designing website

We need icons for 10 safety hazards (listed below) that can be used throughout a document to denote each of the hazards, like bookmarks. All icons need to be black and delivered in .png, .pdf, and .ai formats. Details for each icons meaning are given in the attached file on the second page. Both of the images provided have a copyright, but the individual icons do not all have copyrights. For example, "Radiation hazard" and "Biological Hazard" are universal. The safety hazard icons are as follows: - Mechanical hazard - Electrical hazard - Pressure hazard - Temperature hazard - Chemical hazard - Biological hazard - Radiation hazard - Sound hazard - Gravity hazard - Motion hazard We have chosen a fixed price for this project. We would like 1 revision per icon.
