Final answer:
Granular CaCl₂ is not considered a significant inhalation hazard, but precautions such as the use of dust masks or respirators and proper ventilation are recommended to minimize any potential risks.
Step-by-step explanation:
No, granular material of CaCl₂ does not pose a significant inhalation hazard under normal handling conditions. However, as with any chemical substance, it is always wise to handle it with care, and it's advisable to wear appropriate personal protective equipment such as a dust mask or respirator to prevent irritation or discomfort when working with large quantities or in an enclosed space where dust particles may be present in the air.
If large amounts of dust are inhaled, it can cause irritation of the nose, throat, and lungs. The composition of calcium chloride is such that it is hygroscopic, meaning it can readily absorb water from the air and this attribute can help reduce the amount of airborne particles, mitigating potential inhalation issues.
As with all handling of chemicals, maintaining adequate ventilation and using controls to reduce dust exposure, such as fume hoods or dust collection systems, are important safety measures. In cases of significant exposure or symptoms following inhalation, seek immediate medical attention.
