Morphology
The phrase is transparently compositionally built from 'biosafety' + 'level' + 'three', so a learner who knows those words can infer it denotes the third tier or category of biosafety protocols. However, the precise scope and technical implications (e.g., respiratory transmission, severity, specific containment practices) require specialist domain knowledge beyond a general B1 learner, so the meaning is not fully predictable.
Etymology
Biosafety level 3 comes from a numbered system for labs: biosafety means 'safety rules' and level is like a 'floor number' that shows how strict those rules are. So biosafety level 3 refers to the strong safety steps, such as sealed rooms, special masks, and filtered air, used when scientists work with germs that spread through the air and can make people very sick.
