Airborn Contaminant Survey

By conducting air monitoring activities, airborne contaminants can be qualified in order to select or confirm exposure control measures. Chemicals and particulates in the workplace. can pose acute and chronic health hazards to workers. Compliance with specific standards is mandatory for businesses and manufactures in order to prevent overexposure. We help companies develop monitoring plans, implement best practices, conduct monitoring, and understand how the results will affect their operations. We are able to help you meet the monitoring requirements for your specific industry.

Noise Control Surveys

We offer noise surveys and studies for determination of Occupational Safety and Health Administration (OSHA) noise limit compliance in the workplace.  The OSHA noise Limits permit employees to be exposed to an average noise level of up to 90 dBA during an 8-hour working day. for an 8-hour exposure of 85 dBA, precautions are required to protect employees, including a hearing conservation program and noise monitoring program. OSHA Regulations permit assessment of noise levels in two ways: 

  • Personal sampling using sound of dosimeters attached to employees. This technique is generally used when workers have high mobility and are exposed to varying noise levels.

  • Area sampling with the use of sound level meters to measure noise in work areas. the noise exposure of workers is calculated based on the time spent in the areas measured.
