What is workplace dermatitis?
Work-related contact dermatitis is a skin disease caused by work. It is often called eczema and develops when the skin is damaged. This leads to redness, itching, swelling, blistering, flaking and cracking. The most susceptible parts of the body are the hands, followed by the forearms and face.
There are two main types of work-related contact dermatitis, irritant contact dermatitis and allergic contact dermatitis.

No antecedent immunologic sensitization is required. Some primary skin irritants are also allergens. Only about 20% of all occupational contact dermatitis results form sensitization, while about 80% is attributable to primary irritants.
What is a distinguishing feature of Sensitising dermatitis?
Skin sensitisers may cause symptoms of dryness, redness and itching of the skin. The skin may become swollen, cracked, scaly and thickened and blisters may develop.
