ATM HS-1 Shelter Hatch: Blast and Gastight Protection for S1 Shelters
The ATM HS-1 is a shelter hatch designed for use in protected spaces. According to the product information provided by Shelter Shop, the hatch is designed to meet and, in some parameters, exceed the Finnish norms for S1 shelters.
The ATM HS-1 combines blast resistance with gas-tight sealing and is designed with an inward-opening configuration. Its construction and locking system are intended for installation in shelter structures requiring protection against blast-wave pressure and gas leakage.
Design and Construction
The hatch leaf is manufactured from a 20 mm thick single steel plate.
The ATM HS-1 uses an inward-opening design. According to the product description, the hatch is equipped with a multipoint locking system with locking bolts, providing improved protection against blast-wave pressure.
A rubber seal is incorporated into the hatch to provide gas tightness.
Blast Resistance
The specified blast resistance of the ATM HS-1 is:
200 kN/m² (2 bar)
This is the blast-resistance value published in the product information.
The hatch's locking mechanism and steel construction form part of the design intended to provide protection against blast-wave pressure.
Gas Tightness
The ATM HS-1 is equipped with a seal for gas tightness.
The rubber sealing element is integrated into the hatch construction to provide the specified gas-tight function.
This characteristic is particularly relevant to shelter applications where maintaining the integrity of the protected internal space is required.
Installation Options
The product information specifies several installation options for the ATM HS-1:
Casting installation
Retrofit installation
Right-hand or left-hand configuration
The specified standard wall thickness is 300 mm.
Locking System
The ATM HS-1 uses a locking mechanism with 2 locking bolts.
The product description identifies the multipoint locking system and locking bolts as elements of the hatch design intended to improve protection against blast-wave pressure.
