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 Magnesium sulfate, and where each one comes from
10 measured values for 4 properties, read from 2 public databases. On 2 properties the records differ. Each reading is shown with its own record. Follow any record to read the value at its source.
Melting point
2 records, 1124 to 1127 °C
Fixes the physical state at handling temperature, which the label and the transport class depend on.
- Decomposes @ 1124 °C
- Hazardous Substances Data Bank (HSDB)
Density
2 records differ
Needed to convert between mass and volume on the label, in transport papers and in a spill estimate.
- 2.66 g/cu cm
- Hazardous Substances Data Bank (HSDB)
Solubility
5 records, each a different case
Determines spill behaviour, the right extinguishing media and the correct first-aid rinse.
- SOL IN 2 PARTS H2O AT 20 °C /TRIHYDRATE/

Odour
1 record
Odour is a warning property only. Many substances are hazardous well below the concentration you can smell.
These are the public records read for Magnesium sulfate, 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.
