Why a general contractor needs subcontractor SDSs
On a multi-employer construction site, the chemicals that injure a worker are often someone else's — a painter's solvents, a roofer's adhesives, a mason's curing compounds. OSHA can still cite the controlling employer (usually the general contractor) for those hazards under its Multi-Employer Citation Policy CPL 02-00-124 — but only to the extent of reasonable care, not strict liability. The federal courts have upheld that doctrine (Acosta v. Hensel Phelps Construction Co., 909 F.3d 723, 5th Cir. 2018). A documented written request for each sub's HazCom records is one element of reasonable care — the policy also looks at how often you inspect, how promptly you correct hazards, and whether you enforce compliance with follow-up inspections — and it is what this tool produces.
The standard of care is deliberately not the same as the sub's. As the regulatory source of truth puts it: a controlling employer is held to reasonable care — not the same degree of care as the employer that created or is exposed to the hazard. So you are not expected to be perfect; you are expected to ask, document, and follow up.
What to request from each subcontractor
These are the core Hazard Communication documents the tool can request. Each is tied to the paragraph of the HazCom standard (29 CFR 1926.59 (adopts 29 CFR 1910.1200)) it relates to; where the standard does not itself require the document (training records), the row says so.
| Document | Related rule |
|---|---|
| Written Hazard Communication program | 29 CFR 1910.1200(e) |
| Safety Data Sheets (SDS) for every chemical brought on site | 29 CFR 1910.1200(g)(8) |
| Chemical inventory / list of hazardous chemicals | 29 CFR 1910.1200(e)(1)(i) |
| Employee HazCom training records (dates, topics, attendees) | Best practice — 29 CFR 1910.1200(h) requires the training, not a record |
| Container / secondary-container labeling confirmation (GHS) | 29 CFR 1910.1200(f) |
| Name of the on-site person responsible for HazCom | 29 CFR 1910.1200(e)(1) |
Safety Data Sheets must be readily accessible to workers during each shift 29 CFR 1910.1200(g)(8). Manufacturers and importers must bring the SDSs for substances to HCS 2024 by May 19, 2026 and those for mixtures by November 19, 2027; the November 20, 2026 date is the employers' date to update workplace labeling, the written program and training as necessary.
Escalate in writing — initial, second, final
Reasonable care is a process, not a single email. If a sub does not respond, the paper trail you build is what demonstrates diligence. This tool produces three escalation levels with the right tone for each:
| Level | When to use it | What it says |
|---|---|---|
| Initial request | Before the sub mobilizes or as soon as chemicals arrive on site. | Professional ask; offers help to get compliant. |
| Second notice | No (or incomplete) response by the first deadline. | Warns that affected chemical work may be restricted until resolved. |
| Final notice | Still no compliant documentation after the second notice. | States the sub's chemical work will be suspended; documents the file. |
Worked examples
Example 1 — Painter brings solvents, no paperwork. A painting sub mobilizes Monday with no SDSs on site. You send an initial request for the written program, SDSs, and training records with a 5 business-day window. Sent Monday June 1, the computed respond-by date is Monday June 8 (weekends skipped). You file the dated request in your project safety folder.
Example 2 — Spanish-speaking crew, no response. The deadline passes with no reply and the sub's foreman speaks Spanish. You send a second notice in bilingual mode so both the office and the foreman understand it, warning that the affected chemical work may be paused. If that also goes unanswered, the final notice states the chemical work will be suspended — and your three dated, documented requests are now part of the record of reasonable care if OSHA ever inspects, next to your site inspections and the corrections that followed.
What to do after you send it
- Review the SDSs you get back — confirm they cover the chemicals actually on site and are current.
- Check site labeling — containers and secondary containers must be labeled 29 CFR 1910.1200(f).
- Make hazard info accessible during each shift 29 CFR 1910.1200(g)(8).
- Document the gaps and your action — if the sub won't comply, restrict the work and record why. That record is the point.
Frequently asked questions
Can a general contractor really be cited for a subcontractor's HazCom violation?
Yes — but only to the extent of reasonable care, not strict liability. Under OSHA's Multi-Employer Citation Policy (CPL 02-00-124), a controlling employer (typically the GC) can be cited for a hazard created or controlled by a sub if it failed to exercise reasonable care to detect and correct it. The federal courts have upheld this (Acosta v. Hensel Phelps, 909 F.3d 723, 5th Cir. 2018). OSHA does not hold the GC to the same degree of care as the employer that created or is exposed to the hazard. A documented request like this RFI is one element of that reasonable care; the directive also looks at whether you inspect at appropriate intervals, correct hazards promptly, and enforce compliance with follow-up inspections.
When should I send this RFI?
Before the sub mobilizes, or immediately after they bring chemicals on site. Verify they have a written HazCom program, Safety Data Sheets for the chemicals they bring, container/secondary-container labels, and documented training. Request anything missing in writing and keep a dated copy — that paper trail is the point.
What if the subcontractor never responds?
Escalate in writing. Use the 'second notice' and 'final notice' levels in this tool, each with a documented deadline. If the sub still will not produce compliant documentation, reasonable care may require you to restrict the chemical work or remove them from the project until they comply. Keep every request, the lack of response, and the corrective action you took — that record is part of what demonstrates reasonable diligence if OSHA inspects.
Why is the deadline measured in business days?
Business days (Monday–Friday, excluding weekends) are the customary standard for documentation requests on a project and set a clear, defensible response window. This tool computes the calendar 'respond-by' date by counting forward the number of business days you choose, skipping Saturdays and Sundays. It does not subtract individual federal holidays, so on a holiday week give a little extra time.
Does this RFI prove I'm compliant?
It documents that you requested the information — an important piece of reasonable care — but it is not, by itself, proof of compliance. You still must act on the response: review the SDSs, confirm site labeling, make hazard information accessible during each shift (29 CFR 1910.1200(g)(8)), and follow up on anything missing. This tool generates a template and is not legal advice; consult qualified counsel for worksite-specific questions.
Is the Spanish version OSHA-acceptable?
OSHA requires that hazard information be communicated effectively to employees, and a large share of the construction workforce speaks Spanish. Providing the request bilingually helps ensure the sub's foreman and crew actually understand what is being asked and supports the broader HazCom requirement to train workers in a language and at a literacy level they comprehend. The bilingual PDF puts both languages on one filed record.
