Some tools you’ve used for years might now be on your local fire department’s “unsafe” list. That can feel confusing, even frustrating. But there’s a reason for these changes, and it’s not just about following rules. Fire departments are seeing new risks as technology and building materials change. What was safe a decade ago might not be safe today. If you use tools at home or work, you need to know why some are now flagged as unsafe. Here’s what’s really going on—and what you can do about it.
1. Lithium-Ion Battery Tools Can Start Fires
Lithium-ion batteries are everywhere. They have power drills, saws, and even flashlights. But these batteries can overheat, catch fire, or even explode if damaged or charged incorrectly. Fire departments have seen a rise in fires caused by these batteries, especially when people use off-brand chargers or store tools in hot places. If you use battery-powered tools, always use the charger that came with the tool. Don’t leave batteries in direct sunlight or in a hot car. If a battery looks swollen or damaged, recycle it safely.
2. Old Extension Cords Can Overheat
Many people use the same extension cords for years. But old cords can fray, crack, or lose their insulation. When that happens, they can overheat and start a fire. Fire departments now flag old or damaged extension cords as unsafe, especially if you use them with high-powered tools. Always check cords before you use them. If you see any damage, replace the cord. Never run extension cords under rugs or through doorways, where they can get pinched or worn down.
3. Propane Torches and Heaters Pose Explosion Risks
Propane torches and portable heaters are common on job sites and in garages. But if you use them in a closed space or near flammable materials, you risk a fire or explosion. Fire departments have responded to many accidents caused by leaking propane or improper storage. If you use propane tools, always check for leaks before lighting. Store propane tanks outside, away from heat sources. Never use these tools in a small, unventilated area.
4. Angle Grinders Can Throw Sparks
Angle grinders are powerful and useful, but they can throw sparks far from the work area. Those sparks can ignite sawdust, paint, or even gasoline fumes. Fire departments now warn against using angle grinders near anything flammable. If you need to use one, clear the area of debris and flammable liquids. Keep a fire extinguisher nearby. Wear protective gear, and never use an angle grinder in a space where fumes might be present.
5. Gasoline-Powered Tools Leak Fumes
Chainsaws, generators, and other gasoline-powered tools can leak fuel or fumes. These fumes are not just a health risk—they can ignite with a single spark. Fire departments have flagged these tools as unsafe if used indoors or stored near ignition sources. Always use gasoline-powered tools outside. Store fuel in approved containers, away from your home or garage. If you smell gasoline, find the source and fix it before using the tool again.
6. Uncertified Tools May Not Meet Safety Standards
Some tools sold online or at discount stores don’t meet safety standards. They might lack proper insulation, have faulty wiring, or use substandard materials. Fire departments now flag uncertified tools as unsafe because they can fail unexpectedly and cause fires or shocks. Always look for certification marks like UL or CSA when buying tools. If a deal seems too good to be true, it probably is. Using certified tools is one of the simplest ways to stay safe.
7. Improper Tool Modifications Increase Risk
It’s tempting to modify a tool to make it work better or fit a specific job. But changing a tool’s wiring, removing safety guards, or using parts not designed for it can make it dangerous. Fire departments have seen fires and injuries caused by modified tools. If you need a tool to do something it wasn’t designed for, look for a tool made for that purpose instead. Never remove safety features or bypass built-in protections.
8. Tools Used Near Flammable Materials
Sometimes, it’s not the tool itself but where you use it. Using a heat gun near paint thinner or a drill near a gas line can be a recipe for disaster. Fire departments now flag certain tools as unsafe if used in risky environments. Always check your surroundings before starting work. Move flammable materials away, and make sure you have good ventilation. If you’re not sure if it’s safe, ask your local fire department for advice.
9. Lack of Regular Maintenance Causes Failures
Tools need regular maintenance to stay safe. Dust, debris, and worn parts can cause overheating or electrical shorts. Fire departments now flag neglected tools as unsafe because they’re more likely to fail. Clean your tools after each use. Replace worn parts right away. If a tool starts making strange noises or smells hot, stop using it and get it checked.
10. Outdated Tools Don’t Meet Modern Safety Codes
Some older tools just aren’t built to today’s safety standards. They might lack automatic shut-offs, proper insulation, or other features that prevent fires. Fire departments now flag outdated tools as unsafe, especially in workplaces. If you’re still using tools from decades ago, it might be time to upgrade. Modern tools are safer and often more efficient.
Staying Safe Means Staying Informed
Fire departments aren’t trying to make your life harder. They’re responding to real risks that come with new technology, old equipment, and changing work habits. If a tool is flagged as unsafe, it’s for a reason. Take the warning seriously. Check your tools, follow safety guidelines, and stay up to date on what’s considered safe. Your safety—and your family’s—depends on it.
