| Hazards Identification | |
| Health Effects: | |
| Skin Contact | May cause slight irritation, especially with repeated or prolonged exposure. |
| Eye contact | May cause some irritation which should cease on removal of the product. |
| Inhalation | May cause some irritation to the respiratory system if dust is inhaled. |
| Ingestion | Low toxicity product. |
| Physical / Chemical Effects | Not classified as hazardous by physical / chemical properties. This type of product has a tendency to create dust if roughly handled. This product does not burn readily, but as with many organic powders, flammable dust clouds may be formed in air. Avoid creating dust and keep away from sources of ignition. Very slippery when wet. |
| First Aid Measures | |
| Skin Contact | Wash contaminated area with soap and water. Contaminated clothing should be washed before re-use. |
| Eye contact | Irrigate the eye with water for 15 minutes. If there is any irritation obtain medical attention immediately. |
| Inhalation | Remove the casualty to fresh air. Clear any blocked airways. If recovery is delayed seek medical advice. |
| Ingestion | Do not make the casualty vomit. If unconscious do not give anything by mouth. Check for breathing and pulse, if present, place in the recovery position and obtain medical attention. If conscious rinse out the mouth with water. Give 1 pint to drink immediately and repeated drinks of water at the rate of a cupful (1/3 pint) every 10 minutes. Obtain medical attention immediately. |
| Fire Fighting Measures | |
| Extinguishing Media | Foam, dry powder, carbon dioxide, in preference to water spray. (The product becomes very slippery when wet.) |
| Special Protective Equipment for Firefighters | As for all fires involving chemicals: chemical protection suit, suitable gloves and boots, and self-contained breathing apparatus. |
| Accidental Release Measures | |
| Personal Precautions | Avoid dust formation. Use personal protective equipment, effective dust mask. |
| Method for Cleaning Up | Sweep up and shovel into suitable containers for disposal. Residues or small spillages should be hosed away completely with plenty of water. Spilled product which becomes wet or spilled aqueous solutions create a hazard because of their slippery nature. The spillage should be contained with earth or sand and removed for disposal. |
| Handling & Storage | |
| Handling Precautions | As with many organic powders flammable dust clouds may be formed. Avoid creating dust and keep away from sources of ignition. Do not breathe dust. Do not eat, drink or smoke whilst handling this product. Remove contaminated clothing immediately and launder before reuse. Wash hands after use. |
| Storage Conditions | Avoid wet, damp and humid conditions. Keep in a dry, cool place. Avoid extremes of temperature. |
| Exposure Controls / Personal Protection | |
| Control Parameters | UK HSE EH40 Dust: 10mg/m3 8-hour TWA total inhalable dust 4 mg/m3 8-hour TWA respirable dust |
| Engineering Measure | Ensure adequate ventilation, especially in confined areas. Provide appropriate exhaust ventilation at places where dust is formed. |
| Personal Protection Equipment | |
| Respiratory Protection | If dust is created: Effective dust mask (disposable, EN149 FFP2S ). Half or full-face mask with particle filter type P2 (European Standard). |
| Hand Protection | PVC or other plastic material gloves / Rubber gloves. |
| Eye Protection | Goggles. |
| Skin & Body Protection | Lightweight protective clothing. |
