Design protection

Corrosion is fought partly by developing alloys with a built-in proclivity to form protective oxide layers, such as stainless steels , and partly by designing protective coatings. A form of protection particularly closely linked to electrochemistry is... 

In the UK these duties are imposed by the Health and Safety at Work etc. Act. Employees also have a legal responsibility to cooperate with management by using designated protective devices and not interfering with such apparatus. 

Designate protected raw material and hazardous waste storage areas with spill containment. Keep the areas clean and organized and give one person the responsibility for maintaining the areas. 

This accident was attributed to the lack of design protection to prevent the backup of ammonia into this storage tank. It also appears that mitigation techniques were not part of the system (deluge systems, dikes, and the like). 

Normal loss prevention practices are to design protection measures for the worst case fire event that can occur at the facility. To interpret this literally would mean that an oil or gas facility is completely on fire or totally destroyed by an explosion. Practical, economical and historical review considerations indicate this rational should be redefined to the Worst Case Credible Event (WCCE) or the as referenced in the insurance industry, the Probable Maximum Loss (PML), that could occur at the facility. 

A unique feature of the Foster Wheeler SCWO reactor is its full-length transpiring-wall liner, shown in Figure 4-2. Foster Wheeler claims that this liner design protects the reactor walls from corrosion and salt deposition. The reactor liner is fabricated from multiple layers of Inconel 600 assembled in sheets of what the technology provider refers to as platelets to produce transpiration pores. Deionized water is added to the SCWO reactor through transpiration pores in the liner... 

The final Study reported here was just completed by Ruth King, a Doctoral student at The University of Tennessee. The Intent of the study was to evaluate the effects of perceived product attributes of functionally designed protective apparel and of risk related factors influencing the adoptlon/purchase decision (9). This discussion will focus on the first objective, which was to determine if significant differences existed between garment selection when information was withheld relative to the product attributes of cost, comfort and penetration.
