Diamond Hazard Value Description
1
1 0
Health   1 Exposure would cause irritation with only minor residual injury (e.g. acetone, sodium bromate, potassium chloride)
Flammability   1 Materials that require considerable preheating, under all ambient temperature conditions, before ignition and combustion can occur. Includes some finely divided suspended solids that do not require heating before ignition can occur. Flash point at or above 93.3 °C (200 °F). (e.g. mineral oil, ammonia)
Instability   0 Normally stable, even under fire exposure conditions, and is not reactive with water (e.g. helium,N2)
