Not found in the public records searched: odor, boiling point, flash point, Log Pow (log Kow), vapor density, lower explosive limit, upper explosive limit, auto-ignition temperature, viscosity and pH. Enter these from your supplier's safety data sheet or your own test report before the draft is issued.
Occupational exposure limits for Iron oxide
The airborne limits on public record in the United States. These are transcribed from the tables named in each row, not derived. The full draft puts them in Section 8 with the control and PPE guidance.
OSHA PEL — TWA (8 h)
10 mg/m³

NIOSH REL — TWA (up to 10 h)

A value with no row here was assembled from more than one record, so no single record is credited for it. The draft you buy carries this table as an appendix covering all 16 sections.

Sections 1.3 and 1.4 are withheld here because the supplier and emergency contact blocks carry your own company details in the draft you buy. Every draft needs review by a competent person before it is issued.
Measured values for Iron oxide, and where each one comes from
12 measured values for 4 properties, read from 3 public databases. On 3 properties the records differ. Each reading is shown with its own record. Follow any record to read the value at its source.
Melting point
4 records, 1462 to 1565 °C
Fixes the physical state at handling temperature, which the label and the transport class depend on.
- 2664 °F
- NIOSH Pocket Guide
- 2849 °F
- NIOSH Pocket Guide
Vapour pressure
3 records differ
The higher it is, the faster the substance evaporates into the workplace air at room temperature.
- 0 mm Hg (approximate)
- Hazardous Substances Data Bank (HSDB)
- 0 mmHg (approx)
- NIOSH Pocket Guide
- 0 mmHg (approx)
- OSHA Occupational Chemical Database
Density
3 records differ
Needed to convert between mass and volume on the label, in transport papers and in a spill estimate.
- 5.25 g/cu cm
- Hazardous Substances Data Bank (HSDB)
Solubility
2 records, each a different case
Determines spill behaviour, the right extinguishing media and the correct first-aid rinse.
- Soluble in acids; insoluble in water, alcohol, ether
- Hazardous Substances Data Bank (HSDB)
- Insoluble
- NIOSH Pocket Guide
These are the public records read for Iron oxide, published here unchanged. Where two records disagree, the draft you buy states the value and names the record behind it, so a reviewer can see what was chosen. Every draft needs review by a competent person before it is issued.
