Occupational contact dermatitis due to chromium

Due to the physical and chemical properties and advantages of chromium and its compounds, chromium is increasingly used, and consequently, occupational hazards related to chromium are also rising.

Researching chromium contamination and its harmful effects is essential because even small amounts of chromium compounds can pose health risks to workers, especially causing occupational contact dermatitis due to chromium.

1. What is occupational contact dermatitis caused by chromium?

Occupational contact dermatitis caused by chromium is a skin inflammation resulting from direct exposure to chromium, especially chromium compounds (Cr VI) during work activities.

2. Occupations at risk of occupational contact dermatitis caused by chromium

Common occupations and exposure sources:

• Cement production and use.
• Chrome plating and electroplating.
• Battery manufacturing.
• Metallurgy.
• Production of candles, wax, dyes, detergents, explosives, fireworks, matches, adhesives.
• Ceramics, chromium salts, pigments, enamel, glass, zinc plates, rubber, refractory bricks, soap, aluminum alloys.
• Other occupations with exposure to Cr VI.

3. Mechanism and causes of occupational contact dermatitis caused by chromium

The mechanism of occupational contact dermatitis caused by chromium involves the effects of chromium compounds through three pathways: respiratory, digestive, and dermal.

When exposed to chromium compounds, they usually enter the body through the skin. Cr(VI) can be absorbed through the skin and converted into Cr(III), a less toxic form but still capable of causing skin irritation. Prolonged exposure to Cr(VI) can accumulate in the skin and trigger immune system reactions, leading to allergic responses and dermatitis.

Additionally, factors such as exposure duration, dosage, and the chemical form of chromium can influence the disease mechanism. Workers in painting, plating, chemical manufacturing, and steel production are at high risk of occupational contact dermatitis caused by chromium.

Discover the Chromium Occupational Contact Dermatitis Risk Assessment Tool, providing detailed risk evaluations and safety prevention recommendations for workers and managers. With multidimensional databases and advanced algorithms, this tool is a reliable resource for healthcare and occupational safety professionals, aiming to protect workers from chromium-related dermatitis and maintain a safe work environment.

4. Symptoms and effects of occupational contact dermatitis caused by chromium

• Allergic contact dermatitis:
  • Red patches, swelling at the exposed skin area, potentially progressing to vesicles, epidermal erosion, and oozing.
  • Functional symptom: itching.
  • First symptoms appear a few weeks after initial exposure to the allergen.
  • Subsequent exposure (even small amounts) can trigger allergic reactions.
• Irritant contact dermatitis: redness, scaling, cracks, and burning sensation at the exposed skin area, commonly on hands and feet.
• Chromium-induced ulcers: deep, well-defined round ulcers, often on nails, finger joints, between fingers, or dorsal hand; these are usually painless, dry, and heal poorly, leaving scars.
• Painless nasal septum perforation with foul-smelling nasal discharge, starting 1.5–2cm from the anterior-inferior septum and extending posteriorly.

5. Protective equipment to prevent occupational contact dermatitis caused by chromium

Protective equipment is essential to prevent occupational contact dermatitis caused by chromium. It helps protect the skin and minimize direct exposure to chromium compounds. Essential protective gear includes:

• Chemical-resistant gloves, such as nitrile or neoprene, to reduce direct exposure to chromium compounds.
• Chemical-resistant clothing, such as polyester or nylon, to minimize direct contact with chromium compounds.
• Protective goggles to shield eyes from toxic fumes and dust.
• Respiratory masks to protect against inhalation of toxic fumes.
• Safety shoes to protect feet from direct contact with chromium and other chemicals.

Using appropriate protective gear is a key method to reduce the risk of chromium-related occupational contact dermatitis in industrial settings.

6. Compensation for workers with occupational contact dermatitis caused by chromium

In Vietnam, workers with chromium-related occupational contact dermatitis can receive compensation under labor law and social insurance regulations:

• According to the Social Insurance Law, workers suffering from occupational diseases, including chromium dermatitis, are entitled to social insurance benefits, covering wage support, medical costs, and other treatment and rehabilitation expenses.
• If the disease is caused by unsafe working conditions, workers have the right to request improvements and financial compensation from the employer.

Workers must meet insurance contribution requirements and provide evidence linking the disease to workplace exposure to receive compensation.

7. Treatment of occupational contact dermatitis caused by chromium

Treatment depends on severity and patient health, but common methods include:

• Preventing spread and recurrence by using appropriate skin protection to minimize chromium exposure.
• Anti-inflammatory creams and pain relief medication as prescribed to reduce pain, itching, inflammation, and swelling.
• Other treatments under the care of medical specialists at healthcare centers.

Patients should also practice proper skin care, use non-irritating products, avoid contact with skin irritants, and maintain good nutrition to strengthen immunity.

8. Prevention of occupational contact dermatitis caused by chromium

Preventive measures include:

• Wear full protective equipment, including goggles, masks, gloves, and protective clothing, when working in chromium-containing environments.
• Follow training and safety procedures for handling chromium.
• Consult a doctor immediately if skin lesions or other symptoms appear.
• Undergo regular health check-ups to detect early signs of chromium-related disease.
