring the well-being of workers and employees in a workplace or establishment, prevention is always better than cure. It not only applies to health but also to how we work. While there are always solutions to injuries and accidents, it is always better to avoid them in the first place.
This is where safety signs and symbols come into play. Understanding these symbols is crucial for maintaining a safe environment, ensuring that everyone, from employees to visitors, is aware of potential hazards and knows how to act in emergencies.
While it might seem minor, safety symbols are essential in giving additional information to people clearly and concisely. This article will discuss safety symbols and their importance and application to the workplace.
What are Safety Symbols?
Safety signs and symbols are recognizable graphic labels that play a pivotal role in communicating safety protocols and instructions in different work-related environments. These symbols are designed to be immediately understandable, using specific shapes, colors, and symbols to convey important information about safety requirements, hazards, and procedures.
Despite the differences in appearance that may exist from one country or region to another, the underlying objective of these signs remains consistent: to provide clear, universal safety guidance that transcends language barriers and can be easily interpreted by individuals worldwide.
This global approach to safety communication ensures that, regardless of where a person is or what language they speak, they can understand and follow the necessary safety precautions to protect themselves and others around them.
Why Use Safety Symbols?
Safety symbols serve as a universal language in the realm of occupational health and safety. These pictures, while not exhaustive in detail, are universally recognized symbols that transcend linguistic barriers. This means that no matter where you’re working—be it in a factory in Asia, a construction site in Europe, or a laboratory in the Americas—you’ll be able to understand the potential hazards you face simply by looking at the posted symbols.
This universality is crucial in creating a safe working environment for everyone, regardless of their native language or familiarity with the site. The implementation of safety symbols as part of occupational health and safety programs is crucial. For instance, the use of a hazardous gas symbol alerts workers to the potential presence of dangerous gasses. In contrast, an additional sign mandating the use of a gas mask provides clear instructions on how to mitigate this hazard.
It’s important to note that while signs and symbols are vital, they are no substitute for comprehensive training. They do, however, serve as critical reminders on the job. This is particularly beneficial for workers who are not familiar with a specific area or process within the workplace. A simple sign bearing a safety symbol can enable workers to quickly identify a potential hazard and make an immediate, informed decision on how to proceed safely.
Types of Safety Symbols
Safety Symbols are categorized into several types, each serving a unique purpose in conveying critical safety information. These types include Prohibition, Warning, Mandatory, and Emergency symbols, each identifiable by distinct features and colors to prompt specific actions or caution. Here, we will explore these categories in detail, outlining key examples to better understand their applications in various environments.
Prohibition
Prohibition symbols are universally recognized signs designed to tell what actions are strictly forbidden in a specific area to ensure safety. These symbols are predominantly characterized by a red circle with a diagonal line through it. Some common examples include:
- No smoking
- No entry
- No drinking water
- Do not touch
- No photography
Warning
Warning symbols signal potential hazards that could harm individuals or property. They are usually triangular with a yellow background and a black border. Examples of warning symbols include:
- General caution
- Electrical hazard
- Slippery surface
- Flammable material
- Toxic material
Mandatory
Mandatory symbols specify actions that must be taken to ensure safety. They are typically depicted as a blue circle with a white pictogram or text. Examples of mandatory safety symbols include:
- Wear safety goggles
- Wear ear protection
- Use hand protection
- Wear a safety harness
- Keep area clean
Emergency
Emergency symbols provide information about emergency exits, first aid, or rescue facilities. These symbols are often green, signifying safety and indicating where emergency resources can be found. Some examples are:
- Emergency exit
- First aid kit
- Emergency shower
- Evacuation assembly point
- Fire extinguisher
Globally Harmonized System (GHS) Pictograms
The Globally Harmonized System (GHS) classifies and labels chemicals according to their specifications. The GHS pictograms are symbols used to indicate the type of hazard a chemical poses. There are nine GHS pictograms (according to Princeton), each representing a different type of hazard. The pictograms are as follows:
- Health hazard: Indicates a harmful chemical if inhaled, ingested, or absorbed through the skin, posing risks to human health.
- Flammability hazard: Used to signal a flammable or combustible chemical that can ignite easily and pose fire hazards.
- Instability hazard: Signals a hazardous chemical that may react violently or explode when exposed to heat, shock, or friction, presenting immediate danger.
- Oxidizing hazard: Indicates a chemical that is an oxidizer, promoting combustion by providing oxygen, potentially leading to fires.
- Corrosive hazard: Signals are corrosive chemicals that can cause severe damage to living tissue, like skin, upon contact, posing serious health risks.
- Toxic hazard: Indicates a poisonous chemical if inhaled, ingested, or absorbed through the skin, with detrimental effects on health.
- Asphyxiation hazard: Signals are chemicals capable of causing asphyxiation by displacing oxygen in the air, threatening respiratory function.
- Biohazard: Indicates a chemical harmful to humans or the environment, highlighting potential biohazards and health risks.
- Radiation hazard: Indicates a radioactive chemical that may be harmful if inhaled, ingested, or absorbed through the skin, with risks associated with radiation exposure.
Tips to Make Your Safety Signs and Symbols More Effective
