In order to ensure the safety of both users and surrounding materials, it is important to know some key things about using resin in a vacuum. First and foremost, be sure to include a resin trap in the vacuum line between the mold and the vacuum pump if there is any possibility that resin can enter the vacuum line while still infusing. Additionally, be aware of how much resin you are working with and make sure to wear protective clothing and eye gear if necessary. Finally, keep in mind that vacuum settings can cause extreme heat, so exercise caution when working with high-heat materials.
