Chemical suits

Wear rubber gloves, chemical goggles and, depending upon scale, a rubber apron or full chemical suit. 

Wear appropriate chemical cartridge respirator depending on the amount of exposure rescue personnel should be equipped with self-contained breathing apparatus have available and use as appropriate mbber suits, full-body chemical suits, safety shoes, safety shower, and eyewash fountain.

Ascorbate is a major antioxidant, protecting cells and tissues from damage by free radicals, peroxides, and other metabolites of O2.P It is chemically suited to react with many biologically important radicals and is present in high enough concentrations to be effective. It probably functions in cooperation with glutathione (Box 11-B), a-tocopherol (Fig. 15-24), and lipoic acid. Ascorbate can react with radicals in one-election transfer reactions to give the monodehy-droascorbate radical ... 

Emergency responders should have a thorough knowledge of corrosive materials. After flammable liquids and gases, corrosives are the most frequently encountered hazardous material. Responders should have proper chemical protective equipment and SCBA to deal safely with corrosive materials. Firelighter turnouts will not provide protection from corrosives. The most common exposures are contact with the hands and feet, and inhalation of the vapors. Make sure that the chemical suits chosen for use are compatible with the corrosive material. No suit will protect you from chemicals indefinitely they all have breakthrough times. Make sure personnel are rotated to avoid prolonged exposure, and make sure they do not contact the material unless absolutely necessary. Safety should be your primary concern. 

However, because many old shells—whether unexploded on a range or buried—have rusted, they may be difficult to assess as paint and markings are gone. Some ranges and many burial sites may have both chemical and high explosive ordnance. Wearing a chemical suit under Kevlar may be the best practice. Where only explosive ordnance is likely to be encountered, but chemical rounds are still possible, a charcoal-lined suit is a good choice under the Kevlar. 

For investigative and corrective purposes it may be necessary to determine whether an environment has become dangerous because of a chemical leak. An air pack and chemical suit might be required in this instance.
