Check the indoor air at Public library, Bridgeport CT

Public library, Bridgeport CT is used by kids and staff every day, and the indoor air has never been measured. Take CO2 and PM2.5 readings during a normal occupied period so the building knows if ventilation needs attention.

$280 proposed

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

photo of meter in room + GPS + CO2/PM2.5/RH log over occupied period

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

• Photo of monitor in the occupied room
• GPS / address confirm
• CO2 log (ppm) over an occupied period
• PM2.5 reading (µg/m³)
• Relative humidity + temp
• Ventilation observation note

Proof is measured against these, not judged by taste.

The standard this serves

Indoor Air Quality. Indoor air quality is the health of the air where people actually live, and most of us are indoors nine hours in ten. The standards give it numbers: carbon dioxide that tells whether fresh air is reaching a room, fine dust, fumes from finishes, moisture that invites mold. Mastery looks like reading a room's air the way a doctor reads a pulse, and knowing which fix matters first. It is learned meter in hand. This packet is one room measured honestly, and one measured room is worth a hundred guesses.
