SECTION 7. HANDLING AND STORAGE
Precautions for safe handling
Advice on safe handling Protect from moisture: Reacts with water. Ensure adequate ventilation, especially in
Conditions for safe storage, including any incompatibilities Conditions Keep away from heat, sparks, flame and other sources of ignition (i.e., pilot lights, electric
motors and static electricity). Store away from flammable substances, reducing agents,
metal powders, and organic materials.
Incompatible materials Water, alcohols, phenols, and amines. Rubber, coatings, and some plastics. Flammable
substances, reducing agents, metal powders, and organic materials. Reacts with metals to
produce heat and corrosive gases.
SECTION 8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Chemical Name ACGIH TLV OSHA PEL
Hafnium Dinitrate Oxide
- - Appropriate engineering controls
Engineering Controls Avoid generation of uncontrolled particles.
Individual protection measures, such as personal protective equipment
Eye/face protection If a risk of eye injury or irritation is present, appropriate eye protection is recommended; for
example, tight-fitting goggles, foam-lined safety glasses, face shield, or other protective
equipment that shields the eyes.
Skin and body protection Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls,
as appropriate, to prevent skin contact.
Respiratory protection When particulates/fumes/gases are generated and if exposure limits are exceeded or
irritation is experienced, proper approved respiratory protection should be worn.
Positive-pressure supplied air respirators may be required for high airborne contaminat
concentrations. Respiratory protection must be provided in accordance with current local
General Hygiene Considerations Handle in accordance with good industrial hygiene and safety practice.
