Powershield Blast & Ballistic
Powershield Blast
Powershield has been supplier of blast products to most of the drug manufacturers in the FORTUNE 500 list of companies.
The wide use of solvents during the drug manufacturing process results in potential hazards from blast situations. It is, therefore, imperative that the process plant designers make provision for the containment of any such blast incidents.
A considerable number of pharmaceutical blast situations are also in cleanroom-rated areas and thus require blast rated vision screens from a room into the process area. Powershield has developed such a vision screen design as part of the blast package.
Blast doors must have the ability to withstand the physical force of a pressure surge yet simultaneously have an appealing aesthetic appearance in line with the other doors in the plant. They must also be easy to operate in day to day use by male and female staff of any build. These are all defining criteria we have been sure to incorporate into our designs.
Critical design elements of our blast resistant doors are:
- door remains shut during blast
- door can be opened after blast
- no plastic or permanent deformation of door or frame takes place
- frame remains secure in wall
- door unit offers ease of operation in normal use
Blast doors have been designed to resist blast pressure from 0.5 – 50KN/m2 and are available in single leaf, double leaf and leaf & ½ configurations
Powershield Ballistic
With the unfortunate increase in gun crime and risk from terrorist attack Powershield have developed a range of ballistic resistant doors to provide protection against attack by firearms. Doors have been independently tested to BS 5051, BS EN 1063, BS EN 1522 & BS EN 1523 to withstand penetration from a variety of weapons classified under the European standard from B1 – B6
