The Correct Answer and Explanation is :
Sodium hypochlorite (NaOCl) is a widely used chemical compound, commonly found in household bleach solutions with concentrations ranging from 4% to 6%. It is a clear, slightly yellow or green liquid with a strong chlorine odor. citeturn0search9
Physical State:
Sodium hypochlorite is typically encountered as a liquid at room temperature.
Route of Exposure & Symptoms:
Exposure to sodium hypochlorite can occur through various routes:
- Eyes: Contact can cause severe irritation, burns, and potential eye damage.
- Skin: Exposure may lead to severe irritation, burns, and possible dermatitis.
- Inhalation: Inhalation of vapors can irritate the respiratory tract, leading to coughing, shortness of breath, and, in severe cases, pulmonary edema.
- Ingestion: Swallowing can result in severe digestive tract burns, abdominal pain, vomiting, and potential systemic effects.
Protective Equipment:
To mitigate exposure risks, the following protective equipment is recommended:
- Eyes: Safety goggles or face shields.
- Skin: Chemical-resistant gloves and protective clothing.
- Respiratory: Use in well-ventilated areas; if ventilation is inadequate, appropriate respiratory protection may be necessary.
First Aid Procedures:
In case of exposure:
- Eyes: Immediately flush with water for at least 15 minutes and seek medical attention.
- Skin: Wash with plenty of water for at least 15 minutes; remove contaminated clothing and seek medical attention.
- Inhalation: Move to fresh air immediately; if breathing is difficult, administer oxygen and seek medical attention.
- Ingestion: Do not induce vomiting; rinse mouth with water and seek medical attention immediately.
Firefighting Measures:
Sodium hypochlorite is not combustible but is a strong oxidizer. In the event of a fire:
- Extinguishing Media: Use water spray, dry chemical, carbon dioxide, or appropriate foam.
- Special Hazards: Decomposition can produce toxic gases, including chlorine.
- Protective Equipment: Wear a self-contained breathing apparatus and full protective clothing.
Chemical Reactivity:
Sodium hypochlorite reacts violently with strong acids, ammonia compounds, and organic materials, potentially releasing toxic gases like chlorine. It is incompatible with metals such as copper, nickel, cobalt, and iron. citeturn0search9
Safe Storage:
Store in a cool, well-ventilated area away from incompatible materials. Use containers made of materials resistant to corrosion, such as polypropylene. Keep containers tightly closed and upright to prevent leaks.
Safe Disposal:
Dispose of sodium hypochlorite solutions in accordance with local, regional, and national regulations. Neutralization with sodium bisulfite followed by disposal as hazardous waste may be necessary.
Environmental Ecotoxicity:
Sodium hypochlorite is very toxic to aquatic life and can cause long-lasting effects in the environment. Avoid release to the environment and ensure proper containment and disposal.
Spill Cleanup Procedures:
In the event of a spill:
- Personal Protection: Wear appropriate protective equipment.
- Containment: Prevent further leakage or spillage if safe to do so.
- Cleanup: Absorb the spill using an absorbent, non-combustible material such as earth, sand, or vermiculite.
- Disposal: Dispose of the collected material in accordance with local regulations.
