The construction workers- professionalist and amateurs- wear dust masks (also called "disposable dust respirators") to protect themselves from many dangerous or harmful substances that are present on construction sites or in houses during construction, remodeling and demolition works in form of dust, mist or fume. Most dangerous are asbestos fibers, which are present in some type of roofing and in insulating and fireproof materials. There are although many dangerous substances in such environment: silica dust(silicosis risk!) from concrete and masonry, wood dust, paint chips and dust, fiberglass insulation( not asbestos, but also harmful or irritant to mucous membrames), sometimes mold and other chemicals. So, if the workers aren't stupid, they always wear dust mask! Working with mask on provides you longer life without serious and unpleasant lung diseases!
No, they may wear dust masks and/or a visor as some trees are very dusty
they had to wear masks. and they couldnt go to school
Conditions that involve small airborne particles (such as construction sites) are conditions that would require one to wear a dust mask. Similarly, if one is working with a hazardous chemical or substance (such as asbestos), a dust mask would be required to protect one's self from harm.
because there are smoke smoke is causingtuberculossis
I can provide information on the types of equipment and methods that construction workers often use to control dust while building houses: Water Spraying Systems: Water is sprayed onto dusty surfaces to suppress dust particles. Water trucks or hose attachments are commonly used for this purpose. Water can be applied to construction sites, roads, or surfaces to keep dust levels down. Dust Suppressants: Dust suppressant chemicals or additives can be applied to dusty areas to control dust. These chemicals can help prevent dust particles from becoming airborne. Dust Control Curtains and Barriers: Dust control curtains and barriers are physical barriers made of materials like mesh or fabric that enclose construction areas, preventing dust from spreading to neighboring areas. Vacuum Systems: Industrial vacuum systems equipped with dust collectors can capture dust particles at the source, reducing airborne dust. This is particularly useful for tasks like concrete cutting or grinding. Wet Cutting and Grinding: When cutting or grinding materials like concrete, using wet methods by applying water at the source of the work can prevent dust from becoming airborne. Dust Masks and Respirators: Construction workers often wear dust masks or respirators to protect themselves from inhaling dust particles. Local Exhaust Ventilation (LEV): LEV systems use fans and ductwork to capture and remove dust at the source, keeping the work area clean. Dust Control Equipment for Demolition: During demolition, equipment such as misting cannons or dust control units can be used to suppress dust and prevent it from spreading. Proper Site Management: Effective site management practices, such as regular cleaning, minimizing vehicle traffic, and covering materials, can help control dust on construction sites. Personal Protective Equipment (PPE): Construction workers should wear appropriate PPE, including safety glasses and clothing, to prevent dust exposure. Environmental Regulations: Construction sites are often subject to environmental regulations that require dust control measures to be implemented and followed. These dust control methods are important not only for the health and safety of workers but also for minimizing the environmental impact of construction activities and maintaining good relationships with neighbors and the community. Construction companies should be knowledgeable about local regulations and best practices for dust control to ensure compliance and safe working conditions.
Use wet methods. Follow established procedures and instructions. Wear the appropriate safety equipment including either supplied air full face masks or properly fitted filter masks. Use clean down rooms to remove surplus dust when leaving the area. Never use compressed air to blow off dust on clothing; use vacuums instead.
