Spelling Out These Legal Terms in Hazardous Drugs Regulations

If you’re reading this, then you’re one of many healthcare workers who have second guessed the meanings of should, shall, and must in FDA, OSHA, and USP <800> regulations--or other legal documents as part of your work. 

Should, Shall, Must

Each of these terms have specific meanings when used in legal documents, meanings that are a bit different than when we use the terms in everyday language. Here’s a rundown of where these legal terms appear and what they mean exactly.

Where might you see the terms should, shall, and must?
The FDA uses these terms in regulations based on the Federal Food, Drug, and Cosmetic Act (FD&C Act). Regulations such as USP <800> provide legal authority to the FDA.

Medical facilities often rely on another set of documents called “FDA guidance documents” to further explain regulations. Guidance documents do not set new legal standards or impose new requirements like regulations. Because of this, they cannot include mandatory language such as shall, must, required, or requirement, according to the Code of Federal Regulations (CFR).

What do should, shall, and must mean within USP <800> and other FDA regulations?Should means it is “better than not,” and is suggestive vs. mandatory. Should reads as a recommendation allowing the reader to make their own judgement. 

Example from USP <800> on Administering an Oral Liquid Dose : 
“Appropriate techniques and ancillary devices should be used when the dosage form allows and should be based on your healthcare facility’s protocols, procedures or SOPs.” 

In everyday English, shall is a synonym to will, may, or is. In contrast, its legal definition is definitive; it means must or mandatory. In fact, FDA regulations frequently use shall to state mandatory requirements.

Example: 
“A regulation published in accordance with §171.100(a) shall become effective upon publication in the Federal Register.” CFR §171.102  (Re-read it and replace shall with must for the intended legal meaning.)

Shall is one of the most litigated words in the English language, according to Bryan Garner, editor of Black's Law Dictionary. Garner and others object to its use because it is rarely used in conversation, and its meaning is ambiguous. In fact, Garner has proposed omitting shall from legal documents all together. As that is not the case, when you see the word shall, you can replace it with must to understand the intent.

Must is a “word of obligation” and imposes a legal obligation about a mandatory rule. Its definition in our everyday use and legal use are the same making it much easier to decipher. 

Example from USP <800> on Administering an Oral Liquid Dose : 
“Appropriate PPE must be worn based on your healthcare facility’s protocols, procedures or SOPs.” 

Summary
In summary, as you prepare for USP <800> inspections, audits by the Joint Commission, or ensure safety procedures are up-to-date, shall and must are the two terms to look out for as they require action or compliance. Should leaves room open for you to decide whether your facility follows the recommendation. 

And that concludes our grammar lesson for the day. :-) We hope this information helps you better understand the legal definitions of should, shall and must.
