Install a restroom exhaust fan, Linden STEM Academy

A K-6 restroom at Linden STEM Academy has no working exhaust, letting humidity and odor build up all day in a heavily-used space. Standard: ASHRAE 62.1 ventilation + EPA IAQ baseline (CO2, PM2.5, VOC, RH); LBC Health+Happiness petal. Proof: Before photo of the restroom ceiling + Install photos of the fan housing and duct run + Airflow test photo/video at the exterior vent cap Method (ASHRAE 62.1 ventilation + EPA IAQ baseline (CO2, PM2.5, VOC, RH); LBC Health+Happiness petal.): 1. Photograph the restroom ceiling/existing fan and confirm the duct route to the exterior. 2. Mount the new fan housing to the ceiling structure per the fan's rough-in spec. 3. Connect the duct to the exterior vent cap and the switch wiring per a licensed electrician's hookup. 4. Test for proper exterior airflow (tissue test at the vent cap) and photograph the finished install. Done when: Before photo of the restroom ceiling + Install photos of the fan housing and duct run + Airflow test photo/video at the exterior vent cap

$100 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.

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.
