4 Risk Management

5 Information Management Ascertain relevant scope of information Enable efficient access to sources Support critical evaluation of sources and content Support incorporation into knowledge base Support effective use for specific purpose Ascertain economic, legal, ethical and social issues surrounding access and use of information

8 Caution! Dangerous Things! “Although we have encountered no problems in handling Cu-azido during this work, it should be treated with great caution owing to their potential explosive nature. Thus, it should only be handled in small amounts.” doi: /b702988h “Whilst no problems were encountered in the course of this work, perchlorate mixtures are potentially explosive and should therefore be handled with appropriate care.” doi: /b304841a “Thallium compounds are highly toxic; they should therefore be handled with extreme caution and all operations must be carried out in an efficient fume hood.” doi: /b102192n “we have not seen deflagration or detonation of any unconfined samples in the ignition experiments, some salts with high-oxygen and high-nitrogen content are known to be explosives, so appropriate precautions are advisable with new compounds” doi: /b602086k “Metal azide complexes are potentially explosive. Only a small amount of material should be prepared and should be handled with caution” doi: /b106314f “perchlorate salts of metal complexes are potentially explosive” doi: /b005671p “Special caution was taken in the handling of fluoranthene and in the preparation of the MIPs.” doi: /b502706c “anhydrous HF is an extremely corrosive and low boiling gas (19.5 °C) and should be handled in a well ventilated hood with protective gloves, face mask and clothing.” doi: /b206168f

9 A ‘Simple’ Taxonomy… Dangerous chemicals: perchlorates, thallium compounds, polonium, azides … which have the disposition to take part in… Dangerous processes: explosion, decarbonylation … under certain experimental conditions… … and these processes can be prevented (blocking the dispositions) or mitigated by…

10 Safety Measures Fume hoods mitigate carbon monoxide emission. Protective clothing prevents burning. Greener solvents improve waste handling. So… how do we model all this?
