General information 

5. Fire-fighting measures 

Ensure that medical personnel are aware of the material(s) involved, and take precautions to protect themselves. 

Suitable extinguishing media Water fog. Foam. Dry chemical powder. Carbon dioxide (CO2). Unsuitable extinguishing media Do not use a water jet as an extinguisher, as this will spread the fire. Specific hazards arising from fire, and gases hazardous to health may be formed. 

Special protective equipment Self-contained breathing apparatus and full protective clothing must be worn in case of fire. and precautions for firefighters 

Fire fighting Move containers from the fire area if you can do so without risk. equipment/instructions 

Specific methods Use standard firefighting procedures and consider the hazards of other involved materials. General fire hazards No unusual fire or explosion hazards were noted. 

6. Accidental release measures 

Personal precautions, protective Keep unnecessary personnel away. For personal protection, see section 8 of the SDS. equipment and emergency procedures. Methods and materials for containment and cleaning up.

Stop the flow of material, if this is without risk. Following product recovery, flush area with water. For waste disposal, see section 13 of the SDS. 

Environmental precautions Avoid discharge into drains, water courses or onto the ground.

7. Handling and storage 

Precautions for safe handling Avoid prolonged exposure. Use care in handling/storage. 

Conditions for safe storage, including any incompatibilities 

Store in the original tightly closed container. Store away from incompatible materials (see Section 10 of the SDS). 

8. Exposure controls/personal protection 

Occupational exposure limits 

US. ACGIH Threshold Limit Values 

Material Type Value 

Hafnium Nitride (CAS TWA 0.5 mg/m3 25817-87-2) 

US. NIOSH: Pocket Guide to Chemical Hazards 

Material Type Value 

Hafnium Nitride (CAS TWA 0.5 mg/m3 25817-87-2) 

Biological limit values No biological exposure limits noted for the ingredient(s). 

Appropriate engineering controls 

Good general ventilation (typically 10 air changes per hour) should be used. Ventilation rates should be matched to conditions. If applicable, use process enclosures, local exhaust ventilation, or other engineering controls to maintain airborne levels below recommended exposure limits. If exposure limits have not been established, maintain airborne levels to an acceptable level. 

Control parameters Follow standard monitoring procedures. 

Individual protection measures, such as personal protective equipment 

Eye/face protection Wear safety glasses with side shields (or goggles). 

Skin protection 

Hand protection Wear appropriate chemical resistant gloves. 

Other Wear suitable protective clothing. 

Respiratory protection In case of insufficient ventilation, wear suitable respiratory equipment. Thermal hazards Wear appropriate thermal protective clothing, when necessary. 

General hygiene considerations 

Always observe good personal hygiene measures, such as washing after handling the material and before eating, drinking, and/or smoking. Routinely wash work clothing and protective equipment to remove contaminants.
