Irritation from Contact Dermatitis

Irritation from Contact Dermatitis
"""What is contact irritant dermatitis at work?

Skin inflammation that is localized is known as dermatitis. In general, inflammation describes a state in which the body is attempting to respond to a localized tissue injury. Some or all of the following—redness, heat, swelling, and pain—are indicators of inflammation. An irritation brought on by compounds from the workplace that come into direct touch with the skin is known as occupational irritant contact dermatitis. Blisters, scales, or crusts are symptoms of irritating contact dermatitis. These signs don't always show up at the same time or in every instance. This type of dermatitis is localized to the region of touch and is brought on by substances that irritate the skin, such as acids, bases, and solvents that dissolve fat. A different type of contact dermatitis is known as allergic contact dermatitis, which manifests as an allergic reaction to skin contact with an allergen (e.g., poison ivy). Another distinction is that allergic dermatitis can develop in areas of the body that were not in contact with the allergen.

What causes the onset of irritating contact dermatitis?

After either a brief, intense exposure or a repeated, low exposure to a material at work, irritating contact dermatitis can occur. According to the circumstances of exposure, irritant contact dermatitis manifests itself in a variety of ways. For instance, blisters appear right away after unintentional contact with a potent irritant. Redness of the skin could be the only reaction to contact with a minor irritant. If the irritation persists, however, little blisters or sores develop on the reddish area, and then crusts and scales occur. If there are no consequences, the skin damage normally cures within a few weeks of the exposure ending (e.g., no infections occurred). The ability of a drug to alter certain characteristics of the skin's outer layer, which serves as a protective barrier against hazardous substances, determines how irritating it will be. Some compounds can, among other things, deplete moisture and skin oils from the skin's outer layer. As a result, the skin no longer serves as a barrier as effectively and irritant penetration is increased. Dryness, cracking, and whitening of the skin are also caused by the removal of fat or fat-like substances from the skin. The irritating substance must penetrate the skin's outer layer in order to cause damage. The material then contacts cells and tissues after infiltration. Additionally, the drug interacts with some endogenous (naturally occurring) molecules found in cells and tissues. These responses result in skin damage. An acute localized inflammation is the body's initial response to injury. The tissues and cells attempt to repair the harm while also preparing a protective reaction to flush out the foreign object that caused the harm. An individual may experience discomfort, warmth, redness, and swelling in the irritated area when the body is in its defensive response phase. There won't be any apparent signs of minor skin injury, such as thickening of the inner layer of the skin. When the damage is severe, though, the skin begins to chap, scale, and blister. Also, some skin cells degenerate. An irritating reaction typically appears within a few hours of exposure and peaks twenty-four hours later.

What elements affect irritating contact dermatitis?

The chemical makeup of the material (such as whether it is an acid, an alkali, or a salt), the quantity and concentration of chemical coming into contact with the skin, and the duration and frequency of exposure are all factors that might cause irritation. Individual worker-specific factors are also significant. The range of responses seen in different people when exposed to the same irritant is influenced by hereditary variables. Another thing to keep in mind is the area of the body that is exposed to an irritant. Various parts of the body have different levels of substance absorption. Some compounds, for instance, permeate the face and upper back faster than the arms. Environmental aspects are very important. For instance, hot, muggy workplaces make people perspire. Some forms of industrial chemical powders that may come into contact with the skin can be dissolved by sweat. This increases their toxic or irritant effects of the chemicals because solutions penetrate the skin more readily than solids. On the other hand, sweating may also have a protective function because it may dilute or wash out substances. Working where the air humidity is low or where the skin is wet for prolonged and repeated periods can cause chapping of the skin that, in turn, can increase the possibility of irritation. Friction against the skin, occurring while operating grinding machines and other equipment can scrape away the skin, reducing its protective action against irritants. Clothing soaked with irritants is another important factor. Cuts or skin injuries enable irritant substances to penetrate the skin more readily. Table 1 summarizes some factors that contribute to skin irritation. Table 1 Factors Contributing to the Development of Skin Irritation Related to Substance Related to Person Related to Environment Properties of the chemical Solubility Form: gas, liquid, solid concentration Length and frequency of exposure Region of skin (e.g., hands, arms, face) Health of skin (e.g., cuts, rashes, abrasions) Dryness Sweating Age Genetic background Temperature Humidity, moisture, barometric pressure Friction Contamination

What occupations are at risk?

