The skin acts as the body’s first defense mechanism, playing a critical role in protecting against chemical hazards. There are over 50 types of chemical burns, primarily caused by inorganic acids and alkalis. In addition to accidents or improper operations, most chemical burns occur due to inadequate personal protective measures. Moreover, many organic solvents—such as carbon tetrachloride, aniline, nitrobenzene, trichloroethylene, leaded gasoline, and organic phosphorus compounds—can be absorbed through the skin, leading to systemic poisoning even without visible burns.
Wearing appropriate chemical protective clothing is essential for anyone working in environments where chemical exposure is possible. In hot conditions, such as during summer or in high-temperature work areas, the dilation of skin capillaries can increase absorption rates, raising the risk of harm. Many chemicals, including dyes, rubber additives, and pharmaceutical intermediates, can cause contact dermatitis or allergic reactions. Therefore, it's crucial for workers to understand that "skin can be a source of illness." Proper protective clothing helps block harmful substances like acids, alkalis, and solvents, preventing direct skin contact. Even in closed systems like chemical plants, workers who handle materials directly—such as feeders and maintenance personnel—should wear protective gear to reduce the risk of accidents and ensure their safety.
Choosing the right protective clothing involves considering several factors. There are two main types: disposable and reusable. Disposable suits are ideal for short-term use and eliminate the need for cleaning, offering better hygiene and convenience. Reusable options, while cost-effective in the long run, require careful cleaning and maintenance, which can be time-consuming and expensive. Additionally, reusing contaminated suits may lead to bacterial growth, especially in hot and humid environments, making them less safe over time. For these reasons, many developed countries have shifted toward using limited-use protective clothing, which provides reliable protection based on standardized test data and ensures safety after each use.
When selecting protective clothing, the primary concern should be its ability to shield the wearer from specific hazardous substances. The material must be suitable for the chemicals involved, and manufacturers should provide penetration data to help determine safe wearing times. Other factors include the durability, fit, and comfort of the clothing. A well-fitted suit prevents snagging or tearing, ensuring both safety and comfort. While some protective gear offers excellent comfort, it may lack sufficient protection, and vice versa. Finding a balance between protection, durability, and comfort is key.
Chemical protective clothing works by blocking or slowing the penetration of harmful substances. Penetration occurs when chemicals move through fabric gaps, while permeation involves chemical absorption at the outer layer and diffusion through the material. Protection is measured by the time it takes for a chemical to penetrate and the rate at which it does so. Standards like the European penetration threshold (1.0 μg/cm²/min) help determine safe usage periods. However, repeated use makes it difficult to track exposure, and testing often destroys the garment, making it unsuitable for further use. This is why limited-use protective clothing is increasingly preferred, offering reliable performance and disposal after use.
Ultimately, the decision to use protective clothing should prioritize health and safety over cost. However, it’s also important to assess the actual risks involved. Factors such as the type of chemicals, their concentration, and the manner of exposure (e.g., continuous or accidental) should guide the selection of appropriate protective gear. A comprehensive approach that considers protection, comfort, and cost will ensure the best outcomes for workers in hazardous environments.
