Take protection and isolation measures for the ESS, such as installing fences,
walls, and safety warning signs to prevent personal injury or property damage
caused by unauthorized access during operations.
To prevent fire due to high temperatures, ensure that vents and heat
dissipation systems are not obstructed while the equipment is running.
Install the equipment in an area far away from liquids. Do not install it under
areas prone to condensation, such as water pipes and air exhaust vents, or
areas prone to water leakage, such as air conditioner vents, ventilation vents,
or feeder windows of the equipment room. Ensure that no liquid enters the
equipment to prevent faults or short circuits.
Keep the equipment away from fire sources. Do not place any flammable or
explosive materials around the equipment.
If the equipment is installed in a place with dense vegetation, in addition to
routine weeding, harden the ground under the equipment to prevent weeds
from growing.
The site must be a class C or higher environment but not a class D or E
environment.
NO TE
● Class C environment: Outdoor areas more than 500 m away from the sea. If a site
is near a pollution source, it must be 1500–3000 m away from heavy pollution
sources, such as smelteries, coal mines, and thermal power plants; 1000–2000 m
away from medium pollution sources such as chemicals, rubber, and galvanization;
or 500–1000 m away from light pollution sources, such as packing houses,
tanneries, boiler rooms, slaughterhouses, landfill sites, and sewage treatment
plants.
● Class D environment: Sea environments or outdoor areas within 500 m away from
the sea. If a site is near a pollution source, it is within 1500 m away from heavy
pollution sources such as smelteries, coal mines, and thermal power plants, within
1000 m away from medium pollution sources such as chemical, rubber, and
galvanization industries, or within 500 m away from light pollution sources such as
packing houses, tanneries, boiler rooms, slaughterhouses, landfill sites, and sewage
treatment plants.
● Class E environment: Special environments, such as underground or underwater
environments.
Wear PPE such as safety helmet, safety belt, and waist rope fastened to a
solid structure. Do not mount it on an insecure and moveable object or metal
object with sharp edges. Make sure that the hooks will not slide off.
Set a restricted area and put up prominent signs for working at heights. Only
related personnel can enter the area.
Do not pile up scaffolding, springboards, or other objects on the ground under
the area involving working at heights. Do not allow people to stay or pass
under the area involving working at heights.
Personnel involving working at heights are not allowed to throw objects from
the height to the ground, or vice versa. Objects should be transported by
ropes, hanging baskets, highline trolleys, or cranes.
Inspect the scaffolding, springboards, and workbenches used for working at
heights in advance to ensure that their structures are solid and not
overloaded.
