SJH Projects provide consultancy, testing and a range of products to protect against the effects of blasts. Projects have been undertaken in counter-terrorism, landmine and IED protection and the storage and transportation of munitions. Other more specialist blast protection applications have also been dealt with for customer-specific requirements.
XPT BLAST PROTECTION MATERIAL
SJH Projects has its own blast mitigation material – XPT. This is used in a number of the company&squo;s products such as the Mailsafe and Detsafe ranges. It is comprised of sacrificial bonded material that absorbs a large amount of kinetic energy when broken up in blast waves. XPT can also be used as part of a system to protect vehicles from underside blasts such as landmines or roadside bombs.
DETONATOR TRANSPORTATION CONTAINERS
The movement or storage of detonators can create logistical hurdles and added expense. SJH Projects detonator containers are designed to reduce the hazard classification of transporting detonators down to the same level as small-arms rounds. This provides much greater flexibility and safety for all those who have to work with or around such items. Certification to 1.4S is the responsibility of national Competent Authorities and is detonator specific. SJH Projects can assist with the certification process.
SJH Projects can produce a variety of configurations using standard and modified ammunition boxes. In the event of a detonator firing, the XPT chambers inhibit propagation and insulate the detonators from heat ‐ essential for transportation approval and protection in a road traffic accident with its inherent risk of fire.
FUELSAFE PROTECTIVE JERRYCANS
Long distance operations in the field often require additional supplies of fuel. The jerrycan is the age old tool for this job, but if such operations are in a hazardous environment the transportation of unprotected fuel on vehicle roof racks is an unnecessary risk. Tested with hand grenades, the Fuelsafe protective jerrycan protects both petrol and diesel from close range explosive devices.
VEHICLE MINE AND IED PROTECTION
Because of the way in which XPT blast protective material absorbs blast and dampens accelerations and the through transmission of energy, it is ideal for use on the underside of vehicles. It can be used to enhance the protection of armoured vehicles or to provide landmine protection to soft skinned vehicles. For soft skinned vehicles the stiffness of the body has to be upgraded, which is best achieved through the use of a roll cage. SJH Projects can work with each customer to make sure that all the factors that affect survivability are addressed, so that the XPT-based system becomes part of a viable protection system.
BUILDING BLAST PROTECTION PANELS
XPT blast mitigation panels can be used as an effective blast cladding system. Ideal for mail screening rooms and explosive storage and processing facilities, they are simple to erect and remove at a later date if required. One of the key benefits of XPT panels is that they absorb a high proportion of the blast. This greatly reduces the damaging effects that take place when reflected blast waves interact.
When conditions dictate, the XPT system is further enhanced with ballistic fibre reinforced composite panels. Extensive experience in the use of such composites ensures that the result will be most efficient and cost-effective.
