Factory safety signs in Malaysia:
a guide to OSHA 1994 and MS 2558
Malaysian factories use safety signs to meet the employer's duty under the Occupational Safety and Health Act 1994 (OSHA 1994) to keep workers informed about hazards. OSHA does not give one fixed list of signs. Instead, the signs you need come from your risk assessment, specific regulations such as those on noise and chemicals, and fire safety rules. The Malaysian Standard MS 2558:2022 sets the colours and design principles that make signs consistent and easy to understand.
Which laws and standards apply to factory signs?
- OSHA 1994 (as amended in 2022). The amendments came into force on 1 June 2024, together with the repeal of the Factories and Machinery Act 1967. OSHA now applies to all places of work in Malaysia. Employers have a general duty to provide a safe workplace and the information and instruction workers need, and safety signs are one of the main ways to do this.
- MS 2558:2022 – Safety and health signage used in the workplace. This Malaysian Standard sets the safety colours and design principles for workplace signs used for incident prevention, fire protection, health hazard information and emergency evacuation. It is widely used together with the international standard ISO 7010.
- OSH (Noise Exposure) Regulations 2019. Areas with excessive noise identified in a noise risk assessment are demarcated as hearing protection zones and marked with signs.
- CLASS Regulations 2013. Hazardous chemicals supplied for use at work must carry GHS labels, and labels and safety data sheets must be in Bahasa Malaysia and English.
- Fire safety rules. The Uniform Building By-Laws 1984 require exit signs, and MS 2687:2018 covers the installation and maintenance of KELUAR sign lighting and emergency lighting.
Safety sign colours and shapes
Using the standard colours and shapes means workers recognise a sign's meaning at a glance, even before reading the text:
- Prohibition – red circle with a diagonal bar. Something you must not do, such as "No smoking" or "No naked flames".
- Mandatory – blue circle. Something you must do, such as "Wear safety helmet" or "Wear hearing protection".
- Warning – yellow triangle with a black border. A hazard to watch out for, such as forklift traffic, high voltage or hot surfaces.
- Safe condition – green square or rectangle. Escape routes, first aid, eyewash stations and the assembly point.
- Fire equipment – red square or rectangle. The location of fire extinguishers, hose reels, fire alarm call points and fire blankets.
Signs a factory typically needs, area by area
Your risk assessment decides the final list, but most factories need signs in these areas:
Entrances and production areas
- Mandatory PPE signs: safety helmet, safety shoes, safety glasses, gloves or high-visibility vest, as required
- "Authorised persons only" signs for restricted areas
- Visitor safety rules at the main entrance
Machinery and maintenance
- Warnings for moving parts, crushing, entanglement and hot surfaces
- "Do not operate" and lockout/tagout tags during maintenance
- Emergency stop markings on machines
Traffic and loading areas
- Forklift and vehicle warning signs
- Speed limit, pedestrian walkway and crossing markings
- Loading bay and overhead crane warnings
Noisy areas
- "Hearing protection zone" and "Wear hearing protection" signs at every entrance to the zones identified in your noise risk assessment
Chemical stores and process areas
- GHS labels on every chemical container, including when chemicals are transferred into smaller containers
- Warning signs for flammable, corrosive or toxic substances at the store entrance
- "No smoking" and "No naked flames" signs
- Eyewash and emergency shower location signs
Electrical areas
- "Danger – high voltage" warnings on switch rooms and electrical panels
- "Authorised persons only" on substations and switch rooms
- Keep the area in front of electrical panels clear and marked
Confined spaces and work at height
- "Danger – confined space, entry by permit only" at tanks, pits and similar spaces
- Fall hazard and "Wear safety harness" signs where work at height takes place
Fire safety and emergency
- Fire extinguisher, hose reel and fire alarm call point signs, placed so equipment can be found even when it is hidden by stock or machines
- KELUAR (exit) signs above exits and directional signs along escape routes, with emergency lighting
- "Fire door – keep closed" signs
- Assembly point sign and an evacuation plan at key locations
- First aid box and AED location signs
Tips for effective safety signs
- Base signs on hazards, not habit. Too many signs cause "sign blindness". Use your risk assessment to decide what is needed.
- Place signs where the decision is made – at the entrance to a zone, at eye level, and in good lighting.
- Use clear pictograms with short text in the languages your workers understand.
- Choose the right material. Use durable, weather-resistant signs outdoors and photoluminescent (glow-in-the-dark) signs on escape routes.
- Keep signs up to date. Replace faded or damaged signs, and review them whenever the layout, machinery or chemicals change.
Quick checklist
- Every hazard in the risk assessment has a matching sign or label
- Signs follow MS 2558 colours and shapes
- Hearing protection zones are marked at every entrance
- All chemical containers carry GHS labels
- Every fire extinguisher, hose reel and call point is signed and visible
- KELUAR signs and emergency lights work, and escape routes are clearly marked
- The assembly point and evacuation plans are displayed
- Signs are clean, readable and not blocked

Frequently asked questions
Does OSHA 1994 list the safety signs a factory must display?
No. OSHA 1994 places a general duty on employers to keep the workplace safe and to give workers the information and instruction they need. Which signs you need depends on the hazards found in your risk assessment. Specific regulations, such as those on noise and hazardous chemicals, and fire safety rules add more specific signage and labelling requirements.
What is MS 2558?
MS 2558:2022 is the Malaysian Standard for safety and health signage used in the workplace. It sets the safety colours and design principles for signs used for incident prevention, fire protection, health hazard information and emergency evacuation.
Do safety signs need to be in Bahasa Malaysia?
Chemical labels and safety data sheets under the CLASS Regulations 2013 must be in both Bahasa Malaysia and English. For other signs, use pictograms with short text in the languages your workers understand, which often means Bahasa Malaysia and English, and other languages where needed.
How often should factory safety signs be checked?
Check them during routine workplace inspections, and review them whenever the layout, machinery, chemicals or processes change, after an incident, and when the risk assessment is updated. Replace signs that are faded, damaged or hidden.
