Key Takeaways

P&FM Basics & Exemption Thresholds are only the starting point for deciding whether fuel, paint, or gas storage needs approval. The material’s classification, total quantity, container, location, and use all matter.

• Exemption thresholds depend on the type and hazard classification of the material.
• Separate containers may still need to be assessed as one aggregate quantity.
• Exempt storage remains subject to ordinary fire-safety and housekeeping duties.
• LPG, aerosols, thinners, and mixed-use products need careful label and SDS review.
• Unclear or borderline arrangements should be confirmed with SCDF or a qualified professional.

Understanding SCDF P&FM basics

Petroleum and flammable materials are not limited to petrol cans. The category can include fuels, solvents, coatings, aerosols, LPG, and other products that can ignite or support a fire. For a builder, contractor, owner, or MCST, the practical question is not simply what a product is called, but how it behaves and how it is stored. This guide explains the assessment in plain terms, while the Fire Code 2023 should be consulted for the wider fire-safety framework.

What petroleum and flammable materials (P&FM) include

P&FM commonly covers petroleum products and materials that present a fire or explosion hazard because they are flammable. Petrol and diesel are familiar examples, but a workshop may also hold paints, varnishes, cleaning solvents, adhesives, gas cylinders, or pressurised aerosols. A product used only occasionally can still affect the compliance assessment when it remains on the premises.

The starting point is a current safety data sheet, product label, and inventory record. Those documents help identify the material’s physical state, flash point, flammable ingredients, and recommended storage conditions. If the information is incomplete, do not assume the product is harmless because it is sold for ordinary household or construction use.

How SCDF classifies flammable liquids, solids, and gases

Classification separates materials by their physical form and fire behaviour. Flammable liquids may release vapour that ignites readily, while flammable solids can burn, melt, or generate combustible dust. Flammable gases, including LPG, can form an ignitable mixture with air and may create pressure hazards when containers are heated.

The precise category must come from the applicable SCDF requirements and the product’s technical information. A colour, trade name, or familiar use is not a substitute for classification. Where a product has several hazards, the more demanding storage control may become relevant.

Why storage quantity, concentration, and container type matter

Two products with similar names may create different obligations because their flammable content, concentration, or container differs. A concentrated solvent in a metal can is not assessed in exactly the same way as a diluted coating in a small retail container. Packaging can also affect leakage, vapour release, and the way a fire develops.

Quantity should therefore be recorded using the measure required for the applicable rule, rather than an informal count of tins or bottles. Keep the original packaging details, maximum container capacity, and whether containers are open, connected, or being used during operations.

The difference between storing, handling, and transporting P&FM

Storage concerns keeping materials at a premises, whether in a cabinet, room, tank, yard, or work area. Handling includes dispensing, mixing, transferring, using, or opening a container. Transport concerns moving the material, including movement connected with delivery or site operations. These activities can trigger different controls, so a storage exemption should not be treated as a general permission to handle or transport the same quantity without review.

A project may involve all three activities at once. For example, diesel may arrive by vehicle, remain in a tank, and then be dispensed into equipment. The assessment should describe the complete arrangement rather than considering only the final container.

How P&FM exemption thresholds work

An exemption threshold is a boundary below which a particular storage arrangement may not require a P&FM storage licence, subject to the exact material and conditions. It is not a universal number for every flammable product. The safest approach is to identify the classification first, then compare the total quantity and storage arrangement with the applicable SCDF table or requirement.

What an exemption threshold means under SCDF requirements

The threshold is a regulatory screening point, not a certificate that a premises is safe in every respect. If the quantity and conditions fall within an exemption, licensing may not be required for that specific arrangement. The operator must still prevent ignition, control spills, keep access and escape routes clear, and store materials in suitable containers.

Thresholds should be checked against the maximum quantity reasonably present, not just the amount visible on the day of an inspection. Seasonal deliveries, project peaks, and unopened backup stock can all change the result.

How thresholds differ by material class and hazard category

A small quantity of one material may be treated differently from the same volume of another. Flammable liquid, combustible liquid, flammable solid, and flammable gas categories have distinct hazards and may use different units or limits. The relevant information may also depend on concentration, flash point, container size, and whether the product is connected to equipment.

Do not copy a threshold from a general online summary and apply it to every product. A useful review records the product, classification, quantity unit, storage location, and source of the applicable limit. This makes the conclusion easier to verify and update.

