Section 5 - FIRE FIGHTING MEASURES
General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use water spray to keep fire-exposed containers cool. This material in sufficient quantity and reduced particle size is capable of creating a dust explosion. Runoff from fire control or dilution water may cause pollution.
Extinguishing Media:
For small fires, use water spray, dry chemical, carbon dioxide or chemical foam.

---

Section 6 - ACCIDENTAL RELEASE MEASURES
General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, observing precautions in the Protective Equipment section. Avoid generating dusty conditions.
Provide ventilation.

---

Section 7 - HANDLING and STORAGE
Handling:
Use with adequate ventilation. Minimize dust generation and accumulation. Avoid contact with skin and eyes. Avoid ingestion and inhalation.
Storage:
Store in a cool, dry place. Keep from contact with oxidizing materials.

制备方法与用途

用途

L-乳酸钙属于天然活性离子钙，已获得美国食品药品管理局（FDA）批准作为食品添加剂使用。它因含有高浓度的钙、良好的溶解度、较高的吸收率、极高的安全性和合理的价格而备受重视。

化学性质

L-乳酸钙是一种白色无味粉末或颗粒，具有微风化性与抗氧化性。该物质易溶于水但不溶于乙醇，在120℃下会失去全部结晶水，并能增强活性和稳定pH值。

生产方法

L-乳酸钙以淀粉为原料，通过天然发酵制成。
