Using an effective hand sanitizer is one of the most important things everyone can do to help prevent the spread of COVID-19. This is especially true on construction jobsites and in mechanical service areas where there is no running water. To be effective against COVID-19, the CDC states that hand sanitizers must contain at least 70% alcohol. Since alcohol is flammable, we must be extremely careful when using it. Many things on a jobsite can serve as an ignition source, such as a lighter, a welding torch striker, welding and grinding sparks, even static electricity.
