Does drop box allow 50+ sign ins from one account to view an SOP folder?
No. Sharing account credentials is a violation of the terms and could result in the account and all content being deleted. Aside from Business Team account accounts, a Dropbox account is intended for an individual.
The proper way to do that would be to have each technician have their own account, and you could invite them all to a shared folder that contains your SOPs. Provided that the content is less than 2GB, they would only need a free Basic account to access the shared folder.
