Safety Regulations

Use of this facility requires the use of standard safety precautions at all times. To include but not limited to:

Never work alone you must use the buddy system. Both buddies must have the appropriate shop training and qualifications for the type of work being performed and tools being used. They must be within immediate sight and sound of each other and familiar with emergency shut-off of the equipment.
Be aware of how to stop the machine you’re planning to use, and how to call for help (dial 100 from any MIT phone for medical, police, and fire emergencies).
Safety glasses are your responsibility. You may not work in this space without them. If there aren’t any available when you enter the shop, its no excuse to work without them.
Only closed-toe shoes may be worn
Long hair should be tied up, loose clothes should be tightened, and dangling jewelry should be removed. These can all get caught in the machines.
Do not leave tools in the machine when you’re done. Put them in their proper home.
Always know the safe operation of the machines you wish to run. If unfamiliar with a particular machine, see the shop staff.
Do not make parts in haste. Plan your job and procedures in advance. Determine what special tools you may need.
Use the shopvac to remove chips from a machine; do NOT use your hands
Wear a dust mask when performing grinding or other operations that may generate fine airborne particles
You are required to report all issued, accidents, and tool breakages to John DiFrancesco or Tom Lutz.
You will not grant permission for any use of this facility. Access to this machine shop is through the shop administrative group only.
No food is allowed in the shop.
Gloves must not be worn around most machine tools.
Respect the machines and what they can (and can’t) do never, ever use the machines for anything other than what they were designed to do, and never tamper, alter, or play with the equipment!
You are required to clean your machine and sweep your work area before leaving.

Tools and Materials

(a) Tools in the shop are the responsibility of the user. If they were missing when you came in, tell us. If it is broken we will do our best to replace it. Do not remove any tools from the shop. We may be able to loan some special tools. An ID is required for any tool loan. This will be handled on a case by case basis. Plan ahead for tool needs.

(b) Materials are not provided. Shop staff may be able to direct you to resources and vendors for your machine materials. There are designated scrap areas but they are not to be relied upon.

(c) Do not store any materials in the shop. Do not add or store any furniture or equipment in the shop without permission. Do not leave unfinished projects in the shop without permission. You must remove projects to leave the space available for other users. If such parts are found they may become part of a scrap pile!

Violation of any of the above or improper use of the machine shop may result in loss of access to this facility. The machine shop is an evolutionary process. More machines and tools will be added over time. A degree of responsibility in maintaining the shop is assumed on the part of the students using the facility. This includes cleaning up after oneself, returning tools to their appropriate locations, not leaving parts in the machines overnight, etc.