Table 2 lists some occupations where irritant contact dermatitis has been seen. Table 2 also gives examples of workplace chemicals that can cause irritant contact dermatitis; however, this list is not intended to be comprehensive. New materials and processes can present workers with chemical exposures and risks that they have not experienced previously. Table 2 Irritants Encountered in Various Occupations Condition Irritant Agriculture workers Artificial fertilizers, disinfectants, pesticides, cleaners, gasoline, diesel oil, plants and grains Artists Solvents, clay, plaster Automobile and aircraft industry workers Solvents, cutting oils, paints, hand cleansers Bakers and confectioners Flour, detergents Bartenders Detergents, wet work Bookbinders Solvents, glues Butchers Detergents, meat, waste Cabinet makers, and carpenters Glues, detergents, thinners, solvents, wood preservatives Cleaners Detergents, solvents, wet work Coal miners Dust (coal, stone), wet conditions Construction workers Cement Cooks and caterers Detergents, vegetable juices, wet work Dentists and dental technicians Detergents, hand cleansers, wet work Dry cleaners Solvents Electricians Soldering fluxes Electroplaters Acids, alkalis Floor-layers Solvents Florists and gardeners Manure, artificial fertilizers, pesticides, wet work Hairdressers Permanent wave solutions, shampoos, bleaching agents, wet work Hospital workers Detergents, disinfectants, foods, wet work Homemakers Detergents, cleansers, foods, wet work Jewellers Detergents, solvents Mechanics Oils, greases, gasoline, diesel fuel, cleaners, solvents Metal workers Cutting oils, solvents, hand cleansers Nurses Disinfectants, detergents, wet work Office workers Solvents, (photocopiers, adhesives) Painters Solvents, thinners, wallpaper adhesives, hand cleansers Photography industry workers Solvents, wet work Plastics workers Solvents, acids, styrene, oxidizing agents Printers Solvents Rubber workers Solvents, talc, zinc stearate, uncured rubber Shoemakers Solvents Tannery workers Acids, alkalis, reducing and oxidizing agents, wet work Textile workers Fibres, bleaching agents, solvents Veterinarians and slaughterhouse workers Disinfectants, wet work, animal entrails and secretions

How is it recognized?

Victims of irritant contact dermatitis often consult a doctor or nurse. While some experimental tests can provide an indication of the irritant potential of substances, no single test can reliably identify irritants in specific cases. In the evaluation of occupational irritant contact dermatitis, the best approach is to identify the conditions of exposure by discussing the victim's employment. The information to be gathered includes a detailed list of all chemicals in the individual's working environment; a detailed description of all processes involved in a day's work; and any information about other workers, if any, who have similar skin problems.

How is it treated?

Contact dermatitis may be treated with compresses, creams, ointments and skin cleansers. In general, people should protect their skin from physical trauma, chemical irritation, excessive sunlight, wind, and rapid temperature changes while the dermatitis is active.

How common is it?

The number of cases of irritant contact dermatitis in Canada at this time is not known. In Ontario, Canada, 1,000 compensation claims are reported for contact dermatitis each year. According to some US statistics, skin disorders comprise more than 35 percent of all occupationally related diseases. Among all occupational dermatitis, irritant contact dermatitis accounts for about 80 percent.

What are the preventive measures?

Occupational irritant contact dermatitis can be avoided by the following measures: personal hygiene substitution of a less harmful substance enclosure of the process automation of the work procedures local exhaust ventilation systems good housekeeping education protective clothing barrier creams, skin cleansers convenient washing facilities Personal hygiene, including hand washing, is vitally important in preventing contact dermatitis. Additionally, workers should be aware that excessive exposure to just water alone produces dryness (i.e., removes skin oils) and irritation of the skin. This effect is even greater with the addition of soap and detergents or after exposure to solvents. For skin cleansing, workers should use the mildest soap. For industrial cleaning they should use the mildest detergent. To remove difficult oil and grease stains on hands and arms, workers should use a waterless hand cleanser. If waterless hand cleansers do not remove difficult stains, workers should use abrasive soaps. Waterless hand cleansers and abrasive soaps should be used sparingly and only when necessary. Engineering control methods include the enclosure of processes to separate workers from the harmful substances that they use. Local exhaust systems should be used where toxic substances may escape into the workroom. Nonhazardous substances should replace hazardous substances when possible. Even changing the form of the substance may be beneficial. For example, granules are usually less irritating than a fine powder. Good housekeeping includes proper storage of substances, frequent disposal of waste, prompt removal of spills, and maintenance of the equipment to keep it free of dust, dirt and drippings. Employers should inform workers about the hazards of substances to which they are exposed and how to use them safely. Protective clothing such as aprons and gloves should be properly selected to prevent skin contact. Not all protective clothing resists all substances. Manufacturers' specifications (e.g., kind material, duration of exposure/glove contact time with chemical) should be followed. Barrier creams are used as substitutes for protective clothing, especially when gloves or sleeves cannot be safely used. It is important to remember that they do not provide as much protection as protective clothing. Barrier creams should be properly selected for specific purposes to ensure that they offer protection for the type of chemical being used and that they will not contribute to skin irritation problems. Washrooms, toilets, and showers should be conveniently located and supplied with adequate hot water, disposable towels and soap. Establishing a good program to avoid exposure of the skin to irritant substances is vitally important for eliminating irritant contact dermatitis."""
