The coveralls should also be highly visible, so that they can be seen in areas where there is moving traffic. Coveralls that are designed for different purposes should adhere to the different uses. In other words, the standards associated with coveralls would differ depending on the purpose that they are designed for. For example, the fire retardant coveralls should be able to discourage flames and heat.
