Chromic Acid and Its Salts Work
Chromic Acid and Its Salts Work
Health Hazards
Acute:
Chromic acid can affect human health through inhalation, ingestion, or contact with the eyes or skin. Skin exposure to chromic acid may lead to skin ulcers.
Chromic acid mist and dust can severely irritate the nose, throat, bronchi, lungs, and skin. There have been cases where chromic acid injuries led to fatal nephritis.
Workers exposed to chromic acid concentrations of 0.11 to 0.15 mg/m³ have experienced nasal septum ulcers, irritation of the pharynx, conjunctiva, and asthmatic bronchitis.
Workers exposed to high concentrations of chromic acid mist for 4 days experienced severe frontal headaches, wheezing, breathing difficulties, coughing, and pain when inhaling; symptoms persisted for 6 months with chest pain and coughing during inhalation.
Exposure to air concentrations of 0.18 to 1.4 mg/m³ for 2 weeks caused moderate irritation of the nasal septum, with nasal septum ulcers appearing after 4 weeks and perforation after 8 weeks.
A worker exposed to undetected levels of chromic acid mist for 5 years developed jaundice and chromium salts in excretions.
Exposure to chromic acid can cause tooth erosion and discoloration. Ingestion may cause vomiting and gastrointestinal damage.
Blood changes include an increase in white blood cells, a decrease in white blood cells, an increase in monocytes, and an increase in eosinophils.
Eye exposure to chromic acid may cause severe corneal damage.
Chronic:
Repeated or prolonged exposure to chromic acid dust or mist may cause nasal septum ulcers and perforation. Respiratory irritation may resemble asthma, and liver damage or jaundice has also been reported.
Repeated or prolonged skin exposure may cause rashes and allergic dermatitis.
Exposure to chromate dust increases the risk of bronchial cancer, with hexavalent chromium having a particularly high potential for causing lung cancer. Workers in chromate factories have a higher incidence of lung cancer.
Suggestions:
Level 1 Management: No specific regulations.
Level 2-4 Management:
Consider health conditions unsuitable for this type of work, such as respiratory diseases, contact dermatitis, and health protection for pregnant workers.
