3. PRECAUTIONS FOR USE
3.1 Exposure Standards
An exposure standard has not been established for this product. However, the following is recommended for nuisance dusts : Dusts not otherwise classified : TWA 10 mg/m3
3.2 Engineering Controls
Ensure adequate ventilation to maintain exposure levels below standards, including the use of local exhaust or process enclosure.
3.3 Personal Protection
Eye protection : splash-proof or dust-proof safety goggles and faceshield. Gloves : appropriate impervious and chemical-resistant gloves. Respiratory protection : specific respirator should be selected based on contamination levels found in the workplace and jointly approved by the National Institute for Occupational Safety and Health (NIOSH) and the Mine Safety and Health Administration (MSHA). Wash hands and face thoroughly after handling and before work breaks, eating, drinking, smoking and using toilet facilities.
3.4 Flammability
Product stable under normal conditions, SAFE HANDLING INFORMATION
4.1 Storage / Transport
Clean and dry process piping and equipment before using the product. Never return unused product to original container. Keep away from incompatible products. Containers and equipment used to handle the product should be used exclusively for that product. Avoid any contact with water or humidity. Store in a cool and dry area (protect from direct sunlight). Keep away from heat and humidity sources. Avoid contact with incompatible materials such as water, acids, bases, salt of metals, reducing agents, organic materials and flammable substances.
4.2 Packaging / Labelling UN No. 1479 Class 5.1 Sub Risk None Allocated Hazchem Code 1Y Pack Group II EPG No. 31 Shipping Name OXIDISING SOLID, N.O.S. (SODIUM PERCARBONATE) Hazard IRRITANT
Risk Phrases R36/37/38 Irritating to eyes, respiratory system and skin.
Safety Phrases S22 Do not breathe dust. S24/25 Avoid contact with skin and eyes.
4.3 Spills and Disposal
Spills
Clean-up personnel should wear protective clothing as outlined in Section 3.3. Avoid raising dusts. Avoid materials and products which are incompatible. Avoid direct contact of the product with water.
Collect the product with suitable means, shovel or sweep, avoiding dust formation. All receiving equipment should be clean, dry, vented, labelled and made of material which is compatible with the product. Do not return spilled or contaminated material to inventory. Clean the area with large quantities of water.
Disposal
Dispose of waste by landfill in accordance with all Local, State and Federal regulations at an approved waste disposal facility. The empty and clean containers are to be recycled or disposed of in conformity with local regulations.
4.4 FIRE AND EXPLOSION HAZARD Fire / Explosion
Oxidising substance which can be decomposed by water, direct sources of heat, catalysts etc. Decomposition releases oxygen and heat which can support combustion and cause pressure bursts in confined spaces or containers. Decomposition in the presence of organic materials can be highly exothermic and may cause combustion. Avoid contact with incompatibles such as water, acids, bases, salt of metals, reducing agents, organic materials, flammable substances. Sodium Carbonate Peroxyhydrate dissociates into Sodium Carbonate and Hydrogen Peroxide in aqueous solution, and dissociated Hydrogen Peroxide decomposes into water and free oxygen.
Extinguishing Media
Fire-fighters should wear full protective clothing including self-contained breathing apparatus. In case of fire use water only. DO NOT use dry chemical, carbon dioxide or halogenated extinguishing agents. Evacuate all non-essential personnel from fire area. Intervention only by capable personnel who are trained and aware of the hazards of the product. Move unaffected product to a safe area if safe to do so. Apply plenty of water to extinguish the fire. 5 OTHER INFORMATION
