Topic 3Safety Issues
Chapters 12 - 13
Information Sources
Where do you find information about the hazards of specific materials?
Hazard Labeling Systems
• National Fire Protection Association (NFPA) 704 Standard
• National Paints and Coating Association Hazardous Materials Information Systems (NPCA HMIS)
• Uniform Fire Code (UFC)
• American National Standards Institute (ANSI) Standard Z129.1
NFPA Examples

Safety Issues: Monitoring
Chapter 5
Exposure
• Routes
• Types
Monitoring Methods
• Area & perimeter monitoring
• Personal monitoring
What about using odor for detecting exposure?
What do we have to consider when sampling?
Medical Surveillance
Exposure Limits
• OSHA: TWA PELs or TLVs– EL or STEL– C– P– AL
• EPA: NCELs and AEGLs• NIOSH: RELs and IDLHs• AIHA: WEELs and ERPGs
Practice Problems
How can we limit exposures (i.e., protect workers)?
Safety Issues: Engineered Controls
Storage
What are the issues?
Common Storage Deficiencies
17Inadequate handling of empty drums
18Storm drains in liquid storage & transfer areas
18Inadequate handling of PCB materials
18No or inadequate haz waste contingency plan
24Incomplete wastewater analysis
34No or inadequate SPCC plan
40Inadequate training program
44Improper labeling
48No or inadequate inspection program
65No tank integrity testing
68Inadequate containment/drum/tank storage areas
