Power Tools
PPE selection, blade and bit safety, kickback prevention, and correct tool for the material.
High risk
72 checklists
Ladders & Heights
Angle, footing, three-point contact, roof access, and when a scaffold beats a ladder.
High risk
41 checklists
Chemicals & Fumes
Ventilation, PPE, mixing rules (and the combinations that create toxic gas), storage, disposal.
Moderate

Every Job Starts With a Stop and Check
Before any repair, the app walks you through a short pre-flight sequence designed by tradespeople. It takes about 90 seconds — and it's the 90 seconds that prevent most avoidable injuries.
- Isolate the hazard — power, water, gas, or load
- Confirm isolation with a tester, not an assumption
- Select PPE for the specific task, not the general category
- Clear your workspace and confirm your exit route
- Identify the stop-signs that mean "call a professional"
Inside the App
Built for the Garage, Not the Boardroom
Big buttons, glove-friendly targets, no sign-up wall, and nothing that needs a signal to work.
Step-by-Step Checklists
Tick items off as you go. The app remembers where you stopped, even if the screen locks.
Works Fully Offline
Every checklist is stored on your device. Basements, lofts, and dead zones are fine.
Stop-Sign Warnings
Clear, non-negotiable callouts when a job crosses into licensed-trade territory.
Hazard Lookup
Search a material, tool, or chemical and get the specific risks and safe handling rules.
PPE Recommender
Tell it the job; it tells you the eye, hand, respiratory, and hearing protection you need.
Emergency Card
One tap to your local utility emergency lines, stored and available offline.
Job History
Keep a private log of what you did and when — useful for warranties and future repairs.
No Ads, No Tracking
We don't sell data, show ads, or require an account. The app is the product.

Written by People Who've Been on the Tools
RepairSafetyGuide started when a licensed electrician got tired of watching homeowners follow video tutorials that skipped the isolation step entirely. The checklists here are written with working tradespeople — electricians, plumbers, gas engineers, and site safety inspectors — and then reviewed again before publishing.
We're deliberately not a "how to do everything" app. We're a safety layer that sits on top of whatever guide you're already following. If a job is genuinely beyond safe DIY, we say so plainly instead of pretending otherwise.

User Feedback
What Users Tell Us
Mostly from people who nearly did something regrettable — and then opened the app first.
"I was about to swap a light switch without killing the breaker because the old YouTube video made it look easy. The app's pre-flight check stopped me cold. Turns out the circuit was still live."
— James T.
"The chemical mixing warnings alone are worth it. I had no idea two common cleaners I'd been storing together could produce something genuinely dangerous."
— Rachel M.
"What I appreciate most is that it tells you when to stop. Half the guides online just assume you should do the job yourself. This one actually says 'get an electrician' when that's the honest answer."
— Priya S.
Questions
Before You Download
Straight answers, including the ones about what we're not.
Is the app actually free?
Yes — the full checklist library is free and there are no ads or paywalled steps. We fund the app through a small optional subscription that adds job logging, PDF exports, and family sharing for people who want them. Nothing safety-critical is ever locked behind a payment.
Does it replace a professional tradesperson?
No, and we're explicit about that. The app helps you do safe DIY work safely, and helps you recognise when a job legally or practically requires a licensed professional. In many jurisdictions, certain electrical, gas, and structural work must be done by a licensed trade — the app flags this clearly.
How does it work without a signal?
Every checklist, hazard entry, and emergency contact is stored on your device when you install the app or download a topic pack. You don't need a connection to use any safety feature. Sync only happens when you're online and choose to.
Do you collect personal data?
No account is required, and we don't sell or share user data. Basic anonymous crash reporting is optional and can be turned off in settings. Job history stays on your device unless you explicitly export it.
Who writes and reviews the checklists?
Content is drafted by our in-house safety team, then reviewed by at least one licensed professional in the relevant trade — electrician, plumber, gas engineer, or site safety inspector. The reviewer's name and credentials appear at the bottom of each checklist.
Is it suitable outside the US and UK?
Yes, though electrical codes, gas regulations, and emergency numbers vary by country. The app detects your region and shows the relevant local emergency contacts and code references where we have them, and defaults to general safety principles where we don't.
What if I think a checklist is wrong?
Tell us. There's a "report this step" button on every checklist that goes straight to our safety team. Corrections are prioritised above new content, and we publish a changelog of safety revisions.
