MakerWorks Safety Policy

Last reviewed: Alisha Schor, 09/24/15

Revision #: 2.3

Purpose: This document provides the safety policy for MakerWorks.

You use machines to make parts in a shop. The MakerWorks community must ensure that none of these four components are at undue risk or damaged.

Use of MakerWorks is not a right, it is a privilege.

Failure to follow the safety policy will result in corrective measures ranging from verbal warning to being removed/banned from MakerWorks. Initial corrective measures are at the discretion of the on-duty mentor. Appeals may be made to the Maker Czar via email. Repeated violations or egregiously unsafe actions result in a permanent ban.

Users must acknowledge they have read and understand the MakerWorks User Agreement prior to using any equipment in MakerWorks.

Personal Safety

Never work alone.  A Mentor must be present at all times.  

You must always check in with a Mentor upon arrival in the shop and seek permission to use the facility.

If the shop is at maximum capacity, Users will be turned away until a later time.

Wear the appropriate attire (REQUIRED!):


Closed-toed shoes: covered instep, thick sole, no heels above 1 inch (25.4 mm)

Long hair (including long beards) tied back so that it can not be entangled in a machine

No loose clothing (e.g. ties, scarves, sweatshirt strings, loose sleeves, or headphones) that can become entangled in a machine.

No jewelry (e.g. rings, bracelets, hanging necklaces, watches, or dangling earrings)

No gloves, other than latex or nitrile gloves, may be used while machining.

Appropriate Personal Protective Equipment (PPE) for specific operations or equipment (e.g. hearing protection).  Users must also ensure that others around them are suitably outfitted before starting work that could put others at risk (e.g. are people in close proximity wearing safety glasses?).

Do not rush. Stop, think, and check before you start machining.

Do not work when you are tired. 

Never use hands, fingers or compressed air to remove chips and shavings; use brushes, hooks, vacuums, or other tools.

Machines must be in a state where there are no exposed moving parts that pose a safety risk prior to user attempts to perform chip removal.

Voltage > 50 V for personal projects requires mentor check for proper high voltage safety design.


If you’ve broken something, don’t worry, just tell us about it and it’s okay.

Do not use damaged tools or equipment, equipment that is tagged out of service, or equipment that does not appear to be operating normally. Inform a Mentor immediately.

Only use the machines that you have been trained and certified to use.

Do not leave machines running unattended.

Do not modify equipment (including machine guards).

Do not try to stop moving components with your hand or other tools. Always ensure that a machine has completely stopped and will not move unexpectedly before placing your hands in the work area.

There must always be a single user as the designated operator. If control/use of the machine switches to another user, this must be confirmed verbally and may only happen when the machine is off, and all moving parts are stopped.

Properly secure the workpiece. Avoid fixturing the workpiece with your hands by using clamps and other fixturing equipment.

Check with a mentor if you are not sure how to secure a workpiece.

Never leave a chuck key in a chuck.

Read all labels around the shop and on machines.


Clean up. Leave the machine, floor, and surrounding areas better than you found it.

No running.

Avoid distractions and avoid being a distraction.

Aisles, exits, and access to emergency equipment must be kept clear at all times.

Cell phones, music players, and other personal electronic devices must not be used when running any machine.  Loud music is prohibited.

Food and drink are not permitted.

Ask mentors for help. If you have any questions, ask a mentor, not LMP staff.

Immediately inform a Mentor of any problems, concerns and injuries.

Mentors have full authority over the shop and its safe use, including the responsibility and authority to prohibit shop or tool access for the safety of an individual, others in the shop, or the equipment.

All users have the ability to speak up and ask other users to change behavior (or report their behavior to a Mentor) if they observe unsafe actions.
