Protective and Control Measures for Workshop Dust

Wiki Article

Workshops of enterprises such as coking plants, cement plants and coal yards generate large amounts of dust during operation. In addition, many other production workshops produce industrial dust like iron powder, aluminum powder and wood dust in the course of production. Such dust not only pollutes the environment, but also endangers the health and safety of workers. Then what methods can be adopted to control such heavy dust in workshops?

1.Reforming process equipment and operational methods, and avoiding the use of raw materials or production process routes with high risks are important approaches to eliminate and reduce dust hazards.

2.For large-space, high-dust and unfixed dust-source places such as coking plants, cement plants, construction sites and coal yards, spray dust suppression equipment including tower crane spray systems, fog cannons, high-pressure dry fog dust suppression devices and detachable windproof dust suppression nets can be adopted.

3.Dust collection and purification: According to the properties, concentration, dispersion degree and emission volume of dust, dust collection and purification facilities shall be used to eliminate and purify dust in the air and prevent secondary dust emission.

4.Constantly supply clean and fresh air to the workplace, dilute the dust concentration in the air, and discharge the contaminated air outdoors, so as to dilute the harmful dust in the working area to the corresponding permissible concentration. Ventilation and air exchange facilities shall be adopted for this purpose.

5.Workshop dust enters the human body mainly through three routes: first, inhalation, which means entering the body through the respiratory tract; second, cutaneous absorption, which means penetrating into the body through sweat glands, sebaceous glands and hair follicles on the skin surface; third, ingestion, which means getting into the body through the digestive tract. Targeted personal protection should be carried out according to the ways dust harms the human body and the routes of exposure.

The specific measures are as follows: select and wear appropriate types of dust-proof masks and respirators based on the properties of different dusts to block dust from entering the respiratory system; wear work clothes, helmets, goggles and other protective gear correctly to prevent dust from contacting the skin; and prohibit eating, smoking, drinking and other activities at the dust-generating work sites.

Only through the implementation of such a combination of measures can workshop dust be effectively controlled, the working environment of workers be purified, and environmental pollution be reduced.
