Safety is not an add-on; it is a design constraint. In the context of design drawings, safety operates on three levels:
How will the worker build this? Does the drawing account for fall protection (e.g., anchor points)? Does it specify non-toxic adhesives? A safe drawing includes notes on safe assembly sequences (e.g., "Weld base plate before attaching top frame"). Safety is not an add-on; it is a design constraint
Drawings must highlight moving parts, pinch points, electrical insulation, and emergency stops. In product design, a drawing should specify rounded corners over sharp edges to prevent laceration. Does it specify non-toxic adhesives
A drawing must indicate load capacities, material strengths, and stress points. For example, a drawing for a pedestrian bridge must clearly show the maximum live load. Failure to do so leads to collapse. In product design, a drawing should specify rounded
