Dust Exposure and Hazards
Exposure to dust can cause irritation to the eyes, skin, and respiratory tract. Prolonged exposure to dust can lead to serious lung diseases such as silicosis, coal workers’ pneumoconiosis (CWP), chronic obstructive pulmonary disease (COPD), and lung cancer.
Types of Dust Hazard
All airborne dust is hazardous to health. Dust can contain various materials like sand, dirt, pollen, minerals, wood, micro-organisms, and vehicle and industrial exhausts.
Dust Hazards – Physical and Chemical
Dust hazards include physical hazards like wind, rain, moisture, and non-ionizing radiation. Chemical hazards can arise from the formation of dust and the presence of combustible gases. Additionally, biological hazards like viruses and bacteria can be present in dust.
Dust as an Airborne Hazard
Dust is a common air pollutant, especially in regions with dry land. Severe droughts and dry conditions can increase the likelihood of airborne dust and major dust storms, particularly during summer months.
Health Impacts of Dust and Dirt
Exposure to dust inside homes can lead to respiratory problems, asthma, allergic reactions, and even lead poisoning if the dust contains lead. Dust can enter homes through various sources including dirt carried in from outside on shoes or blown in through windows and doors.
Occupational Hazards of Dust
Exposure to occupational dusts poses many hazards to workers’ health and safety. Large, airborne dust particles can obscure vision, limit mobility, and interfere with proper machine and equipment functioning.
Chemicals Found in Dust
Some commonly found chemicals in dust include phthalates, fragrance, flame retardants, and phenols. These chemicals are consistently found in a high percentage of dust samples across multiple studies.
Environmental Impacts of Dust
Dust has negative impacts on agriculture, reducing crop yields by burying seedlings, causing the loss of plant tissue, reducing photosynthetic activity, and increasing soil erosion.

Please note that the above answers are based on my personal experience and understanding.
What kind of hazard is dust
Exposure to dust can cause irritation to the eyes, skin and respiratory tract, and prolonged exposure can lead to a range of serious lung diseases including silicosis, coal workers' pneumoconiosis (CWP), chronic obstructive pulmonary disease (COPD) and lung cancer.
Is dust a chemical hazard
All airborne dust is hazardous to health. Dust can contain a range of materials including sand, dirt, pollen, minerals, wood, micro-organisms, and vehicle and industrial exhausts.
Is dust a physical or chemical hazard
The reported hazards include physical hazards such as wind, rain, moisture and non-ionizing radiation; chemical hazards, such as the formation of dust and combustible gases; and biological hazards, such as viruses and bacteria.
Is dust an airborne hazard
Dust is a common air pollutant, particularly in parts of the world with dry land. Periods of severe and widespread drought can increase the likelihood of airborne dust and major dust storms, particularly during the summer months.
What hazard is dust and dirt
Health Impacts
Exposure to dust inside homes can have adverse health outcomes, such as respiratory problems, asthma, allergic reactions, and lead poisoning (if the dust contains lead). Dust comes from two sources. First, dirt and dust can be carried in from outside on shoes or blown in through windows and doors.
Is dust an occupational hazard
Exposure to occupational dusts poses many hazards to workers' health and safety. Large, airborne dust particles can obscure vision, limit mobility while on the ground, and interfere with proper machine/equipment functioning.
What type of chemical is dust
Some phthalates, fragrance, flame retardants, and phenols are consistently found in 90 percent or more of dust samples across multiple studies. See a list of the top 10 chemicals found in dust.
Is dust an environmental hazard
Impacts on the environment and society
But dust also has many negative impacts on agriculture, including reducing crop yields by burying seedlings, causing loss of plant tissue, reducing photosynthetic activity and increasing soil erosion.
What state of matter is dust
Dust is made of fine particles of solid matter.
What are the three categories of dust
Different types of dust also carry different risks to human health and can be classified into three types: L Class (Low Risk), M Class (Medium Risk) and H Class (High Risk). Each class has a maximum allowable concentration, which is essential for employers to understand.
Is dust a type of matter
Particle pollution — also called particulate matter (PM) — is made up of particles (tiny pieces) of solids or liquids that are in the air. These particles may include: Dust. Dirt.
What is the scientific name for dust
Dust particles, often referred to as particulate matter (PM), in the atmosphere arise from a wide variety of sources. Both the size and chemical composition vary widely in relation to the nature of the source and the history of the particles.
What are the OSHA standards for dust
Employers will need to measure the amount of silica that workers are exposed to if it is at an action level greater than 25 micrograms per cubic meter of air. If silica exposures are above the PEL of 50 micrograms per cubic meter, proper protective measures must be taken. Limit high-risk access.
What is the OSHA standard for dust level
Further, dust is, itself, a potential health hazard. (As you are aware, OSHA has established a PEL for dust, referred to as Particulates Not Otherwise Regulated (PNOR).) The PELs for PNOR are as follows: 15 mg/m(3) for total dust and 5 mg/m(3) for the respirable fraction.
