Guidance on Safe Use
Administrative data
First-aid measures
- inhalation: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention.
- ingestion: Do not induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. If potentially dangerous quantities of this material have been swallowed, call a physician immediately.
- skin contact: In case of contact, immediately flush skin with plenty of water. Remove contaminated clothing and shoes. Wash clothing before reuse. Clean shoes thoroughly before reuse. Get medical attention.
- eye contact: In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Get medical attention immediately.
See section Toxicological information of MSDS for more detailed information on health effects and symptoms.
Fire-fighting measures
- Extinguishing media: Use an extinguishing agent suitable for the surrounding fire.
- Special exposure hazards: No specific hazard
This material is toxic to aquatic organisms. Fire water contaminated with this material must be contained and prevented from being discharged to any waterway, sewer or drain.
See section Toxicological information of MSDS for more detailed information on health effects and symptoms.
- Hazardous thermal decomposition products: These products are sulfur oxides (SO2, SO3 etc.). Some metallic oxides.
- Special protective equipment for firefighters: Fire-fighters should wear appropriate protective equipment and self-contained breathing apparatus (SCBA) with a full face-piece operated in positive pressure mode.
Accidental release measures
- Personal precautions: Immediately contact emergency personnel. Keep unnecessary personnel away. Use suitable protective equipment.
- Environmental precautions: Avoid dispersal of spilled material and runoff and contact with soil, waterways, drains and sewers.
- Methods for cleaning up: If emergency personnel are unavailable, vacuum or carefully scoop up spilled material and place in an appropriate container for disposal by incineration. Avoid creating dusty conditions and prevent wind dispersal.
Handling and storage
- Handling: Do not ingest. Avoid contact with eyes, skin and clothing. Keep container closed. Use only with adequate ventilation. Avoid breathing dust. Avoid contact of spilled material and runoff with soil and surface waterways. Avoid exposure. Use suitable protective equipment (section Exposure Control / personal protection). Avoid generation of dust.
- Storage: Store on a liquid tight surface, provided with a collection system for the drainage water. Prevent dust generation during stockpiling.
- Packaging materials recommended: This material is delivered in bulk. No specific packaging is required but avoid dusty conditions and avoid exposure.

Exposure controls / personal protection
*) Occupational exposure limits
- Manganese dioxide: ACGIH TLV (United States, 1/2006). Notes: Substances for which the TLV is higher than the OSHA Permissible Exposure
Limit (PEL) and/or the NIOSH Recommended Exposure Limit (REL). See CFR 58(124) :36338-33351, June 30, 1993, for revised OSHA PEL. See Notice of Intended changes. TWA: 0,2 mg/m3 8 hour/hours. Form: All forms
- Gypsum: INRS (France, 1/1999). VME: 10 mg/m3 8 hour/hours.
- Lead dioxide: INRS (France, 2/2005). Notes: As Pb Regulatory binding exposure limits VME: 0,1 mg/m3 8 hour/hours. Form: All forms
- silica: ACGIH TLV (United States, 1/2006). Notes: Particulates (Insoluble) Not Otherwise Specified (PNOS) TWA: 10 mg/m3 8 hour/hours. Form: Inhalable
- Ferrous sulphate: ACGIH TLV (United States, 1/2006). TWA: 1 mg/m3 8 hour/hours. Form: All forms
*) Exposure controls:
- Occupational exposure controls: Use process enclosures, local exhaust ventilation or other engineering controls to keep airborne levels below recommended exposure limits. If user operations generate dust, fumes or mist, use ventilation to keep exposure to airborne contaminants below the exposure limit.
- Respiratory protection: Use a properly fitted, particulate filter respirator complying with an approved standard if a risk assessment indicates this is necessary. Respirator selection must be based on known or anticipated exposure levels, the hazards of the product and the safe working limits of the selected respirator.
- Skin protection/ hand protection: Chemical-resistant, impervious gloves complying with an approved standard should be worn at all times when handling chemical products if a risk assessment indicates this is necessary.
Personal protective equipment for the body should be selected based on the task being performed and the risks involved and should be approved by a specialist before handling this product
- Eye protection: Safety eyewear complying with an approved standard should be used when a risk assessment indicates this is necessary to avoid exposure to liquid splashes, mists, gases or dusts.
*) Hygiene measures:
General: Eating, drinking and smoking should be prohibited in areas where this material is handled, stored and processed. Workers should wash hands and face before eating, drinking and smoking.
Stability and reactivity
- stability: The product is stable.
- Hazardous decomposition products: These products are sulfur oxides (SO2, SO3 etc.). Some metallic oxides.
Disposal considerations
Methods of disposal: The generation of waste should be avoided or minimized wherever possible. Avoid dispersal of spilled material and runoff and contact with soil, waterways, drains and sewers. Disposal of this product, solutions and any by-products should at all times comply with the requirements of environmental protection and waste disposal legislation and any regional local authority requirements.
- European waste catalogue (EWC): Not available.
- Hazardous waste : The classification of the product may meet the criteria for a hazardous waste.
