Hercules II TM: The Hercules IITM

is designed to resist an external explosion of magnitude equivalent to a static load of >30kN/m2 for the protection of personnel in the petrochemical industry. It has been used extensively in petrochemical and chemical plants and facilities to protect lives around the Asean Region. Fire Rating: Up to 4 hours (240 minutes) to BS 476:Part 22:1987; ISO 3008; SS 332:2007.

Hercules I TM: The Hercules ITM

is a fire-exit door designed as an antiterrorist barrier to resist an explosion equivalent to 20kg of TNT at a distance of 15 m from either side of the door leaf. Equivalent to a peak incident

over-pressure of 400 millibar over a duration of 10 milliseconds. The Hercules ITM

blast resistant door is designed to

function with and comes complete with proprietary TACAMTM hardware, consisting of a patented multiple-point blast resistant lockset, heavy duty door closers, proprietary hinges and a self-sealing pressure barrier to close the leaf-to-ground gap. Fire Rating: Up to 4 hours (240 minutes) to BS 476:Part 22:1987; ISO 3008; SS 332:2007.

TESTED BLAST RESISTANT DOORS

The Techsteel Group is oneof very few companies in theworld that have an ongoingproof and experimental testingresearch and developmentprogram that puts its blast doorsdesigned to take a particularblast load through actual tests.This is achieved through a closecollaboration with a researchauthority from the ProtectiveTechnology Research Centre ofthe Nanyang TechnologicalUniversity in Singapore & thePort Wakefield Proof andExperimental Station in SouthAustralia.

Most blast resistant doorsare built only to design and atbest these designs aresupported by simulation studiesbut never subjected to actualblast tests. This is because ofthe high cost of a blast test andthe difficulty of securing accessto a testing facility as there arevery few commercial testfacilities. The Techsteel Groupis also a participant in multi-nation collaborative tests suchas the 5,000 kg equivalent ofTNT high-explosives blast testat Woomera, Australia inOctober 2002.

TACAM blast doors are firstdesigned based on engineeringcalculations, correlated to avast pool of past in-house dataand experience. These in-house calculations are thensubmitted to a ProfessionalEngineer (P.E.) with formidableexperience in the field of BlastProtection Technology tosubstantiate the requiredloadings. Where appropriate,further refinements are madethrough the use of cutting-edgecomputer-simulation modelsand techniques. Finally, theentire door system is prooftested on a military facility inAustralia, where the datacollected with transducers andaccelerometers is analyzed tounderstand the response of thestructure. A high-speed camerais used to study thedeformation of the door panels.

It is only in actual field tests thatthe door components such asthe hinges and locksets andtheir interface to the door paneland frame can be proven asthese complex 3-dimensionalsystems cannot be easilyverified through simulations.

In the Port Wakefield testsin June 2001, 110 kg of highexplosive equivalent was set offto test 5 TACAM blast resistantdoors. This not only proved thatthe five doors could take theblast load they were designedfor, it provided valuable data forfuture improvements anddevelopment. The tests led toimproved ironmongery fixturesso that the doors would not onlytake the deformations due tothe blast but the door leavescould continue to be openedand closed after the blast.
