GPS/JIPS Safety Summary
1. SUBSTANCE NAME
Propylene (CAS No.: 115-07-1)

2. GENERAL STATEMENT
Propylene is a source material for producing polypropylene, from which automotive components,
packaging films, food containers, trays, medical utensils and other plastic products that are often
encountered in our daily lives have been made. The substance takes the form of a clear gas undernormal temperatures, and possesses a slight aroma. It is a typical basic petrochemical productproduced together with ethylene, by thermally decomposing naphtha made from crude oil attemperatures of 800ºC or higher. As an organic compound with a double bond, it is used as a basic
source material for polypropylene, acrylonitrile, acrylic acid and other propylene products. On theother hand, the gas is extremely combustible and flammable. As such, it is important to keep itaway from heat, sparks, open flames and other fire sources. Additionally, note that its inhalation
could induce drowsiness and dizziness.

4. USES AND APPLICATIONS
Main uses

It is used as a raw material for petrochemical products such as
polypropylene, acrylonitrile, acrylic acid, and propylene oxide.
Polypropylene is widely used as a synthetic resin with many excellent
properties such as light weight, processability, durability, heat resistance,and chemical resistance for automotive bumpers, instrument panels, foodtrays, home appliances, and medical devices.

• Not applicable: Since the priority of physical state, chemical structure, chemical property, and hazard items used inthe GHS classification procedures does not fall under the category, it is not subject to the classification for thecategory.
• Not classified: Sufficient information has been obtained to implement the GHS classification, and as a result of theclassification, it does not fall under any of the hazard categories specified in the GHS.

8. EXPOSURE

exposures

Precautions

Exposure potentials through main uses
Since the company’s product is produced in a closed process, thepotential for occupational exposure is extremely limited. Polypropylene,propylene oxide and other products made from the substance aremanufactured in closed processing systems. As such, exposure toworkers who manufacture polypropylene and propylene oxide, etc., isextremely limited. However, workers could inhale the substance, or
their skin and eyes could come in direct contact with it when sampling,etc.
The substance is not used in any case by general consumers.
Since the substance is normally manufactured and used in a closed
process, its emission into the environment is extremely limited. The
substance exists in the form of gas under normal temperatures andpressures, and is believed to be dispersed in the air when discharged
into the environment. Further, the substance could be promptly
decomposed in the air.
If there is a possibility of exposure in other uses, take appropriate
measures with reference to recommended risk management measures.

9. RISK MANAGEMENT RECOMMENDATIONS
Recommended risk management measures can minimize risks to workers, consumers, and theenvironment from Section 8 exposure scenarios.
DetalsWorkerRisk management recommendations
Wear appropriate protective masks, as well as clothes and protective
gloves made of materials impermeable to propylene, when sampling thesubstance.
The American Conference of Governmental Industrial Hygienists(ACGIH) has published the occupational threshold limit value of 500
ppm (time-weighted average; TWA) for this substance. Therefore, in
manufacturing places or places using the substance, it is required tomanage and control an environmental concentration of the substance

Consumer

EnviaronmentSpecial notes(emergency measuresin case of leakage, etc.)Precautions

to keep it below the threshold limit value.
Managers responsible for processes should educate workers on theselection of appropriate protective gear, their proper usage and how tomanage their working places.
Precautions
The operation manager should educate operators about the selectionof appropriate protective equipment, proper usage method, and control
method of the work site.
Normally, this substance is not used by general consumers, but if it isused, the same risk management measures as those for "workers"
above should be taken.
The substance could affect the environment if leaked. Therefore,
implement preventive measures against leakage and pay attention to
the daily management and handling of the substance.
Keep away from heat, sparks, open flames, high-temperature objects
and other fire sources, because the substance is extremely
combustible and flammable.
Wear conductive shoes that prevent static electricity while at work.
When ethylene manufacturing facilities are open (for regular repair,etc.), oxygen shortage could result when the atmosphericconcentration of ethylene is high. Measure the oxygen concentration
before entering the area, and wear appropriate protective gear asnecessary.
For normal handling, emergency response, disposal, and transportation
control measures, refer to sections 4, 5, 6, 7, 8, 13, and 14 of the SDS
issued by Resonac Corporation.
