Master Safety Data Sheet

Definition:

MSDS stands for material safety data sheet. MSDS is a document that provides in-depth information regarding any chemical or product. This MSDS is intended to inform every end user of the chemical and others about the potential hazards of the material and the information about how to handle it safely.

Introduction: 

A Material Safety Data Sheet (MSDS) is also called a Safety Data Sheet (SDS). It is an informative set of documents provided by the manufacturer or supplier to the end user. MSDS has everything in it for safety purposes. MSDS gives the information on the physical and chemical properties of the product. It contains information on flash points, toxicity, procedures to handle spills and leaks. It also contains information on first aid in case of an emergency. The Material Safety Data Sheet (MSDS) is a reference document that is used to understand how to handle, store chemicals in the workplace. Worker handling such kind of hazardous chemicals should always be aware of how to use the MSDS. Knowledge of the MSDS helps workers to improve safety at the workplace. This blog will explain in short the basics of MSDS, its importance in the workplace and how it is crucial to be safe and compliant.

The History:

In 1970 Occupational Safety and Health Administration was established to ensure the safety and health of workers. It is compulsory to identify and disclose the hazardous nature of the chemicals. The hazardous nature of chemicals should be disclosed as information on the containers in which it is stored. This information should be placed on the containers in the form of labels, and shipments should be done along with MSDS. Further, in 1994 HCS policy was revised, and a must-have 16-section informative format was introduced, which has different critical information compiled in one place. In 2002 United Nations accepted the Globally Harmonised system of classification and labelling of chemicals.

This HCS policy is then accepted worldwide for the Hazard classification, and it has become a standard practice and harmonised. During 2012, OSHA merged with GHS and revised HCS to be in line with MSDS, and now MSDS is renamed as Safety Data Sheet (SDS). This MSDS or SDS has 16 sections, and information regarding all sections is made compulsory. In some countries, it is covered under law, and the unavailability of MSDS for any hazardous chemical is termed a serious violation of safety and compliance and may also face legal actions.

The Objective: The main objectives of the MSDS are:

1. It helps to identify Hazards.
2. Protecting the workplace and workers.
3. It is useful in emergency situations to respond.
4. Environmental safety.

The MSDS document is provided with details of chemical properties, what type of hazards are associated with handling and how it can be handled safely and stored. Information provided in MSDS is used to protect the workplace as well as workers from hazards of handling by providing proper personal protective equipment. In case of emergency situations (i.e. Fire or spillage), the information provided on the MSDS is useful to control the situation. By following the instructions for handling, storage, transfer, use and disposal, these kinds of emergencies can be avoided. The information on the MSDS is also useful during safe and environmentally friendly disposal of chemicals. MSDS can be referred to as a powerful tool for training employees about the potential hazards of chemicals and safe handling of the same. What to do in case of an emergency, and the measures to be taken if someone is exposed to it. This MSDS can be accessed from the manufacturer or supplier directly or can be downloaded from their websites. Few online databases collect and store information regarding chemicals with their MSDS. These online data sources can be used to access the MSDS. Every workplace must have a copy of the MSDS for easy access to the end user.

Sections or Content of MSDS:

The MSDS contains different sections that provide detailed and essential information about a chemical or product, and it may contain the following common information in MSDS.

1. Identification: This section contains information related to the product name, its manufacturer’s details and emergency contact information.
2. Hazard Identification: This section of MSDS has the classification of chemical, whether flammable, highly flammable, toxic, or Corrosive. Certain words like Danger, Warning statements. This classification and warning statements help to prevent potential accidents.
3. Information regarding composition: It discloses chemical identification of the substance, its common name CAS number.
4. First aid Measures: This section has the information related to first aid in case of substance is exposed to the worker through skin, eye, or inhalation.
5. Accidental Release Measures:  In this section end user can find the information regarding the Steps to be taken in case of spillage or leakage. This section helps with procedures of containment and cleanup.
6. Personal Protection: In this section of the MSDS, information about the Exposure limits (if applicable) is available. Also, this section recommends the use of personal protective equipment (PPE) and guidelines for its safe use.
7. Handling and Storage: Instructions on how to handle the substance safely (e.g. Ventilation, precautions) and storage guidelines (e.g. Temperature, incompatibilities) are given in this section.
8. Fire-Fighting Measures: This section contains the information on Suitable fire extinguishing media, potential fire hazards, and protective equipment for firefighters.
9. Physical and Chemical Properties: Data on the physical characteristics of the substance (e.g. appearance, odour, pH, melting point, boiling point, flash point). This section helps the end user during handling.
10. Toxicological Information: One section of MSDS provides Health effects information, which includes acute and chronic toxicity-related data or limits, routes of exposure, symptoms, and potential long-term effects if exposed to the chemical.
11. Transport Information: Directions of how Shipping needs to be done and its classification (e.g., UN number, hazard class, packaging group) and any special transport requirements, if required, are mentioned in this section.
12. Ecological Information: This part of MSDS contains information regarding the impact of the chemical on the environment when disposed of and the effect on aquatic animals and other environmental factors.
13. Regulatory Information: It contains relevant safety, health and environmental regulatory authorities’ laws applicable to the chemicals.
14. Other Information: This section indicates the revision history of the MSDS, if applicable, References referred for the preparation of the MSDS, and any other important general information.
15. Stability and Reactivity: Information about the stability of chemicals is mentioned in this section.
16. Disposal: Recommendations for the safe, eco-friendly and easy disposal of the chemical and recycling of its containers are explained in this section.

Some warning signs:

Conclusion:

To conclude, MSDS or SDS is a fundamental requirement of safety. This document provides basic, critical information about the physical and chemical properties of chemicals. Their safe handling procedures with precautions and potential risks during handling and use. It can be used to train employees; it helps workers and the workplace to be ready for any emergency situations. The use of MSDS also helps to save the environment. The use of MSDS improves safety and regulatory compliance.
