- Chest tightness and shortness of breath
- Pulmonary edema (fluid buildup in the lungs)
- Pneumonia
Ingestion
Ingesting lithium can be extremely dangerous, even in small quantities. Lithium is highly toxic when ingested, and can cause severe gastrointestinal symptoms, including:
- Severe vomiting and diarrhea
- Abdominal pain and cramps
- Seizures and tremors
- Coma or even death
Handling Lithium Safely
Given the risks associated with lithium exposure, it’s essential to handle it safely. Here are some guidelines to follow:
- Wear protective gear: When handling lithium, wear protective gloves, safety glasses, and a face mask to prevent skin contact and inhalation.
- Use ventilation: Work in a well-ventilated area to prevent inhaling lithium dust or powder.
- Avoid skin contact: Avoid touching lithium with bare hands, and wash your hands thoroughly after handling it.
- Follow proper disposal procedures: Dispose of lithium-containing materials according to local regulations and guidelines.
Regulations And Exposure Limits
Governments and regulatory agencies have established exposure limits to protect workers and the general public from lithium toxicity. In the United States, the Occupational Safety and Health Administration (OSHA) has set the following exposure limits:
- Permissible Exposure Limit (PEL): 0.025 milligrams per cubic meter (mg/m3)
- Short-Term Exposure Limit (STEL): 0.05 mg/m3
Similarly, the National Institute for Occupational Safety and Health (NIOSH) recommends an exposure limit of 0.01 mg/m3.
Conclusion
Lithium, while incredibly useful in many applications, poses significant risks when not handled properly. It’s essential to understand the risks associated with lithium exposure and take necessary precautions to prevent skin contact, inhalation, and ingestion. By following safety guidelines and exposure limits, we can minimize the risks and ensure a safe working environment.
Remember, lithium is not to be taken lightly. Its toxicity can have serious consequences, and it’s our responsibility to handle it with care.
