OCCUPATIONAL DERMATITIS
What is it?– Inflammation of the skin– Results from exposure to irritants in the work
environment– May be slight reddening of the skin with mild
itching– Rash– Small eruptions with intense itching
What causes it?

• CHEMICAL– Most frequent cause of dermatitis– Acts as primary skin irritant– Differs in two respects:
• Reaction Time• Mode of Action
– Mists, vapors, diluted or full strength
CAUSES OF SKIN PROBLEMS
• MECHANICAL– Friction– Pressure– Results in abrasions,
wounds, bruises– Introduces foreign bodies
into skin• Examples: Falling on Non-
Skid, Air Nozzle
• BIOLOGICAL AGENTS– Bacteria, viruses, fungi,
and insects– Complicates dermatitis
• Examples: Bee stings, Athlete’s foot
– Not all skin reacts in the same way or to the same degree to causes

FACTORS INFLUENCING SKIN REACTION
TYPE OF SKIN Pigmentation Dryness Hairiness
GENDER Women have more sensitive, less oily skin than
men
AGE Affects younger personnel more

FACTORS INFLUENCING SKIN REACTION
TEMPERATURE EXTREMES More prevalent in warm weather Risk of direct contact is greater due to less
clothing worn Excessive perspiration - skin is more
vulnerable Low winter temps cause dry, chapped skin
causing cracks

FACTORS INFLUENCING SKIN REACTION
EXCESSIVE OILINESS/DRYNESS Naturally oil skins are less likely to incur dermatitis
when working with fat solvents More susceptible to substances that remove oil Dry skin cracks easily, especially around alkalis
and solvents Cracked skin makes skin subject to infections
LACK OF CLEANLINESS ALLERGIES
