What the standard requires
Any employer with hazardous chemicals in the workplace must comply with 29 CFR 1910.1200 — the Hazard Communication Standard, better known as HazCom or the "Right to Know" standard. Aligned with the UN's Globally Harmonized System (GHS) since 2012, HazCom is arguably the most far-reaching OSHA standard: it applies to nearly every workplace, including offices where cleaning chemicals are used.
The standard has five core components: (1) a written HazCom program, (2) a chemical inventory, (3) GHS-compliant container labels, (4) Safety Data Sheets (SDSs) for every hazardous chemical, and (5) employee information and training.
Who it applies to
Every general-industry, construction, maritime, and agricultural employer whose workplace contains hazardous chemicals — including consumer products used in a manner that exceeds normal consumer use. Small quantities do not exempt an employer. A single quart of paint thinner in a maintenance closet triggers the standard.
Chemical manufacturers, importers, and distributors have additional upstream duties: they must classify chemical hazards, prepare labels and SDSs, and transmit them to downstream customers.
Employer duties
1. Written HazCom program
OSHA requires a site-specific written program describing how you implement each element of the standard. Templates are widely available, but a generic binder that doesn't reference your actual chemicals, your actual labeling system, or your actual training procedures is a citation waiting to happen. The program must address:
- Container labeling procedures (including secondary containers).
- SDS management — where they are, how employees access them, how they're updated.
- Employee training procedures.
- Methods for informing employees of non-routine tasks and multi-employer worksites.
- A list of hazardous chemicals present.
2. Chemical inventory
Maintain a current list of all hazardous chemicals known to be present in the workplace, identified in a way that cross-references the corresponding SDS. Review and update whenever a new chemical is introduced or an existing one is discontinued.
3. GHS-compliant container labels
Every original manufacturer container must have a label with six elements: product identifier, signal word (Danger or Warning), pictograms, hazard statements, precautionary statements, and supplier information. Do not deface or remove these labels.
Secondary containers (a spray bottle of degreaser filled from a bulk drum, for example) require a label with the product identifier and hazard information — either a duplicate GHS label or an equivalent (words, pictures, symbols) that conveys the hazards. The only exception: an immediate-use container that is under the control of the employee who filled it and emptied by the end of that employee's shift.
4. Safety Data Sheets (SDSs)
Every hazardous chemical needs a current 16-section SDS in the standardized GHS format. SDSs must be readily accessible to employees in their work area during each work shift — that means during all shifts you operate, not just first shift. A binder in a locked office fails the test. Electronic access is acceptable if employees have reliable devices, know how to use the system, and have a backup for power/network outages.
5. Employee training
Every employee exposed to hazardous chemicals must receive training at initial assignment and whenever a new hazard is introduced. Training must cover:
- Requirements of the HazCom Standard.
- Chemicals present in the work area and their hazards.
- How to detect the presence or release of a hazardous chemical.
- Protective measures — engineering controls, safe work practices, PPE.
- How to read GHS labels and SDSs.
- Details of the employer's written program and how to access SDSs.
Common citations
Year after year, HazCom is one of OSHA's top three most-cited standards. The paragraphs cited most often:
- 1910.1200(e)(1) — no written HazCom program.
- 1910.1200(h)(1) — inadequate or missing employee training.
- 1910.1200(g)(1) — missing or outdated Safety Data Sheets.
- 1910.1200(f)(6) — improperly labeled secondary containers.
- 1910.1200(e)(1)(i) — chemical inventory not maintained.
Documentation checklist
- Written HazCom program (site-specific, current, reviewed annually).
- Current chemical inventory keyed to the SDS library.
- SDS library accessible during all shifts (paper or electronic).
- Container labeling procedures for secondary containers.
- Training records: date, content, trainer, employee signature, chemicals covered.
- Non-routine task and multi-employer worksite procedures.
Common mistakes we see
- A generic template with no site-specific detail. "See attached list" with no attached list. OSHA reads these.
- Missing SDSs for chemicals that have been on-site for years. An easy catch on a walkthrough — the inspector picks a random label and asks to see the SDS.
- Spray bottles with no labels. "Everyone knows what's in it" fails every time.
- Training records that don't identify the chemicals or the standard covered. A generic "safety training" sign-in sheet doesn't prove HazCom compliance.
How CSPC helps
Our Baseline Blueprint engagement includes a full HazCom program audit: chemical inventory reconciliation, SDS library review, label spot-check, and training-record gap analysis. For ongoing management, our Compliance Compass program keeps the written program, inventory, and SDS library current and delivers refresher training on a documented schedule.
