Exposure Controls/Personal Protection

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.
