Our Orange Silica Gel is not impregnated with cobalt chloride, it is the latest product that can replace the blue silica gel indicator. The composite dyeing agent without pollution to the environment has been successfully adopted during the manufacturing process of the orange silica gel indicator. In this way, it has prevent the cobalt chloride from polluting the environment from the very beginning. There are two types with the orange silica gel indicator. One is Orange Dark green Type, it discolors from orange into dark green during the process of moisture adsorption; another is Orange - Colourless Type , it discolors from orange into light green when adsorbing moisture. Both the orange silica gel indicators have much more adsorption capacity than that of the blue Indicating silica gel. The orange silica gel Indicator has won unprecedented acknowledgement and praise from the clients since its introduction in European and American markets. Particle Size : We offer various particle size ranges as below: In mesh Size :1/2, 3/4, 3/6, 3/8, 5/8, 9/16, 16/30, 30/60 mesh In mm. :10-20, 8-10, 6-10, 4-10, 6-8, 4-8, 3-8, 4 -6, 3-5, 2-5, 1.5-2, 1-2, 1-1.5 mm.

Cat. 2 Risk Phrases R49 May cause cancer by inhalation. Hazards Identification The product is very adsorbent and may have a drying effect on skin and eyes. Sensitisation of skin and respiratory system is possible. Any dust could be a nuisance. Evolves heat on contact with water. Cobalt Chloride has been classified by IARC (International Agency for Research on Cancer) in Group 2B. Possibly carcinogenic to humans. Very toxic to aquatic organisms. May cause long term adverse effects in the environment. First Aid Measures 1. After inhalation: remove to fresh air.2. After skin contact: wash with water, if skin irritation persists seek medical advice.3. After eye contact: flush with water, if irritation persists seek medical advice.4. After ingestion: give water to drink, seek medical advice. Fire Fighting Measures 1. Products of combustion: not combustible.2. Fire fighting Pocedures/extinguishing media : not applicable, unused material will not burn. Use media appropriate for surrounding fire. Accidental Release Measures 1. Personal precautions: respiratory protection if dusty, eye and hand protection.2. Environmental precautions: try to prevent material from entering drains or watercourses. Advise authorities if spillage has entered watercourse or sewer.3. Methods for cleaning up: sweep up or preferably vacuum up and collect in suitable container for recovery or disposal. Avoid raising dust. Handling and Storage 1. Precautions during handling: avoid raising dust, vacuum up dust sources, prevent static electric sparks. Beads may be slippery.2. Precautions during storage: store in sealed containers in a dry place. Exposure Controls/Personal Protection1.

Effects of exposure:Eyes dust may cause irritation.Skin heat may be evolved when in contact with water. May have a drying effect.Skin sensitisation cobalt compounds are skin sensitisers. Carcinogenicity amorphous silica is not classified as carcinogenic to humans. There is limited evidence of cobalt chloride in experimental animals. Ecological/Biological Information Amorphous silica is chemically and biologically inert. It is not degradable. By its insolubility in water there is a separation at every filtration and sedimentation process. Cobalt is a List II substance in EEC Directive 76/464 for the control of dangerous substances in the aquatic environment. This product must not be allowed to contaminate soil and water.
