GPS/JIPS Safety Summary
1. Product NAMEAlGaAs/GaAs chip (SH and DH type）

2. GENERAL STATEMENT
Gallium arsenide, the main ingredient of this product, is arsenide of gallium. The composition
formula of this product is expressed as GaAs. Since it is a compound semiconductor, it isfrequently used as a material of semiconductor elements by utilizing its characteristics.
Gallium arsenide is classified into IARC (International Agency for Research on Cancer) Group 1
and ACGIH A3, suggesting its carcinogenicity. For this reason, dispose of semiconductors
containing gallium arsenide in accordance with national and local regulations. In addition, since
there is a risk of inhalation of dust if it is pulverized or crushed, it is necessary to wear
appropriate protective equipment to prevent inhalation.

Section 2 and 11 of SDS issued by Resonac
Photonics Corporation• GHS (Globally Harmonized System of Classification and Labelling of Chemicals): A system that classifies chemicals
according to the type and degree of hazards, labels the information, and provides safety data sheets according to
globally harmonized rules.
• Not applicable: Since the priority of physical state, chemical structure, chemical property, and hazard items used in
the GHS classification procedures does not fall under the category, it is not subject to the classification for the
category.
• 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. It is considered to be a lower
hazard.
• Classification not possible : There is not enough information for GHS classification, and classification is not possible.

Environmental exposures

Precautions

Exposure potentials through main uses
This product is manufactured and used in closed batch processes
or other processes where there is a potential for exposure to the
product, but in operations, such as during maintenance, sampling,and equipment failure, there is a potential for dermal and inhalation
exposure to workers (PROC 3 and 4).
There is potential for dermal and inhalation exposure in operatorsin the transfer of substances and preparations from ships or large
capacity containers in small containers or specialized equipment[e.g., dust/vapor/aerosol generation, spills, equipment cleaning](PROC 8b, 9).
This product is not used directly by general consumers.
The product is manufactured and used in closed systems or otherpotentially exposed processes. Therefore, in the production
process, the product may be released primarily to the air andwater environment (ERC 1).
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
Technical measures:
Chronic toxicity such as carcinogenicity and reproductive toxicity
has been identified for this product. Handle the product in a roomwith forced general ventilation using local exhaust ventilation byusing appropriate protective equipment to protect operators fromdust. Always wash your hands after handling the product.
Local and general ventilation:
The product should be handled in a place where forced general
ventilation is possible with local exhaust ventilation. In addition,
since there is a possibility of exposure during the transfer
operation to containers, etc., perform the operation in a room
where forced general ventilation is possible with local exhaust

Special notes (emergency
measures in case of leakage,etc.)

Acceptable concentration:
Gallium arsenide: The excess cancer risk levels 10-3: 3 μg/m3,
10-4: 0.1 μg/m3 (inorganic arsenic compound [as As]) are disclosed
by Japan Society for Occupational Health, and TLV-TWA (timeweighted average) 0.01 mg/m3 (as arsenic) and TWA 0.0003 mg/m3(inhalational) are disclosed by ACGIH (American Conference ofGovernmental Industrial Hygienists).
Aluminum arsenide • gallium: 0.003 mg/m3 (as arsenic) is disclosed
by Japan Society for Occupational Health, and TLV-TWA 0.01
mg/m3 (as arsenic) is disclosed by ACGIH.
Manage and control below these values.
Protective equipment:
When handling the product, wear respiratory protective equipment(a certified dust mask [with a collection rate of 95% or higher]),chemically resistant rubber gloves (APF20 [with a protection rateof 95%]), protective glasses, and protective clothing to avoid skincontact. In addition, wear face protective equipment according to
the use status.
[Example of protective equipment]
Respiratory protective equipment: dust mask (mask with collection
rate of 95% or higher)
Hand protective equipment: chemically resistant rubber gloves(APF20 [protection rate 95%])
Eye protective equipment: protective glasses
Skin and body protective equipment: Protective clothing
Precautions
The operation manager should educate operators about the
selection of appropriate protective equipment, proper usage
method, and control method of the work site.
Since the substance is not used by general consumers, thepossibility of exposure to consumers is extremely low.
Install appropriate wastewater treatment facilities and exhaustgas treatment facilities. In addition, take measures to prevent
leakage, and pay attention to periodic confirmation of discharge
volume, daily control, and handling.
Precautions for human, protective equipment, and emergency
measures:In case of leakage, wear appropriate protective equipment(respiratory protective equipment, protective clothing, rubber
gloves, and eye or face protective equipment), and remove it fromthe windward side using a vacuum cleaner or dust removal.
Environmental precautions:
Do not discharge product into the environment such as drains orrivers.
In case of leakage, immediately remove it from the windward sidewith a vacuum cleaner and dust removal. In addition, prepare
appropriate fire extinguishing equipment (carbon dioxide, dry sand,water spray, and powder) in case of ignition.