When multiple products must be counted as an aggregate quantity

Mixed storage is where many apparently simple assessments go wrong. Several compatible or similar products may need to be counted together, especially when they share a hazard category or are kept within the same storage area. The fact that each individual can is below a perceived limit does not necessarily mean the combined stock is exempt.

A simple inventory table can expose the issue early. It should include routine stock, reserve stock, waste awaiting disposal, partly used containers, and materials temporarily moved from another area. The total should reflect the maximum credible quantity, not an optimistic average.

Material group	Information to record	Why it matters
Fuels	Product, total volume, tank or container type	Determines the relevant fuel assessment
Paints and solvents	Flammable content, container size, total stock	Helps distinguish products within the same work area
LPG and gases	Cylinder capacity, number, connection status	Supports an aggregate gas quantity review
Aerosols	Propellant and product classification	Pressurised containers can add a separate hazard

The table is a working aid, not a replacement for the governing requirement. After grouping the stock, compare each group with the correct threshold and then review the physical layout. The total quantity matters, but so do ignition sources, ventilation, separation, and access.

Why exemptions do not remove general fire-safety duties

An exempt quantity still needs sensible controls. Containers should be sound, closed when not in use, protected from heat and impact, and kept away from ignition sources. Spills must be dealt with promptly, and workers should know what to do if a container leaks or a fire starts.

For larger workplaces, emergency planning should match the actual hazards and staffing arrangements. A company may also consider the SCDF-related CERT programme when establishing an organised emergency response capability. That is a separate preparedness matter, not a substitute for checking the storage threshold.

Checking whether your fuel storage is exempt

Fuel storage is often introduced as a practical necessity: equipment needs diesel, vehicles need petrol, or a generator requires a dedicated supply. Practical necessity does not remove the need for a regulatory review. The answer depends on fuel type, maximum quantity, tank or container design, dispensing method, and where the fuel sits within the premises.

Common examples of diesel, petrol, and other fuel storage

Diesel may be kept in a day tank, mobile equipment tank, drum, or fixed installation. Petrol may be stored in approved portable containers or in a purpose-designed tank. Other fuels, including mixtures and specialty products, require their own classification rather than being assumed to follow diesel or petrol treatment.

Record the capacity of each tank and container, including connected pipework where the applicable rule calls for it. Also identify fuel held inside machinery, spare containers in a store, and stock awaiting use. These details help distinguish operational fuel from a genuinely small incidental quantity.

How to assess fuel containers, tanks, and dispensing areas

Inspect the whole arrangement, not just the container label. Ask whether the tank is fixed or mobile, whether it is protected against vehicle impact, how dispensing occurs, and whether vapour or spills could reach an ignition source. A tank that is acceptable in an outdoor compound may be unsuitable in an enclosed plant room.

The dispensing area deserves particular attention. Keep hoses, nozzles, electrical equipment, drains, and housekeeping arrangements under review. The SCDF P&FM storage licensing guide can provide useful background, but the actual site conditions still need to be matched to the applicable requirements.

Situations where workplace fuel storage may require a licence

A licence may become relevant when the quantity exceeds the applicable exemption, when a fixed tank or dispensing system creates a regulated arrangement, or when fuel is stored as part of a commercial operation. Construction sites, logistics yards, workshops, and industrial premises should be especially careful when stock changes frequently.

Do not wait until installation is complete to ask the question. Regulatory submissions and approvals can affect tank location, access, fire protection, and building works. Early review is usually easier than retrofitting a non-compliant fuel area.

Red flags that can invalidate an apparent exemption

An apparent exemption can fail when the inventory excludes reserve stock, connected tanks, waste fuel, or containers kept in another nearby room. It can also fail when a product has been misclassified or when the storage arrangement does not meet the conditions attached to the threshold.

Other warning signs include open containers, unlabelled drums, blocked access, fuel stored beside hot work, and a dispensing point placed in a poorly ventilated area. Treat these as corrective actions even if the calculated quantity appears low.

Assessing paints, solvents, and chemical products

Paint and chemical storage is common in renovation, construction, manufacturing, retail, and property maintenance. The difficulty is that a shelf may hold water-based paint beside solvent-based coatings, thinners, cleaners, adhesives, and aerosols. A visual count alone cannot establish whether the collection falls within an exemption.

