Unclear instructions are more dangerous and fatal than no instructions at all. In the following instance, there is a fire alarm that denotes “Pull Down” for its operation. Below the fire alarm, there is a notice about not placing anything below the alarm. The notice is self-contradictory of the instruction it tends to preach.
The notice could have been placed elsewhere, maybe on the left or ride side of the fire alarm in order to avoid any inconvenience or confusion. The fire alarm will be questionable to operate as right below the “pull-down” trigger, there is this big notice stating that do not put anything below it.
