Keep a week-long indoor air diary at an invited Zarqa home (2026-07-18)

Zarqa is one of Jordan's most industrialized cities, and households near its factory corridor often notice dust and haze on bad days but have no simple daily record connecting how the home feels to what's actually in the air outside. Standard: WHO Guidelines for Indoor Air Quality — SDG 3 (Good Health and Well-Being). Proof: Daily photo log plus written diary. Method (WHO Guidelines for Indoor Air Quality — SDG 3 (Good Health and Well-Being).): 1. Confirm the host wants a week of daily air notes. 2. Each day, note whether windows were open or closed and any dust/haze noticed. 3. Photograph a window ledge or sill each day to show visible dust build-up. 4. Log the date and a one-line note each day. 5. Submit the completed week's diary. Done when: Daily photo log plus written diary.

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash. You see which before you claim, never after.

Proof

Daily photo log plus written diary.

This is exactly what gets it approved. Nothing settles without it.

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 45–90 minutes. Method of record: ASHRAE 62.1 + EPA IAQ / moisture baseline

Bring

• CO2 monitor
• PM2.5 monitor
• temp/RH meter
• moisture meter (mold/moisture scope)
• GPS/address
• camera

Steps

1. 1. Confirm the room/unit and address; coordinate to sample during normal occupancy where relevant.
2. 2. Photograph the space and any staining/damp/mold.
3. 3. Place the monitor in the occupied zone; log CO2 over >=1 occupied hour.
4. 4. Record PM2.5, temperature, and relative humidity.
5. 5. For moisture/mold scope, take moisture-meter readings at affected vs baseline areas and estimate visible mold area.
6. 6. Note ventilation type and any obvious deficiencies.
7. 7. Enter the logs, readings, extent notes, photos into the proof record; sign.

If it does not match the plan

• Carbon monoxide > 9 ppm sustained in an occupied space, or any audible CO alarm -> STOP: life-safety hazard. Evacuate, ventilate, and call the gas utility / fire department now. The agent escalates immediately, never sources the leak (NIOSH/ASHRAE CO).
• CO2 sustained > 2000 ppm in an occupied space -> flag acute under-ventilation: recommend increasing outdoor air and reducing occupancy immediately and report to the facility manager (well above the 1000 ppm ASHRAE 62.1 comfort flag).
• CO2 sustained > 1000 ppm -> flag under-ventilation vs ASHRAE 62.1.
• PM2.5 > 35 ug/m3 (24-hr, EPA NAAQS) -> flag elevated particulate; > 55 ug/m3 -> recommend occupants limit exposure / use filtration now.
• Visible mold > 10 sq ft OR active water intrusion -> document only, do not disturb; route to a licensed remediation pro (EPA mold guidance); occupants with respiratory symptoms routed to relocate.

What counts as done

• CO2 logged over >=1 occupied hour
• PM2.5, temperature, and RH recorded
• Moisture readings + visible-mold extent recorded (moisture scope)
• Timestamped photos + address confirm

Proof is measured against these, not judged by taste.
