Material Safety Data Sheets (MSDS): An Overview

While regulations for Material Safety Data Sheet (MSDS) differ by location, their purpose remains universal: safeguarding individuals working with potentially hazardous chemicals. These readily available documents offer employees crucial information about the properties, hazards, and safe handling procedures of the chemicals they encounter. Understanding MSDSs empowers individuals to navigate their work environments and daily lives with confidence, knowing the key to handling chemicals safely is readily accessible.

What Does MSDS Stand For?

MSDS stands for Material Safety Data Sheet. It’s a paper with important details about things that might be unsafe in a workplace. Sometimes people call it SDS or PSDS too. No matter what letters they use, these papers are super important for keeping a place safe.

Manufacturers of dangerous chemicals make MSDSs. The owner or manager of the workplace keeps them. If needed, they can keep a list instead of actual sheets to protect sensitive information.

OSHA, or the Occupational Safety and Health Administration, says workplaces must have MSDSs. It tells people how to work safely with hazardous substances. It has information like what gear to wear, what to do if there’s a spill, how to help someone if they’re hurt, and how to store or throw away dangerous chemicals. MSDS also talks about what happens if you’re around it a lot and how it might affect your health.

What is the Purpose of MSDS?

The Material Safety Data Sheet (MSDS) gives important safety details about chemicals to people who use them. This includes workers who handle dangerous chemicals, those who store them, and emergency responders like firefighters and medical technicians. MSDS sheets are super important for following safety rules set by the United States OSHA Hazard Communication Standard. This rule says that anyone who might deal with or be around hazardous materials needs to have access to these safety sheets.

Importance of Material Safety Data Sheet

Having a Material Safety Data Sheet (MSDS) is super important in workplaces for many reasons. It’s like the first step in making sure everyone stays safe and healthy at work. When companies make products with chemicals, they have to include an MSDS with each one.

Workers have the right to know what they’re dealing with, so the MSDS must be filled out accurately. Employers must make sure they do this properly.

Companies that want to sell stuff in the European Union need to label their products correctly. The MSDS is usually split into different parts, sometimes up to 16 sections, each with specific details.

Some parts include:

• Information about the product, like who made it and emergency contact details.
• Details about any dangerous materials inside.
• Data about fire or explosion risks.
• Physical details, like when the material might catch fire or melt.
• Any harmful effects on health.
• Recommendations for how to use the material safely, including spill handling, disposal, and packaging.
• First aid info and emergency procedures, with details on symptoms from too much exposure.
• The name of the person responsible for making the product and the date it was made.

Who Uses Material Safety Data Sheets?

There isn’t just one answer to who should use MSDS. In simple terms, anyone who deals with or uses a product should be able to get the MSDS.

This includes:

• People who make things (Manufacturers)
• Those who provide the materials (Suppliers)
• People who bring in stuff from other countries (Importers)
• Those who move products around in the same country (Distributors)
• People who sell to regular customers (Retailers)

Let’s break it down with an example: Imagine you’re creating a new product using beeswax and soy wax. The folks who give you these materials (the suppliers) need the MSDS to handle them safely. If the suppliers directly sell to manufacturers like you, they also have to share the MSDS with you before sending the products.

Responsibilities Related to the MSDS

1. Suppliers

   • Product Information for Suppliers: If you’re supplying or selling controlled products for use at a workplace, make sure to create or get a Material Safety Data Sheet (MSDS) for each product.
   • Up-to-date MSDS: Make sure the MSDS for the controlled product has the latest information when you sell or import it. It should be prepared and dated within the last three years and be available in both official languages.
   • Provide SDS to Purchasers: Ensure that the buyer of the product has a copy of the latest SDS either at the time of purchase or before receiving the product.
   • Sharing Confidential Information: If there’s any information that’s considered confidential (like trade secrets), and therefore not disclosed, it must be provided to any doctor or nurse who needs it for medical reasons, like making a diagnosis or giving treatment.

2. Employer

   • Getting the Right Info: Employers need to make sure they get an updated safety sheet from the supplier the first time they receive a product that needs control in the workplace.
   • Checking Dates: They should check the date on the safety sheet to make sure it’s not older than 3 years from today’s date.
   • Keeping Safety Sheets Up to Date: Employers must keep safety sheets current. They should update them within 90 days if new safety information comes up, and they should check them at least every three years.
   • Making Safety Information Accessible: Employers have to make sure all workers who might be around the product can easily get a copy of the safety sheet. They also need to have it available for the occupational health committee. It’s okay to have the safety sheets on a computer, but employees must be able to access them easily, and they need training on how to use the computer system.
   • Employee Training: Employees who handle or are near controlled products need to be trained on what’s in the safety sheets. They need to understand the information and know how to safely use, store, handle, and get rid of the products, especially in emergencies.
   • Sharing Info with Medical Professionals: Employers should give doctors or nurses any secret safety info they ask for if it’s needed for medical help in an emergency.
   • Customizing Safety Sheets: Employers can make their safety sheets with extra information or change the layout as long as it still has all the important details that were in the original supplier safety sheet.

