General advice No acute or delayed symptoms are expected under normal conditions of use and with

proper personal protective equipment (PPE). Do not breathe dust. Get medical attention if

irritation or other symptoms occur.

Inhalation Move victim to fresh air.

Eye contact Rinse eyes. Keep eye wide open while rinsing.

Explosion data

Sensitivity to mechanical impact None.

Sensitivity to static discharge None.

Special protective equipment and

precautions for fire-fighters Firefighters should wear self-contained breathing apparatus and full firefighting turnout Use personal protection equipment.

6. Accidental release measures

Personal precautions, protective equipment and emergency procedures

Personal precautions Avoid generation of dust. Do not breathe dust. If respirator is required, use of a

MSHA/OSHA/NIOSH/STPS approved respirator is recommended. Spilled materials may

cause slippery conditions when wet. Care should be exercised when walking on spills on

floors or concrete pads.

Other information Refer to protective measures listed in Sections 7 and 8.

Methods and material for containment and cleaning up

Methods for containment Keep out of drains, sewers, ditches and waterways.

Methods for cleaning up Avoid dry sweeping and use water spraying or vacuum cleaning systems to prevent

airborne dust generation. Vacuum, pump or scoop spilled material into containers for

reclaiming or disposal. Do not discharge into drains, watercourses or onto the ground.

7. Handling and storage

Precautions for safe handling

Advice on safe handling Avoid generation of dust. Do not breathe dust. Handle in accordance with good industrial

hygiene and safety practice. Ensure adequate ventilation. In case of insufficient ventilation,

wear suitable respiratory equipment. Product on floor when wetted will become slippery and

may present a hazard; wear anti-slip boots.

Conditions for safe storage, including any incompatibilities

Storage Conditions Keep containers tightly closed in a dry, cool and well-ventilated place.

toxicity for which no TLV has been established. See Appendix B of the TLV booklet for

guidelines.

Appropriate engineering controls

Engineering controls Minimize airborne dust generation. Ensure adequate ventilation, especially in confined

areas. Use process enclosures, local exhaust ventilation or other engineering controls to

keep airborne levels below specified exposure limits. Use proper respiratory and personal

protective equipment. MSHA/OSHA/NIOSH/STPS approved respirator recommended.

Individual protection measures, such as personal protective equipment

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

Hand protection Wear suitable gloves. Appropriate protection (e.g. gloves, barrier cream) is recommended

for workers who suffer from dermatitis or sensitive skin.

Skin and body protection Wear suitable protective clothing.

Respiratory protection When workers are facing concentrations above the exposure limit they must use appropriate

certified respirators.

Environmental exposure controls Avoid creating dust. Do not allow into any sewer, on the ground or into any General hygiene considerations Do not breathe dust. Wash hands before breaks and immediately after handling Barrier creams may help to protect the exposed areas of skin. Do not eat, drink or smoke

when using this product.
