Hazard Communication Standard
The Globally Harmonized System of Chemical Classification (GHS)
In March of 2012, the Occupational Safety and Health Administration (OSHA) updated the Hazard Communication Standard CFR29 1910.1200 (HazCom) to align with the Globally Harmonized System of Chemical Classification (GHS). Since then, chemical manufacturers, distributors, employers and consumers have seen changes in the way that chemical hazards are communicated on labels and safety documentation.
The intent of the new legislation was to make it easier for workers to understand chemical hazards, especially workers who may not speak or read English well, reduce confusion in the workplace, make safety training easier, and result in safer handling and use of chemicals. The new format provides workers with quicker and more efficient access to information on the labels and safety data sheets. The changes also save money for American businesses with productivity improvements projected because of fewer safety data sheet and label updates and simpler new hazard communication training. The new labeling system should also reduce trade barriers by coordinating with systems already in use in other countries.
What this means for employees at UAB
Since these major changes to labeling and safety information apply to all materials that have a chemical hazard, everyone employed by the University or the University Medical System will need to take the basic Hazard Communication training HS200. Many job classifications may not work directly with hazardous chemicals, but since everyday materials such as paints drain cleaners and disinfectants will be relabeled using the new system, everyone needs to know how to recognize and use the new labels and information sheets.
- Manufacturers must now classify hazardous chemicals according to standardized international criteria.
- The detailed chemical information sheets are now called Safety Data Sheets instead of Material Safety Data Sheets and the layout of the information is always organized the same way.
- Pictograms will provide visual clues of the chemical hazards.
- Signal words: Danger and Warning will be used to describe how dangerous the material is.
Labels are organized the same way with the following standard components.
• The Product Identifier or material name
• Supplier Identification to let users know who manufactured or distributed the material
• Precautionary Statements that describe how to protect yourself from the dangers of the material
• Pictograms to provide a visual clue to the hazards.
• Signal Words that describe the relative hazard, just like on the safety data sheet
• Hazard Statements that describe the characteristic that makes the material dangerous
• Supplemental Information that may give contact information for getting additional information or contacting the manufacturer.
Safety Data Sheets have 16 Required Elements all listed in the same order. In addition, the information in section 2 will include the same pictograms and warnings as the information on the label. Here are the required sections of the new safety data sheets.
Section 1, Identification
Section 2, Hazard(s) identification
Section 3, Composition/information on ingredients
Section 4, First-aid measures
Section 5, Fire-fighting measures
Section 6, Accidental release measures
Section 7, Handling and storage
Section 8, Exposure controls/personal protection
Section 9, Physical and chemical properties
Section 10, Stability and reactivity
Section 11, Toxicological information
Section 12, Ecological information
Section 13, Disposal considerations
Section 14, Transport information
Section 15, Regulatory information
Section 16, other information

Making Sense Out of Chemical Storage
The Department of Occupational Health and Safety is starting the implementation of a campus-wide chemical inventory system to track hazardous chemicals. The system utilizes bar codes and features a web-based interface. This will allow researchers, laboratory staff and other chemical users to track chemicals on-hand, will aid OH&S with regulatory agency reporting, and will provide emergency responders with accurate information on the chemical hazards present within an area should an incident occur.
We understand that some areas use large amounts of commercial products or may use chemicals that are mixtures that need to be inventoried. These items may not have a CAS# or they may have more than one CAS# associated with them. We have created UAB and OH&S numbers for these items to input into the CAS# field on the Chemical Inventory System. Should you find that the chemical/product you are looking for is not present on our list of created UAB and OH&S numbers please contact OH&S at 934-2487.
Most chemicals will need to be entered into the inventory, but except the following:
- Consumer products such as cleaning agents; contact OH&S regarding chlorine bleach. Large quantities need to be inventoried.
