01 / FIRE EXTINGUISHER TYPES
MS 1182:2017 · MS 1539 · eFEIS · workplace selection & procurement
Quick answer: ABC dry powder is commonly used for mixed Class A, B and C hazards; CO₂ is often selected around energised electrical and sensitive electronic equipment; foam is generally used for suitable Class A and B hazards; water is mainly for Class A materials; and wet chemical is designed for Class F cooking-oil and fat fires. The correct extinguisher is determined by the fuel, fire rating, electrical conditions, approved fire-safety requirements and exact product markings not by cylinder colour alone.

02 / MALAYSIA FIRE CLASSES
Malaysia's current MS 1182:2017 - Classification of fires classifies fires according to the nature of the fuel. One of the most common online mistakes is importing the US convention and calling electrical fires “Class C”. Under the Malaysian classification, Class C means flammable gases; energised electrical equipment is an additional hazard that affects safe agent selection.
| Class / hazard | Fuel / example | Selection implication |
|---|---|---|
| Class A | Wood, paper, textiles, packaging and many ordinary combustible solids. | Water, foam, powder or another specifically rated agent may be suitable. |
| Class B | Flammable / combustible liquids and liquefiable solids. | Foam, powder, CO₂ or another agent must match the actual liquid and rating. |
| Class C | Flammable gases such as LPG, propane or butane. | Agent selection must be coordinated with safe isolation of the gas supply and the site's emergency plan. |
| Class D | Combustible metals such as magnesium or reactive metal powders. | Requires metal-specific extinguishing media; ordinary ABC powder is not a general Class D solution. |
| Class F | High-temperature cooking oils and fats. | Wet chemical is the primary portable-extinguisher category associated with this hazard. |
| Electrical hazard | Energised switchboards, servers, motors, panels and equipment. | Not a separate Malaysian fire class; verify the agent's electrical suitability and underlying fuel. |
Primary standard: Department of Standards Malaysia, MS 1182:2017.
03 / QUICK COMPARISON
| Type | Typical application | Main advantage | Key limitation |
|---|---|---|---|
| ABC dry powder | Mixed Class A, B and C hazards where the exact product carries the required ratings. | Broad mixed-hazard coverage. | Residue can contaminate electronics, clean areas and food environments. |
| CO₂ | Selected Class B hazards and energised electrical / electronic equipment. | No powder or foam residue. | Limited cooling; not a universal solution for deep-seated solid fires. |
| Foam | Suitable Class A and compatible Class B hazards. | Cooling plus a blanket over many liquid surfaces. | Compatibility with the liquid, electrical conditions and foam formulation must be checked. |
| Water / water-based | Mainly Class A materials. | Strong cooling on ordinary combustible solids. | Conventional water is unsuitable for energised electrical equipment, cooking oils and many liquid / reactive hazards. |
| Wet chemical | Class F cooking-oil and fat hazards. | Designed for high-temperature cooking-oil incidents. | Not a general substitute for industrial mixed-hazard extinguishers. |
| Class D media | Specific combustible metals. | Specialist metal-fire control. | The media must be matched to the actual metal; do not generalise across all reactive metals. |
04 / WORKPLACE SELECTION
Most workplaces need a combination because the fire risk changes from one room or process to another. Use the table as a procurement starting point-not a substitute for approved plans or competent assessment.
| Area | Typical hazard | Selection direction |
|---|---|---|
| General office | Paper, furniture, small electrical equipment. | Class A coverage plus an electrically appropriate clean agent near meaningful electrical risk. |
| Server / IT room | Energised electronics, cable insulation and sensitive equipment. | CO₂ is commonly used as portable first-response protection; critical rooms may require designed fixed suppression. |
| Factory / workshop | Mixed solids, liquids, gas, machinery and electrical panels. | Usually a combination of extinguisher types matched to defined zones. |
| Warehouse | Packaging, stored commodities, batteries, chemicals or flammable products. | Select from the actual commodity and fire-load assessment rather than assuming one ABC unit solves every hazard. |
| Commercial kitchen | Hot cooking oils / fats, gas and electrical appliances. | Wet chemical for the Class F hazard, with other protection selected for adjacent risks. |
| Construction site | Changing work fronts, hot work, temporary electrics, fuels and gases. | Review provision as the project changes; locate suitable units for current activities and hazards. |
High-value buying insight: asking “Which extinguisher is best?” is usually the wrong question. The better question is “Which extinguisher is appropriate for this specific hazard area, fire rating and approved building / project requirement?”
05 / ELECTRICAL & SPECIAL HAZARDS
CO₂ is widely selected around energised electrical and sensitive electronic equipment because it leaves no powder or foam residue. But “electrical fire” does not describe the underlying burning material. Cable insulation, plastics and nearby combustibles can continue burning or re-ignite, so power isolation and the wider fire strategy remain important.
Verify the portable agent and rating alongside electrical isolation, access and the building's approved fire-safety system.
Consider contamination risk and whether a fixed clean-agent / inert-gas system is required for the critical space.
A broad-coverage powder extinguisher may create unacceptable secondary contamination even when its fire rating covers the fuel.
Wind, weather and access can affect portable-agent selection and placement; use the site-specific assessment.
Commercial kitchens: Class F cooking-oil hazards generally call for wet chemical protection. A fire blanket can be useful for an appropriate small contained fire, but it is not a substitute for the specified Class F extinguisher or fixed kitchen suppression where required.
Combustible metals: use specialist Class D media selected for the exact metal. Ordinary ABC powder should not be treated as a general metal-fire extinguisher.
Lithium-ion batteries: avoid forcing battery incidents into a simple A/B/C/F decision. Battery chemistry, size, state of charge, enclosure and propagation risk can change the required prevention and response strategy. Significant battery storage or energy-storage systems need a separate assessment.
06 / LABELS & RATINGS
Common identification uses cream for foam, blue for dry powder, black for CO₂ and yellow for wet chemical. Water is generally identified without a contrasting agent band. Always read the agent name, fire-class symbols and rating on the actual extinguisher.

