Indiegogo has an active fundraiser for an app that will allow crew members to anonymously report safety violations on set. The app will be free once developed. The "Pledge to Sarah" Safety App is in the late camera assistant Sarah Jones's honor. You can support this fundraiser with as little as $1. As of the writing of this blog post, the project reached $2,942 of its $3,400 goal.
Please note there are no special perks for this fundraiser. However, our lives as crew members should not be monetized. If you believe sets should be as safe as possible, please consider supporting this campaign.
