Quick Answer
The standardized 16-section safety document required for every hazardous chemical on a job site.
Definition
Definition
A Safety Data Sheet (SDS) is the current OSHA-mandated format for chemical hazard communication documents, replacing the older Material Safety Data Sheet (MSDS) format under the 2012 HazCom standard aligned with GHS. SDS documents must follow a standardized 16-section format covering product identity, hazard identification, composition, first-aid measures, handling, storage, and regulatory information. Employers must ensure SDS accessibility in both physical and electronic formats.
Context
Why It Matters in Bidding
Maintaining accessible SDS documents is an OSHA HazCom requirement, and the cost of compliance — training, recordkeeping, and site access systems — is part of a contractor's general conditions and overhead that flows into bids. A weak HazCom program is a citation and liability risk, so owners and GCs increasingly verify SDS management when prequalifying subs and awarding work.
Example
Example
A safety manager assembling the project HazCom binder collects an SDS for every coating, adhesive, and fuel a sub brings on site and posts a QR-linked electronic library accessible to crews in the field.

FAQ
Questions Contractors Ask
Who is responsible for SDS on a multi-employer job site?
Each employer must maintain SDS for the chemicals it brings on site and make them accessible to its own workers, while the controlling contractor typically coordinates overall HazCom access. Subcontractors should provide their SDS to the GC. Clarifying these duties during bidding avoids gaps in the site safety program.
What is the difference between an SDS and the old MSDS?
The SDS replaced the MSDS when OSHA aligned HazCom with the globally harmonized system. The key change is a mandatory standardized 16-section format with a consistent order, which makes hazard information easier to locate quickly. Older MSDS sheets in inconsistent formats should be updated to current SDS versions.
Do SDS documents need to be on paper or can they be electronic?
Either is acceptable as long as workers have reliable, unobstructed access during all work shifts without barriers like passwords they lack or downed networks. Many contractors use electronic libraries with a paper backup. The cost of maintaining this access belongs in a contractor's general conditions and safety budget.
