Health Hazard
Excerpt from NIOSH Pocket Guide for Tin(II) oxide (as Sn):
Exposure Routes: Inhalation, skin and/or eye contact
Symptoms: Stannosis (benign pneumoconiosis): dyspnea (breathing difficulty), decreased pulmonary function
Target Organs: Respiratory system (NIOSH, 2024)
:Exposure Routes: Inhalation, skin and/or eye contact
Symptoms: Stannosis (benign pneumoconiosis): dyspnea (breathing difficulty), decreased pulmonary function
Target Organs: Respiratory system (NIOSH, 2024)
Reactivity Profile
TIN(II) OXIDE is a reducing agent. Unstable in air due to slow oxidation to tin(IV) oxide. At 300°C this oxidation proceeds incandescently. Incompatible with strong oxidizing agents. Reacts with acids and with strong bases.
Belongs to the Following Reactive Group(s)
Potentially Incompatible Absorbents
No information available.

First Aid
Excerpt from NIOSH Pocket Guide for Tin(II) oxide (as Sn):
Eye: IRRIGATE IMMEDIATELY - If this chemical contacts the eyes, immediately wash (irrigate) the eyes with large amounts of water, occasionally lifting the lower and upper lids. Get medical attention immediately.
Breathing: FRESH AIR - If a person breathes large amounts of this chemical, move the exposed person to fresh air at once. Other measures are usually unnecessary. (NIOSH, 2024)

Physical Properties

The
Physical Property fields
include properties such as vapor pressure and
boiling point, as well as explosive limits and
toxic exposure thresholds
The information in CAMEO Chemicals comes from a variety of
data sources.
Note: For Vapor Density and Specific Gravity, comparing the value to 1.0 can tell you if the chemical will likely sink/rise in air or sink/float in fresh water (respectively). Short phrases have been added to those values below as an aid. However, make sure to also consider the circumstances of a release. The Vapor Density comparisons are only valid when the gas escaping is at the same temperature as the surrounding air itself. If the chemical is escaping from a container where it was pressurized or refrigerated, it may first escape and behave as a heavy gas and sink in the air (even if it has a Vapor Density value less than 1). Also, the Specific Gravity comparisons are for fresh water (density 1.0 g/mL). If your spill is in salt water (density about 1.027 g/mL), you need to adjust the point of comparison. There are some chemicals that will sink in fresh water and float in salt water.
