- Health Hazards - Eye irritation Contact with eyes may cause redness and irritation. - Skin irritation Prolonged or repeated exposure may lead to mild irritation. - Inhalation Dust may cause respiratory irritation.

- Environmental Hazards While the substance is not classified as dangerous to the environment, it is advisable to prevent large quantities from entering water bodies to avoid disruption of aquatic life.

4. Composition/Information on Ingredients

The primary ingredient in this substance is sodium dihydrogen phosphate dihydrate. It is comprised of the following

- Sodium (Na) - Phosphorus (P) - Oxygen (O) - Water (H2O)

In its dihydrate form, it contains two molecules of water, which contribute to its properties as a hydrophilic compound.

5. First-Aid Measures

In case of exposure, the following first-aid measures should be taken

- Inhalation Move the individual to fresh air. Seek medical attention if symptoms persist. - Skin Contact Wash contaminated skin with soap and water. Remove contaminated clothing. Seek medical help if irritation occurs. - Eye Contact Flush eyes with plenty of water for at least 15 minutes while holding the eyelids open. Seek medical attention if irritation persists. - Ingestion Rinse mouth with water. Do not induce vomiting. Seek medical assistance immediately.

6. Fire-Fighting Measures

Although sodium dihydrogen phosphate dihydrate is not flammable, in case of a fire, appropriate extinguishing media should be used, such as water spray, dry chemical powder, or foam. Firefighters should wear protective gear, including self-contained breathing apparatus (SCBA).

7. Handling and Storage

- Handling Always wear appropriate PPE (Personal Protective Equipment) such as gloves, goggles, and dust masks when handling the compound. Work in a well-ventilated area to minimize inhalation risk. - Storage Store in a tightly closed container in a cool, dry place away from incompatible substances such as strong acids and bases.

8. Exposure Controls/Personal Protection
