An adult stands safely on a clear hallway floor looking at a door edge with a notebook, while the ceiling access hatch remains firmly closed.
Lesson 1, Topic 4 of 4

Set permissions and limits

Use an observation-only boundary for the first walkthrough. Stay on ordinary accessible floors, leave covers and panels in place, and do not disturb insulation, wiring, fuel equipment or suspect materials.

Do not manufacture a pressure difference using fans or use smoke or flame to search for leaks in this course. A renter can document a concern and seek permission; ownership also does not establish technical competence.

These are conservative course boundaries, not a substitute for local rules or a professional safety assessment. If a possible urgent hazard arises, the routine audit stops. Otherwise, an inaccessible area becomes a question for the appropriate person rather than an invitation to climb or dismantle.

Try the supplied case

Hypothetical choices: photograph a visible worn door seal from the floor; remove an electrical cover to feel for drafts; enter a dark attic using an unfamiliar ladder. Morgan has observation-only permission.

Choose the permitted first task and record the two deferred tasks in the goal section.

Compare your response

Photograph the visible door seal from the floor. Defer electrical-cover removal and attic entry; ask the landlord or qualified provider about appropriate inspection.

The first task fits the stated permission and needs no disassembly or access equipment. A useful boundary is specific enough to guide action, rather than a vague instruction to be careful.

You now have an audit question and an observation-only boundary. Next, use the bill’s quantities and dates to test whether a larger total really means greater daily energy use.
