No specific hazards are encountered under normal product use.
Step to be taken in case of spill:
Small spills may be flushed to the sewer. Large spills could be collected by shovelling into appropriate waste collection containers. Clean-up by flushing with water if desired.
No specific hazards are encountered under normal product storage.
Change in physical state
Organic pigments, in general, are not expected to be toxic to fish because of their negligible water solubility thus they are not readily biodegradable.

Properties and Recommended Uses : P.O.13, also known as pyrazolone orange, comes in semitransparent types with specific surface areas between about 35 and 50 m2/g. It is coloristically very similar to P.O.34, but generally somewhat yellower
* Inks : PO – 13 gives Yellowish Orange Hue. Its Ink printing application includes Offset and Flexo printing inks. Also applicable for Solvent & Water Gravure.
In Polyamide & NC / Vinyl applications. it provides fairly good solvent fastness. However its Light fastness is moderate. Used due to its competitive price.
* Polymers : PVC: Considering its tendency to migrate, incorporation into plasticized PVC is not recommended. The pigment blooms over a large concentration range and bleeds
considerably. Even at low concentrations ca. PO-13 is not suited for use in rigid PVC.
* Polyolefins : Application of P.O.13 in polyolefins is limited – It is recommended for use at temperatures up to 200°C only. Even Polystyrene and other Plastic materials are to be processed below 200°C. In LDPE, there is some danger of blooming.
* Rubber : PO.13 can be used in the rubber industry. It is fast to vulcanization and bleeding in natural rubber.
* Paints : P.O.13 shows less stability in paints compared to P.O.34 of similar particle size.
This includes both fastness to over painting in baking enamels and light fastness in air drying paints. The volume of trade sales for this purpose is accordingly limited
* Others ; The graphics industry uses P.O.13 to an appreciable extent for packaging printing inks though its fastness to light is average.
As the stability of pigmented prints of PO-13 towards to a number of organic solvents is excellent used in packaging of paraffin based products, butter, and soap. They withstand heat very well and are stable up to 200°C ard also used for metal deco printing, provided its light fastness suits the purpose.
