SDSs (Safety Data Sheets) were originally known as MSDS (Material Safety Data Sheets). However, since the adoption of the GHS (Globally Harmonized System of Classification and Labelling of Chemicals), MSDS has transitioned into SDS for standardized hazard communication.
The hazard communication standard requires that chemical manufacturers, distributors, or importers must provide SDSs for each hazardous chemical, to communicate hazardous information.
The SDS will include information including:
- Property of the chemical
- The physical, health, and environmental health hazards
- Protective measures
- And safety precautions for handling, storing, and transporting of the chemical
SDSs 16-Section Format
Each SDS is presented in a 16-section format and contains different information pertaining to the chemical.
Section 1: Identification
The first section on the SDS is used to identify what the chemical is and its recommended use(s). This section typically provides the suppliers contact information.
Section 2: Hazard Identification
This section identifies the hazards associated with the chemical and appropriate warning information for the hazards.
Section 3: Composition/Information on Ingredients
This section of the SDS lists the ingredients of the chemical, including impurities and stabilizing additives. It also provides details on substances, mixtures, and any chemicals for which a trade secret is claimed.
Section 4: First Aid Measures
Section 4 outlines the immediate care required by untrained responders for individuals exposed to the chemical. It provides essential first aid instructions for each route of exposure, including inhalation, skin and eye contact, and ingestion.
Additionally, this section highlights the most important symptoms and effects of exposure and offers guidance on the appropriate medical care to seek.
Section 5: Fire-Fighting Measures
This section provides:
- Recommendations for fighting a fire caused by the chemical
- Recommendations of suitable extinguishing equipment
- Information on non-appropriate extinguishing equipment for a particular situation
- And advice on specific hazards that may develop from the chemical during a fire
Section 6: Accidental Release Measures
Section 6 provides recommendations for responding to spills, leaks, or releases, including containment and cleanup procedures designed to minimize or prevent exposure to people, properties, and the environment. It also offers guidance on how to differentiate between responses for large and small spills, based on the volume of the spill and its potential impact on the hazard.
Section 7: Handling and Storage
This section provides guidance on safe handling practices and conditions for safe storage. Precautions for safe handing incompatible chemicals and general hygiene practices is also included under section 7.
Section 8: Exposure Control/Personal Protection
This part indicates the exposure limits, engineering controls, and personal protective measures. Special requirements for personal protective equipment may be included.
Section 9: Physical and Chemical Properties
Physical and chemical properties associated with the substance or mixture will be described in this section. Additional information provided include:
- Appearance
- Odor
- pH
- Melting and freezing point
- Flash point
- Flammability
- And other physical and chemical properties
Section 10: Stability and Reactivity
Section 10 is divided into three parts to outline the chemical’s reactivity hazards and stability information. These parts include reactivity, chemical stability, and other.
Section 11: Toxicological Information
This section identifies toxicological and health effects information or indicates that such data is not available. This part also provides the following information:
- Likely routes of exposure
- Description of delayed, immediate, or chronic effects from short-and-long term exposure
- Numerical measures of toxicity
- Description of symptoms
- And indication of whether or not the chemical is listed in the National Toxicology Program Report on Carcinogens
Section 12: Ecological Information
This section provides information to assess the potential environmental impact of the chemical in the event of a release.
Section 13: Disposal Considerations
This part will provide guidance on:
- Proper disposal practices
- Recycling or reclamation of the chemical or its container
- And safe handling practices
To help minimize exposure, this section will refer readers to section 8.
Section 14: Transport Information
This area will provide guidance on classification information for shipping and transporting of hazardous chemicals by rail, road, air, or sea.
Section 15: Regulatory Information
This section identifies the safety, health, and environmental regulations specific for the product that is not indicated anywhere else on the SDS. This may include any national and/or regional regulatory information.
Section 16: Other Information
Section 16 specifies the date the SDS was originally prepared or last revised. It may also include any additional information the manufacturer deems necessary.
Employer Responsibilities
Employers must ensure SDSs are readily accessible to employees for all hazardous chemicals in the workplace. SDSs may be stored in a binder or on computers, if employees have immediate access to the information without leaving their work area. Additionally, a backup system should be in place to ensure quick access to the SDS in the event of a power outage or other emergency.
The employer may designate an employee who is responsible for obtaining and maintaining the SDS. If the designated employee or the employer does not have an SDS, contact the manufacturer to obtain one.
Conclusion
Safety Data Sheets (SDS) are essential tools for ensuring workplace safety and proper handling of chemicals. By providing critical information on potential hazards, exposure routes, and necessary precautions, SDSs help protect employees, the environment, and the community. Familiarizing yourself with these documents is key to promoting a safe and informed environment, whether you’re working with chemicals directly or managing workplace safety protocols.
