Which of the following types of clothing should not be worn while performing electrical work?

When performing electrical work, it is essential to choose clothing that minimizes the risk of fire and provides adequate protection. Polyester, a synthetic material, tends to melt when exposed to high temperatures or flames, which can lead to severe burns if an electrical accident occurs. This is why it is advised to avoid wearing polyester or other similar synthetic fabrics while working with electricity.

In contrast, cotton, wool, and denim are generally safer choices for electrical work. Cotton is breathable and less likely to ignite or melt, while wool has some natural fire-resistant properties. Denim provides adequate protection and is durable, making it suitable for industrial environments. Choosing the right type of clothing is critical for ensuring safety while performing electrical tasks, highlighting the importance of fabric choice in preventing accidents and injuries.
