The National Institute for Occupational Safety and Health (NIOSH) has issued a new warning alert similar to what you would find on tobacco products which states: “Warning! Occupants within damp office buildings, schools, and other nonindustrial facilities may develop respiratory symptoms and diseases”.
NIOSH defines “dampness” as “the presence of unwanted and excessive moisture in buildings”. It is widely known that excessive moisture and dampness can lead to mold growth, which can negatively impact the health of occupants by causing respiratory symptoms such as asthma, hypersensitivity pneumonitis, sinus infections, and other respiratory infections.
Dampness and moisture problems can often occur because of sub-optimal building design or lack of oversight during construction.
Here are some tips from NIOSH to prevent a moisture problem from occurring:
- Prevent high levels of indoor humidity through proper use of HVAC systems
- Conduct regularly scheduled inspections of heating, ventilating, and A/C systems
- Dry any porous surfaces that have become wet from leaks or flooding within the first 48 hours
- Clean and repair or replace any building materials that are moisture damaged or show evidence of mold growth
- Establish an Indoor Environmental Quality (IEQ) team to oversee implementation of an IEQ Program.
SkyeTec also recommends implementing a moisture prevention program during construction to ensure that the building is being properly constructed and sealed to avoid defects that could lead to a moisture problem later in the building's life cycle. It is much more cost-effective to take preventative action for moisture/dampness than it is to take remedial action.
With the amount of time that we all spend in the workplace or classroom, it makes sense for NIOSH to emphasize the importance of a quality indoor air environment and the resolution of dampness and moisture/mold problems.
Himalaya liver care> Respiratory disease may be a medical term that encompasses pathological conditions poignant the organs and tissues that build gas exchange possible in higher organisms, and includes conditions of the upper respiratory tract, trachea, bronchi, bronchioles, alveoli, pleura and pleural cavity, and the nerves and muscles of respiratory. metastasis diseases vary from mild and self-limiting, like the respiratory disease, to life-threatening entities like microorganism respiratory illness, pulmonary embolism, and lung cancer.
