| [Fire Fighting] Extinguish fire using regular foam, water fog, carbon dioxide, sand. Wear a self-contained breathing apparatus with a full facepiece operated in the positive pressure demand mode with appropriate turn-out gear and chemical resistant personal protective equipment. | |
| [Ingestion] First aid is not normally required. If symptoms develop, seek medical attention. | |
| [Inhalation] If symptoms develop, move individual away from exposure and into fresh air. If symptoms persist, seek medical attention. If breathing is difficult, administer oxygen. Keep person warm and quiet; seek immediate medical attention. | |
| [Skin] First aid is not normally required. However, it is recommended that exposed areas be cleaned by washing with soap and water. | |
| [Eyes] If symptoms develop, immediately move individual away from exposure and into fresh air. Flush eyes gently with water for at least 15 minutes while holding eyelids apart; seek immediate medical attention. | |
| [Storage] Keep tightly closed in a cool place in a tightly closed container. | |
| [Handling] Containers of this material may be hazardous when emptied. Since emptied containers retain product residues (vapor, liquid, and/or solid), all hazard precautions given in the data sheet must be observed. | |
| [Inhalation] This material is a dust or may produce dust. Breathing small amounts of this material is not likely to be harmful. | |
| [Skin] Unlikely to cause skin irritation or injury. | |
| [Eyes] Dust can cause eye irritation. Symptoms include stinging, tearing, redness, and swelling of eyes. | |
| [Ingestion] Swallowing this material is not likely to be harmful. | |
| [Personal Protection] Chemical splash goggles in compliance with OSHA regulations are advised; however, OSHA regulations also permit other type safety glasses. Whre chemical resistant gloves. To prevent repeated or prolonged skin contact, wear impervious clothing and boots. | |
| [Respirators] 3M Dust respirator No. 8710 or 9900 is recommended or a NIOSH/MSHA jointly approved dust respirator. | |
| [Exposure Effects] Chronic ingestion of calcium carbonate may cause irritability, lethargy, stupor, and coma, depending on the amount and duration of ingestion. These symptoms are secondary to hypercalcemia, alkalosis, and renal impairment. Chronic ingestion of calcium carbonate in doses 4 to 60 g/day for 2 to 30 days has resulted in these symptoms; however, at doses less than 10 g/day, pre-existing factors such as renal dysfunction, concurrent thiazide therapy, volume depletion, or hyperparathyroidism were usually present in patients developing these sequelae. | |
