The ventilated room is a ventilated area for working with paints, solvents, and other brushed-on/sprayed-on treatments.



The ventilated room has volatile, airborne particles and vapor in it. These and other materials with oil or solvents on them can ignite or spontaneously combust. Fire prevention in the ventilated room is essential.

  • Use only properly maintained sprayers and accessories designed for use in spray booths
  • Don't use electrical devices or anything with flame or that could spark
  • Run the exhaust fan when you are working with oil/solvents in the room
  • Don't wear clothes with oil/solvent on them when working
  • Don't discard materials with solvent or oil on them in the regular trash. Instead throw them in the red metal safety bins. This goes for rags, brushes, stirring sticks, cardboard etc.
  • Don't spray paint or finish on the walls or floor. Protect from overspray with cardboard, paper, dropcloths. Then discard safely.
  • Don't clear the nozzle of your spray can on the wall or floor.
  • For frequent paint/chemical work wear a combination dust/vapor respirator to protect your lungs

Safe Storage

  • Don't store empty containers
  • Don't store or eat food/drink
  • Don't store containers of flammable materials, including paints, thinners, solvents.

Flammables Storage Requirements

  • All flammables must be stored in Building 13 in one of the three metal cabinets. Label each item with name, contact information, and date. After three months items become community property.
  • Only store flammables in your rental space if you have a suitable flammables cabinet and have been given permission by the facilities manager.
  • If you do not have a safety cabinet, DO NOT store flammables in your rental space
  • Any flammables or combustibles stored in The AA cabinet need to have an MSDS brought in with them. Everything needs to be named and dated with when it was brought in. If it is meant to be shared, put a note on it "common use"
  • Yellow is for Class 1 flammables and 2 combustibles
  • The red and blue are for class 3 combustibles.
  • Fuels need to be stored outside in the flammables cage. (propane, Map, Kerosene, etc)

Q: How do I know the class of chemical or storage requirements?

A: The class of chemical will be on the msds with all storage and handling requirements.

Q: The yellow cabinet is out of space for Class 1 and 2 items?

A: This is limited for a reason. FIFO find the oldest thing and bring it hazardous waste disposal in your area.

Q: what about flammables in our spaces?

A: Class 1, 2, and 3, need to be in a metal flammables cabinet. No fuel should be stored in your space that is not in current use.


  • Empty red metal hazardous waste bins as needed, according to protocol [note: the protocol needs to be added in here]
  • Replace the spray booth filters as necessary
  • Clean and maintain all spray booth parts which are subject to wearing out
  • Clean ductwork periodically
  • Don't allow buildup of overspray in the booth, in the ductwork, or on the floor. Build-up is flammable.
  • Remove buildup and discard it in metal safety cans. A little pile of build-up swept together and left can spontaneously combust

Use & Etiquette

  • Paint should only be sprayed in the spray booth with the exhaust fan running. After spraying, move your work to a different location to dry.
  • Clear coat finishes should be applied behind the curtain to reduce the risk of contamination. All users should check that the curtain is shut to reduce airflow.
  • Paint should not be sprayed behind the curtain because of insufficient airflow to vent that corner of the room. Also airborne paint residue damages clear coat finishes.
  • If there is no space in the main room to paint your project, wait to use the main room (i.e. don't spray using paint behind the curtain).
  • All users should provide a name and contact info on or near their project. Before moving a project, try to get the member's permission by reaching out to them using contact info provided.
  • Limit yourself to 24 hours for drying time. Always label projects that are actively drying.

Dust-Free Finish

  • To reduce dust and achieve best results, sweep walls to wall with a dry broom. Discard accumulated overspray in red metal bins. Mop and soak entire floor with mild soap or vinegar. Turn off ventilation and allow dust in room to settle for 15 minutes (high humidity reduces airborne dust). Return to room, close door, turn on ventilation, and proceed with your application.

Rules of Thumb for Consumables and Tools

  • Consumables without an ownership label: Free for all, throw it away if you think it looks hazardous/not useful. Dispose of hazardous items safely.
  • Consumables with an ownership label: Read the label.
  • Tools with ownership labels: go find the owner and ask.
  • Tools without ownership labels and not attended by their owner: Free for all, don't take them out of the Asylum, don't leave them out of the shop unattended, don't take them out of the shop for an extended time.
  • Always put shop tools and consumables back where they belong (if they don't have an obvious home, make one).
  • Other people's projects, e.g. bookshelf that has just been painted: Leave it alone or move it carefully aside.

Reasoning behind the anything-goes approach to tools

Since Asylum tools are not reliably marked, there is no way to distinguish "reasonably obviously Asylum equipment" from unlabeled privately-owned equipment. Non-asylum tools should not be left in a shop. If you accidentally leave something in a shop, then expect people to assume it is an Asylum tool and use it.
