Protective overalls, coveralls and suits protect against workplace hazards and rainy or cold weather. They include welding and heat-resistant overalls, beekeeper overalls, chemical-resistant coveralls and rain suits and overalls. Welding and heat-resistant overalls protect welders from high heat, flames and sparks. Beekeeper overalls protect against bee stings, while chemical-resistant coveralls resist chemicals such as acid, ketones and esters. Rain suits and rain overalls seal out water to keep workers dry in wet conditions. They are often lined with fleece to keep workers warm.
