ChemDB Description

ChemDB is a little Django app in Python for managing our lab's list of chemicals. It also generates door warnings and inventories for compliance with our safety requirements.Installing by handChemdb is available as a Git repository: git clone git://tremily.us/chemdb.gitSee the homepage for details. To install the checkout, run the standard: python setup.py installUsageSetupIf you don't have a Django project and you just want to run chemdb as a stand-alone service, you can use the example project written up in example. Set up the project (once): python example/manage.py syncdbSee the Django documentation for more details.You may also want to load some example data, to make your initial browsing more interesting: python example/manage.py loaddata example_dataRunningRun the app on your local host (as many times as you like): python example/manage.py runserverYou may need to add the current directory to PYTHONPATH so python can find the chemdb package. If you're running bash, that will look like: PYTHONPATH=".:$PYTHONPATH" python example/manage.py runserverHackingThis project was largely build following the Django tutorial. That's a good place to start if you're new to Django.Other resourcesYou can search CAS Registry numbers at NIST. This is useful for decoding MSDS information.NFPA fire diamondThese are the meanings of the various NFPA warnings:- Blue: Health Hazard0. Hazard no greater than ordinary material1. May cause irritation; minimal residual injury2. Intense or prolonged exposure may cause incapacitation; Residual injury may occur if not treated3. Exposure could cause serious injury even if treated4. Exposure may cause death- Red: Fire Hazard0. Will not burn1. Must be preheated for ignition; flashpoint above 200°F (93°C)2. Must be moderately heated for ignition, flashpoint above 100°F (38°C)3. Ignition may occur under most ambient conditions, Flashpoint below 100°F (38°C)4. Extremely flammable and will readily disperse through air under standard conditions, flashpoint below 73°F (23°C)- Reactivity hazards:1. Stable2. May become unstable at elevated temperatures and pressures. May be mildly water reactive3. Unstable; may undergo violent decomposition, but will not detonate. May form explosive mixtures with water4. Detonates with strong ignition source5. Readily detonates- Special Hazards have the following codes:- OX strong oxidizer- W̶ water reactive- SA simple asphyxiants (The only gases for which this symbol is permitted are nitrogen, helium, neon, argon, krypton, and xenon.)Product's homepage
