Where Should SDS Be Kept at Work, and How Many Binders Do You Need?
Short answer: OSHA does not set a number of binders. It requires that safety data sheets be readily accessible to employees during each work shift while they are in their work areas (29 CFR 1910.1200(g)(8)). One binder can be enough for a single small site; separate areas, buildings or shifts without access to it need their own copy or a reliable electronic option.

What "readily accessible" means
- During every shift: a binder in a locked office that night staff cannot open does not count.
- In or near the work area: employees should be able to get to the sheet without leaving their area for long or asking permission.
- No barriers: no passwords staff do not know, no manager who must be found first.
How many binders do you need?
As many as it takes for every employee to reach the sheets during their shift. Some common setups:
- One room or small shop, one shift: one binder in a known, central spot (often near the main chemical storage or the break room) is usually enough.
- Several buildings, floors or departments: a binder in each area, or one binder per area covering the chemicals used there, plus a master copy.
- Mobile crews: OSHA allows SDSs for employees who travel between workplaces during a shift to be kept at the primary workplace facility, as long as employees can get the information immediately in an emergency (29 CFR 1910.1200(g)(9)). Many crews keep a copy in the vehicle or on a phone.
Is digital access allowed?
Yes. OSHA allows electronic access (a computer, tablet or app) instead of paper as long as there are no barriers to immediate access in each workplace, and employees know how to use it. Have a back-up for power or network outages; a printed index or emergency copy is the usual answer. See OSHA safety data sheet requirements.
Make sure staff know where they are
Telling employees where the SDSs are kept, and how to read them, is part of HazCom training. A sign on the storage room door or a QR code poster pointing to the digital library helps employees find them on any shift.
Frequently asked questions
Where should safety data sheets be kept?
Somewhere employees can reach them during every shift while in their work areas, without barriers: commonly a binder in a central, unlocked spot near chemical storage, or an electronic library with a back-up.
How many SDS binders do I need?
OSHA sets no number. You need enough copies, or reliable electronic access, for every employee to reach the sheets during their shift in their work area. Separate buildings, departments or shifts often need separate copies.
Can SDSs be kept electronically?
Yes, as long as employees have immediate access with no barriers in each workplace and there is a back-up plan for outages.
Where can you find SDS in the workplace?
Ask your supervisor or check your HazCom training: employers must keep SDSs readily accessible and tell employees where they are, often in a binder near chemical storage or in an SDS app.
Most SDS software stops at the safety data sheets. OSHA HazCom asks an employer for five things: a written program, a chemical list, container labels, SDS access and employee training. SDSentry covers all five in one product and builds the written program from your own chemical list. See how 11 SDS tools compare on all five →
