Hello, would you be in agreement with me that the following from SQF includes samples, meaning anyone doing laboratory testing needs to wear a hairnet, too?:
 
- SQF Code 11.4.1.2 / 17.4.1.2   Personnel working in or visiting product handling or processing operations shall ensure that:
- v. Hair restraints and beard covers, where applicable, are used in areas where product is exposed;
 
Please comment on similar requirements in GMP as well.
 
(Good Manufacturing Practices has a similar requirement.  However, because these do not mention samples specifically, we seem to have fallen into what I see as bad habits regarding hair nets and I want confirmation before I move forward.)
 
We are manufacturing dietary supplements in the United States and follow 21 CFR Parts 111 and 117, SQF, and NSF GMP.
 
Thank you,
Matthew
