Workplace Exposure Monitoring
In the workplace it is not uncommon to find noise, dust, vibration hazards and, in general, working conditions that can negatively affect the health of employees. It is therefore essential to identify, quantify, and control physical, chemical, and biological risk factors to ensure a healthy and productive working environment.
Our OH&S consultants undertake the appropriate workplace exposure monitoring, tests, and sample analyses to establish fitting preventive measures and controls. Exposure and risk assessments are done using certified instrumentation, which includes direct-reading instruments, sampling pumps, and stationary monitoring devices, among others. Our direct-read instruments give immediate data, and include indicators such as gas detector tubes and electronic devices such as gas monitors and particle counters.
The firms’ workplace exposure monitoring briefs are backed by our OH&S corporate license and our licensed professionals. Currently we perform the following exposure monitorings:
- Acoustic measurements: Noise level monitoring in the workplace is done using sound level meters, which enable us to undertake noise pollution studies to quantify different sorts of noise, primarily industrial, aircraft and mining noise. The IEC 61672-1:2012 is the international standard that establishes the sound level meter functionality and performance, which we use to define any engineering controls and personal protective equipment (PPE) for workers that may be required.
- Illuminance: We monitor light levels at facilities using light level meters as per standard test methods. Our consultants carry out illumination studies and risk assessments in order to recommend the right level of light comfortable for a person in an office, manufacturing or production area, and improve employees' safety. Thus appropriate recommendations are provided for the areas where low lux is observed.
- Gases and organic vapors: Gas monitoring and testing must be part of any safety procedure where there is a potential exposure to hazardous atmospheres. For organic vapors and gases, solid sorbent sampling tubes are used with charcoal and other sorbents. We monitor gases and organic vapors in the work environment by collecting samples and analyzing them, taking into account the appropriate occupational hygiene protocols with the aim of establishing the presence of gases, such as carbon monoxide (CO), hydrogen sulfide (H2S), oxygen (O2) and the lower explosive limits (LEL) of combustible gases.
- Thermal comfort: The firm helps our clients manage the temperature in their workplace in order to guarantee the thermal comfort of employees. We use the instruments required for this type of measurements (i.e. dry-bulb and wet-bulb thermometers, as well as tools for measuring air speed) in order to determine whether the temperature and thermal comfort are suitable. If the measurements are outside the comfort zone, control measures, such as local heating or cooling, heating systems, and additional facilities, e.g. cold water dispensers, may be required.
- Particulates: For particulates, polyvinyl chloride (PVC) filters are used for sample collection in order to undertake gravimetric analyses. Based on the measurements made and the tolerance margins and permissible limits, reduction targets are set so that particulates do not have harmful effects on the health of coworkers, primarily with regards to their respiratory system. Our sampling distinguishes between total, inhalable, and thoracic dust.
- Non-ionizing radiation: Monitoring of non-ionizing radiation is done by identification of the hazard and assessment of the associated risk. Whenever necessary, electric fields, magnetic fields and power are measured. We ensure employers identify and label all sources of electro-magnetic radiation (EMR) and monitoring of emissions and checks on workers' exposure levels are undertaken. If it is deemed to be required, we introduce measures to reduce electromagnetic field (EMF) exposures, such as labeling existing sources of EMR, grounding sources of electrical fields, shielding UV sources by glass filters, and use of lower EMF designs, etc.
