Safety signs in Singapore are a legal requirement across construction sites, factories, warehouses and public buildings. At My First Sign, we produce custom caution signs, warning signs, prohibition signs, and mandatory signs, manufactured with reference to SS 508 for safety colours and safety signs, as well as ISO 7010 international standards. Our signs help support MOM and SCDF compliance by keeping staff, visitors, and contractors clearly informed of workplace hazards.
What Are Caution and Warning Signs?
Caution and warning signs are types of safety signs designed to alert individuals to potential hazards in a specific area. While they serve a similar purpose, there is a distinction between the two. Caution signs indicate a lower-risk hazard that could cause minor or moderate injury if not avoided, such as a wet floor or low ceiling. In contrast, warning signs highlight more serious hazards that could result in severe injury or even death, like high voltage or falling debris zones.
These signs are commonly used in a variety of environments including construction sites, factories, commercial buildings, and public spaces. Examples include signs for wet floors, high voltage areas, construction zones, and slippery stairs.
To ensure clarity and consistency, these signs often incorporate internationally recognised safety symbols, such as those defined by ISO 7010 and ANSI standards. These symbols use specific colours, shapes, and pictograms to quickly communicate danger or precautionary measures, even in multilingual or multicultural settings.
By using proper caution and warning signs, organisations can significantly reduce the risk of accidents and ensure compliance with workplace safety regulations in Singapore and globally.
Types of Caution Signs Offered
At My First Sign, we provide a comprehensive range of Singapore warning signs tailored for diverse environments, especially industrial, commercial, and construction settings. Below are some of the most commonly requested industrial safety signs:
Each of our custom caution signs is available in a variety of durable materials including PVC, aluminium, sticker decals, reflective finishes, and photoluminescent options for low-light visibility.
For enhanced clarity and impact, we can also incorporate internationally recognised symbols and supply corresponding visuals or images upon request.
Construction Site Caution Signs
Alert workers and visitors to potential site hazards such as falling debris or uneven surfaces.
Electrical Hazard Signs
Used to indicate high voltage areas or exposed wiring to prevent electrocution risks.
Chemical & Biohazard Warnings
Essential for labs, factories, and hospitals to signal the presence of hazardous substances.
Slippery Surface Caution
Ideal for areas prone to spills, cleaning, or wet weather, helping prevent slip and fall incidents.
PPE Required Zone Signs
Remind individuals that personal protective equipment is mandatory in designated zones.
Vehicle Movement Warnings
Common in loading bays, warehouses, and construction zones to signal forklift or truck activity.
Where Are These Safety Signs Used in Singapore?
Clear and compliant safety signs play an essential role in maintaining safe environments across multiple industries in Singapore. From high-risk construction zones to public spaces, these signs help communicate hazards, instructions, and regulatory requirements effectively.
Construction Sites
Construction areas in Singapore require visible and durable warning signs to indicate restricted access, mandatory protective equipment, and ongoing works. Proper signage supports BCA site compliance and helps contractors maintain safer working conditions during inspections.
Factories & Warehouses
Industrial facilities rely on clear hazard indicators, directional signs, and operational reminders to minimise risks. Well-placed safety signs assist with MOM safety standards, equipment warnings, and designated loading or forklift zones.
Hospitals & Laboratories
Healthcare and laboratory settings use signage to indicate biohazards, restricted areas, and hygiene protocols. Clear instructions help protect both staff and visitors, especially in high-sensitivity environments where safety compliance is critical.
Public Car Parks & Condominiums
Car parks and residential developments use caution and hazard signs to guide vehicles and pedestrians safely. These signs highlight height limits, slippery floors, or restricted areas, reducing the likelihood of accidents.
Government Facilities
Public buildings and regulated premises require standardised warning signs to ensure clarity and consistency. From emergency exits to restricted zones, compliant signage supports public safety and inspection requirements.
Safety Sign Colour Codes in Singapore
SS 508 and ISO 7010 define four standard colours for safety signs, each with a specific meaning.
Using the correct colour for the intended message is a requirement under SS 508. Placing a mandatory instruction on a yellow triangle instead of a blue circle, for example, is a non-compliant sign that could be flagged during a MOM inspection.
| Colour | Shape | Meaning | Common Examples |
|---|---|---|---|
|
Red |
Circle or square |
Prohibition and fire safety |
No smoking, no entry, fire extinguisher |
|
Yellow |
Triangle |
Warning and caution |
High voltage, slippery floor, falling objects |
|
Blue |
Circle |
Mandatory action |
Wear hard hat, wear safety boots, wear goggles |
|
Green |
Rectangle or square |
Safe condition |
Emergency exit, first aid, evacuation route |
