At 70—140°C, peroxide is vaporised. Peroxide vapor has been reported to rapidly inactivate pathogenic bacteria, yeast, and bacterial spores in very low concentrations (133). Experiments using peroxide vapor for space decontamination of rooms and biologic safety cabinets hold promise (134). The use of peroxide vapor and a plasma generated by radio frequency energy releasing free radicals, ions, excited atoms, and excited molecules in a sterilising chamber has been patented (135). 

Decontaminants. Area decontamination is not required as CS has a short duration, of effectiveness. Personnel exposed to CS may shower as necessary however, when CS dust or particles are on the skin, showering should be delayed for 6 hours to prevent stinging and reddening of the skin. Individuals affected by CS should move to fresh air, face the wind, and remain well spaced and should not rub their eyes. To remove accidental gross contamination, personnel should remove clothing and immediately flush body with copious amts of water to remove most of the agent apply 5% Na bisulfite soln to remove remainder (except in or around eyes) and then rinse body... 

Decontamination None required in the field. Caustic soda or chlorine used for gross contamination in enclosed spaces.

Canyon structure for containment of process equipment, which would be installed and replaced remotely by overhead cranes. This arrangement is most cost effective in that it provides for maximum use of building space since there is no need for space between process equipment Failed equipment can be replaced in less than one day and is then moved to separate maintenance shops within the canyon structure for decontamination and repair. 

Hold a briefing for entry personnel and support crew. Ensure that all staff on scene understand emergency signals, preplanned escape routes, locations of Hot/Warm/ Cold zones, operational hazards at this site, the evacuation system, the buddy system, the need for appropriate personal protective equipment (PPE) the potential need to decontaminate rescuers and their equipment, and contaminated persons location of rehabilitation area, possible air space closure over incident site, etc.

Therefore, the energetic materials could interact with water molecules or with exchangeable cations in the interlayer space of mineral. These interactions are considered as one of many possibilities for the remediation of highly contaminated soils by energetic materials [31]. This is the reason why the understanding of phenomena of hydration of clay minerals is the crucial aspect, which could help to find a possible way of decontamination.

Drawbacks of the RTP ports are that they cannot be hooked into the isolator clean in place (CIP) system so, they must always be considered dirty until an adequate cleaning procedure is developed. There are also size limitations to the RTP ports and their corresponding containers. Once a certain size port is selected for the isolator, this is the only diameter container that can be used, unless the isolator port is modified. The port also requires an additional penetration of the isolator wall and serves as another potential point for air leaks. In addition, the RTP containers are not amenable to the transport of flasks into and out of the isolator they require rotation and maneuvering of the RTP container to dock it into the isolator. Unless the port is mounted into the isolator floor, which will take up valuable space, the ability to transport liquids into and out of the isolator is limited to securely closed vials or bottles. The final limitation is the tendency of the seals on the mating surfaces of the RTP ports to become contaminated with potent material during transport operations. Procedures should be put in place to ensure that the mating surfaces of the RTP ports are thoroughly decontaminated as soon as the transport container is undocked from the isolator wall. 

For the pharmaceutical and food industries, surface finish is very important to enable effective cleaning and sterilization or sanitization. Equipment should be specified with a polished internal finish, possibly with electropolishing for critical applications, and designed with a minimum of crevices or dead spaces where dirt can collect. Welds must be finished to the same standard as the plates and ground flush with the internal surface and must be pinhole and crevice free. External surface finish may also be important for visual reasons and to enable cleaning down for surface decontamination in clean room locations. 

It is important to distinguish between radiation and radioactive contamination. Radiation is energy emitted by atoms that are unstable. Radiation travels through space to some extent—some kinds of radiation can only travel a few millimeters, whereas other types can travel for many meters. Radioactive contamination is the presence of radiation-emitting substances (radioactive materials or RAM) in a place where it is not desired. A patient may be contaminated with radioactive materials, but that patient will not be inherently radioactive and can be decontaminated. Radioactive materials, by comparison, are inherently radioactive—it is a physical property of that material in the same manner as mass or size—and they remain radioactive until they decay to stability.
