Flame-resistant (FR) coveralls are an essential component of personal protective equipment (PPE) designed to safeguard workers from the risks associated with fire and heat. These coveralls are widely used in industries such as oil and gas, electrical, chemical, manufacturing, and construction, where employees face the constant threat of flash fires, electrical arcs, and intense heat. However, to ensure that FR coveralls provide optimal protection, they must meet specific standards and certifications. Understanding these standards and certifications is crucial for both employers and workers to ensure that they are using the correct protective gear to meet safety requirements.
