INCIDENT at UNC Chapel Hill Student Hurt in Explosion at UNC Lab Chapel Hill, NC Flying glass from a laboratory explosion cut a graduate student in a UNC Chemistry building on Wednesday
INCIDENT AT NC STATE
Karen Wetterhahn 1949-1997 Wetterhahn knew that dimethylmercury was highly toxic and she took reasonable precautions; she wore safety glasses and latex gloves, and manipulated the chemical in a fume cupboard Less than a year later, she was dead. Dimethylmercury penetrated the glove and started entering her skin within 15 seconds. Today researchers wear highly resistant laminated gloves underneath a pair of long-cuffed neoprene (or other heavy duty) gloves to handle dimethylmercury.

Hazard Communication Your right to know about the chemicals that you work with in your job.
Four Key Parts to Hazard Communication Labels MSDS Training Written Plan
Routes for Chemical Exposure Inhalation Ingestion Absorption Injection
Labels Identity Hazard Warning Name & Address of Manufacturer If you notice a label is missing, torn, or unreadable, contact your supervisor
Material Safety Data Sheets Product Identification Composition Hazard Identification First Aid Fire-fighting measures Accidental-Release measures Exposure control Personal Protection Physical and Chemical properties Stability and reactivity Toxicological info Ecological info Disposal Transport Regulatory Info

A Question... Are Chemical, Biological, and Radiological Hazards the only Hazards of a Lab Environment?
Hazard Signs
Subject Specific Training Radioactive Materials and Equipment Bloodborne Pathogens Laser Safety Respirator Use Hearing Conservation Other
ELECTRICAL / MECHANICAL Know the equipment and energy sources that you will be using. Use guarded equipment avoid pinch pts. Use ground fault protection Use double insulated or 3-wire power tools Lockout Tagout electrical safety Obtain training on the equipment that you will be working with.
Electrical Hazards Control of hazardous energy NEVER remove some else s lock and tag from any machine, equipment or device NEVER try to energize or start any machine, equipment, or device while it is locked or tagged out. You must attend NCSU Lockout Tagout training courses before you apply lockout tagout.
Personal Protective Equipment Employees must know: When/what type PPE is necessary How to properly wear Limitations Maintenance
Personal Protective Equipment Employers must conduct a hazard assessment to determine the PPE needed to conduct each task safely Hazard assessments conducted for the laboratory are maintained with the safety plan Tasks completed that are not covered by the safety plan must also be assessed to determine if and what PPE is needed.
