No, fire-breathing dragons would not be biologically possible. The ability to breathe fire would require a biological mechanism to produce and expel a flammable substance, as well as a way to ignite it. There are no known biological systems that could accomplish this, and the energy required to produce and expel fire would be impractical for a living organism. Additionally, the heat and pressure from breathing fire would likely be harmful to the dragon's own body. Therefore, fire-breathing dragons are purely a product of mythology and fiction. **

The professional fire department with low requirements for visual acuity is the New York City Fire Department (FDNY). The FDNY allows candidates with uncorrected vision of 20/100 in each eye to be eligible for the firefighter position. However, candidates must have corrected vision to 20/20 in each eye with the use of glasses or contact lenses. This lower requirement for visual acuity allows individuals with less than perfect vision to still pursue a career as a firefighter in the FDNY. **

For fire protection requirements for dowels, materials such as fire-resistant coatings, intumescent materials, or fire-retardant-treated wood are suitable options. These materials are designed to provide protection against fire by either resisting ignition, slowing down the spread of flames, or expanding to create a barrier against heat and fire. It is important to ensure that the chosen material meets the specific fire protection requirements and standards for the intended application. **
