Hazard Communication (HazCom)

The OSHA Hazard Communication Standard is designed to protect employees from hazardous chemicals used or stored in the work setting. Also referred to as Right To Know, it requires that training and information be provided to any employees who have the potential of being exposed to a hazardous chemical "under normal condition of use or in a forseeable emergency."

HazCom training requires the presence of hazardous chemicals be communicated to employees in a variety of ways, including:

  • The hazardous chemical inventory
  • Material Safety Data Sheets (MSDS) / Safety Data Sheets (SDS)
  • Labels, tags or signs
  • The written hazard communication program

OSHA Hazard Communication Standard aligns with the Globally Harmonized System of Chemical Classification and Labeling (GHS). There are requirements for:

HazCom Compliance Checklist

To be compliant, an employer must:

  • Train employees on the hazardous chemicals in the workplace
  • Instruct workers on how to recognize exposure to hazardous chemicals

  • Explain to employees how to access SDSs
