HazCom Program Duties: Inventory, Labels and Contractors
Run a Hazard Communication program that matches the floor, with a real chemical list, correct workplace labels, SDS access on every shift, and clear duties toward contractors and temp workers.
Table of contents
Most Hazard Communication (HazCom) failures have nothing to do with chemistry. The binder lists products the site stopped buying years ago, a spray bottle has no label, the night shift cannot get to the SDS, and the contractor on the roof was told nothing. OSHA's standard, 29 CFR 1910.1200, is mostly about whether information reaches people. This is for leads, supervisors and safety coordinators who keep a program running, not just workers who follow it. The focus here is general industry, and construction employers follow the same standard through 1926.59. State plans can differ, and your employer's program has the final word on how things work at your site.
What You Will Be Able to Do
- List what a written HazCom program must include.
- Build a chemical list that matches what is really on site.
- Say what the standard does not cover, including the consumer product exemption.
- Apply the workplace labeling rules to real containers.
- Set up SDS access that works on every shift.
- Meet your duties toward contractors and temp workers.
What the Written Program Must Contain
Under 1910.1200(e)(1), the employer has to develop, implement and maintain a written program at each workplace.
| Part | What it covers | Paragraph |
|---|---|---|
| Labels | How containers get labeled | (e)(1), (f) |
| Safety data sheets | How sheets are kept and reached | (e)(1), (g) |
| Training | How workers get information and training | (e)(1), (h) |
| Chemical list | Hazardous chemicals known to be present, by product identifier | (e)(1)(i) |
| Non-routine tasks | How workers learn the hazards of jobs such as cleaning a reactor vessel | (e)(1)(ii) |
| Unlabeled pipes | How workers learn what is in pipes in their work area | (e)(1)(ii) |
| Other employers | How you share information on multi-employer sites | (e)(2) |
The program has to be available on request to employees, their representatives and OSHA. If workers travel between sites during a shift, it can be kept at the main facility.
A template is a start, not a program. If it names a safety manager who left, or describes labels your site does not use, it does not describe how the criteria "will be met." The word "implement" matters. An inspector will compare the paper with the floor.
Worked example: A maintenance crew is about to cut into a pipe with no marking, in a part of a plant they rarely visit. The program has to say how they find out what is inside and what its hazards are. A workable answer names who to ask, how the line gets identified, and how that gets to the crew before the job starts. "Ask around" is not a method.
Build the Chemical List
A hazardous chemical is any chemical classified as a physical or health hazard, a simple asphyxiant, a combustible dust, or a hazard not otherwise classified. A simple asphyxiant is a gas that pushes oxygen out of the air, such as the argon in a welding shop. Do not forget dusts, gases and the products that sit on carts and in trucks.
The list can cover the whole workplace or each work area. Use the same product identifier that is on the label and the SDS, so that anyone can trace one to the other.
- Walk every area. Include closets, roofs, service trucks, kitchens, labs and the shelf behind the supervisor's desk.
- Record what the label says. Copy the product name exactly, plus the supplier and location.
- Match each item to its SDS. Flag anything without one.
- Flag anything without a readable label.
- Clear out what you no longer use, through your waste process.
- Put a gate on new products. Tie the list to purchasing, so that a new product cannot arrive unseen.
| Area | Product identifier | Supplier | SDS on file? |
|---|---|---|---|
| Paint booth | Topcoat Clear 2100 | Example Coatings | Yes |
| Paint booth | Reducer Fast 40 | Example Coatings | Missing, request it |
| Boiler room | Scale Remover Liquid | Example Water Care | Yes, dated 2014, check for update |
| Weld bay | Argon, compressed | Example Gas | Yes |
Worked example: A plant's old list shows 62 products. A walk of the site finds 71 on the floor. Nine products are new and were never listed. Fourteen listed products are gone. Three containers have no readable label. The plant now has 9 items to add, 14 to retire from the list, and 3 containers to identify before anyone uses them. It also has a clear sign that nothing is checking new purchases.
What the Standard Does Not Cover
The standard has limits. These are the ones that come up most.
| Item | Why it is outside or limited | Watch for |
|---|---|---|
| Consumer products used as a consumer would | Exempt if the employer can show the use, how long and how often match what a consumer would do | A worker using it all shift is covered |
| Articles | Shaped items that release only very small amounts in normal use | Cutting, grinding or welding can change that |
| Hazardous waste regulated under RCRA | Covered by other rules | Workers still need protection under those rules |
| Office workers with only isolated contact | Not "employees" for this rule | A copy tech who services toner often may be covered |
| Retail drugs and cosmetics for personal use | Listed exemptions | Bulk or process use is different |
Two kinds of workplace get limited duties. Labs have to keep labels on incoming containers, keep the sheets they receive and train workers. Warehouses and stores that only handle sealed containers must keep labels in place, keep sheets on hand or get them when asked, and train workers for a spill or leak.
