Precautions:

1. Each individual draw cord will have it's own tassel to prevent a loop condition which is a strangulation hazard.
2. Draw cords will have a washer assembly mounted just below cord lock when the blind is in the lowered position to prevent the lift cords from being pulled from ladder; again, creating a strangulation hazard.
3. The taller a blind is, generally the longer it's lift cord is.  When it's in a raised position, lift cord is not only in close proximity of floor; sometimes it's on the floor.  This also can present a hazard.  On several occasions, customers have cut the lift cords shorter.  This is alright, assuming you do so when the blind is in a lowered position; doing so while in a raised state will render the blind inoperable.
