Blast
Explosions pose a significant threat to critical national infrastructure (CNI) sites, government offices, utility sites, key assets, and densely populated areas, including stadia and commercial buildings. Whether caused by an accidental build-up of flammable material or a planned terrorist attack, the damage from heat, pressure and debris can result in critical loss of operations, assets and even human life.
Explosions are unexpected, swift, and powerful—locking systems installed for blast protection must provide tested and certified resistance that can be trusted at all times.
That’s why Tindall Engineering products have undergone rigorous testing and analysis to assess and certify their blast resistance capabilities.
The MICO multi-point locking system range has been specifically designed and tested to provide effective blast resistance, combined with high levels of physical-attack performance to protect life, assets and infrastructure. Tindall Engineering’s blast-resistant locking systems, when fitted to compatible doorsets, help contain the impact of positive and negative pressures generated by an explosion, reducing the likelihood of injury and property damage.
Our blast-resistant locking systems are available in a multitude of locking options, including emergency and panic escape, and mechanical and electro-mechanical deadlocking. Our range offers robust ‘fit for purpose’ blast-resistant, high-security solutions suitable for the most at-risk environments.



*Tested and certified as part of a complete doorset.

The pressure detailed in the table is equivalent to static load values, which is a conservative calculation method. The values in this table are based on an assumed door size and construction and are intended as an indicative guide. Calculations should be obtained from a blast consultant based on the door's response and the load capacity of the locking system's shootbolts. | ||
