In a factory setting, all the employees should be provided with coveralls. Then they will be able to stay protected from hot particles, sparks, direct flame, molten metal splashes, radiant heat and many other hazardous substances. 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. On the other hand, quilted coveralls should be in a position to keep cold temperatures away from penetrating through the fabric.
