You Find a Serious Safety Hazard Unrelated to the Call: Decision Tree

Why this matters

Finding a hazard you were not called for puts you on the clock in a way the original job never did. The wrong instinct, finish my task and mention it on the way out, can leave a live danger running for the time it takes you to pack up. This tree sorts the find by how fast it can hurt someone and tells you the first action for each. Severity first, everything else after.

Start here: is anyone in immediate danger?

Before you classify anything, answer one question: can this hurt someone in the next minutes to hours if nothing is done? If yes, act now.

• Gas smell, carbon monoxide source, or active arcing or fire: stop, make safe, and for gas or fire lead with the evacuation and utility-call sequence. Do not finish your original task first.
• Live exposed conductors, water on electricity, a pool bonding fault, an unvented combustion appliance: de-energize or shut off the source and verify it is dead or stopped before you touch anything.

Only once immediate danger is neutralized do you classify and continue.

Branch 1: Immediate hazard, make safe then disclose

If it can hurt someone now:

1. Take the make-safe action (shut off, de-energize and verify, stop the equipment, evacuate for gas or fire).
2. Lock out or red-tag so it is not restored by accident.
3. Disclose immediately and in person, not on the invoice later.
4. If it is outside your trade or beyond a temporary make-safe, call the utility, the authority having jurisdiction, or a licensed specialist as the situation demands.

You do not leave an immediate hazard energized on the customer's preference.

Branch 2: Serious but latent, disclose and document

If it is dangerous but not going to hurt someone in the next hours (a double-tapped breaker, a missing GFCI near water, a dryer vent packed with lint, a capped relief-valve discharge, a corroded gas connector not currently leaking):

• Photograph it and write it up with what it can cause.
• Disclose plainly and give the customer the fix or a referral.
• Recommend a timeline honestly: soon, but not an evacuate-now.

Latent does not mean minor. It means you have time to do it right, not time to ignore it.

Branch 3: Informational, note it and move on

If it is a code deviation or a wear item that is not a safety threat (a non-hazardous non-compliance, cosmetic corrosion, an aging but functioning part), note it on your report so the customer knows, and let them prioritize. Do not inflate it into an emergency to sell work.

Match the response to the severity, not the sale

The discipline this tree protects: your response is set by how fast the hazard can hurt someone, never by whether you happen to be able to fix it or want to. A latent hazard you can fix today is still latent; an immediate hazard outside your trade is still immediate. Classify honestly.

Recap

1. Immediate-danger question first; if yes, make safe before anything else.
2. Immediate: make safe, lock out, disclose in person, call for help if needed.
3. Latent: document, disclose, fix or refer on an honest timeline.
4. Informational: note it, do not inflate it.
