CHEMICAL PROTECTION




                                               IMPORTANCE OF CHEMICAL WORKWEARS

                                               Chemical suits are designed to protect the entire body from exposure to harmful                                        CHEMICAL PROTECTION
                                               and possibly fatal chemicals. Without these suits, it would be impossible to contain
                                               dangerous chemical spills or explosions where hazardous chemical waste or other
                                               potentially fatal chemicals must be cleared away and disposed of properly. These
                                               suits protect the wearer so that clean up is done without risk.
