118 Dust Explosions in the Process industries
As long as there are no special reasons for choosing other solutions, it is recommended
that factory buildings in which dust explosions may occur, be constructed as indicated
in Figure 1.136. The basic principle is that the roof and intermediate floors are supported
by a strong frame structure. The walls are lightweight panel sections that function as vent
covers, should an explosion occur. If required, the panels may be anchored to the frame
structure (see Figure 2.7).

Figure 1.1 36 Recommended construction of factory buildings to prevent collapse of building in a
dust explosion.
Some final points to be taken into account when planning the layout and construction
of factory buildings to reduce the explosion and fire hazard, include
0 Safe escape routes in case of explosion and fire.
0 Fire-resistant construction materials.
Fire-resistant doors.
Electrical installations according to latest regulations and recommendations.

THE “HUMAN FACTORS”
Proper construction and maintenance of an integrated system for preventing and miti-
gating dust explosions very much depends on human relations and human behavior.
A number of different personnel categories may be involved, including
Workers and foremen in the plant.
Workers from the maintenance department.
Plant engineers.
Safety engineers.
kchasing department officers.
Safety manager.
