Technician B is correct because a disposable dust mask is typically made from paper with a wire-reinforced edge and is held to the face with an elastic strip. Technician A is incorrect because a disposable dust mask is not suitable for protection against chemicals like paint solvents; a respirator designed for chemical vapors should be used instead.
