My Experience with On-Line Distance Education
• Developed Lab-XL project with EPA Region 1 and DC from 1996-2000
• Taught HAZWOPER (chemical safety for field students) with an on-line component from 2000 to 2011
• Participated in the 2004 OLCC On Lab Safety • Used Mediawiki platform for student assignments
and reports

LookingforStructureintheElectronicData
• How large is the PubChem chem safety information universe?
• How high quality is it (including consistency & provenance information)?
• How large is the Wikipedia chem safety information universe?
• How high quality is it?
How much overlap is there between the two?
Key safety information fields: - GHS class designation(s) and
signal word - NFPA diamond information
10,000 Chemboxes
Millions of chemicals; 3500 with GHS info
