Occupational Skin Disease: Types of Occupational Exposure and Treatment Methods

In a previous article, Occupational Skin Disease: Insights by Dr. Breslavets, the fundamentals of occupational skin disease were introduced, including its definition, prevalence, and overall clinical significance. Building on that foundation, the present discussion explores occupational skin disease in greater depth, with a particular focus on the main types of occupational exposure, along with general principles of prevention and treatment.

Occupational skin disease is one of the most commonly occurring work-related medical conditions. By definition, a skin disorder is classified as occupational when a clear causal relationship exists between the individual's occupation and the development of the skin condition. Occupational skin diseases are broadly categorized into three main groups: irritant contact dermatitis, allergic contact dermatitis, and other occupationally related skin diseases. The majority of reported cases fall within one of the contact dermatitis categories.

Occupational exposures contributing to skin disease are generally classified as chemical, biological, or physical. Chemical exposure is among the most frequent causes and includes contact with substances such as hair dyes, rubber additives, preservatives, acrylates, and epoxy resins, all of which may induce allergic contact dermatitis. Certain chemicals, including tar and arsenic, are associated with an increased risk of skin cancer, while phenols and catechols may lead to skin depigmentation. Prolonged exposure to cement, particularly under occlusive conditions, can result in chemical burns.

Biological exposure may occur through contact with animals or humans carrying infectious agents. Examples include orf transmitted from sheep and goats, tinea corporis acquired from pigs, cats, or dogs, and milker's nodules transmitted from cattle. Contact with infected or infested individuals can result in fungal infections such as tinea corporis or infestations including scabies and head lice.

Physical exposure involves mechanical or environmental injury to the skin. Repeated trauma may lead to blisters, cuts, calluses, and blood clots. Some cases of basal cell carcinoma have been reported to arise within scars from previous thermal injuries. Direct exposure to heat can cause burns, while chronic contact with rough surfaces, fibres, or particulates may trigger irritant contact dermatitis.

Prevention of occupational skin disease begins with identifying the underlying cause. Both employers and workers play an essential role in recognizing workplace hazards, a process that should be ongoing and reflect changes in work practices, materials, and safety knowledge. Evaluating exposure levels and assessing the degree of risk posed by each hazard are critical steps, as is maintaining accurate records of workplace accidents, incidents, and diagnosed occupational diseases.

Where possible, direct contact between the skin and hazardous substances should be eliminated or enclosed. This may be achieved through automation or the use of encapsulated equipment, such as enclosed food mixers or industrial dishwashers. When elimination is not feasible, exposure should be minimized by rotating tasks, limiting the duration of exposure, and providing appropriate personal protective equipment, including gloves, face shields, and protective clothing. Worker education regarding occupational risks and preventive strategies is also essential.

Once exposure has been minimized, regular monitoring of workers' skin health is recommended, particularly for those with ongoing exposure to known hazards. If occupational skin disease develops, treatment should be determined by a dermatologist and tailored to the individual's condition. Common treatment approaches may include topical or oral corticosteroids, emollients, and antibiotics when secondary infection is present. Early recognition and appropriate management are key to preventing chronic disease and long-term complications.
