Whether you manage a busy warehouse, run an auto body shop, or oversee a corporate facility, there is one OSHA standard that almost always sits at the top of an inspector’s checklist: The Hazard Communication Standard (HazCom).
At its core, HazCom is built on a simple, human principle: workers have both a right to know and a right to understand the chemical hazards they work around.
But translating that principle into daily operations can feel overwhelming. With OSHA recently updating the standard to align with newer global criteria (the Globally Harmonized System, or GHS Rev. 7) and extending key compliance deadlines into late 2026 and beyond, there is no better time to audit your facility’s safety.
The 5 Pillars of HazCom Compliance
To build an airtight HazCom program, you need to focus on five core operational areas. If any one of these pillars falls down, your compliance program does too.
1. Pinpoint Your “HazCom Champion”
Don’t let compliance fall into a black hole of shared responsibility. Assign a designated HazCom Coordinator. This person will oversee your chemical list, hunt down missing safety sheets, check container labels, and keep training logs up to date.
2. Take a Chemical Inventory
You cannot communicate a hazard if you do not know it exists. Your champion should lead a physical walk-through of your entire facility—including janitorial closets, maintenance sheds, and storage lockers.
• Document every hazardous chemical.
• Ensure the name on your master list matches the product identifier on the chemical’s label and safety sheet.
• Keep this inventory updated as you phase out old chemicals or bring in new ones.
3. Ensure Hassle-Free Access to Safety Data Sheets (SDS)
Under the GHS system, every chemical is accompanied by a standardized, 16-section Safety Data Sheet (SDS). Your legal duty as an employer is to make these documents easily accessible to your staff on every single shift.• The “Zero Barriers” Rule: An employee shouldn’t have to ask a supervisor for a key, a password, or permission to see an SDS.
• The Power Outage Test: Keeping your SDSs in a digital cloud is perfectly fine, but what happens if the internet goes down or the power cuts out? You must have a reliable backup plan (like a local drive, an offline app, or a physical binder) to ensure uninterrupted access.
4. Keep Labels Clear, Intact, and Standardized
Every hazardous chemical container must wear an easy-to-read label.
• Primary Containers: The containers that arrive directly from the manufacturer should already have compliant labels. Your only job here is to ensure those labels do not get defaced, ripped, or covered up.
• Secondary Containers: If a worker pours a chemical from a 55-gallon drum into a smaller spray bottle, that secondary bottle must be labeled. The only exception is if the employee uses the transferred chemical entirely during their own shift and keeps the container in their possession the entire time.
• GHS Label Anatomy: Modern labels must feature product identifiers, signal words (“Danger” or “Warning”), hazard and precautionary statements, and the recognizable red-bordered pictograms.
5. Deliver Practical (and Timely) Training
Training shouldn’t be a passive “slide-deck-and-nap” session. It needs to be practical. Your team must be trained before they begin working with a hazardous chemical, and whenever a new hazard is introduced to their work environment.
Effective training teaches your team:
• How to quickly spot hazards on GHS labels and where to find the corresponding SDS.
• The specific physical and health risks of the chemicals they handle.
• How to protect themselves (PPE requirements, safe handling, and proper ventilation).
• What to do in an emergency, like a spill or chemical splash.
What’s New? Crucial OSHA Timeline Updates
OSHA finalized an update to the HazCom standard to match newer international safety classifications (GHS Rev. 7).While this doesn’t change the underlying structure of SDSs or pictograms, it does introduce new hazard classifications—such as “chemicals under pressure” and revised aerosol categories.
To give businesses breathing room to digest these updates, OSHA extended the compliance deadlines by four months.
What this means for you: You don’t need to retrain your entire staff on the basics of GHS. However, as your suppliers send you updated SDSs reflecting these new classifications, you must identify if any of your chemicals have new hazard ratings and provide focused training to affected employees before the November 20, 2026 deadline.
Putting It All in Writing
If an OSHA inspector walks through your door, the very first thing they will ask for is your Written Hazard Communication Program.This document shouldn’t sit on a shelf gathering dust. It is your company’s blueprint explaining exactly how you manage inventory, who is responsible for labels, how SDS sheets are maintained, and how you inform outside contractors or temporary workers of on-site chemical hazards.
With the new transition, make sure your written plan and daily practices account for two crucial, highly specific GHS Rev. 7 updates:
• Trade Secrets Update: The GHS Rev. 7 update changes how companies claim “Trade Secrets” for chemical concentrations on SDSs. Manufacturers must now use specific, narrower concentration ranges rather than broad, generic brackets. You should expect your incoming SDSs to look a bit more detailed than before, so make sure your database managers are prepared.
• Small Container Relief: The update also introduced practical, much-needed relief for labeling tiny containers (specifically those under 100 ml and under 3 ml). This is a massive win for lab environments, R&D centers, or life sciences sectors where squeezing full GHS data onto micro-vials has historically been a logistical nightmare.
