GPS/JIPS Safety Summary
1. PRODUCT NAME
BN-DX™ GRAIN

2. GENERAL STATEMENT
BN-DX™ GRAIN (cubic boron nitride) is used as a grinding and cutting tool material for iron-based
high-hardness materials, making use of its high hardness secondary to diamond and its nonreaction with iron. We manufacture sintering bodies from abrasive grains of cubic boron nitride andhave a grade that is applicable for grinding/cutting applications of various materials.
It is harmful to the human body and may cause allergy, asthma or dyspnea when inhaled,suspected carcinogenicity, or allergic skin reactions when adhered to the skin. Inhalation may
cause renal and respiratory disorders, and prolonged or repeated exposure may cause respiratory
disorders. For this reason, it is necessary to wear appropriate protective equipment in a wellventilated place to protect the eyes, protect the skin, and prevent inhalation.

Section 2 and 11 of SDS issued by Resonac
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.

8. EXPOSURE

Consumer exposures
Environmental exposures

Precautions

Exposure potentials through main uses
The product is manufactured and used in used in synthesis orcompounding operation in closed batches, but there is a potential
for dermal or inhalation exposure in operators in case ofmaintenance, sampling, equipment failure, etc. (PROC 3).
During batch and other process operations, there is a potential fordermal and inhalation exposure to operators during maintenance,
sampling, filling, emptying, and equipment failure (PROC 4).
There is a potential for dermal and inhalation exposure in
operators during blending/mixing operation in batches in theformulation and manufacture of articles (PROC 5).
There is a potential for dermal or inhalation exposure in operators
in association with dust/vapor/aerosol generation, spillage,
cleaning of equipment, etc. in the transfer of substances or
preparations to ships and large-capacity containers in dedicatedequipment or in the transfer of substances or preparations tosmall-capacity containers under conditions designed to minimize
spillage (PROC 8b, 9).
This product is not used directly by general consumers.
Although emission to the environment is limited because theproduct is typically manufactured and used in a closed process, theproduct can be released primarily into the atmospheric and water
environment during the manufacturing process (ERC 1).
The product is used as a processing aid in manufacturing andcompounding processes and is highly released primarily to theatmosphere and water environment. It may also be released into
the soil environment (ERC 4).
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.
DetalsWorkerConsumer
Environment

Risk management recommendations
Technical measures:
Handle the product in a room with forced general ventilation using
local exhaust ventilation by wearing appropriate protective
equipment to protect operators from dust. Always wash your hands
after handling the product. Handle the product with care to avoid
generation of aerosol and dust and avoid adhesion of the productto eyes, skin, and clothing.
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 ventilation.
Acceptable concentration:• BN-DX™ GRAIN: Control concentration 3 mg/m³ (when the freesilicic acid content is 0%)• Cobalt: Control concentration 0.02 mg/m³ (as cobalt), Japan
Society for Occupational Health acceptable concentration 0.05
mg/m³ (as cobalt), and ACGIH (American Conference ofGovernmental Industrial Hygienists) TLV-TWA (time-weighted
average) 0.02 mg/m³ (as cobalt)• Nickel: Japan Society for Occupational Health exposure limit 1
mg/m³ (as nickel) and ACGIH (American Conference ofGovernmental Industrial Hygienists) TLV-TWA (time-weighted
average) 1.5 mg/m³ (as nickel)
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]),protective gloves (APF20 [with a protection rate of 95%]),protective glasses, and protective clothing to avoid skin contact.
[Example of protective equipment]
Respiratory protective equipment: dust mask (mask with collection
rate of 95% or higher)
Hand protective equipment: protective gloves (APF20 [protection
rate 95%])
Eye protective equipment: protective glasses
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

measures in case of leakage,etc.)

Precautions

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, protective
gloves, and eye and face protective equipment), and remove theproduct using a vacuum cleaner.
Environmental precautions:
Do not discharge product into the environment such as drains orrivers. If it leaks, immediately remove it with a vacuum cleaner.
For normal handling, emergency response, disposal, andtransportation control measures, refer to sections 4, 5, 6, 7, 8, 13,
and 14 of the SDS issued by Resonac Corporation.