- Sugars and non-hazardous buffer salts
- Amino acids
- Materials of biological origin except for toxins
- Dilutions made by laboratory staff
- Culture media, agar and broth
- Latex paint
- Printer inks and toner
- Research samples
OH&S staff will be meeting with departmental staff to discuss the program's use and features. To make this transition easier, OH&S will perform the initial inventory in each laboratory. We are asking that unwanted and expired chemicals be disposed and any excessive clutter be removed before the inventory takes place to make the process as safe and efficient as possible. Here are some guidelines for lab staff:
- Discard all chemicals that are no longer useful to your research, expired (or more than 5 years old), or degraded – look for crystals, phase separation, container damage. Properly pack these chemicals and complete a Hazardous Waste Manifest to have them picked up.
- Ensure that any spills or other contamination are cleaned up properly – pay particular attention to cabinets and refrigerators.
- Check that chemicals in freezers are not frozen together or stuck to the sides or shelves.
- Ensure that materials to be inventoried are in their proper storage location.
- Ensure that chemicals have legible and appropriate labels – the ChemWatch system can be used to print a GHS compliant label if the original container label is damaged or inadequate. Structures and abbreviations of chemical names are not appropriate as the sole indicator of a chemical's identity.
- Place signs or communicate directly with the personnel who are conducting the inventory if there are sensitive or potentially hazardous procedures in progress.
- Ensure that there is a clean counter space for sorting and marking of chemical containers.
- Set aside a location for staging of containers that may need to be relabeled or packed as waste.
- Make sure aisles are clear and that there is good access to all chemical storage locations.
- Chemical containers will be barcoded and returned to their original location after being entered into the Chemical Management System.
- Containers that are damaged, unlabeled, or expired will not be entered and will be moved to the designated location for disposal.
- Chemicals in locations that show signs of gross leakage or contamination will not be entered and the materials will be marked for disposal as waste.
- Most chemicals in their original containers will be inventoried. Buffers, dilutions and cleaning products will not be included in the inventory.
- You will be given a supply of preprinted barcode labels to use for chemicals purchased in the future. When you need additional labels contact OH&S at 934-2487.
One of the most underestimated processes in labs is also one of the most critical, and that is managing an up-to-date chemical inventory system.
Once OH&S completes the initial chemical inventory, it is up to the individual laboratories to maintain it.
Features of the UAB Chemical Inventory System
- Search your chemical inventory by name, CAS number, barcode number
- Add or Edit the information for any of your chemicals in your inventory:
- There are many optional fields that you may include information about your chemical, storage location descriptions
- Have immediate access to Safety Data Sheets (SDS):
- We are working on this and will be available soon.
- New Chemicals entering the lab
It is the responsibility of the lab to enter each chemical coming to the lab into the database by utilizing a barcode system. Barcodes are provided by OH&S and the Chemical Inventory Instructions explains the simple and easy process of updating your inventory.
- Removing used/expired chemicals
When chemicals on your inventory expire, you must remove them first from the inventory before manifesting as hazardous waste. Similarly if the bottle is completely used up, remove the item from the inventory first and dispose the bottle by following OH&S guidelines.
- Redistributing/sharing chemicals with other labs or moving to another location
It makes perfect sense for labs to redistribute chemicals if a project ends or that particular chemical no longer needed (Funding agency regulations must be followed at all times when it comes to redistributing). Since a unique bar code specific to a location and PI adheres to every chemical container, it is very important not to move chemicals to another location without first deleting them from your inventory and adding to the inventory of the receiving lab. Barcodes make it easier to track inventory by taking away almost all manual input. Each chemical will be set up in the system one time. On the user end, when a chemical is going to another lab, users only have to follow instructions contained within Chemical Inventory Instruction manual.
Should your lab close or move for some reason, please do not leave any chemicals for the next person moving into the space. If you no longer want the chemicals in your chemical inventory it is required that you follow the procedure in the above paragraph, should another PI want them, or manifest the chemicals out as hazardous waste.
All hazardous chemicals with an NFPA rating of a 2 or above need to be included in the inventory.
General rule of thumb, if a chemical has any GHS pictogram or the diamond on the chemical has a 2 in any section, it should be added to your chemical inventory.
