Why Your Tank Cleaning Chemical is a Fire Hazard (And What to Use Instead)
You’ve seen it happen. A crew is cleaning a storage tank, and the chemical they’re using has a flash point low enough to make everyone on site nervous. One spark. One hot surface. One guy who didn’t read the SDS. That’s all it takes.
Most tank cleaning chemicals on the market are hydrocarbon-based solvents. They work. But they’re also flammable. And when you’re working inside or around a vessel that’s had crude, condensate, or refined product sitting in it — flammable is the last thing you want.
The Torch Test Nobody Talks About
We started doing something at Hasten Cleanse that made people uncomfortable at first.
We take our product and the competitor’s product. We add gasoline to both. Then we put a torch to each one.
Theirs lights up. Ours doesn’t.
That’s not a lab trick. That’s the reality of what you’re putting inside your tanks and around your crews every day. The chemical you’re using right now — would it pass that test?
Why Most Companies Haven’t Switched
We hear it constantly: “We’ve been using the same product for years.” Fair enough. Nobody wants to change a process that works, especially on a refinery floor where every change means paperwork, retraining, and risk.
But here’s the question: does your current product actually work better, or is it just what you’ve always used?
When we run Hasten Cleanse against conventional tank cleaners, here’s what happens:
- 80% reduction in downtime. The cleaning cycle is faster because our chemistry bonds to hydrocarbon particles and breaks them down more efficiently. Less time cleaning means your tank is back in service sooner.
- 50% less wastewater generated. That’s not just an environmental win — that’s a disposal cost you’re cutting in half.
- Zero flammability risk. Water-based. Non-hazardous. Non-corrosive. Your crews can work without hot work permits in most cases.
What Hasten Cleanse Actually Does
Hasten Cleanse is a water-based, non-hazardous cleaning chemistry built specifically for oil and gas applications. It uses fatty acids and surfactants — no bacteria, no microbes, no harsh solvents.
When it contacts hydrocarbons, it rapidly bonds to the particles and suppresses vaporization by raising the flash point. That’s why it doesn’t ignite. The chemistry physically prevents it.
It works in:
- Crude oil storage tanks
- Refined product tanks
- Pressure vessels
- Process piping
- Spill situations on soil or water
And it’s fully TSCA compliant and biodegradable. When the job is done, you’re not dealing with hazardous waste disposal.
The Real Cost of Doing Nothing
Your current product might be cheaper per gallon. But factor in:
- Longer cleaning cycles = more downtime = lost production revenue
- More wastewater = higher disposal costs
- Flammability risk = potential for an incident that costs millions
- OSHA exposure = if an inspector walks your site during a cleaning job with a flammable solvent, that’s a finding
The cheapest chemical on the shelf is rarely the cheapest solution.
See It For Yourself
We don’t ask anyone to take our word for it. We show up with our product and yours, and we run them side by side. If Hasten Cleanse doesn’t outperform what you’re currently using, you owe us nothing.
That’s a standing offer. No contract, no commitment. Just a demonstration.

Understanding Flash Point — And Why It Matters More Than You Think
Every cleaning chemical has a flash point listed on its Safety Data Sheet. That number tells you the lowest temperature at which the liquid produces enough vapor to ignite in the presence of an ignition source.
Most petroleum-based tank cleaning solvents have flash points between 100°F and 140°F. That sounds safe until you realize what’s actually happening inside the tank you’re cleaning:
- Ambient temperature inside a tank in Houston in July easily exceeds 120°F. Your cleaning chemical is already at or near its flash point before you even apply it.
- Hydrocarbon residue on tank walls is releasing its own vapors. When you add a solvent with its own flammable vapors to an environment already producing flammable vapors, you’re compounding the risk.
- Agitation, pressure washing, and circulation generate heat. The mechanical energy of the cleaning process itself can push temperatures above the flash point threshold.
- Confined spaces concentrate vapors. Inside a tank or vessel, there’s nowhere for flammable vapors to dissipate. LEL readings can spike rapidly in enclosed environments.
The result: you’re asking your crew to work in a confined space surrounded by flammable vapors, using a chemical that is itself flammable, generating heat through the cleaning process, in an environment where a single ignition source can cause a catastrophic explosion.
What Actually Happens When You Clean a Tank With a Flammable Solvent
Here’s the process most operators use today, whether they think about it this way or not:
- You introduce a flammable liquid into a confined space that already contains hydrocarbon residue and vapors.
- The solvent dissolves the residue, creating a mixture of solvent + hydrocarbon that is even more volatile than either component alone.
- The cleaning process generates additional vapors through agitation, heat, and increased surface area exposure.
