A Safety Data Sheet (SDS) is a structured document that describes the hazards, safe handling, storage, emergency response, and regulatory information for a chemical substance or mixture. In many jurisdictions, SDS documents support hazard communication programs for workplaces that use, store, or transport chemicals.

Most modern SDS formats use 16 sections to organize chemical hazard, handling, regulatory, and composition information. Each section answers a specific operational or compliance-support question, and teams typically review the most decision-critical sections first.

AI-assisted SDS generation typically combines structured chemical inputs, hazard-classification support, and consistency checks to draft SDS sections. Responsible workflows keep human review, jurisdiction assumptions, and audit trails visible before any SDS is approved for use.

Process Safety Information (PSI) is the technical and safety information needed to understand process hazards and operate a facility safely. PSI commonly includes chemical data, process chemistry, equipment design basis, relief systems, drawings, and safeguards.

Permit-to-work (PTW) is a formal system used to control hazardous work by defining scope, hazards, isolations, authorizations, and handovers before work begins. PTW helps teams coordinate maintenance, operations, and safety controls.

The Globally Harmonized System (GHS) provides a structured approach to classifying chemical hazards and communicating them through labels and SDS documents. Classification depends on substance data, test results, and jurisdiction-specific adoption rules.

Chemical compatibility assessment evaluates whether substances can be safely stored, mixed, or handled together without dangerous reactions, container failure, or unacceptable hazard escalation. Assessment should consider chemical identity, conditions, containers, and emergency response implications.

Engineering calculation validation confirms that inputs, units, assumptions, and methods are appropriate before results are used in design or operations. Strong validation practices make calculations traceable and reviewable by qualified engineers.
