Construction Safety Instructions
Construction workers must wear protective equipment such as reflective vest to ensure
safety during construction.
Construction sites must be blocked off and placed with signs. Specific requirements are as
follows:
Work on city road
: Place in sequence work zone warning sign, work zone speed limit sign,
and traffic guidance sign 150 meters away of coming vehicles from the work zone. In
addition, put work zone safety barriers at reasonable intervals to form a safe work zone and
protect workers’ safety.
Work on expressway
: Put work zone warning sign at safe area (such as near hard
shoulder or crash barrier) and 1.5 km away of coming vehicles from the work zone. In
addition, place in sequence work zone speed limit sign, traffic guidance sign, and work zone
distance sign around 150 meters to the work zone. Put work zone safety barriers at
reasonable intervals to form a safe work zone, and place traffic guidance sign at corners of
the work zone. Put sign of canceling work zone speed limit at a safe place 150 meters away
of leaving vehicles from the work zone.
Lifting work or aerial work
: The work zone must be placed with clear danger sign and
danger warning light at night. Responsible person should be designated to guide people to
detour. Do not enter or stay in work area.
Aerial work platform
: Make sure that its parking position is ideal for aerial work. Check
whether the support legs of aerial work platform are put in place to support the telescopic
boom, and whether heavy-current circuit is connected within the work zone. Make sure the
boom will not touch any object when it is extended.
Workers should fasten safety belt and wear helmet, and properly place equipment, tools
and personal belongings to prevent injuries from falling objects.
Heavy current engineering
: During wiring, joint with the heavy current part exposed should
be wrapped with insulated and waterproof tape, which will be put into waterproof insulated
box. When the device is connected to heavy current, make sure the circuit works, and the
insulation cover of cable is inserted into terminal to prevent the insulation cover separating
from the copper wire, resulting in the copper wire exposed. For old wire construction, make
sure no power is connected, and then start construction.
Grounding
: Make sure all electric devices are properly grounded during construction.
