Various materials are explosive in the form of dust. Some examples are: foods (e.g. candy, sugar, spices, starches, flours and animal feeds), grains, tobacco, plastics, wood, paper, pulp, rubber, drugs pesticides, pharmaceuticals, dyes, coal and metals (e.g.:, aluminum, chromium, iron, magnesium and zinc). These materials are used in agriculture, chemical manufacturing, pharmaceutical manufacturing, furniture, textiles, fossil fuel power generation, recycling operations, metalworking and transformation ( including additive manufacturing and 3D printing) as well as in many other industries and processes.
In addition to posing a fire hazard, certain types of dust can pose a health hazard. Exposure (such as skin contact, eye contact, and inhalation) may be associated with sneezing, nasal congestion or discharge, itchy or red eyes, headache, fatigue, fever, cough, difficulty breathing, dermatitis, asthma, bronchitis, pneumonia (eg, Legionnaires' disease and hypersensitivity pneumonitis) and cancer.
When inhaled, PM 2.5 and PM 10 particles can be deposited deep in the lungs and cause adverse health effects. Since the PCE-PCO 2 particle counter monitors PM 2.5 and PM 10 particles, it has many practical health and safety applications. Heating, Ventilation and Air Conditioning (HVAC) technicians use PM 2.PM 5 and PM 10 particle counters for HVAC system performance and filtration testing. In addition, industrial hygienists and occupational safety professionals rely on PM 2.5 and PM 10 particle counters to assess occupational health and safety risks from hazardous and flammable dusts.
