3.1 Getting sheets, keeping them, and the three-month clock
A label is a summary you can read at arm's length. A safety data sheet is the full account — sixteen numbered sections, in a fixed order, for every hazardous chemical in your workplace. This chapter covers how sheets arrive, how they are kept, how fast they have to change, and the one word in paragraph (g)(8) that decides most disputes: accessible.
1 Who makes one, and who has to hold one
Paragraph (g)(1) splits the duty. Chemical manufacturers and importers shall obtain or develop a safety data sheet for each hazardous chemical they produce or import. Employers shall have a safety data sheet in the workplace for each hazardous chemical which they use.
The employer's duty is to have, not to write. And notice the trigger: each hazardous chemical they use. That is a different set from everything in the building — but read it against the scope sentence at (b)(2), which reaches any chemical present so that employees may be exposed under normal conditions of use or in a foreseeable emergency. Product sitting in storage is in scope.
Paragraph (g)(2) then fixes the format, which is the subject of the next two chapters: the sheet must be in English, and must include at least the listed section numbers and headings, and the associated information under each heading, in the order listed. The employer may also keep copies in other languages.
2 How sheets arrive — and what to do when they do not
Paragraph (g)(6) sets the manufacturer and importer duty: they shall ensure that distributors and employers are provided an appropriate safety data sheet with their initial shipment, and with the first shipment after a safety data sheet is updated. Sheets may travel with the shipped containers, or be sent to the distributor or employer prior to or at the time of shipment. Paragraph (g)(6)(iv) adds that they shall also provide a sheet upon request.
Paragraph (g)(7) does the same for distributors, and adds the retail rules: a retail distributor selling to employers with a commercial account provides a sheet on request and posts a sign or otherwise informs them one is available; a wholesale distributor selling over the counter may provide the sheet on request at the time of purchase and shall post a sign or otherwise inform employers one is available; and where an employer without a commercial account buys from a retail distributor not required to hold sheets, that distributor shall provide, on request, the name, address and telephone number of the manufacturer, importer or distributor from which a sheet can be obtained.
And when nothing arrives? Paragraph (g)(6)(iii): if the safety data sheet is not provided with a shipment that has been labeled as a hazardous chemical, the distributor or employer shall obtain one from the chemical manufacturer or importer as soon as possible. The move is yours. Waiting is not a strategy the standard offers.
3 “Readily accessible during each work shift”
Paragraph (g)(8) is the operative sentence, and it is worth learning close to verbatim: the employer shall maintain in the workplace copies of the required safety data sheets for each hazardous chemical, and shall ensure that they are readily accessible during each work shift to employees when they are in their work area(s). The parenthetical that follows is the modern part: electronic access and other alternatives to maintaining paper copies of the safety data sheets are permitted as long as no barriers to immediate employee access in each workplace are created by such options.
Three tests are packed into that. Each work shift — if the office holding the binder is locked at 6 p.m., the night shift has no access. In their work areas — not in a building across the yard. No barriers to immediate access — a tablet is fine; a tablet with no signal in the basement is a barrier, and so is a password nobody on the crew has.
Paragraph (g)(9) handles mobile work: where employees travel between workplaces during a shift, the sheets may be kept at the primary workplace facility — and in that situation the employer shall ensure that employees can immediately obtain the required information in an emergency. That last clause is the price of the concession, and it usually means a phone number that is answered.
Paragraph (g)(11) extends the audience: sheets shall also be made readily available, upon request, to designated representatives, the Assistant Secretary and the Director, in accordance with 1910.1020(e).
4 Form, grouping and gaps
Paragraph (g)(10) is more permissive than most people expect. Safety data sheets may be kept in any form, including as operating procedures, and may be stored to cover groups of hazardous chemicals in a work area where it may be more appropriate to address the hazards of a process rather than individual chemicals. The condition follows immediately: in all cases the required information must be provided for each hazardous chemical and remain readily accessible during each work shift.
Paragraph (g)(4) allows one more consolidation, on the supplier side: where complex mixtures have similar hazards and contents — the ingredients are essentially the same but the specific composition varies from mixture to mixture — one sheet may be prepared to apply to all of them.
And paragraph (g)(3) governs empty space: if no relevant information is found for any sub-heading within a section, the person preparing the sheet shall mark it to indicate that no applicable information was found. A blank line is not compliant; “no data available” is. That is a useful reading habit — a genuinely empty sub-heading on a sheet is a defect worth querying with the supplier.
5 The three-month update rule
Paragraph (g)(5) carries two duties. First, accuracy: the manufacturer, importer or employer preparing the sheet shall ensure that the information provided accurately reflects the scientific evidence used in making the hazard classification.
Second, currency: if they become newly aware of any significant information regarding the hazards of a chemical, or ways to protect against the hazards, this new information shall be added to the safety data sheet within three months. If the chemical is not currently being produced or imported, the information is added before it is introduced into the workplace again.
Set that beside the label clock from Chapter 2.1 and the design becomes clear.
| Document | Deadline after becoming newly aware | Paragraph |
|---|---|---|
| Safety data sheet | Three months | (g)(5) |
| Label | Six months, with an option to supply the updated label per container for stock awaiting distribution | (f)(11)(i) |
The sheet moves first. During the window between the two, the sheet in your binder can legitimately carry information the can in your hand does not — another reason the sheet is the reference document for a decision.
6 Building a sheet system that actually works
The three failures that account for most citations are all logistical, not technical.
- 1The missing sheet. Fix at receiving: no sheet, no shelf. Log the request the same day under (g)(6)(iii).
- 2The unreachable sheet. Test it the way an inspector will: ask a worker on the least-supported shift to produce the sheet for a product in their area, in under a couple of minutes, without phoning a manager. If the answer involves a key or a password they do not have, you have a barrier under (g)(8).
- 3The unfindable sheet. Index by the product identifier from the sheet — the same string that is on the label under Appendix C.1 and on the chemical list under (e)(1)(i). One identifier, three documents.
Do those three and the rest of Part 3 becomes what it should be: reading the sheet you already have, in the sixteen sections the next two chapters walk through.
- Manufacturers and importers develop sheets; employers must have one for each hazardous chemical they use.
- If a labeled hazardous chemical arrives without a sheet, the receiver must obtain one as soon as possible.
- Sheets must be readily accessible during each work shift, in employees' work areas, with no barrier to immediate access.
- Electronic access is expressly permitted; a dead signal, a locked door or an unshared password is a barrier.
- Sheets may be kept in any form and may cover groups of chemicals, provided the required information stays available for each chemical.
- Significant new information goes on the sheet within three months, and on the label within six.
