Purpose

The purpose of the Small Hall Makerspace is to allow students to design, build, and test small electronic circuits; experiment with rapid prototyping technologies. This document aims to ensure that all activities are conducted safely.

Background

A makerspace is a location where people with common interests can meet, socialize and/or collaborate. Makerspaces can be viewed as open community labs incorporating elements of machine shops, workshops and/or studios where makers can come together to share resources and knowledge to build and make things. The makerspace provides the tools, the makers bring their creativity.

Authority and Responsibility

Wouter Deconinck (757-221-3539) and Joshua Erlich (757-221-3763) are jointly responsible for the operation of Small Hall Makerspace equipment in conformance with these procedures.

Hazard Analysis

Hazard Identification

1. Skin Hazard from heating elements
2. Bodily Damage Hazard from high speed rotary tools
3. Eye Hazard from shavings launched from high speed rotary tools
4. Ear Hazard from prolonged exposure to noise of high speed rotary tools
5. Fire Hazard from friction caused by high speed rotary tools
6. Bodily Damage Hazard from sharp hand and power tools
7. Skin Hazard from dust
8. Lung Hazard from dust
9. Fire Hazard from flammable objects
10. Skin Hazard from chemicals
11. Electrical Hazard from power outlets and cables

Hazard Mitigation

1. Mitigation of Skin Hazard from heating elements
   • There are heating elements in the nozzle of the 3D printer, the nozzle of the filament extruders, as well as in the tips of the soldering irons.
   • Do not touch any of the heating elements while they are activated.
   • Always place heated soldering irons in their holders.
   • Never rest heated soldering irons on a working surface.
2. Mitigation of Bodily Damage Hazard from high speed rotary tools
   • Do not touch the high speed rotors while they are spinning
3. Mitigation of Eye hazard from shavings launched from high speed rotary tools
   • The generic tool operates at speeds up to 30,000 rpm with a power of 120 W, while the DeWalt tool operates at speeds up to 30,000 rpm with a power of 600 W. At these speeds there is potential for shavings to be projected towards the operator and nearby users.
   • While operating CNC routers the operator and users within a 3 meter radius are required to wear eye protection (safety glasses)
   • Be aware of the danger of flying shavings, and try to stay away from the tool in use as much as possible.
4. Mitigation of Ear Hazard from prolonged exposure to noise of high speed rotary tools
   • If CNC routers are use for longer than 2 minutes, all users in the makerspace are required to wear hearing protection (foam ear plugs.)
5. Mitigation of Fire Hazard from friction caused by high speed rotary tools
   • A CO2 fire extinguisher must be present when CNC routers are being operated
   • When increasing the rotary velocity on a new material (including the first turn-on) the temperature of the spindle must be checked with a thermometer after approximately 30 seconds of operation.
6. Mitigation of Bodily Damage Hazard from sharp hand and power tools
   • Before any hand or power tool is operated, the users must familiarize themselves with the proper operating procedures as outlined in the owner’s manual.
   • There must be at least two people in the makerspace whenever power tools are in use.
7. Mitigation of Skin Hazard from dust
   • Dust created by the operation of various grinding and milling tools (including CNC routers and drills) is potentially hazardous, depending on the material being used. For example, walnut wood sawdust is an irritant to the skin and the airways.
8. Mitigation of Lung Hazard from dust
   • If CNC routers are used to cut materials that cause visible airborne dust build-up, a dust collection system must be used (shop vac with dedicated collection sleeve) and all users in the makerspace must wear dust masks.
   • When uncontained visible airborne dust build-up occurs when operating power tools or CNC routers, all work must cease to prevent false fire alarms.
   • When any skin or airways irritation is noticed, all work must cease.
9. Mitigation of Fire Hazard from flammable objects
   • Any type of open flame is not allowed in the makerspace
   • Keep all objects at least 18” from the ceiling
   • Do not block power outlets with with anything
   • Keep an 18” clearance around all fire alarms
10. Mitigation of Skin Hazard from Chemicals
    • Follow all safe handling procedures for each chemical in use.
    • Keep an 18” clearance to the left and the right of the chemical cabinet
    • Do not put anything on top of the chemical cabinet
    • The inventory of the Chemical Cabinet should correspond to the list on the makerspace website. All new chemicals should be reported to Sandra Prior for approval and listing.
11. Mitigation of Electrical Hazard from outlets and cables
    • Do not bring any food into the makerspace, all drinks must be in closed containers.

Waste Disposal

Any garbage created should be immediately disposed of in the proper waste bins. Some materials must be disposed of carefully, so make sure to familiarize yourself with the SOP of anything you use that produces hazardous waste.

Hazardous Materials

No radioactive or hazardous materials are allowed in the Small Hall Makerspace.

Hazardous materials are understood to be chemicals that are carcinogens, toxic or highly toxic agents, reproductive toxins, irritants, corrosives, hepatotoxins, nephrotoxins, neurotoxins, agents that act on the hematopoietic system, and agents that damage the lungs, skin, eyes, or mucous membranes; chemicals that are combustible liquids, compressed gases, explosives, flammable liquids, flammable solids, organic peroxides, oxidizers, pyrophorics, unstable (reactive) or water-reactive; and chemicals that, in the course of normal handling, use or storage, may produce or release dusts, gases, fumes, vapors, mists or smoke having any of the above characteristics.

Procedures

All tools have a standard operating procedure. Make sure to familiarize yourself with each one before using the tool in question.

Makerspace Clean-up Checklist

Before you leave the makerspace:

• clean up all detritus left over from projects
• Ensure that all tools are put away in their proper places.
• Turn off the light switches.

Training

There is no inherent training required for the use of the makerspace, besides the reading and signing of this SOP. There is training, however, that is required for the use of the 3D printer and router. Refer to their SOP to find out how to schedule a training session.

Emergency Response

In case of emergencies, dial 911, and evacuate the makerspace.
