Generally, No. I, personally, have never seen one and am relatively certain that no dust mask protects users against asbestos. When you purchase a dust mask, on the box will tell you what types of particles the mask will protect you from. Most boxes will specifically state that the masks Do NOT protect against asbestos. Those that handle asbestos use specially designed respirators.
Conditions that involve small airborne particles (such as construction sites) are conditions that would require one to wear a dust mask. Similarly, if one is working with a hazardous chemical or substance (such as asbestos), a dust mask would be required to protect one's self from harm.

The construction workers- professionalist and amateurs- wear dust masks (also called "disposable dust respirators") to protect themselves from many dangerous or harmful substances that are present on construction sites or in houses during construction, remodeling and demolition works in form of dust, mist or fume. Most dangerous are asbestos fibers, which are present in some type of roofing and in insulating and fireproof materials. There are although many dangerous substances in such environment: silica dust(silicosis risk!) from concrete and masonry, wood dust, paint chips and dust, fiberglass insulation( not asbestos, but also harmful or irritant to mucous membrames), sometimes mold and other chemicals. So, if the workers aren't stupid, they always wear dust mask! Working with mask on provides you longer life without serious and unpleasant lung diseases!
