We are in the midst of rainy season and very heavy at that, this year.
There are reports and photos showing road formations and bridges damaged,
villages destroyed, Sarpang market washed-out, traffic interrupted, people stranded
and supply of essential items disrupted. It is a natural calamity. People
are panicking, worried and some even depressed. This is no time to put our
heads down. Let us all keep our heads on our shoulders, keep spirit high and
move on using our mind, belief, dedication and commitment.
In times like this I have seen in many places, time becomes very
critical factor. Everyone will have their own account of losses because of
disruption created by the natural calamity. Pressures to connect roads, rebuild
bridges, resettle villagers, and relocate markets quickly build up. The
authorities like to display their efficiency in handling emergency
situation. This is no time to panic and make mistakes. The decisions should not
be made making only time as the critical factor. We should prioritize safety above
time. Let us not put lives at high risk to get things back on track
haphazardly. So I say, SAFETY FIRST.
The critical areas where safety measures need to be implemented
from beginning are roads and bridges. On roads and highways safety has to be
ensured in two ways: (i) through technical measures; and (ii) traffic management
& control.
(i) Technical
Measures
(a) Ensure
all structures are technically safe before opening the road to traffic.
(b) Stability
of bridge abutments is critical if temporary bridges are being launched.
(c) Fresh
cut areas need adequate formation widths and set back slopes;
(d) Ensure
water is drained out from the area as quickly as possible.
(e) No
unstable hanging rocks should be kept above the road.
(f) After
opening the road to traffic, constantly monitor the area by competent technical
person for unusual soil and structural movements/behaviours.
(g) The
installation/construction of road/bridge structures should be planned in
such a way that (i) construction of permanent roads/bridges could continue
without hindrances; and (ii) road workers are not put to high safety risk.
(ii) Traffic
Management and Control (more critical where traffic volume is high)
(a) To
avoid traffic bottlenecks, traffic management & control plan should be
prepared for controlling traffic from two points on both sides. The first point
should be about 5 km before reaching the critical area, and second at the entry
point of critical area.
(b) Two
way traffic should not be allowed on fresh cuts or on temporary bridges.
(c) Bridge
should take one vehicle at a time. Two or more vehicles should not be permitted
on the bridge.
(d) The
traffic management & control plan should be widely circulated to public.
(e) Vehicles
should not be allowed to ply on critical areas during heavy rain.
Let us move ahead in one
direction with much sense, not in multi-direction on panic-mode!