The Consumer Product Test
The burden is on the employer. Having bought a product at a hardware store does not settle it.
| Worker | Product | How it is used | Likely answer |
|---|---|---|---|
| Receptionist | Window spray | Wipes a desk once a week | Exempt |
| Custodian | The same window spray | Sprays for hours every shift | Covered |
| Mechanic | Brake cleaner from a parts store | Many times a day | Covered |
| Office manager | Dish soap | Washes a coffee pot | Exempt |
Workplace Labels
Under (f)(6), each container of a hazardous chemical in the workplace needs one of two things. It can carry the same information as a shipped label. Or it can show the product identifier, plus words, pictures or symbols that give at least general information about the hazards. That second option only works when the other information workers have on hand gives them the specifics.
| Container | Is a label needed? | Paragraph |
|---|---|---|
| Original drum from the supplier | Keep the shipped label, and do not deface it | (f)(9) |
| Spray bottle filled for a coworker | Yes | (f)(6) |
| Bucket you fill and use yourself, in that shift | No, if it stays with you and only you use it | (f)(8) |
| Bucket left for the next shift | Yes | (f)(6) |
| Mix tank or other stationary vessel | A sign, placard, batch ticket or procedure can replace a label | (f)(7) |
| Container with a peeling or faded label | Fix it right away | (f)(9), (f)(10) |
"Immediate use" has a strict meaning. The chemical stays under the control of the person who transferred it, only that person uses it, and it is used within the same shift. If any one of those fails, the container needs a label.
Labels have to be legible, in English, and prominently displayed. If your workers speak other languages, you may add those, as long as the English is there too.
If you learn of significant new hazard information, a label you prepare has to be updated within six months. Makers have the same duty for what they ship.
SDS Access That Works
The employer has to keep a sheet for each hazardous chemical and make sure it is readily accessible during each work shift to workers in their work area. Electronic access is allowed, as long as it creates no barrier to immediate access. Workers who travel during a shift can have their sheets kept at the main facility, but the employer has to make sure they can get the information immediately in an emergency.
| Setup | The barrier | Fix |
|---|---|---|
| Binder in a locked office | Night shift has no key | Keep it in the work area |
| Online system with a manager's login | Workers cannot get in | Give shared or open access |
| Phone app in a basement | No signal | Add a station or backup copy |
| Desktop PC only | Fails when power or network goes down | Have a backup plan |
Test it. Go to a work area on the worst shift, name a product, and ask a worker to pull up its sheet. If they have to find a manager, you have a barrier.
If a sheet is missing for a labeled hazardous chemical, the employer must get it as soon as possible. Do not throw away old sheets without thinking. Under 1910.1020(d)(1)(ii)(B), sheets do not have to be kept for a set time, as long as some record of the chemical's identity, where it was used and when it was used is kept for at least 30 years.
Training Duties
Workers must get effective information and training at the time of their first assignment, and whenever a new chemical hazard that they have not been trained on comes into their work area. Training can cover categories of hazards, such as flammability, or specific chemicals.
What they must be told:
- What the standard requires.
- Where hazardous chemicals are present in their work area.
- Where the written program, the chemical list and the sheets are.
What training must include:
- How to detect the presence or release of a chemical, such as monitors, appearance or odor.
- The hazards of the chemicals in their area.
- How to protect themselves, including work practices, emergency procedures and PPE.
- The details of the program, including labels and how to use a sheet.
Worked example: A shop swaps one flammable solvent for another. Workers were already trained on flammable liquids as a category, so the hazard is not new. The list and the sheets still have to be updated. Later, the shop brings in a coating with a skin sensitizer, which they have never dealt with. That is a new hazard, so they get trained when it comes into their area.
The standard sets no yearly refresher, though your program may. What it does require is that training be effective. OSHA's position is that training has to be presented in a way workers are capable of understanding. A video in a language someone does not read does not meet that, and neither does a sign-in sheet on its own. An inspector can simply ask a worker where the sheets are.
Contractors and Other Employers
Under (e)(2), an employer that produces, uses or stores hazardous chemicals in a way that may expose another employer's workers has to add three things to its program:
- How the other employer gets access to the sheets.
- How that employer is told about precautions, in normal operations and foreseeable emergencies.
- How that employer is told about the labeling system.
