Beyond the SDS Binder: Closing the Gaps in Workplace Chemical Hazard Communication

A hazard communication program takes more than just safety data sheets and labels. Here are the gaps that cause citations and how to close them.

A worker picks up an unmarked spray bottle at the start of a shift. The safety data sheet binder sits in an office on the other side of the site, and the label on the nearest drum has worn away.

The company has all the paperwork, yet the worker cannot tell what the product does to skin or lungs. That gap between having information and being able to use it is exactly what a hazard communication program is meant to close.

A hazard communication program is the written plan an employer keeps to show how workers will learn about the chemicals they handle through labels, safety data sheets (SDS) and training.

OSHA's Hazard Communication standard, 29 CFR 1910.1200, sets the requirements for any workplace with hazardous chemicals. That covers everything from a chemical plant to an auto repair shop.

Most failures happen in the gaps between the required parts of the program: the chemical list, access to sheets, label reading, training and upkeep. This article walks through those gaps and how to close them.

What a Written Hazard Communication Program Includes

OSHA requires a written plan at each workplace that has hazardous chemicals, under 29 CFR 1910.1200. Your program is a record of how your workplace handles chemical information, not a copy of the standard.

The written program describes:

• The list of hazardous chemicals on site, by the product name used on each sheet.
• How containers are labeled.
• Where sheets are kept and how workers reach them.
• How and when workers are trained.
• How workers learn about unusual tasks and unmarked pipes.
• How contractors and other employers on the same site get the same information.

Without the chemical list, no one can say which sheets should be on file.

Where a Hazard Communication Program Usually Falls Short

Many programs fall short because they are out of date or leave people out. OSHA citation data shows where problems turn up:

Gap 1: The Program Goes Out of Date

A warehouse that switches to a new degreaser shows how this happens.

Receiving puts the drums on the floor, and the night shift starts using them. The sheet goes by email to one person, who is on leave, and the written chemical list still names the old product.

When a night worker splashes it in an eye, no one knows where the first-aid instructions are.

Gap 2: Training Leaves People Out

Programs often treat only "chemical users" as the audience, so facilities crews and other workers who handle chemicals only occasionally get missed. Contractors are a related gap: the host employer must tell other employers on site about the hazards their workers may meet. A cleaning vendor's products, for example, are hazardous chemicals in your building.

Making Safety Data Sheets and Labels Usable at the Workstation

You can still keep paper binders. OSHA requires sheets to be readily accessible during each work shift, and electronic copies are acceptable as long as they do not create barriers to immediate access.

OSHA's fact sheet on effective hazard communication programs adds a backup for power or network failures, and hard copies for medical staff in an emergency. Four steps keep sheets within reach on any shift:

1. Put access in every work area, including remote and night-shift locations.
2. Test access on the slowest device and where the network signal is weakest.
3. Plan for outages with a backup copy that workers know about.
4. Tell workers what to do and whom to call when a sheet is missing.

Sheets hold the full details, but a worker holding a container needs a warning right on it. That is the job of the label.

A shipped label has six parts: the product name, signal word, hazard statements, pictograms, precautionary statements and the supplier's name and contact details. The signal word, "Danger" or "Warning," shows how severe the hazard is, and the pictogram shows the type, such as a flame on a solvent.

Containers filled at work need their own secondary container labels. Each must give at least the product name and words or symbols that describe the general hazard. Skipping that label leaves a worker holding an unmarked bottle, unsure whether it is a solvent or a cleaner.

Training That Workers Can Use on the Job

Hazard communication training starts when a worker is first assigned to a job. According to OSHA, it repeats whenever a new chemical hazard appears in the work area. Training must be presented in a manner and language workers understand.

Delivering training on schedule is only half the job; the other half is knowing whether it worked.

A signed roster shows who attended, not what they understood. Asking a worker to explain a label, or to find a sheet on the spot, shows whether the training worked.

Training matters most for hazards that are easy to miss.

Bleach mixed with an ammonia-based cleaner releases toxic gas, and a worker who was never told has no reason to keep them apart.

A new product that adds no new type of hazard needs no new training. One that does calls for training when it arrives.

Keeping a Hazard Communication Program Current After the 2024 Update

OSHA's 2024 update aligned the standard with the seventh revision of the Globally Harmonized System (GHS), the international system for classifying and labeling chemicals. OSHA has since moved the compliance dates. Employers have two to track:

• Nov. 20, 2026, for substances (single chemicals): Update workplace labeling, the written program and training on newly identified hazards.
• May 19, 2028, for mixtures (blends of chemicals): Make the same updates.

Suppliers face their own deadlines. Their date for substances was May 19, 2026, so updated labels and sheets may already be arriving. Manufacturers, importers and distributors have until Nov. 19, 2027, to finish evaluating and relabeling mixtures.

Workers need training on newly identified hazards to read the new labels and sheets correctly. Compare each new sheet with the chemical list and add the new hazards to training.

Each program needs a named owner and a review date. The standard sets no review schedule, but OSHA's fact sheet says the program must remain current.

What Cal/OSHA Adds for California Employers

California follows section 5194 of its Code of Regulations. Cal/OSHA's hazard communication guide describes it as aligned with the federal rule. Two differences stand out:

• A new or revised sheet that shows a significantly higher risk must reach employees within 30 days of receipt, so a warning cannot sit in a drawer.
• Training must explain workers' rights under the Hazardous Substances Information and Training Act. These include protection from discrimination.

The guide lists the rest. Cal/OSHA can confirm how the 2024 federal changes apply in California.

Test One Work Area Before You Fix the Whole Program

Choose a single room or station and compare the chemicals stored there with the chemical list and the sheets on file. Then ask a worker who did not write your program to find a sheet and read a label aloud.

Every area should pass that test: The worker finds the sheet, reads the label and says what to do next.
