Mold Remediation >> Mold Exposure Symptoms

Remediation can be conducted by the regular building maintenance staff. Such persons should receive training on proper clean-up methods, personal protection, and potential health hazards. This training can be performed as part of a program to comply with the Mold Exposure Symptoms requirements of the OSHA Hazard Communication Standard (29 CFR 1910.1200). 

Respiratory protection (e.g., N-95 disposable respirator) is recommended. Respirators must be used in accordance with the OSHA respiratory protection standard (29 CFR 1910.134). Gloves and Mold Exposure Symptoms eye protection should be worn. The work area should be unoccupied. Removing people from spaces adjacent to the work area is not necessary, but is recommended for infants (less than 12 months old).

Persons recovering from recent surgery, immune-suppressed people, Mold Exposure Symptoms or people with chronic inflammatory lung diseases (e.g., asthma, hypersensitivity pneumonitis, and severe allergies). Surfaces in the work area that could become contaminated should be covered with a secured plastic sheet(s) before remediation to contain dust/debris and prevent further contamination. 

Dust suppression methods, Mold Exposure Symptoms such as misting (not soaking) surfaces prior to remediation, are recommended. Contaminated materials that cannot be cleaned should be removed from the building in a sealed impermeable plastic bag. These materials may be disposed of as ordinary waste. The work area and areas used by remediation workers for egress should be HEPA vacuumed and cleaned with a damp cloth or mop and a detergent solution. 

All areas should be left dry and visibly free from contamination and debris. Level III: Large Isolated Areas (30 –100 square feet) – e.g., Mold Exposure Symptoms several wallboard panels. Industrial hygienists or other environmental health and safety professionals with experience performing microbial investigations and/or mold remediation should be consulted prior to remediation activities to provide oversight for the project. 

The following procedures may be implemented depending upon the severity of the contamination: It is recommended that personnel be trained in the handling of hazardous materials Mold Exposure Symptoms and equipped with respiratory protection (e.g., N-95 disposable respirator). Respirators must be used in accordance with the OSHA respiratory protection standard (29 CFR 1910.134). 

Gloves and eye protection should be worn. Surfaces in the work area Mold Exposure Symptoms and areas directly adjacent that could become decontaminated should be covered with a secured plastic sheet(s) before remediation to contain dust/ debris and prevent further contamination. Seal ventilation ducts/grills in the work area and areas directly adjacent with plastic sheeting. 

The work area and areas directly adjacent should be unoccupied. Removing people from spaces near the work area is recommended for infants, Mold Exposure Symptoms persons having undergone recent surgery, immunesuppressed people, or people with chronic inflammatory lung diseases. (e.g., asthma, hypersensitivity pneumonitis, and severe allergies). 

Dust suppression methods, such as misting (not soaking) surfaces prior to mediation, are recommended. Contaminated materials that cannot be cleaned should be removed from the building in sealed impermeable plastic bags. These materials may be disposed of as ordinary waste. The work area Mold Exposure Symptoms and surrounding areas should be HEPA vacuumed and cleaned with a damp cloth or mop and a detergent solution. 

All areas should be left dry and visibly free from contamination and debris. Note: If abatement procedures are expected to generate a lot of dust (e.g., abrasive cleaning of contaminated surfaces, Mold Exposure Symptoms demolition of plaster walls) or the visible concentration of the mold is heavy (blanket coverage as opposed to patchy), it is recommended that the remediation procedures for Level IV be followed. 

Level IV: Extensive Contamination (greater than 100 contiguous square feet in an area). Industrial hygienists or other environmental health Mold Exposure Symptoms and safety professionals with experience performing microbial investigations and/or mold remediation should be consulted prior to remediation activities to provide oversight for the project. 

The following procedures may be implemented depending upon the severity of the contamination: Personnel trained in the handling of hazardous materials and equipped with: Full face piece respirators with HEPA cartridges; Mold Exposure Symptoms Disposable protective clothing covering entire body including both head and shoes; and Gloves. 