Which paints and coatings may qualify as P&FM

Some paints, lacquers, varnishes, primers, and coatings contain flammable solvents and may fall within P&FM controls. Others are water-based or have different hazard properties. The product’s SDS and label should identify the relevant hazards, but the documents need to be current and matched to the exact product formulation.

Store products according to their hazards rather than arranging them only by colour, brand, or project. A small workshop cabinet can become a regulated quantity when several projects contribute leftover tins and replacement stock.

How flammable liquid content affects classification

The flammable liquid content can change how a mixed product is treated. A paint with a low solvent content may present a different risk from a concentrated thinner, even if both are used with the same brush or spray system. Flash point and other technical information can be decisive.

When the SDS gives a range or the label and SDS appear inconsistent, preserve both documents and ask the supplier for clarification. Do not select the less demanding classification simply because it produces a convenient storage result.

Counting products stored in workshops, warehouses, and retail areas

Count stock across the areas that form part of the same operational assessment. That may include a workshop, warehouse, sales floor, preparation room, and temporary staging area. Moving tins from the storeroom to the workbench does not necessarily remove them from the premises’ total quantity.

A good stock procedure identifies an owner, a review date, and a maximum permitted quantity for each area. It should also cover returned goods, damaged packaging, and waste awaiting collection. These categories are easily overlooked during routine purchasing.

Special considerations for aerosols, thinners, and mixed-use products

Aerosols combine a product with a pressurised propellant, creating both flammability and container-pressure concerns. Thinners and cleaning solvents may be more volatile than the coatings they support. Mixed-use products can be particularly confusing when the same item is used for maintenance, retail sale, and production.

Keep aerosols away from heat and physical damage, and separate incompatible products where the SDS requires it. If a product is decanted, mixed, or used in a spray process, assess that activity separately from unopened storage.

Understanding gas and LPG storage limits

Gas storage requires a more careful review because a leak can spread through a room and find an ignition source some distance away. LPG cylinders also remain pressurised, and their location, orientation, protection, and connections matter. A count of cylinders is useful, but it is not the entire assessment.

How SCDF treats LPG cylinders and flammable gas containers

LPG cylinders and other flammable gas containers should be treated according to their gas classification, capacity, condition, and intended use. Full, partly full, and connected cylinders may all need to be considered. Empty cylinders should not automatically be ignored because residual vapour may remain.

Use approved containers and keep them upright and secured against falling or impact. The storage location should be assessed for ventilation, heat exposure, vehicle movement, and access by unauthorised people.

Calculating quantities across cylinders, tanks, and connected systems

Begin with the capacity and number of cylinders or tanks, then identify which are connected to appliances or process equipment. The applicable calculation may use a specified capacity or quantity measure, so avoid converting figures casually. A connected manifold or reserve bank can change the overall arrangement even when only one appliance is operating.

Keep a diagram or simple register showing cylinder locations, connections, and replacement stock. This is not a Financial Mathematics Exam calculation; it is a hazard and inventory review that must use the correct SCDF method.

Storage requirements for indoor and outdoor gas areas

Indoor gas areas need suitable ventilation, protection from ignition sources, and clear access. Outdoor areas still require control: cylinders should be protected from weather and impact without being enclosed in a way that traps leaking gas. Separation from incompatible materials and building openings may also be relevant.

The surroundings should be reviewed whenever the building layout changes. A new wall, loading bay, exhaust outlet, or air intake can alter how a previously acceptable gas store performs in practice.

When gas usage, refilling, or commercial supply changes the compliance position

Using gas for a small appliance is not the same as refilling cylinders, distributing gas, or supplying multiple customers. Refilling and commercial supply introduce additional operational and regulatory questions beyond simple storage. The quantity may also increase through reserve cylinders and delivery stock.

Describe what happens on site, who handles the cylinders, and how they arrive and leave. If the activity is expanding, obtain confirmation before increasing capacity or adding a manifold. A storage conclusion based on domestic-scale use may not fit a commercial operation.

Applying the thresholds to real-world storage arrangements

A threshold review is strongest when it is treated as a site assessment rather than a desk exercise. Draw the boundaries of the premises, list every relevant product, and note where each item is stored or used. This is the point at which engineering, architectural, and operational details come together.

A step-by-step method for reviewing your inventory

Start by collecting SDSs, labels, purchase records, tank data, and cylinder registers. Then walk through the premises and compare the documents with what is physically present. Record the maximum quantity, not merely the usual quantity, and separate storage from active use.

