PERSONAL PROTECTIVE MEASURES |
| ENGINEERING CONTROLS: Where possible, provide general mechanical and/or local exhaust ventilation to prevent release of airborne dust into the work environment. PERSONAL PROTECTIVE EQUIPMENT EYES AND FACE: Appropriate eye and face protection equipment (ANSI Z87 approved) should be selected for the particular use intended for this material. Safety glasses with side shields are recommended. RESPIRATORY: Whenever dust in the worker’s breathing zone cannot be controlled with ventilation or other engineering means, workers should wear respirators or dust masks approved by NIOSH/MSHA, EU CEN or comparable certification organization to protect them against airborne dust PROTECTIVE CLOTHING: Dry product is generally non-irritating to intact skin. However, this product can be irritating where skin has been damaged and can create skin irritation |
|
MEASURES IN CASE OF ACCIDENTS |
| EYES: Flush with plenty of water. Get medical attention if irritation occurs and persists. SKIN: Wash with plenty of soap and water. Get medical attention if irritation occurs and persists. INGESTION: Drink plenty of water. Never give anything by mouth to an unconscious person. If any discomfort persists, obtain medical attention. INHALATION: Remove to fresh air. If breathing difficulty or discomfort occurs and persists, obtain medical attention. NOTES TO MEDICAL DOCTOR: Internal toxicity is low. Treatment is symptomatic and supportive. |
|
HANDLING AND STORAGE |
| HANDLING: Use air conveying/mechanical systems for bulk transfer to storage. For manual handling of bulk transfer use mechanical ventilation to remove airborne dust from railcar, ship or truck. Use approved respiratory protection when ventilation systems are not available. Selection of respirators is based on the dust cloud generated. STORAGE: Protect from excessive heat and moisture. Store away from acids. COMMENTS: Use general room dilution or local exhaust ventilation when excessive dust is expected in the work environment. |