That duty runs in every direction. It falls on whoever brings or keeps the chemical.
| Who has the chemical | Who may be exposed | Example |
|---|---|---|
| The host | The contractor's crew | Ammonia system at a food plant, with a painting crew nearby |
| The contractor | The host's workers | Roofing adhesive fumes reaching a hospital's air intakes |
| One contractor | Another contractor | A floor coating crew and electricians on one job |
Worked example: A food plant hires a welding contractor to repair a rack beside an ammonia line.
- Before the work, the plant shows the contractor how to get the sheets for ammonia and for the sanitizers used in the area.
- The plant explains its alarms, where to go, and what to do in a leak.
- The plant explains how its pipes and containers are marked.
- The contractor gives the plant access to the sheets for its own gases and rods.
- The contractor tells the plant what fumes the work will create, so that nearby workers can be protected.
- Both record what was shared, as their programs require.
Temp Workers
An OSHA letter from 2012 says both the staffing agency and the host employer are responsible for making sure temp workers are informed and trained. The host holds the primary responsibility, because it uses the chemicals and controls the hazards. The agency, at a minimum, is expected to tell workers about the standard's requirements. A contract can divide the tasks, but the host cannot assume the agency covered what only the host can know.
Compliance Dates
OSHA updated the standard in 2024, and later extended the dates. The changes come in stages.
| Who | Substances | Mixtures |
|---|---|---|
| Makers, importers and distributors | May 19, 2026 | November 19, 2027 |
| Employers | November 20, 2026 | May 19, 2028 |
For employers, the task is to update alternative workplace labels, the program and training as needed for newly identified hazards. During the transition, the rule allows compliance with either the current version or the earlier one. Check OSHA's site for changes before you plan around these dates. When a revised sheet arrives, read what changed, and do not just swap the old one out.
HazCom Is Not Your Only Chemical Training
| Training | Who needs it | How often | Rule |
|---|---|---|---|
| HazCom | Workers exposed in normal work or foreseeable emergencies | First assignment, and for new hazards | 1910.1200(h) |
| HAZWOPER | Emergency responders, and hazardous waste site and TSD workers | Yearly refresher | 1910.120 |
| DOT hazmat | Workers whose jobs affect the safety of hazmat shipments, such as loading or marking | At least every 3 years | 49 CFR 172.704 |
| Respirator | Workers required to wear one | At least yearly | 1910.134(k) |
A worker who loads drums onto a truck may need more than one of these. HazCom training alone does not cover a DOT job, or a spill response role.
Audit Your Own Program
This is not a required step, but it finds problems before an inspector does.
- Pick five containers on the floor, and trace each to the list and the sheet.
- Pick five items from the list, and find them on the floor.
- Look for unlabeled bottles, buckets and pails.
- Ask a worker on each shift to find a sheet.
- Ask a worker what a pictogram on a nearby drum means.
- Pull the file on your last contractor job.
- Compare recent purchases with the list.
Common Mistakes
| Mistake | What it costs | Better habit |
|---|---|---|
| Downloading a template and stopping | Paper that does not match the site | Write down how your site really does it |
| Assuming store-bought means exempt | Workers go untrained | Apply the use, duration and frequency test |
| Calling every bottle immediate use | Unknown bottles on carts | Test all three conditions |
| Locking up the binder | No access on nights | Test on the worst shift |
| Telling contractors nothing | Other crews exposed | Share sheets, precautions and labels |
| Relying on the agency to train temps | Site hazards never explained | The host covers what it controls |
Check Your Understanding
1. A new supervisor finds a binder from 2016. It lists 40 products, and a walk finds many that are not in it. Is the site's program in place?
Not really. The list must cover hazardous chemicals known to be present. Update it, and set up a way to catch new products.
2. A fixed mix tank has no label, but a batch ticket beside it names the tank, the product and its hazards. Is that allowed?
Yes. For a stationary vessel, a batch ticket can replace a label, as long as it identifies the container and gives the required information.
3. A service tech spends each shift at customers' sites. Where can his sheets be kept?
At the main facility, as long as he can get the information immediately in an emergency.
4. Your plant marks its containers with a color code. A painting contractor arrives tomorrow. What do you have to do about that code?
Tell the contractor about your labeling system, so their crew can read your containers.
5. A shop adds a new product with the same hazards workers were already trained on. Is new HazCom training required?
Not if the training covered that hazard category. Update the list and the sheet, and make sure workers know the new product is there.
Key Takeaways
- The written program has to match the floor, and it includes a chemical list and methods for non-routine tasks and unlabeled pipes.
- Use one product identifier across the label, the sheet and the list.
- The consumer product exemption depends on how the product is used, and the employer has to show it.
- A container only skips a label if one person fills it and uses it within the shift.
- Sheets must be reachable on every shift, with no barrier.
- On shared sites, whoever brings the chemical shares the sheets, the precautions and the labeling system.
