Asbestos Abatement >> How To Remove Asbestos Pipe Insulation

Pressure Differential: The design parameters for static pressure differentials between the inside and outside of enclosures typically range from 0.02 to 0.10 inches of water gauge, depending on conditions. All zones inside the enclosure must have less pressure than the ambient pressure outside of the How To Remove Asbestos Pipe Insulation enclosure (-0.02 inches water gauge differential). 

Design specifications for the differential vary according to the size, configuration, and shape of the enclosure as well as ambient and mechanical air   reassure conditions around the How To Remove Asbestos Pipe Insulation enclosure. Air Flow Patterns: The flow of air past each worker shall be enhanced by positioning the intakes and exhaust ports to remove contaminated air  from the worker's breathing zone.

By positioning HEPA vacuum cleaners to draw air from the worker's breathing zone, by forcing relatively uncontaminated air past the worker toward an exhaust port, or by using a combination of  How To Remove Asbestos Pipe Insulation methods to reduce the worker's exposure. 

Air Handling Unit Exhaust: The exhaust plume from air handling units should be located away from adjacent personnel and intakes for HVAC systems. Air Flow Volume: The air flow volume (cubic meters per minute) exhausted (removed) from the workplace must exceed the amount of makeup air supplied to the How To Remove Asbestos Pipe Insulation enclosure. 

The rate of air exhausted from the enclosure should be designed to maintain a negative pressure in the enclosure and air movement past each worker. The volume of air flow removed from the How To Remove Asbestos Pipe Insulation enclosure should replace the volume of the container at every 5 to 15 minutes. 

Air flow volume will need to be relatively high for large enclosures, How To Remove Asbestos Pipe Insulation enclosures with awkward shapes, enclosures with multiple openings, and operations employing several workers in the enclosure. Air Flow Velocity: At each opening, the air flow velocity must visibly "drag" air into the enclosure. 

The velocity of air flow within the How To Remove Asbestos Pipe Insulation enclosure must be adequate to remove airborne contamination from each worker's breathing zone without disturbing the asbestos-containing material on surfaces. Airlocks: Airlocks are mechanisms on doors and curtains that control the air flow patterns in the doorways. 

If air flow occurs, the patterns through doorways must be such that the air flows toward the inside of the How To Remove Asbestos Pipe Insulation enclosure. Sometimes vestibules, double doors, or double curtains are used to prevent air movement through the doorways. 

To use a vestibule, a worker enters a chamber by opening the door or curtain and then closing the entry before opening the exit door or curtain. Airlocks should be located between the equipment room and shower room, between the shower room and the clean room, and between the waste storage area and the outside of the How To Remove Asbestos Pipe Insulation enclosure. 

The air flow between adjacent rooms must be checked using smoke tubes or other visual tests to ensure the flow patterns draw air toward the work area without producing eddies. Monitoring for Airborne Concentrations In addition to the breathing zone samples taken as outlined in paragraph (f) of this How To Remove Asbestos Pipe Insulation section.

Samples of air should be taken to demonstrate the integrity of the How To Remove Asbestos Pipe Insulation enclosure, the cleanliness of the clean room and shower area, and the effectiveness of the HEPA filter. If the clean room is shown to be contaminated, the room must be relocated to an uncontaminated area. Samples taken near the exhaust of portable ventilation systems must be done with care. 

General Work Practices Preventing dust dispersion is the primary means of controlling the spread of asbestos within the enclosure. Whenever practical, the point of How To Remove Asbestos Pipe Insulation removal should be isolated, enclosed, covered, or shielded from the workers in the area. 

Waste asbestos containing materials must be bagged during or immediately after removal; the material must remain saturated until the How To Remove Asbestos Pipe Insulation waste container is sealed. Waste material with sharp points or corners must be placed in hard air-tight containers rather than bags. Whenever possible, large components should be sealed in plastic sheeting and removed intact. 

Bags or containers of waste will be moved to the waste holding area, washed, and wrapped in a bag with the appropriate labels. Cleaning the How To Remove Asbestos Pipe Insulation Work Area Surfaces within the work area should be kept free of visible dust and debris to the extent feasible. 

Whenever visible dust appears on surfaces, the surfaces within the enclosure must be cleaned by wiping with a wet sponge, brush, or cloth and then vacuumed with a HEPA vacuum. All surfaces within the How To Remove Asbestos Pipe Insulation enclosure should be cleaned before the exhaust ventilation system is deactivated and the enclosure is disassembled. 

An approved encapsulant may be sprayed onto areas after the visible dust has been removed. The following How To Remove Asbestos Pipe Insulation organizations provide smoking cessation information. 1. The National Cancer Institute operates a toll-free Cancer Information Service (CIS) with trained personnel to help you.