Containment of the affected area: Complete isolation of work area from occupied spaces using plastic sheeting sealed with duct tape (including ventilation ducts/grills, fixtures, Mold Exposure Symptoms and other openings); The use of an exhaust fan with a HEPA filter to generate negative pressurization; and Airlocks and decontamination room. 

If contaminant practices effectively prevent mold from migrating from affected areas, it may not be necessary to remove people from surrounding work areas. However, removal is still recommended for infants, persons having undergone recent surgery, Mold Exposure Symptoms immune- suppressed people, or people with chronic inflammatory lung diseases. (e.g., asthma, hypersensitivity pneumonitis, and severe allergies). 

Contaminated materials that cannot be cleaned should be removed from the building in sealed impermeable plastic bags. The outside of the bags should be cleaned with a damp cloth Mold Exposure Symptoms and a detergent solution or HEPA vacuumed in the decontamination chamber prior to their transport to uncontaminated areas of the building. 

These materials may be disposed of as ordinary waste. The contained area and decontamination room should be HEPA vacuumed and cleaned with a damp cloth or mopped with a detergent solution Mold Exposure Symptoms and be visibly clean prior to the removal of isolation barriers. Personal Protective Equipment (PPE) Any remediation work that disturbs mold and causes mold spores to become airborne increases the degree of respiratory exposure. 

Actions that tend to disperse mold include: breaking apart moldy porous materials such as wallboard; destructive invasive procedures to examine or remediate mold growth in a wall cavity; removal of contaminated wallpaper by stripping or peeling; Mold Exposure Symptoms using fans to dry items or ventilate areas. The primary function of personal protective equipment is to prevent the inhalation and ingestion of mold and mold spores and to avoid mold contact with the skin or eyes. 

The following sections discuss the various types of PPE that may be used during remediation activities. Skin and Eye Protection Gloves protect the skin from contact with mold, Mold Exposure Symptoms as well as from potentially irritating cleaning solutions. Long gloves that extend to the middle of the forearm are recommended. 

The glove material should be selected based on the type of substance/ chemical being handled. If you are using a biocide such as chlorine bleach, or a strong cleaning solution, Mold Exposure Symptoms you should select gloves made from natural rubber, neoprene, nitrile, polyurethane, or PVC. If you are using a mild detergent or plain water, ordinary household rubber gloves may be used. 

To protect your eyes, Mold Exposure Symptoms use properly fitted goggles or a full face piece respirator. Goggles must be designed to prevent the entry of dust and small particles. Safety glasses or goggles with open vent holes are not appropriate in mold remediation. Respiratory Protection Respirators protect cleanup workers from inhaling airborne mold, contaminated dust, and other particulates that are released during the remediation process. 

Either a half mask or full face piece air-purifying respirator can be used. A full face piece respirator provides both respiratory Mold Exposure Symptoms and eye protection. Please refer to the discussion of the different levels of remediation to ascertain the type of respiratory protection recommended. Respirators used to provide protection from mold and mold spores must be certified by the National Institute for Occupational Safety and Health (NIOSH). 

More protective respirators may have to be selected Mold Exposure Symptoms and used if toxic contaminants such as asbestos or lead are encountered during remediation. As specified by OSHA in 29 CFR 1910.134 individuals who use respirators must be properly trained, have medical clearance, and be properly fit tested before they begin using a respirator. 

In addition, use of respirators requires the employer to develop and implement a written respiratory protection program, Mold Exposure Symptoms with worksite-specific procedures and elements. Protective Clothing While conducting building inspections and remediation work, individuals may encounter hazardous biological agents as well as chemical and physical hazards. 

Consequently, appropriate personal protective clothing (i.e., reusable or disposable) is recommended to minimize cross-contamination between work areas and clean areas, to prevent the transfer and spread of mold and other contaminants to street clothing, Mold Exposure Symptoms and to eliminate skin contact with mold and potential chemical exposures. 

Disposable PPE should be discarded after it is used. They should be placed into impermeable bags, and usually can be discarded as ordinary construction waste. Appropriate precautions Mold Exposure Symptoms and protective equipment for biocide applicators should be selected based on the product manufacturer's warnings and recommendations (e.g., goggles or face shield, aprons or other protective clothing, gloves, and respiratory protection).
