8. Exposure controls and personal protection

8.1 Engineering controls

Ventilation:
Use only with adequate ventilation.

Local exhaust:
In case of dust formation: ( To maintain concentration below TLV. ) Local exhaust ventilation which meets the requirements of
ANSI Z9.2 is recommended to control airborne contaminants at the point of use.

8.2 Associate substances with specific control parameters such as limit values

Maximum airborne concentrations at the workplace:
CAS No. Material Type mg/m
3
ppm Dust fract.
7631-86-9 Silica, amorphous OSHA PEL 0.8
Particulates not otherwise classified ACGIH TWA 10.0 Inhalable
dust/mist
Particulates not otherwise classified ACGIH TWA 3.0 Respirable
dust/mist

Re Silica, amorphous: The exposure limits given for CAS-No. 7631-86-9 cover all types of synthetic amorphous silica; it appears,
that there is an error in the OSHA PEL entry for amorphous silica. There should have been a footnote to the Z-3 Table indicating
that the percent SiO2 in formula (80 mg/m3 + % SiO2) refers to crystaline silica content and not to amorphous silica. For
evaluation of U.S. exposure measurements WACKER recommends use of the current NIOSH REL (6 mg/m3) instead of the old
Z-3 Table entry.

Re Particulates not otherwise classified: The value is for particulate matter containing no asbestos and < 1% crystalline silica (ACGIH). 8.3 Personal protection equipment (PPE) Respiratory protection: In case of dust formation: A NIOSH approved particulate respirator with a P95 or higher rating. Hand protection: Recommendation: rubber gloves . Eye protection: Recommendation: Safety glasses with side shields or chemical safety goggles. Other protective clothing or equipment: Barrier cream may be used to prevent dryness of skin. 8.4 General hygiene and protection measures: Do not breathe dust/vapor/mist/gas/aerosol. Wash thoroughly after handling. Safety Data Sheet Material: 60004600 HDK N20 HYDROPHILIC PYROGENIC SILICA Version: 2.1 (US) Date of print: 06/25/20 15 Date of last alteration: 06/24/2015 Page: 4/8 9.

EYE PROTECTION GUIDELINES: …………………………………………….. Safety glasses with side shields, or goggles if necessary.

SKIN PROTECTION GUIDELINES: ……………………………………………. Liquid-proof gloves (such as neoprene or nitrile) should be used to prevent
skin irritation. Barrier creams can be used effectively.

RESPIRATORY PROTECTION GUIDELINES: …………………………….. When ventilation cannot be made adequate enough to keep exposures
below established limits, use a NIOSH approved respirator with particulate filter, such as a N95 or greater, depending on specific workplace
conditions. Consult with your respirator and cartridge supplier to ensure proper selection of respirator and cartridge based on ingredients listed in
Section 3 and specific workplace conditions. Use and select a respirator according the guidelines established in OSHA 1910.134 or other

FIRE-FIGHTING MEASURES Suitable Extinguishing media: Apply alcohol type or all-purpose type foams by manufacturers recommended techniques for large fires. Use carbon monoxide or dry chemical media for small fires. Do not direct a solid stream of water or foam into burning molten material; this may cause spattering and spread of fire. Extinguishing media to be avoided: None Unusual fire and explosion hazards: Avoid dispersion of dust in air to reduce potential of dust ignition / explosion. Special protective equipment for fire fighters: Use self-contained breathing apparatus and protective coating. 6. ACCIDENTAL RELEASE MEASURES Personal precautions: Wear suitable protective clothing. Methods for cleaning up: Ventilate with fresh air. Collect as much of the spilled material as possible. Use wet sweeping or water to avoid dusting. Collect and place in a closed container. Dispose as approved by your State Regulations. Page 3 of 5 7. HANDLING AND STORAGE 7.1 Handling General precaution: For industrial and professional use only. Avoid dispersion of dust in air. Electrically bond and ground equipment. Avoid sparks and flame under dust conditions. Use with adequate ventilation. Ventilation: Special, local ventilation is recommended in areas where containers are opened and their containers are discharged or in any areas where dusting conditions may occur. Other precaution {Caution] May undergo spontaneous smouldering if stored or heated in bulk above 35 o C under conditions allowing air ingress to the product. Store package material in a cool, well-ventilated area. Do not store in the sun. Do not dry in package use special drying instructions as below. Microspheres will undergo oxidation at elevated temperatures. Due to the microspheres excellent insulating characteristics, the internal temperature of the mass can increase to the point where spontaneous ignition and smouldering can occur. The temperature at which this occurs is a function of the geometry, amount of material being heated and available oxygen. Smouldering appears as a soft glow similar to burning charcoal. Drying instructions for the Phenoset microspheres: To reduce the moisture content of this product to less than 4%, dry a two-inch layer of the product at a maximum temperature of 75 o C for 24 hours.