A practical review can follow this sequence:

1. Identify each product and its physical and hazard classification.
2. Record maximum quantity, container type, and exact storage location.
3. Group materials where the applicable rule requires aggregate counting.
4. Compare each group with the relevant exemption threshold and conditions.
5. Document uncertainties, corrective actions, and any confirmation sought.

This sequence creates an auditable trail and makes changes easier to manage. It also prevents a purchase order or temporary project stock from quietly altering the compliance position.

Worked examples for fuel, paint, and gas storage

Suppose a workshop has diesel in a fixed tank, petrol in portable containers, solvent-based paint in a cabinet, and LPG cylinders outside. The correct assessment is not one grand container count. Each material must first be classified, then assessed under the relevant rule, while any required aggregate quantities are calculated within the proper category.

A second example is a retail renovation store holding unopened paint, aerosol cleaners, and thinners. Even if the products are distributed across two rooms, the operator should establish whether they are part of one premises inventory and whether the storage conditions satisfy the exemption. A third example is a restaurant adding reserve LPG cylinders; the reserve stock and connected system should be reviewed together rather than considering only the cylinder attached to the appliance.

How location, occupancy, and building use affect the assessment

The same quantity can present a different practical risk in a detached outdoor store, a basement, a high-rise commercial unit, or a crowded workshop. Occupancy, escape routes, ventilation, fire compartmentation, vehicle movement, and nearby ignition sources all influence the safety assessment. Building alterations can therefore affect P&FM compliance even when the inventory stays constant.

For projects involving design changes or regulatory submissions, Stellar Structures provides engineering, architectural, and interior design solutions, including regulatory submissions and approvals. Any professional review should still be based on the actual products, quantities, and site arrangement.

What to do when safety data sheets and labels provide conflicting information

Pause the assessment when the SDS, label, technical data sheet, and purchase description do not agree. Check the product code and revision date first; documents for a similar product are not good enough. Ask the supplier or manufacturer to confirm the classification in writing and retain the response with the inventory record.

If the conflict affects a threshold or storage design, do not proceed on the more convenient assumption. A qualified fire-safety professional or SCDF confirmation may be appropriate before the material is brought onto the site.

Meeting SCDF licensing and fire-safety requirements

Licensing is only one part of a compliant arrangement. The storage area must also be designed, operated, and maintained so that foreseeable leaks, ignition, access, and emergency conditions are controlled. For owners and project teams, the best time to resolve these issues is before procurement and installation.

When to apply for a P&FM storage licence

Apply for a licence when the quantity or arrangement falls outside the applicable exemption, or when the activity involves a regulated storage installation. The need may arise from fixed tanks, commercial stock, larger cylinder banks, or a change in use. Confirm the current process and submission requirements with SCDF rather than relying on an old approval or a previous tenant’s arrangement.

A licence assessment may require drawings, product information, storage details, and supporting fire-safety information. Keep the submission aligned with the final installation; changing the tank location or increasing capacity after approval can create a new issue.

Key storage controls for cabinets, rooms, tanks, and cylinders

Controls depend on the material and the facility, but commonly include suitable containers, secure access, ventilation, separation from ignition sources, impact protection, and clear escape routes. Cabinets and rooms should not become informal dumping areas for unrelated chemicals. Tanks and cylinders need inspection, connection control, and protection appropriate to their location.

The design should account for normal operations as well as delivery, maintenance, leakage, and emergency response. If workers must carry containers through occupied areas, that movement should be included in the risk review.

Records, signage, separation, and emergency equipment to maintain

Maintain a current chemical inventory, SDS set, inspection record, training record, and register of tanks or cylinders. Signage should identify hazards and restrictions clearly, while separation should follow the requirements for incompatible materials. Emergency equipment must be accessible, suitable for the hazards, and kept clear of stored stock.

Records are most useful when someone is responsible for updating them after a purchase, disposal, relocation, or process change. A quarterly review is a reasonable management practice, although higher-risk operations may need more frequent checks.

How to prepare for inspections and correct non-compliant storage

Before an inspection, walk the route an inspector would take from the entrance to the storage and work areas. Check labels, quantities, access, housekeeping, ventilation, emergency equipment, and the consistency between the inventory and the physical stock. Photographing the arrangement can help track corrective work, but photographs do not replace technical records.

