MSDS sheets should be updated regularly to ensure they contain the most accurate and up-to-date information. In Canada, WHMIS requires that MSDS sheets be updated at least every three years. If new, significant information becomes available before the three-year period has elapsed, the supplier is required to update the product label and MSDS sheet.
5. Common Questions About MSDS Sheets
Here are some common questions about MSDS sheets:
| Question | Answer |
|---|---|
| What is the difference between an MSDS and an SDS? | MSDS (Material Safety Data Sheet) is the older term. SDS (Safety Data Sheet) is the newer, internationally standardized term used under the Globally Harmonized System (GHS). They both serve the same purpose: to provide information about hazardous chemicals. |
| Where can I find MSDS sheets? | You can find MSDS sheets on the manufacturer or supplier’s website, from your employer, or through online databases. |
| How often should MSDS sheets be updated? | In Canada, WHMIS requires that MSDS sheets be updated at least every three years. However, if new, significant information becomes available, the MSDS sheet should be updated immediately. |
| What should I do if I can’t find an MSDS sheet for a chemical? | Contact the manufacturer or supplier of the chemical and request an MSDS sheet. If you are unable to obtain an MSDS sheet, do not use the chemical and consult with a safety professional. |
| Do I need to read every section of an MSDS sheet? | Yes, it is important to read and understand all sections of the MSDS sheet to be fully informed about the potential hazards and safe handling practices for the chemical. However, some sections may be more relevant to your specific job tasks than others. |
| What should I do if I don’t understand something on an MSDS sheet? | Ask your supervisor, a safety professional, or the manufacturer or supplier of the chemical for clarification. It is important to fully understand the information on the MSDS sheet before working with the chemical. |
| Are MSDS sheets required for all chemicals? | MSDS sheets are required for all hazardous chemicals. Non-hazardous chemicals do not require MSDS sheets. |
| Can I use an MSDS sheet from another country? | While the information may be helpful, it’s best to use an MSDS sheet that complies with the regulations of your country or region. For example, in Canada, the MSDS sheet should comply with WHMIS requirements. |
| What is the “Regulatory Information” section on an MSDS sheet? | This section provides information on the regulations that apply to the chemical, such as safety, health, and environmental regulations. In Canada, this section should include the statement “This product has been classified in accordance with the hazard criteria of the CPR and the MSDS contains all of the information required by the CPR” if the product is controlled under WHMIS. |
| What are exposure limits on an MSDS? | Exposure limits, such as Permissible Exposure Limits (PELs) or Threshold Limit Values (TLVs), are legal or recommended limits on the amount of a chemical that a worker can be exposed to over a certain period of time. These limits are designed to protect workers from the harmful health effects of chemical exposure. |
6. The Globally Harmonized System (GHS) and SDS
The Globally Harmonized System (GHS) is an internationally recognized system for standardizing hazard communication. It aims to ensure that information on chemical hazards is consistent and easily understood across different countries.
6.1. GHS and MSDS Sheets
The GHS has replaced MSDS sheets with Safety Data Sheets (SDS). SDSs follow a standardized 16-section format, making it easier for users to find the information they need.
6.2. GHS Hazard Pictograms
The GHS uses hazard pictograms to visually represent the hazards associated with a chemical. These pictograms are standardized and easily recognizable, regardless of the language spoken.
6.3. Benefits of GHS
The GHS offers several benefits:
- Improved Hazard Communication: The GHS provides a standardized system for hazard communication, making it easier for users to understand the hazards associated with chemicals.
- Reduced Trade Barriers: The GHS reduces trade barriers by ensuring that information on chemical hazards is consistent across different countries.
- Enhanced Worker Safety: The GHS enhances worker safety by providing clear and consistent information on chemical hazards, allowing workers to take necessary precautions.
