Study Notes
GHS Overview
- Various chemical classification and labeling systems do not conflict.
- GHS is a flexible standard; countries can adopt it in different ways.
Benefits of GHS
- Enhances global competitiveness for companies.
- Improves worker safety.
Standardization Areas
- GHS standardizes classification of hazardous chemicals.
- It also standardizes methods for communicating chemical hazards.
Classification and Categories
- The United Nations developed GHS for clear handling instructions of hazardous chemicals.
- Three main hazard categories: Physical hazards, Health hazards, and Environmental hazards.
- Chemicals are classified based on their hazardous properties.
Specific Hazards
- Pyrophoric liquids classified as Physical hazards.
- Acute Aquatic Toxicity classified as Environmental hazards.
Hazard Communication
- Classification is the initial step in hazard communication.
- GHS labels include standardized components: Symbols/Pictograms, Signal Words, and Hazard Statements.
Labeling Components
- Pictograms are white diamonds with red borders.
- Pictograms for workplace labels differ from those for transport of hazardous materials.
- "Danger" signals more severe hazards than "Warning."
- Hazard statements describe nature and degree of hazards.
GHS Label Elements
- Important GHS label elements include: Precautionary Statements, Product Identifier, Supplier Identification, and Supplemental Information.
- Alternative hazard information display is not permitted under GHS.
Secondary Container Labeling
- Preferred labeling method for secondary containers at PennState University is HMIS.
HMIS and NFPA Labels
- The blue color indicates health hazards on HMIS/NFPA labels.
- Numbers represent hazards; lower numbers indicate less risk, with 0 being the least and 4 the most urgent.
Safety Data Sheet (SDS) Details
- Safety Data Sheets provide comprehensive hazard information beyond container labels.
- SDS format must be consistent; sections cannot vary in order.
Regulatory Information
- Regulatory Information section of the SDS details relevant safety, health, and environmental regulations.
Required SDS Sections
- Required SDS sections include: First Aid Measures, Firefighting Measures, Handling and Storage, Accidental Release Measures, and Ecological Information.
- Physical and Chemical Properties section includes information about a chemical's odor threshold, evaporation rate, and flash point.
Exposure Controls
- Engineering controls include exhaust ventilation and isolation rooms to mitigate chemical exposure.
- Personal Protective Equipment (PPE) excludes local ventilation as it is not considered protective gear.
