The statement about
“Crystalline solids do not have a sharp melting point” is false. Crystalline
solids are solids that have particles arranged in a regular, repeating
patterns. They are held together by uniform intermolecular forces. The faces
intersect at a specific angle that identifies that substance. They have
distinctive internal structures that in turn lead to distinctive flat surfaces.
These flat surfaces give a short rage order. When exposed to x – ray
diffractometers, they exhibit a distinctive pattern used to identify the
material. They give the same face when you turn a crystalline solid around

One of those safety measures is that "one should never use taste, touch, or smell to identify an unknown chemical".
This is so because a chemical that is unknown amounts to the fact that what such chemical contains is unknown, hence, the chemical might have the ability to cause harm or injuries to the sense organ. For example, a conc. acid that is tasted will burn the tongue etc.
