NFPA 2001 should be followed for the acceptance testing of clean agent systems. 

Self contained dual agent systems, (foam/water and dry chemical), are provided for manual fire fighting efforts against three dimensional pressure leaks and large diameter pool fires. The design affords fast fire knockdown, extinguishment and sealant against re-flash. A skid

It follows that liquids of high boiling point should not be distilled from drying agent systems which have appreciable vapour pressures. An extreme case of this action is the dehydration of oxalic acid dihydrate by distillation over toluene or over carbon tetrachloride. 

The decomposition temperature should be suitable for the polymer. For example, a decomposition temperature for a blowing agent system for PVC should not be above the maximum possible processing temperature that can be used if significant degradation is not to occur.

Prevention is key in the management of pressure sores. Mild superficial pressure sore infections may be treated with topical antimicrobial agents. Systemic antibiotics are indicated for pressure sores associated with spreading cellulitis, osteomyelitis, or bacteremia.

Clean agent systems can also be used for explosion prevention and suppression where flammable materials are confined. Clean agent fire extinguishing systems are used primarily to protect hazards that are in enclosures or equipment enclosures. Some typical hazards that could be protected by clean agents are ... 

This design permits effective firefighting against three dimensional pressure leaks and large spill fires. The AFFF secures against reflash, as the dry chemical provides for fast knockdown and extinguishment. See NFPA 13 for more information on combined agent systems. 

The enclosure for the clean agent system should be examined for openings and tested to ensure that the agent concentration can be maintained. Currently, the preferred method is using a blower door fan unit and smoke pencil. 

Clean agent systems should be visually inspected semiannually. The inspection should consist of verifying the agent quantity and pressure are within allowable range. 

This hypothesis can be illustrated, for example, on cooling lubricant emulsions as well as water-based coating and cleaning agent systems.
