HES is a professional occupational and environmental health and safety consulting firm experienced in all aspects of asbestos and lead hazard management and abatement activities.  HES has in-house capabilities to conduct surveys and field site assessments for the identification of asbestos and lead containing materials.

Our staff can help develop and implement an appropriate field sampling strategy and record keeping system in order to collect representative and sufficient bulk samples to determine the presence of asbestos/lead containing materials within the facility/area.  HES has conducted inspections and designed abatement projects in accordance with applicable regulations such as Asbestos Hazard Emergency Response Act (AHERA), and U.S. Department of Housing and Urban Development (HUD).

Determination of the extent of airborne fiber/contaminant workplace exposure levels can be accomplished through collection of representative area and personal air samples.

Review of all analytical results obtained from the collected samples helps to determine the extent of exposure hazard from asbestos/lead containing materials, and provide recommendations of the most reasonable and cost effective methods for asbestos/lead hazard control. 

Analysis of samples for asbestos is conducted by NVLAP accredited and TDH licensed laboratories using Polarized Light Microscopy (PLM) in compliance with guidelines established by the US EPA (40CFR Part 763.115).

The NITON XL Model 309 portable X-Ray Fluorescence instrument is used to test for lead-based paint coatings in the field.

Bulk sample analysis for lead is performed at an ELPAT accredited laboratory using approved methods such as USEPA 7420, 6010, 7082 and 600/8-91-213.

Exposure assessment reports are prepared after reviewing results of the asbestos/lead hazard assessment survey.  Technical specifications are prepared for the execution of identified asbestos/lead hazard abatement work if required.  Additionally, HES can assist the owner in pre-qualifying and selecting abatement contractors.

Once a project is initiated, HES can provide continuous inspection and monitoring of the contractor=s performance in accordance with the project specifications (e.g. airborne emissions, standard operating procedures, respiratory protection practices, and waste handling and final disposal). HES inspects the work area after abatement and conducts clearance testing prior to re-occupancy.  The work area is released only after both visual inspection and air monitoring has determined compliance with the specified job clearance standards.

Finally, HES supplies a final project report to the Owner which certifies contractor compliance with the project specifications and final airborne fiber/contaminant levels.

If warranted we can assist in the development and implementation of an appropriate Operations and Maintenance (O&M) program for facilities with asbestos-containing materials which will remain in place.
