The entry door fitted with a self closing device, with handles (internal and external) to prevent accidental locking and a 600 x 400 window of 20 mm impact resistance poly carbonate.
Seating along both walls is constructed from a formed sheet metal main frame with a storage facility provided under the seats. Seat material is a padded high grade durable material.
Inside the entrance there is an area sectioned off, by a heavy clear strip curtain, to minimize contaminates entering the Base from constant door opening and closing. This combined with the positive pressure maintained once the unit is activated will reduce the possibility of contaminates entering the Base.
Each Fresh air base has as standard, forklift guides, skid base and lifting facility for a crane and a crash bar is fitted around the refuge to minimize damage when transported. An IT attachment can be fitted to a customer’s configuration.
A high quality breathing air filter system is connected to mine air and this is fitted with a lever operated control valve.
Back up air supply is provided from air cylinders interconnected to the filter system.This maintains positive pressure during change over operations if a loss of mine compressed air occurs. The duration of breathable air is directly proportional to the number of air cylinders used.
The Base has large reflective signs fitted to all 4 sides that make it easier to find in a smoke filled environment. Directional arrows show the entrance and red and white reflective bands around the refuge also assist the unit to be located in poor visibility.