- Your crew works in this environment wearing respiratory protection and monitoring LEL readings, hoping the numbers stay below the action level.
- The waste stream is classified as hazardous because it’s a flammable solvent-hydrocarbon mixture that requires specialized treatment and disposal.
Every step in this process adds cost, time, and risk. The solvent itself is expensive. The safety protocols required to work with it are extensive. The waste disposal is a major line item. And the downtime while you wait for the tank to degas after cleaning can stretch into days.
The Numbers: Hasten Cleanse vs. Conventional Solvents
When we run Hasten Cleanse against conventional tank cleaners in side-by-side field trials, here’s what consistently happens:
80% reduction in cleaning downtime. The cleaning cycle is faster because our chemistry bonds to hydrocarbon particles and breaks them down through surfactant action rather than slow dissolution. Tanks that take 3-5 days with solvents are often completed in under 24 hours. Less time cleaning means your tank is back in service sooner — and that’s revenue, not just time.
50% less wastewater generated. Our concentrated formula requires less water to achieve the same clean. That’s not just an environmental win — that’s a disposal cost you’re cutting in half. For operations that pay per barrel of waste hauled, this savings alone can offset the cost of the product.
Zero flammability risk. Water-based. Non-hazardous. Non-corrosive. No flash point. Your crews can work without the constant anxiety of working around a flammable atmosphere. Hot work permits are simplified. JSA reviews are cleaner. Insurance exposure drops.
Simplified waste classification. Because Hasten Cleanse is non-hazardous and biodegradable, the wash water it produces is significantly easier and cheaper to treat than solvent-contaminated waste. This reduces your TCEQ and EPA compliance burden at the same time.
Common Tank Cleaning Fire Incidents
The U.S. Chemical Safety Board (CSB) has investigated dozens of tank cleaning fires and explosions over the past two decades. The pattern is almost always the same: a flammable cleaning chemical or residual product vapors find an ignition source inside or near a tank. The results range from flash burns and equipment damage to fatalities and facility-wide shutdowns.
The ignition sources are varied and often unpredictable:
- Static discharge. Moving liquids through hoses and piping generates static electricity. In a vapor-rich environment inside a tank, a single static spark can ignite the atmosphere. Petroleum-based cleaning solvents increase the concentration of flammable vapors, making static ignition more likely.
- Hot surfaces. Tank walls exposed to direct sunlight in a Texas summer can reach 150°F or higher — well above the flash point of most cleaning solvents. Even after the sun goes down, residual heat in thick steel walls can sustain dangerous temperatures for hours.
- Mechanical friction. Scrapers, pumps, and agitation equipment generate heat through friction. In a confined space filled with flammable vapors, this mechanical energy can provide the ignition source.
- Electrical equipment. Non-explosion-proof lights, fans, or monitoring equipment brought into or near the tank opening can produce sparks. Even a cell phone or two-way radio can theoretically provide enough energy to ignite a flammable atmosphere at the right concentration.
In every one of these scenarios, the severity of the incident depends on one factor: how much flammable vapor is in the space. A water-based cleaning chemistry with no flash point cannot contribute flammable vapor. Period. The background vapors from residual product are the only fuel source, and Hasten Cleanse actively suppresses those.
Insurance and Liability Implications
Every tank cleaning operation with a flammable solvent is a potential catastrophic loss event. Insurance underwriters know this. Your property and casualty insurance premiums reflect the hazardous materials in your facility inventory and the activities being performed with them.
Switching from a flammable cleaning chemical to a non-flammable one is a material change in risk profile that your insurance broker should know about. Some operators have successfully used this change to negotiate lower premiums or more favorable policy terms. At minimum, it removes a potential coverage dispute: if a fire occurs during tank cleaning with a non-flammable chemical, the insurer cannot argue that the cleaning chemical contributed to the loss.
For contractors performing tank cleaning at client facilities, the liability question is even more acute. If your crew brings a flammable solvent onto a client’s property and a fire occurs, the legal and financial exposure is enormous. Carrying a non-flammable cleaning chemistry eliminates this specific liability — and it’s a competitive advantage when bidding work against contractors who still use flammable products.
Making the Decision
The decision to switch from a flammable cleaning chemical to Hasten Cleanse ultimately comes down to a simple risk-reward calculation:
Risk of staying with your current product: Continued fire hazard exposure during every tank cleaning operation. Ongoing liability for your crews, your facility, and your contractors. Higher insurance costs. More complex safety procedures. More expensive waste disposal.
Risk of switching: A few hours of your time to watch a demonstration and evaluate the results.
