Safety Regulations

(draft)

<toggledisplay> §1 Following the Rules

§1.1 We understand that we need to precisely follow the rules listed below. Failing to do so will result in being disallowed to use the laser cutter as well as the prototyping laboratory in general.

§1.2 We understand that in failing to follow the rules we might damage the laser cutter and that we will be held liable for any caused damage.

§1.3 We understand that in failing to follow the rules we pose a hazard to ourselves as well as fellow people and that we will be held liable for any caused damage and health issues.


§2 Operation

§2.1 Before every single use of the laser cutter we make sure that the machine as well as the peripheral machines are working properly. The Laboratory provides a list of things to check before using the laser cutter. This list needs to be followed precisely. Among other things the list will include checking the mirrors, checking the lense and checking the filter system.

§2.2 We never deactivate the laser cutters built-in security mechanisms.

§2.3 We never leave the machine alone while it is operating. There is a chance of materials catching fire.


§3 Materials

§3.1 We never cut unknown materials. There are reliable procedures to identify materials. Cutting unknown materials might damage your health.

§3.2 We never cut PVC or Teflon.

§3.3 We always research material properties. In case of doubt we use a different material.

§3.4 We do not cut food. We understand that the laser cutter s extreme temperatures can cause unwanted transformations in the chemical structure that might render the food inedible or poisonous.

§3.5 We never cut explosives, combustible or inflamable materials. </toggledisplay>

Material List

We are maintaining a list of materials [1] in which we document our experiences. This list also includes materials that are not usable with a laser cutter.

It is absolutely mandatory for you to contribute to this list. If you have found a good preset save it on the laser cutter computer and submit your material research by using this form.
