PurposeIn order to ensure chemical safety in the workplace, information about the identities and hazards of the chemicals must be available and understandable to workers. OSHA's Hazard Communication Standard requires the development and dissemination of such information.

The Standard applies to Chemical Manufacturers Employers Employees

Chemical ManufacturersMust determine the physical and health
hazards of the products they make and provide that information to users.

Employers - MSUMust determine which workplace
materials are hazardous and provide employees with the information, training, and equipment they need to protect themselves and others.

EmployeesMust use their Right-to-Know knowledge
to stay safe and healthy on the job.

Why learn about chemicals?Chemicals have many valuable uses
and are used often. But many chemicals also have hazards
that can present risks to health and safety when they’re used on the job.

Health Hazards Acute Health Problems
symptoms show up immediately after exposure Chronic Health Problems
problems develop gradually from prolonged or repeated exposure

Physical Hazards Sudden release of pressure (explosion) Flammable (catches fire easily) Reactive (unstable chemicals)

What is GHS? The Globally Harmonized System (GHS)
is an international approach to chemical labels and safety data sheets (SDS).
OSHA’s Hazard Communication standard has adopted the GHS to improve safety and health of workers through more effective communications on chemical hazards.

Labeling Every container of hazardous chemicals is
labeled by the manufacturer. Labels make it easy to find at a glance the
chemical’s possible hazards and basic steps to take to protect yourself against those risks.

Safety Data Sheets (SDS) SDS are multi-page documents that
contain more detailed information about a chemical than the container label.
The revised HazCom standard requires that the information on the SDS is presented using consistent headings in a specific order.

Conclusion Workers have the right to know and
understand the hazardous chemicals they use and how to work with them safely.
Always read the chemical label and make sure you understand the information before working with a chemical in the workplace.
For more information, refer to the Safety Data Sheet.
