There are many professions that require employees and workers to obtain various pieces of safety clothing such as protective shoes and hats and flame resistant clothing, but it's not only firefighters who need to be protected against the dangers of fire or contact with possible chemical spills. City workers or independent business employees who many work in an electrical field would likely need to have access to fire resistant items since dealing with sparks and potential fires is not uncommon in jobs where the maintenance of aging buildings and electrical systems is common and just a daily part of the profession.
