Fire-safing vs fire-stopping

    Fire-safing is essentially a type of firestopping.  Any installation where you are infilling some sort of joint or penetration with a fire-resistant assembly classifies as firestopping.  Fire-safing is one method of firestopping, and traditionally involves a "fire safing material" which is often mineral wool.  You see fire safing/mineral wool type assemblies at the edges of curtain walls and expansion joints.  

    Hope that helps.
