OSHA Safety Data Sheets (SDS) Guide: Complete Employer Compliance Guide

Safety Data Sheets (SDSs) are one of the most important components of OSHA's Hazard Communication Standard (HazCom). They provide employees with detailed information about hazardous chemicals, including safe handling procedures, emergency response information, health hazards, storage requirements, and first aid measures.

Every employer that uses hazardous chemicals should understand OSHA's SDS requirements to help protect employees and maintain workplace compliance.

Stay OSHA & Labor Law Compliant

Safety Data Sheets are only one part of workplace compliance. Most employers are also required to display current Federal and State Labor Law Posters where employees can easily review their workplace rights.

What Is a Safety Data Sheet (SDS)?

A Safety Data Sheet (SDS) is a standardized document that provides detailed information about a hazardous chemical.

An SDS helps employees understand:

  • Chemical hazards
  • Safe handling procedures
  • Proper storage
  • Personal protective equipment (PPE)
  • First aid procedures
  • Spill response
  • Firefighting information
  • Disposal considerations

OSHA requires chemical manufacturers and importers to prepare SDSs for hazardous chemicals.

OSHA's Standardized 16-Section SDS Format

Under OSHA's Hazard Communication Standard, SDSs follow a standardized 16-section format.

  • Manufacturer information
  • Emergency contact information
  • Recommended use

Section 2 – Hazard Identification

Includes:

  • Hazard classifications
  • Signal words
  • Hazard statements
  • Precautionary statements
  • GHS pictograms

Section 3 – Composition / Information on Ingredients

Lists:

  • Hazardous ingredients
  • Chemical names
  • Concentrations
  • CAS numbers (when applicable)

Employer Responsibilities

Employers should:

  • Maintain an SDS for every hazardous chemical in the workplace.
  • Ensure SDSs are readily accessible during each work shift.
  • Update SDS files when new versions become available.
  • Train employees on how to read and use SDSs.
  • Maintain an accurate hazardous chemical inventory.
  • Include SDS procedures in the written Hazard Communication Program.

Employees should never have difficulty accessing Safety Data Sheets.

Employee Training

Employees should know:

  • Where SDSs are located.
  • How to read each SDS section.
  • How to identify chemical hazards.
  • Required PPE.
  • Emergency response procedures.
  • Spill response procedures.
  • First aid information.

Training should occur before employees work with hazardous chemicals.

Electronic SDS Systems

Many employers now maintain SDS libraries electronically.

Electronic systems should:

  • Be easily accessible.
  • Be available during every work shift.
  • Allow employees immediate access during emergencies.
  • Include current SDS versions.

Employers should also have backup procedures if electronic systems become unavailable.

Common OSHA SDS Violations

Frequently cited violations include:

  • Missing Safety Data Sheets
  • Outdated SDS files
  • Employees unable to access SDSs
  • Missing employee training
  • Incomplete Hazard Communication Programs
  • Chemical inventory inconsistencies
  • Missing secondary container labels
  • Poor chemical storage practices

Routine audits help employers identify these issues before OSHA inspections.

Best Practices

Employers can improve SDS compliance by:

  • Reviewing SDS files annually.
  • Keeping electronic and backup copies available.
  • Updating chemical inventories regularly.
  • Removing obsolete SDSs when chemicals are no longer used.
  • Training new employees before chemical exposure.
  • Performing periodic Hazard Communication audits.
  • Posting chemical safety reminders in work areas.

A well-managed SDS program improves employee safety while supporting OSHA compliance.