3. Worker

   After getting trained by the employer:

   • Follows safety rules and prevention steps as told by the employer.
   • Understand where safety sheets are kept and how to find important info about using them safely and first aid.

OSHA Rules for MSDS

Every Material Safety Data Sheet (MSDS) has to follow certain rules set by OSHA. These rules include putting these categories on every sheet:

1. Who Made It? – Manufacturer’s Name and How to Contact Them
2. What’s Inside? – Hazardous Ingredients and What They Are
3. What’s It Like? – Physical and Chemical Characteristics
4. Can It Catch Fire? – Data About Fire and Explosions
5. How Does It React? – Information on Reactivity
6. Is It Bad for You? – Health Hazard Data
7. How to Be Safe – Tips for Handling and Using It Safely
8. What Can You Do? – Control Measures to Stay Safe

Material Safety Data Sheet Content

When you get a safety data sheet from a supplier, it has to cover nine main areas and include about sixty pieces of information. It’s important to review the safety data sheet every three years to make sure it’s still accurate. Here are the main sections it needs to have:

1. Dangerous Ingredients

   This part tells you about any dangerous ingredients in the product.

   It includes:

   • The names and amounts of the risky ingredients
   • The LD50 and LC50, show how toxic the product is in the short term
   • The CAS number, which helps find more information about the product

2. How It’s Made

   This section tells you who made the safety data sheet and when. If it’s older than three years, it needs updating.

3. About the Product

   This part helps you identify the product and includes:

   • Its name as it appears on the label
   • Chemical name, family, and formula, including its weight
   • Product identifiers, and info about the manufacturer and supplier, including addresses and emergency phone numbers

4. Understanding Physical Data

   This part gives details about how a substance looks and acts in different situations:

   • What form it’s in, like if it’s a liquid
   • How it smells and looks
   • Specific details like how heavy it is, how fast it evaporates, and its boiling and freezing points
   • How much it can turn into vapor, which can affect the air around it
   • How much you need to smell it
   • Its acidity or alkalinity, which can tell if it’s harmful

5. Fire and Explosion Info

   This section talks about:

   • When the substance might catch fire or blow up, and what temperature or conditions cause that
   • Limits on how much of it in the air can cause a fire or explosion
   • What to use to put out a fire caused by it, like the right kind of fire extinguisher
   • Gear you need to protect yourself if there’s a fire
   • Some details about storing it safely, but you’ll find more about that in the reactivity data section

6. Reactivity Details

   Here, you learn about:

   • How stable the substance is and what might make it change, like light, heat, or water
   • How it should be stored based on how it reacts with other materials
   • What things you can’t mix with it or store near it
   • When you need to get rid of it before it gets really unstable

7. Toxicology Properties:

   This part tells us:

   • How dangerous it is if we’re exposed to something.
   • How the product gets into our body and what it does to our organs.
   • The short-term (right away) and long-term (over time) health effects of using the product.
   • The limits for how much of the harmful stuff can be in the air where people work. There are different limits:
   • TWA says how much on average for a regular workday.
   • STEL is the max for a short time, like 15 minutes.
   • C is the highest limit that can never be passed, not even for a moment.
   • If these limits are crossed, workers need special gear to protect themselves. The limits are shown in ppm for gases and vapors and as mg/m3 for dust, fumes, and mists.
   • Sometimes, you’ll see these limits as OEL, PEL, and TLV. This helps check if a worker’s health issues are because of the chemical.

8. Preventative Measures:

   This part gives us:

   • How to use, handle, and store the product safely.
   • What personal safety gear or devices are needed
   • Steps to clean up spills.
   • How to get rid of waste safely.

9. First Aid Measures

   This part talks about:

   • First aid to use if someone has problems from being exposed to the product.
   • The right steps to take for first aid.
   • Information to help plan for emergencies.

What is the Difference Between MSDS and SDS?

Imagine the MSDS as the chemical safety pamphlet of the past. It provided important info, but the format varied, like different versions of the same story told in different towns. The SDS is the updated, international handbook. It follows the GHS code, creating a universal format everyone can understand, like a single, global safety manual for chemicals. Both offer the same core message: “Handle this with care!” However, the SDS ensures clear, consistent communication across the world, regardless of language or industry.

Storing Material Safety Data Sheets (MSDS) In Your CMMS

To make sure everyone on your staff can easily find your MSDS (Material Safety Data Sheets), you can put them in your CMMS (Computerized Maintenance Management System). Each chemical you have can have its MSDS attached to it.

Check your local rules to know exactly how to store MSDS for your company. In the USA, OSHA says it’s okay to keep MSDS electronically as long as they’re easy to get to, but you still need to keep a physical copy too. You can learn more on the OSHA website.
