To determine the primary hazard associated with the image, one would need to know what the image depicts. However, since I don't have access to images or context, I can provide guidance based on common hazards.
If the image is related to:
- Flammable materials: The hazard would be "They can cause fires and explosions if improperly stored."
- Dust-generating materials: The hazard would be "They can generate large amounts of dust, posing inhalation risks."
- Corrosive substances: The hazard would be "They can cause severe burns to skin and damage to eyes."
- Certain chemicals: The hazard would be "They can release toxic fumes when mixed with water."
Please choose the response that best aligns with the content of the image you are referring to.
