Personal protective equipment should protect the wearer in case of accidents. However, it is not a substitute for safe working conditions. The amount of protection necessary depends upon the degree of exposure during a particular task. Protective equipment should not be worn or carried beyond the operating area. After each use, the equipment should be thoroughly washed and tested for DMS contamination before storing.
All personnel should wear full protective clothing and air-supplied respiratory protection when unloading DMS shipping containers, when taking DMS samples, when opening equipment that may contain DMS, and when performing other similarly hazardous duties during which DMS vapor may be inhaled. A standby person equipped with similar protective equipment should be present to assist in an emergency.
Minor incidental contact with DMS is difficult to detect on protective equipment but has caused serious burns following equipment removal. Upon completion of an activity requiring a full protective suit, the person should rinse the suit under a safety shower. The standby person should then assist washing the suit with a brush and mild detergent solution prior to rinsing under the safety shower again. The suit should then be checked with a Dräeger tube for presence of DMS before removing. Change gloves as necessary during protective equipment removal. Rewash suit, hood, and gloves. Don dry protective equipment if re-entry to the DMS area is necessary. Store all protective equipment in the DMS use area.
