Morphology
The phrase is directly compositional: it denotes the biosafety regime (biosafety) at the fourth numbered stage (level 4), so a learner who knows 'biosafety', 'level', and the numeral '4' can infer it refers to the fourth/very high stage of protective protocols. This numeric ranking pattern (noun + level + number) is a common and cross-linguistically transparent compositional structure, so the overall meaning is derivable from the parts.
Etymology
Biosafety level 4 names the highest safety category for labs. The word biosafety means protection against very dangerous living germs, and level 4 shows it is the top level with the strictest rules, strongest suits and most careful work, so it refers to the extra-strong precautions used when scientists handle viruses that have no vaccine.
