Indoor & outdoor air monitoring

Occupational air monitoring is the monitoring of indoor and outdoor air in the vicinity of the workspace of staff. There are strict legal limits on the concentration of airborne contaminants because these can lead to health problems. The aim of occupational monitoring is to measure these concentrations over a representative pattern of work and determine whether the limits are breached.

Monitoring is typically completed by the use of calibrated air pumps drawing the workplace air through a filter, impinger or sorbent tube. The media is then analysed for the substance being monitored.

Trinitas has years of experience conducting air monitoring activities for a range of dust, fumes and vapours.

  • Air monitoring for hazardous substances can be undertaken to:
  • Ensure exposure levels are below applicable exposure standards
  • Evaluate the exposure of workers to contaminants in the air and consider controls to reduce the hazardous air contaminants
  • Assist management in making the correct decisions in terms of the implementation of suitable control measures where needed
  • Identify indoor air quality levels
  • Determine the effectiveness of control measures such as local exhaust ventilation to reduce or eliminate

Our team of hazardous material specialists carry out air monitoring which can include but is not limited to the following substances:

  • Benzene
  • Isocyanates
  • Asbestos
  • Respirable Crystalline Silica Quartz
  • Inhalable dust
  • Diesel particulate matter
  • Petroleum

Noise Monitoring (Static & Personal)

Noise monitoring is conducted to determine the level of exposure to harmful noise through the use of machines and equipment. The need for noise measurement and controls may have originated from previous audits conducted in the workplace, statutory compliance or redevelopment of noise management plans. Surveys are conducted to:

  • Identify items of equipment and operations which have the potential to cause the exposure standard to be exceeded;
  • Delineate all areas where the average sound level 85dB or the peak noise level exceeds 140 dB
  • Evaluate noise exposures (LAeq,8hr) so that personnel exposed above the exposure standard can be identified; and
  • Assess the adequacy of the noise reduction afforded by personal hearing protectors already in use and of alternative protectors if required.

We can conduct workplace Noise Monitoring using the following 2 methods

  • Sound Level Meter
  • Personal Noise Dosimeters

Onsite Audiometric Assessments

Based in Sydney, Trinitas Group have two mobile hearing test units that can come to your site seven days a week, 24 hours a day. We have a team of qualified Occupational Hygienists (trained against AS/NZS 1269.4:2005 Occupational Noise Management Part 4: Auditory Assessment) who are able to conduct testing across shift lines in the one day. The 2011 WHS Regulations state that:

  • Audiometric testing is required when workers are frequently required to wear Personal Protective Equipment to protect from hearing loss.
  • Workplace audiometric testing is required every 2 years.
  • New employees must be tested within 3 months of commencing employment
  • These workers include plant operators, production line workers, users of noisy power tools, truck drivers, call centre operators, nightclub staff, emergency services workers etc.

We will come to your workplace with our soundproof booth, alleviating the need to send employees off-site, saving considerable costs in time and travel arrangements. We will work with you to help scheduling staff testing and offer a full record management service and recall facility. We’ll record your last round of tests in our database for reference at no additional charge.

Lighting Surveys

Illumination levels can have an adverse impact on employee health and productivity and workplace health and safety. We have been engaged to conduct lighting assessments across many industries including mining, industrial, manufacturing, food processing and offices.

Illumination assessments are carried out by qualified professionals measuring the ‘lux’ or ‘illuminance’ of a site and comparing the results to determine compliance with the recommended levels in Australian Standard 1680.1. Interior Lighting. Our service is delivered to both small and large business across both private and public sectors in the industrial and commercial sectors.