08 / STANDARDS, eFEIS & SERVICING
The extinguisher itself, its selection / placement and its maintenance are different compliance questions. Procurement teams should keep these layers separate.

09 / BUYING MISTAKES & RFQ
Under Malaysia's MS 1182 classification, Class C refers to flammable gases.
The fire rating, agent and hazard matter more than capacity alone.
Broad coverage can come with unacceptable contamination around electronics, food or clean environments.
Commercial cooking-oil hazards need a suitable Class F strategy rather than a generic extinguisher.
Request the exact standard, model-specific documentation and maintenance / eFEIS requirement.
Know who will inspect, service, recharge or replace the units and what records the premises must retain.
Send the complete schedule, BOQ or inspection finding to Haisar for an itemised quotation.
10 / FAQ, SOURCES & INTERNAL LINKS
No. Under MS 1182:2017, Class C refers to flammable gases. Energised electrical equipment is an additional hazard that affects safe agent selection.
No. It provides broad coverage but can create heavy residue and contamination. Sensitive electronics, food areas, clean rooms and specialist hazards may require another agent.
CO₂ is commonly selected because it leaves no powder or foam residue, but the underlying fuel, product rating, room conditions and approved fire strategy still matter.
Wet chemical is the portable-extinguisher category associated with Class F cooking-oil and fat fires. Verify the exact product rating and kitchen protection requirements.
There is no single universal number for every workplace. Quantity and placement depend on the fire rating, hazards, occupancy, travel distance, building layout, approved plans and applicable standards.
Haisar supports equipment sourcing and procurement. Premises certification and regulated installation, testing, servicing, recharging or repair must be handled by the appropriate authority / registered party where required.
