Every member must read and sign the shop safety waiver before participating in shop activities.

General Safety[edit]

By far the best safety practice is to be aware of your surroundings. Be aware of and protect yourself from welding flash, sparks, hot metals, sharp edges, noise, and any other hazards in the shop. Do not hesitate to ask! Wear safety glasses!

With any cutting or machining process, there should only be 2 degrees of motion max. For instance, in a drilling process, rotation of the drill bit and the plunge of the drill into the work material are the two degrees of motion. Either the work material or the drill must be fixed for a safe process. If you are unsure about a method, ask!

See Fire policies for more information.

Welding Safety[edit]

Welding processes give of intense light and radiation that will permanently damage eyes and skin. Wear long sleeves and pants to protect the skin and do not look at the welding flash. This is about like walking out of a dark room and looking directly at the sun, but worse.

Severe "sun" burns and needle like pain in the back of the eye can result from overexposure to the welding flash.

Welders must take Hot Works training.

The use of welding gloves, helmets, and ventilation is required in addition to the above protections. Notify others nearby before welding by shouting "Welding!" Metal will be at and around the location welded. Handle hot metal with pliers or vice-grips, not gloves. Gloves will be ruined by repeated contact with hot surfaces.

Do NOT use brake fluid to clean parts for welding, or weld near brake fluid at all. This produces phosgene gas, which was used in World War I as a chemical weapon.

Milling and Lathing[edit]

You must take Shop Safety Training.

Rotational inertia is the most dangerous aspect of mills and lathes. The potential to be caught up in or struck by the work piece or other rotating parts is immense. Deaths have occurred. Long hair must be tied back, loose jewelry and clothing avoided. Be aware where your hands are in relation to the cutting tool at all times! If you want to adjust the work piece or cutting tool, turn off the machine first.

Clamp the work piece well, and never leave a chuck key or wrench on the machine in case of accidental power up while it is still there. Wear safety glasses. As a general rule, if it is making a bad/unhappy noise, the bit is too dull, the speed is incorrect, or there is not enough lubricant.

Be aware of hot chips that may come off the work piece.

Always ask if you are unsure!

Electrical and Soldering[edit]

Don't poke your eye out with the wire.

Hot Works training must be completed before soldering. Use proper ventilation when soldering, as the flux will give you cancer if you in hail it.

Chemical Processes[edit]

Respirator Training must be completed before using one for painting, sanding, or other work.

Epoxy, solvents, and other chemicals have the potential to give off harmful fumes. Store in the correct location and use proper ventilation and gloves, if applicable.

See Chemical storage for more information on storage of chemicals.
