General Shop Conduct and Safety Rules
Never work in the shop while tired, intoxicated, or otherwise impaired.
Always use common sense. Before undertaking an operation with a tool, think out the path of the tool and your body. Never place yourself in the path of a tool or apply pressure that will strike a sharp edge with your body should something slip.
Eye protection must be worn at all times when in the workshop. This applies regardless if you are working on machinery or not. Activities of others can affect your safety.
Hearing protection is available. Use it when operating loud machinery.
If you are unsure of proper operation of a tool or machine or uncomfortable with its use, ask for a shop supervisor for assistance.
No member is allowed to work in the any shop alone. Period. You must have at least one other person with you. If there is an accident, the other person can call for help and come to your aid.
Obtain first aid immediately for any injury. Report all accidents/injuries to the shop supervisor no matter how insignificant they may seem at the time. Complete an Incident Report Form and give it to the shop supervisor. This will help us to mitigate hazards in the future.
Do not operate machinery that you have not been authorized to use. This will protect both you and the equipment from harm. All Red class tools and materials require machine specific training and are not to be used unless the shop supervisor grants authorization. See the shop supervisor, not your partner for proper instruction.
Only TVCOG members are permitted to operate in the workshop. Keeping the foot traffic to a minimum provides for a safer and more comfortable working environment. Advance authorization from the machine shop supervisor is required for others to enter the shop.
No pets allowed in the workshop.
Do not attempt to oil, clean, adjust or repair any machine while it is running. Performing maintenance on moving machinery exposes you to additional hazards. We wish to reduce hazardous situations. If you feel a tool or machine is in need of maintenance, please inform the shop supervisor.
Ensure that all machine guarding is in place and functioning properly. Inform the machine shop supervisor if the guarding is damaged or malfunctioning.
Do not leave machines running unattended. Others may not notice the machine is running and be injured by moving tooling.
Do not try to stop the machine with your hands or body. Stopping the machine with your body can result in entanglement. Let the machine come to a stop naturally or use provided brakes.
Always keep hands, hair, feet etc. clear of all moving machinery at all times. Be aware of all moving parts, especially blades, cutting tools and chucks.
Double-check that tooling and work pieces are properly supported and clamped prior to starting the machine. Starting a spindle with loose tooling or machining a loosely clamped work piece can produce flying hazards.
Heavy or unwieldy work pieces often require special support structures to machine safely. Ask for help if you are unsure if your work piece requires additional support.
Remove chuck keys, wrenches and other tools from machines after making adjustments. Chuck keys left in the chuck when the machine turns on become dangerous flying objects. Return chuck keys to their proper storage location.
Ask for help when moving awkward or heavy objects. This will protect you and those around you from injury.
Deburr sharp edges of freshly cut stock. This includes the piece of stock that goes back in the stock rack. Eliminating burred edges minimizes the chances for personal injury and marring of precision machine surfaces.
When working with another person, only one person should operate the machine.
Do not lean against the machines. If you need a rest, grab a chair.
Do not talk unnecessarily while operating a machine. Do not talk to others while they are operating a machine. Do not become a distraction to others. Concentrate on the work and the machine at all times. If you must talk, turn off the machine.
Be sure you have sufficient light to see clearly when performing any job. Well lit workspaces are much safer and less straining on the operator.
Work at a pace that is comfortable for you. Rushing will compromise safe working practices along with part quality and increases the chance of damaging equipment. Set your work aside if you become tired.
Listen to the machine(s) - if something does not sound right, shut it down. Often if the machine sounds abnormal to you, it probably is not operating properly. Inform the shop supervisor if you believe a machine or tool be operating abnormally.
Never use compressed air for cleaning machinery. This will embed particulates into the precision machine ways and will drastically reduce the life of the machine tool. Use the supplied chip brushes and rags to clean machinery.
Never use compressed air to clean your clothes or any part of your body. Particles can become embedded in skin and eyes. In extreme cases, air can be introduced into the bloodstream.
Loss of keys or card access associated with the shop is to be reported to the shop supervisor immediately.
If you do not know how to do something – ASK! Do not engage in any activity that may have unusual risk. Trust your judgment. Check with the shop supervisor if you have any doubts about what you are doing.
Shop Cleanliness Rules
Keep floors free of oil, grease or any other liquid. Clean up spilled liquids immediately, they are slipping hazards.
Store materials in such a way that they cannot become tripping hazards. Immediately return all excess material to its proper storage place.
Put tools away when not in use. This prevents loss of tools and also makes them available to others.
Place all scrap in the appropriate marked scrap containers. Metals are sorted by type.
Use provided trash containers. Do not place hazardous materials in trash containers. Stop work 10 minutes prior to the time you need to leave the shop or that the shop is scheduled to close. This will provide ample time to clean and replace tools to their homes.
KEEP THE SHOP CLEAN AT ALL TIMES. It is all of our responsibility to keep the shop clean. There is no excuse for a cluttered/messy workspace. If your workspace is cluttered, then you are working too fast.
No open toed shoes or high heels. To provide secure footing, choose shoes with softer soles and stable platforms. Wearing appropriate footwear will help protect feet from falling objects and hot sparks or chips. Steel toed shoes are recommended.
No loose clothing allowed. This includes but is not limited to ties, scarves and loose- sleeved shirts. Short sleeves or sleeves rolled above the elbow are preferred. When welding, long sleeves are required for protection from arc-flash and metal sparks and a leather apron is recommended.
No shorts, dresses or skirts allowed when working in the metal shop. Burred edges of freshly metal such as sheet stock are razor sharp. Wearing of long pants will protect you and those around you. Additionally, hot chips will burn/cut exposed skin potentially startling the operator.
Remove all jewelry that could be caught in moving machinery. This includes rings and loose bracelets. Remove necklaces and the like, if not securely restrained.
Restrain all hair that has potential for entanglement with moving machinery.
Wearing of gloves when working on moving machinery is prohibited. Gloves can easily become entangled in moving machinery and thus are not allowed.. The only exceptions to this rule are; 1) the wearing membranous gloves (such as latex or nitrile) for personal protection or contamination control; 2) The wearing of gloves while using a bench or portable grinder or buffing wheel. If you need to wear gloves, see workshop supervisor for acceptable types for your application.
For Emergency Assistance Immediately dial 911 and inform the Safety Officer as soon as possible.
