Lighting is particularly important during nighttime construction. Do you know what precautions should be taken for lighting?
In summer, it is hot and hot. In order to avoid the reduction of construction quality and heatstroke caused by high temperature, and to ensure the construction progress, many construction projects choose to avoid the high temperature period at noon and switch to shady periods in the morning and evening and night construction.
Effective lighting is essential for night construction, so what should be paid attention to in night construction lighting?
General Safety Requirements
General, partial lighting or mixed lighting shall be provided in workplaces, material storage yards, roads, warehouses, offices, canteens and dormitories that require lighting. In one workplace, only partial lighting shall not be provided.
The illumination of the construction site at night should meet the needs of the construction process and meet the design requirements of the temporary power consumption scheme.
When working at night, there should be sufficient lighting facilities in the working area, and the lamps should be complete and intact.
Red warning lighting must be installed at construction sites or facilities and equipment that may affect the safe passage of pedestrians and vehicles at night.
After a power failure, the construction site where operators need to evacuate in time must be equipped with emergency lighting with its own power supply.
On-site lighting should use high-efficiency, long-life lighting sources. For places requiring large-area lighting, high-pressure mercury lamps, high-pressure sodium lamps or LED work lamps should be used.
Construction site lighting safety requirements
(1) The power supply voltage of construction lighting shall meet the following requirements:
In general places, the lighting voltage should be 220V. Tunnels, civil air defense projects, high temperature, conductive dust and narrow places, the lighting voltage should not be greater than 36V.
The lighting voltage should not be greater than 24V in damp and easily accessible lighting circuits.
The lighting voltage should not be greater than 12V in the ground, boiler or metal container that is particularly humid and has good electrical conductivity.
The line lamp voltage should not be greater than 36V.
On-site lighting lines must be made of soft rubber sheathed lines and equipped with leakage protectors. The metal casing of the luminaire should be grounded (zero) protected.
The phase wire of the lighting lamp should be controlled by the switch, and the phase wire should not be introduced directly. The system of "one machine, one gate" must be implemented, and it is strictly forbidden for the same switch to directly control two or more electrical equipment (including sockets). Overhead lines must use insulated copper wire or insulated aluminum wire. The metal bracket of the mobile iodine-tungsten lamp shall be reliably grounded (zero), and the height of the lamp from the ground shall not be less than 2.5m. The high-pressure dysprosium lamp mounting bracket should be sturdy and reliable, and should have rain-proof measures. Construction lighting Outdoor lamps and lanterns shall not be less than 3m from the ground, and indoor lamps shall not be less than 2.5m from the ground. The 220V iodine-tungsten lamp used for construction lighting should be fixedly installed, its height should not be less than 3m, and the distance from the flammable material should not be less than 500mm, and the flammable material should not be directly illuminated, and the 220V iodine-tungsten lamp should not be used as mobile lighting. The form and protection level of electric lighting appliances for construction shall be adapted to the environmental conditions. For places that require construction at night or in dark places, emergency lighting power must be configured.
LED work lights for construction lighting at night
LED work lights are suitable for all kinds of temporary construction lighting, short-term maintenance tasks, tunnels, auto repair rooms, coal mines, machine rooms, garages, mechanical maintenance work, warehouses, factories, workshops, construction sites, highway toll stations, gas stations, showrooms, basements , industrial and emergency services, etc. , LED work light is a relatively common lighting equipment, and is also suitable for small and medium-sized work environments. Each work light does not generate heat during use, has low power, soft light and long service life. It is an environmental lighting facility. , has a very wide range of uses. With 360° omnidirectional lighting, it can bring clear light even in dark corners, creating a bright environment. For commercial and industrial professional lighting needs. Energy consumption can be reduced by 90%.
