Epoxy resins, widely used in adhesives, coatings, and composite materials, can emit fumes that are potentially hazardous to human health, particularly during the curing process. Exposure to these fumes may lead to irritation of the eyes, skin, and respiratory system. Prolonged or high-level exposure can exacerbate asthma and cause sensitization, leading to allergic reactions. It is paramount to use epoxy in well-ventilated areas, wear appropriate personal protective equipment (PPE), such as gloves and masks, and closely follow the manufacturer's safety guidelines to mitigate these risks. Employing proper safety measures can significantly reduce the hazards associated with epoxy fumes, ensuring a safer environment for workers and users alike.

E171. also called titanium dioxide. has been prohibited in Europe due to its potential health hazards. Its safety was reviewed by the European Food Safety Authority EFSA and it was deemed an unsafe food additive. primarily because of worries about its nanoparticle version and potential link to cancer. Research has indicated that E171's nanoparticles can harm cells and DNA and increase the risk of cancer. Therefore. the European Commission has opted to outlaw its utilization in food starting in 2022.

Plastic blow molding is a manufacturing process used to create hollow plastic parts. One advantage is cost-efficiency for high volume production, as it enables rapid production of parts with uniform wall thickness and excellent surface finish. It’s also versatile, allowing for the creation of complex shapes. However, the initial setup and tooling costs can be high, making it less economical for small production runs. Additionally, material choice is limited to those that can be blow molded, restricting design flexibility. While it offers strength and lightweight benefits, environmental concerns due to plastic use and the difficulty in recycling some molded products are notable disadvantages.
