State the hazard warning label that should be shown on a jar of oxygen.
You do not state the physical state of the oxygen.
If it is a gas jar of oxygen then this site might help. It is a good site for MSD information.

To determine the hazard warning label that should be shown on a jar of oxygen, we need to consult official safety guidelines and regulations. In this case, we can refer to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS).
Step 1: Go to a reliable source
First, we need to access the GHS guidelines. The official website of the United Nations is a reputable source for reliable and up-to-date information. You can visit their website at https://www.unece.org/trans/danger/publi/ghs/ghs_welcome_e.html.
Step 2: Search for oxygen hazards
Once on the website, navigate to the GHS classification section. Search for "oxygen" or "compressed gases" to find the corresponding hazard information.
Step 3: Identify the hazard category
Look for the specific hazards associated with oxygen. Oxygen itself is not generally considered toxic or corrosive; however, it is highly reactive and can support combustion, thereby increasing the risk of fire or explosion. This information will help us determine the hazard category.
Step 4: Determine the hazard label
Based on the hazards associated with oxygen, you should look for the appropriate pictogram and hazard statement according to the GHS guidelines. The GHS system uses standardized symbols or pictograms to convey hazards visually, accompanied by hazard statements for further clarification.
Please note that I, as an AI, do not have direct access to the latest GHS guidelines. It is essential to verify and cross-reference the information found on the official United Nations website or consult relevant handbooks or safety regulations in your jurisdiction to ensure accurate and up-to-date hazard labels for a jar of oxygen.
