MDF-500 can be applied as a fog (atomized mist), foam or spray. The fog application is the preferred application
method as it allows for not only horizontal surface decontamination but ALL surfaces present. In other words, the
fog application completely decontaminates every surface in a room. The exact application procedures will vary
depending on the circumstances. Our subject matter experts can consult with your team of experts to assess your
needs and provide site-specific application procedures (to include written application procedures) with hands-on
training after you take delivery of your MDF-500. EPA approved application equipment will be proposed as part of
our overall solution.
