Description
FIREBLOCK FFG is an advanced, non-toxic, and biodegradable fire suppression gel engineered to deliver superior firefighting performance across a wide range of applications. Its thick, adhesive formulation clings to both vertical and horizontal surfaces, including wood, metal, rubber, plastics, and textiles, forming a protective barrier that cools, smothers, and isolates heat sources.
By combining rapid temperature reduction, oxygen exclusion, and heat encapsulation, FIREBLOCK FFG achieves faster knockdown and enhanced prevention of re-ignition compared to conventional firefighting agents such as water and Dry Chemical Powder (DCP). Its superior cooling capacity allows effective control of deep-seated and smouldering fires, making it ideal for highrisk scenarios such as:
· Tyre and vehicle fires · Recycling and waste stockpiles · Industrial hazards and machinery fires · Structural and commercial fire incidents
Unlike DCP, FIREBLOCK FFG is non-corrosive and environmentally responsible, making it safe for use around equipment, electronics, vehicles, and infrastructure. The gel is premixed with deionized water at the factory, ensuring consistent performance, reliability, and a shelf life of up to five years.
FIREBLOCK FFG is versatile and suitable for multiple deployment methods, including:
· Portable extinguishers (9 L, 25 L, 50 L) · Mobile response units · Pump-and-tank systems · Fixed sprinkler installations · Drone and aerial spraying for fire prevention or suppression
The product is 10× more effective than water, providing long-lasting protection and residual cooling even in challenging fire scenarios. Its gel formulation clings to hot and vertical surfaces, preventing drip-off and ensuring continuous fire suppression.
With FIREBLOCK FFG, emergency services, industrial operators, and commercial facilities gain a safe, environmentally friendly, and highly effective fire protection solution capable of handling both active fires and preventive applications, delivering peace of mind and superior fire safety wherever it is deployed.

FIREBLOCK FFG USES

Risk / Scenario

FFG Advantage

Brake & Tyre Fires

Instantly cools overheated parts to stop ignition; prevents re-ignition

Vertical / Hardto-Reach Surfaces

Gel clings and stays in place even under heat, vibration, or gravity

Multiple DCPs

One FFG extinguisher can

Usually Required replace several DCP units

Fire Prevention (not just suppression)
Frequent Use on Vehicles
Sprinkler System Activation

Spray on hot components before visible flames to prevent ignition
Non-corrosive, safe for regular application on metals, rubber, wiring
FFG can complement or replace water in high-risk areas; adheres to surfaces to provide residual protection

Recycling / Waste Plants

Gel suppresses fires in combustible waste, plastics, and shredded materials; reduces dust and smoke

Application
Residue & Cleanup

Use like any other extinguisher; keep an additional 9 L FFG extinguisher for rapid response
Leaves minimal gel residue; rinses off easily with water

DCP (Dry Chemical Powder) Comparison Powder may extinguish flames but does not cool surfaces; risk of reignition remains Powder falls off quickly; limited effect on vertical surfaces Often multiple DCPs needed to achieve the same effect
Not possible; DCP only acts on active fires
Powder may corrode metals and damage wiring
DCP cannot integrate into sprinkler systems; powder disperses rapidly, no residual protection Powder may suppress flames but does not prevent re-ignition; high dust levels increase visibility hazards
Standard DCP procedure
Leaves corrosive powder; requires deep cleaning

INSTRUCTIONS FOR USE
1. Use of Fireblock FFG Portable Extinguisher Fireblock FFG extinguishers are operated in the same manner as conventional water or foam fire extinguishers. No special technique or additional training is required beyond standard extinguisher use procedures. Always follow the instructions printed on the extinguisher label and your site fire safety protocols. Standard Operating Steps (PASS Method)
P — Pull the safety pin A — Aim the nozzle at the base of the fire S — Squeeze the handle to discharge S — Sweep side to side across the base of the flames
Procedure 1. Approach the fire from upwind where possible 2. Maintain a safe exit route at all times 3. Aim at the base (fuel source), not the flames 4. Apply FFG in controlled sweeping motions 5. Continue application until the fire is fully extinguished and cooled 6. Monitor for re-ignition

INSTRUCTIONS FOR USE
2. Use of Fireblock FFG Through Pump Systems When applied through pumps, hose reels, fire units, or vehicle-mounted systems, Fireblock FFG is used the same way as standard water-based firefighting operations. The primary difference is improved cooling, encapsulation, and knockdown performance.
Key Principle Attack the source of the fire, not the flames. FFG must be directed onto the burning material to: · Cool the fuel · Penetrate surfaces · Suppress vapours · Prevent re-ignition
Pump Application Steps 1. Charge hose line as normal 2. Select spray or jet pattern appropriate to the fire 3. Advance safely toward the fire 4. Apply directly to the base and seat of the fire 5. Work methodically from front to back 6. Continue application until complete cooling is achieved 7. Overhaul and check for hotspots Apply directly here NOT into flames

INSTRUCTIONS FOR USE
3. Application Guidance
DO Aim at the base of the fire Use steady, controlled application Ensure full coverage of burning material Continue cooling after flame knockdown
DO NOT Spray only at flames Use short bursts that do not reach the fuel Stop immediately after flames disappear Dilute FFG unless specifically instructed
4. Operational Notes
· Compatible with standard firefighting equipment · No special pumps or nozzles required · Effective on Class A and applicable mixed-risk fires · Reduced water usage compared to water-only attack · Faster knockdown and improved cooling performance
