TYPES, MEANINGS, USES AND SELECTION GUIDANCE
Safety signs are a standardised system of visual communication used in South Africa to identify hazards, indicate required actions, communicate prohibitions, and provide emergency information in workplaces and public environments.
Safety signage is about influencing behaviour at the moment risk is encountered.
It is not a paperwork exercise, and it is not solved by signs alone.
SCOPE OF THIS OVERVIEW
This page serves as a comprehensive reference to safety signs used in South Africa. It explains how safety signs are classified, interpreted, selected, and applied in line with recognised South African National Standards and aligned international conventions.
It does not replace site-specific risk assessments, professional safety advice, or formal training.
WHAT ARE SAFETY SIGNS
Safety signs are standardised visual signs used in South Africa to communicate safety information, warn of hazards, indicate required actions, prohibit unsafe behaviour, and identify emergency equipment and escape routes. Their primary purpose is to reduce risk by ensuring that safety information is visible, understood, and acted on quickly at the point where risk is encountered.
Safety signs communicate meaning through a combination of colour, shape, symbols, and wording, allowing messages to be understood consistently, even in environments where language barriers exist or rapid decision-making is required.
In South Africa, safety signs are widely used across workplaces, public buildings, construction sites, factories, warehouses, offices, retail environments, and public infrastructure.
WHAT SAFETY SIGNS ARE DESIGNED TO DO
Safety signs are designed to:
- draw attention to hazards that cannot be completely eliminated
- influence behaviour at the point where risk exists
- provide clear instructions or restrictions
- support safe movement and decision-making
- identify emergency routes, equipment, and facilities
WHY SAFETY SIGNS ARE IMPORTANT
Safety signs play a critical role in reducing the likelihood of injury, damage, and disruption by:
- alerting people to potential hazards
- indicating actions that must or must not be taken
- supporting workplace safety procedures
- improving awareness and consistency
- assisting during emergency situations
Clear and well-placed safety signs help protect employees, contractors, visitors, and members of the public by communicating essential safety information quickly and unambiguously.
SAFETY SIGNS AND WORKPLACE SAFETY IN SOUTH AFRICA
In South Africa, employers and site managers have a general responsibility to provide a safe working environment, which includes identifying hazards and communicating residual risks where they cannot be eliminated through other controls. Safety signs are commonly used to support this responsibility by helping to identify hazards, guide behaviour, and indicate emergency equipment and escape routes.
Safety signage does not remove risk on its own. Instead, it supports safety management by making hazards visible and reinforcing safe behaviour.
SAFETY SIGN STANDARDS IN SOUTH AFRICA
In South Africa, safety sign designs follow South African National Standards (SANS), administered by the South African Bureau of Standards (SABS), and align closely with ISO 7010 and ISO 3864-3 conventions for safety sign colours, shapes, and symbols.
South African National Standards (SANS), administered through the South African Bureau of Standards (SABS), provide guidance on the appearance and use of safety signs to promote uniform understanding across different environments and industries. These standards align closely with widely recognised international safety sign conventions.
While standards help ensure consistency and recognition, safety signage on its own does not address risk. Correct sign selection, placement, and maintenance form part of a broader safety approach that includes risk assessment, training, and appropriate safety controls.
This overview is intended to provide general guidance on safety signage principles and does not replace site-specific safety assessments or professional advice.
Common mistakes in safety signage include overuse, poor placement, and relying on signs to compensate for unmanaged hazards. More signs do not necessarily mean safer environments.
COMMON ENVIRONMENTS WHERE SAFETY SIGNS ARE USED
Safety signs are commonly found in:
- industrial and manufacturing facilities
- construction sites
- warehouses and logistics centres
- offices and commercial buildings
- hospitals and healthcare facilities
- schools and universities
- retail centres and shopping malls
- public infrastructure and transport areas
SAFETY SIGN COLOURS AND SHAPES
Symbolic safety signs use recognised colour and shape conventions defined by safety sign standards to communicate meaning quickly and consistently, even before any text is read.
COLOUR MEANINGS
Safety sign colours are standardised to ensure immediate recognition and consistent interpretation across different environments.
Square or rectangular (red) – fire-fighting signs |
Circular (red with diagonal line) – prohibitory signs |
Triangular (yellow) – warning signs |
Circular (blue) – mandatory signs |
Square or rectangular (green) – emergency and safe condition signs |
- Red – prohibition signs and fire-fighting equipment
- Yellow – warning signs indicating potential hazards
- Blue – mandatory signs indicating required actions
- Green – emergency and safe condition signs, including escape routes and first-aid facilities
SHAPE MEANINGS
- Triangular – warning signs
- Circular (blue) – mandatory signs
- Circular (red with diagonal line) – prohibitory signs
- Square or rectangular – emergency, fire-fighting, or information signs
By combining colour and shape, safety signs convey critical information even before any text is read.
HOW SAFETY SIGN CATEGORIES DIFFER
Each safety sign category serves a specific function within a standardised safety communication system:
- warning signs highlight potential danger
- mandatory signs instruct required behaviour
- prohibitory signs prevent unsafe actions
- fire signs identify fire-related equipment and locations
- emergency signs indicate safe routes and facilities
- information signs support general awareness
MAIN SAFETY SIGN CATEGORIES
FIRE FIGHTING SIGNS (FB)
Fire-fighting signs are used to identify the location of fire-fighting equipment, fire alarms, and fire-related safety facilities so they can be found quickly in an emergency.
HAZARD WARNING SIGNS (WW)
Hazard warning signs are used to alert people to potential hazards or dangerous conditions that may cause injury or harm if not avoided.
MANDATORY SIGNS (MV)
Mandatory signs indicate actions that must be followed to comply with safety requirements and reduce risk in a specific area or activity.
PROHIBITORY SIGNS (PV)
Prohibitory signs are used to indicate actions or behaviours that are not permitted because they may create or increase risk.
GENERAL INFORMATION SIGNS (GA)
General information signs provide non-hazard safety information, directions, or site-related guidance to support safe movement and awareness.
PHOTOLUMINESCENT SIGNS
Photoluminescent signs are designed to remain visible in low-light or power-failure conditions by emitting stored light to support safe evacuation and emergency response.
HOW TO CHOOSE THE RIGHT SAFETY SIGN
When selecting safety signage, consider:
- the type of hazard or information being communicated
- who will be exposed to the sign
- viewing distance and visibility requirements
- lighting conditions
- indoor or outdoor placement
- material durability and mounting surface
QUICK GUIDANCE FOR SIGN SELECTION
- If a hazard exists but cannot be removed, a warning sign is typically used
- If an action must be taken to remain safe, a mandatory sign is used
- If an action creates risk, a prohibitory sign is used
- If equipment must be located quickly in an emergency, fire or emergency signs are used
PLACEMENT AND VISIBILITY CONSIDERATIONS
Safety signs should be:
- visible before a hazard is encountered, allowing time to react
- positioned at an appropriate eye level for the people using the area
- placed along normal routes of movement and entry points
- unobstructed by equipment, stock, doors, or structures
- suitable for the lighting conditions, including low-light or emergency situations
- kept clean, legible, and in good condition
Correct placement ensures that safety signs are noticed, understood, and acted upon at the right moment.
ARE SAFETY SIGNS LEGALLY REQUIRED IN SOUTH AFRICA
Safety signs are commonly used to support workplace safety responsibilities. While signage alone does not ensure compliance, it plays an important role in hazard communication and risk awareness as part of an overall safety approach.
