OSHA 2025 Hazard Communication Standard: What to Know Now
OSHA’s 2025 update to the Hazard Communication Standard (HCS) brings new alignment with the Globally Harmonized System (GHS) for classifying and labeling chemicals. These revisions strengthen the way contractors communicate hazards, train employees, and manage chemical documentation.
For Arizona contractors handling fuels, lubricants, cleaning products, or hydraulic fluids on jobsites, understanding these updates is critical. D&O Crane ensures full compliance by maintaining accurate labeling, up-to-date Safety Data Sheets (SDS), and clear training programs for all employees who work with hazardous materials.
What’s New in OSHA’s 2025 Hazard Communication Standard
OSHA’s revised HCS aligns with GHS Revision 7, improving hazard classification criteria and label consistency across industries. The 2025 rule adds clarity to chemical labeling, container requirements, and pictogram usage.
Employers must ensure every product label includes:
- Product identifier
- Signal word (Danger or Warning)
- Hazard statements
- Precautionary statements
- Supplier information

Safety Data Sheets (SDS) and Recordkeeping
Under the 2025 update, employers must maintain current Safety Data Sheets (SDS) for every chemical used, stored, or transported. SDS documents must remain readily available to all employees at all times.
MSHA requires similar documentation for mine and quarry operations, meaning dual compliance may apply for contractors in those industries.
D&O Crane maintains centralized digital access to all Safety Data Sheets. This ensures workers and inspectors can quickly retrieve information about chemical properties, exposure risks, and emergency response actions.
Employee Training Requirements
The updated standard requires initial and ongoing training for all employees exposed to hazardous materials. Training must cover labeling interpretation, SDS review, and safe handling procedures.
D&O Crane conducts regular hazard communication training through certified programs. Crews learn how to read labels, identify pictograms, and follow proper PPE and spill response procedures. Employers can learn more about OSHA’s training criteria at OSHA Training Requirements.
Labeling and Secondary Containers
Employers must also label all secondary containers, such as spray bottles or small transfer containers, with clear hazard identifiers. Unlabeled or misidentified containers are among the most common HAZCOM violations cited by OSHA.
D&O Crane uses pre-printed secondary container labels that match OSHA’s GHS formatting, reducing confusion and ensuring every chemical remains traceable from source to use.

Contractor Responsibilities and Multi-Employer Sites
On shared worksites, employers must coordinate to ensure all crews understand on-site hazards. The 2025 rule expands communication responsibilities, requiring general contractors and subcontractors to share SDSs and label information before work begins.
D&O Crane integrates these requirements into its pre-lift safety meetings and jobsite coordination plans. This proactive approach ensures compliance even on complex, multi-contractor projects.
Why Compliance Matters
Noncompliance with OSHA’s Hazard Communication Standard remains one of the most frequently cited violations nationwide. Beyond penalties, poor labeling and training can lead to serious injuries or chemical exposure incidents.
By maintaining organized records, visible labels, and consistent training, contractors protect both their teams and their reputation.
