There is no difference between an MSDS and an SDS, as both are generic terms for safety data sheets. A GHS compliant safety data sheet is an SDS but not an MSDS. An SDS can be an MSDS, but an MSDS is not an SDS. And calling a document an SDS does not make it GHS compliant.
GHS uses three hazard classes: Health Hazards, Physical Hazards and Environmental Hazards. These aren’t required by OSHA. Health hazards present dangers to human health (i.e. breathing or vision) while physical hazards cause damage to the body (like skin corrosion).
A common way to classify hazards is by category:
Workplace labels are created by the users of hazardous products being used in an area other than a laboratory. These labels are applied to the container of a hazardous product that was: created in the workplace, received without a supplier label or. transferred into a container that had no labelling.
OSHA requires that labels on incoming containers of hazardous materials must not be removed or defaced until the container is empty and rinsed. No product or chemical shall be accepted without an adequate identifying label. Original containers should be labeled with the date received and the date opened.
The HCS requires chemical manufacturers, importers, or distributors to ensure that each container of hazardous chemicals leaving the workplace is labeled, tagged or marked with the following information: product identifier; signal word; hazard statement(s); precautionary 1 Page 2 2 statement(s); and pictogram(s); and …
You must use a workplace label on the container. There are two special cases when a workplace label is not necessary. When a controlled material is poured into a container and it is going to be used immediately, no label is required.
If you identify containers where the labels are missing or defaced, you must immediately replace them. Employers should consider the benefits of a chemical management software platform that enables fast, easy printing of workplace labels that replicate the shipped label for most of your containers.
If you find a container without a label or with a torn or illegible label, report it to your supervisor immediately. Don’t attempt to handle a chemical without a label until you know what it is.
A hazardous chemical is correctly labelled if it is packed in a container that has a label written in English that includes: The product identifier. Any information about the hazards, first aid and emergency procedures relevant to the chemical, which are not included in the hazard statement or precautionary statement.
Dangerous goods labels
What are the 9 classes of Dangerous Goods?
Class 2 dangerous goods are gases. It covers compressed gases, liquefied gases, dissolved gases, refrigerated liquefied gases, mixtures of gases and aerosol dispensers/articles containing gas.
|UN Class||Dangerous Goods||Classification|
|Non-flammable, non-toxic gas|
|3||Flammable liquid||Flammable liquid|
The category tells you about how hazardous the product is (that is, the severity of hazard). Category 1 is always the greatest level of hazard (that is, it is the most hazardous within that class). If Category 1 is further divided, Category 1A within the same hazard class is a greater hazard than category 1B.
Class 1 dangerous goods are explosive substances and articles. There are 6 sub-divisions: Division 1.1: Substances and articles which have a mass explosion hazard. Division 1.2: Substances and articles which have a projection hazard but not a mass explosion hazard.
Class 8 dangerous goods are corrosive substances. There is no sub-division. Corrosive substances may cause severe damage when in contact with living tissue such as skin or damage or destroy surrounding materials in case of leakage.