If non-compliance is found, isolate the immediate hazard, stop adding stock, and create a dated correction plan. Relocate, dispose of, or redesign the arrangement only in a way that remains safe and properly documented.

Avoiding costly P&FM compliance mistakes

Most avoidable problems arise from incomplete information rather than deliberate disregard. A business may inherit containers, add project stock, or change a room’s use without revisiting its original assessment. A short, repeatable review process is more dependable than relying on memory.

Relying on product names instead of hazard classifications

Trade names such as cleaner, coating, fuel treatment, or degreaser say little about the regulatory outcome. Two products with the same everyday description can have different flash points, ingredients, and container hazards. Always connect the product name to the exact SDS and label.

If the product changes formulation, the old assessment may no longer apply. Procurement teams should make technical documentation part of the approval process before ordering unfamiliar chemicals.

Treating each container separately instead of calculating total quantities

Counting one can, one cylinder, or one drum at a time can create a misleading result. The relevant question is often how much of a material or hazard category exists across the premises. Include connected systems, reserve stock, waste, and temporary storage where applicable.

Keep a running total when stock changes frequently. A spreadsheet or register is sufficient for many sites, provided it reflects reality and identifies the person responsible for updates.

Assuming small quantities are automatically exempt

Small quantities can still be unsafe when stored beside heat, in a blocked corridor, or in unsuitable packaging. An exemption may depend on conditions as well as quantity, and those conditions can be breached by poor housekeeping or an unsuitable location.

Treat the threshold as one part of the assessment. Fire prevention, worker information, spill response, and emergency access remain necessary even when a licence is not required.

Storing incompatible materials together

Flammable liquids, oxidising products, corrosives, gases, and reactive chemicals should not be grouped merely because they fit on the same shelf. A leak, fire, or damaged container can turn incompatible storage into a larger incident. Consult the SDS and separate materials according to the hazards identified there.

Keep the storage plan understandable to the people who use it. A clear layout, labelled zones, and controlled access reduce the chance that a new delivery will be placed in the wrong area.

When to seek confirmation from SCDF or a qualified fire-safety professional

Seek advice when the classification is uncertain, quantities are near a threshold, several hazard categories are mixed, or a tank, manifold, dispensing point, or commercial supply arrangement is involved. The same applies when a building alteration changes ventilation, compartmentation, occupancy, or escape routes.

Stellar Structures offers a one-stop service from initial design to regulatory submissions and approvals, with engineering, architectural, and interior design solutions. Its role should be described accurately: the site team still needs to provide complete product and inventory information, and SCDF remains the relevant authority for SCDF requirements.

Conclusion

P&FM exemption thresholds are useful screening tools, but they do not reduce a complex storage arrangement to a single number. Classify every product, calculate quantities honestly, review the physical layout, and obtain confirmation when the facts do not fit neatly within an exemption. That approach gives owners, contractors, and operators a clearer basis for safe storage and sound regulatory decisions.

Frequently Asked Questions

What does P&FM mean?

P&FM means petroleum and flammable materials. It can include fuels, flammable liquids, certain paints and solvents, aerosols, flammable solids, LPG, and other materials identified by their hazard properties.

Does staying below an exemption threshold mean no safety controls are needed?

No. An exemption may remove a licensing requirement for a particular arrangement, but general fire-safety duties still apply. Containers, ignition sources, ventilation, access, housekeeping, and emergency arrangements must remain suitable.

Should separate fuel containers be added together?

They may need to be assessed as an aggregate quantity, depending on the material category and applicable requirement. Include reserve stock, connected containers, and other relevant fuel held on the premises.

Are all paints treated as P&FM?

No. Paints and coatings differ in their ingredients and fire properties. Review the exact product label and SDS, including flammable liquid content and flash point, rather than relying on the word “paint.”

Do empty LPG cylinders count in a storage review?

They should not automatically be excluded. Empty cylinders can retain residual vapour and may still require safe storage. Confirm how the applicable requirement treats empty or returned cylinders.

Can a previous tenant’s licence cover a new operator?

Do not assume that it can. A change in operator, product, quantity, layout, or use may affect the approval position. Verify the current licence conditions and premises arrangement before relying on an existing document.

Who should review an uncertain storage arrangement?

Start with the current SCDF requirements and product documentation, then seek confirmation from SCDF or a qualified fire-safety professional when classification, aggregate quantity, or site conditions are unclear.
