Industrial, construction and abatement activities often result in excessive noise levels.  Noise levels can also be an issue near sensitive areas such as hospitals, schools and daycares.  But what is excessive when it comes to noise?  Regulatory agencies define a noise Exposure Limit for unprotected persons based on duration and intensity.  Peak technicians monitor decibel levels emitted during a work activity and compare the results to local regulatory limits.

Air Clearance

An air clearance is required upon completion of various asbestos, lead and mould removal projects before remediated area can be released to other trades or unprotected persons. As with air monitoring, air clearance sampling is sometimes performed to satisfy internal OH&S requirements or to alleviate staff exposure safety concerns.

Visual Clearance

A visual clearance inspection is required to confirm the removal of all hazardous materials following abatement activities, prior to re-occupancy or demolition.  Regulatory authorities required third-party clearance inspections be performed by persons with detailed knowledge of the scope of the project and the hazardous materials being abated.

Air monitoring during a hazardous materials abatement project is required under certain circumstances such as during the high risk removal of asbestos containing materials.  Even when the work isn’t considered a high risk, some clients opt for air monitoring to comply with their internal OH&S requirements or to reassure staff in the case of safety concerns. Air monitoring is also used to compile historical data regarding the release of fibres or dust during various work procedures. Examples include: asbestos fibre release while breaking floor tiles from concrete, lead dust release when grinding paint with a specific lead concentration or release of silica dust while cutting concrete. 

Data collected from such work activities are then compared to regulatory exposure limits. These data points are also relied upon in the evaluation of safe work procedures and protective equipment efficacy.
