Hi Stella - I note also that both reports to PubChem show the oxidizer pictogram. Interesting.  What manufacturer is it?

Today, I unboxed a new chemical and noticed that it did not have all the required GHS pictographs on it.. The substance was calcium nitrate ... no oxidizer symbol.

This is an interesting point. The PubChem Lab Chemical Safety Summary for calcium nitrate 
https://pubchem.ncbi.nlm.nih.gov/compound/24963#datasheet=LCSS&section=GHS-Classification
lets us know that there is significant disagreement within the European Chemicals Agency (ECHA). Only irritant is assigned by more than 60% of the notifications on this chemical:
- Aggregated GHS information provided by 718 companies from 25 notifications to the ECHA C&L Inventory. Each notification may be associated with multiple companies.
- Reported as not meeting GHS hazard criteria by 4 of 718 companies. For more detailed information, please visit ECHA C&L website
- Of the 24 notification(s) provided by 714 of 718 companies with hazard statement code(s):
- H271 (10.36%): May cause fire or explosion; strong Oxidizer [Danger Oxidizing liquids; Oxidizing solids]
- H272 (27.03%): May intensify fire; oxidizer [Danger Oxidizing liquids; Oxidizing solids]
- H302 (34.31%): Harmful if swallowed [Warning Acute toxicity, oral]
- H315 (62.61%): Causes skin irritation [Warning Skin corrosion/irritation]
- H318 (24.65%): Causes serious eye damage [Danger Serious eye damage/eye irritation]
- H319 (66.11%): Causes serious eye irritation [Warning Serious eye damage/eye irritation]

Information may vary between notifications depending on impurities, additives, and other factors. The percentage value in parenthesis indicates the notified classification ratio from companies that provide hazard codes. Only hazard codes with percentage values above 10% are shown.

Thanks for pointing this out.
