Occupational Air and Noise Monitoring

The law requires employers to carry out risk assessments on agents in the workplace which may cause adverse health effects to their employees, including the new Safety, Health and Welfare at Work (General Application) Regulations 2007.

Occupational Monitoring

Fitz Scientific monitor for all substances listed on the Health and Safety Authority (Chemical Agents Regulations) 2007 Code of Practice as well as the HSA's EH40 Workplace exposure Limits. Our highly qualified team calculate the exposure, which can then be compared to national standards set by the Health & Safety Authority

occupational air, noise and dust monitoringMonitoring can be conducted to determine STEL as well as 8-hour TWA exposure.

We also offer the following:

  • Asbestos monitoring
  • Advice on control of respiratory sensitizers and allergens  
  • Indoor air quality investigations for Workplaces, places of Entertainment and Learning Institutes (schools, lecture halls etc.)

Occupational Noise Monitoring

Fitz Scientific have a dedicated, highly experienced team to undertake all manner of occupational noise surveys. Employees in the nightclub and music industry, construction industry, textiles, metalworking, forestry and agriculture, those using grinders, chainsaws, woodworking machinery, tractors or other noisy machinery are all at risk of exposure to high levels of occupational noise. Legislation currently available to protect workers from noise exposure includes:

  • European Communities (Protection of Workers) (Exposure to Noise) Regulations 1990 (SI No. 157 of 1990)
  • Council Directive 86/188/EEC on the protection of workers from the risks related to exposure to noise at work
  • Directive 2003/10/EC on the minimum health and safety requirements regarding the exposure of workers  to the risks arising from physical agents (noise)
  • Directive 98/37EC on the approximation of the laws of the Member States relating to machinery contains essential health and safety requirements for machinery safety.

Services available at Fitz Scientific include:

  • Assessment of Broadband and 1:3 Octave frequency measurements
  • Assessment of tonal components in occupational noise sources
  • Interpretation of results in accordance with Regulations
  • Advice and recommendations on reduction of occupational noise levels

Occupational Air Monitoring

Fitz Scientific has over ten years experience in the area of occupational air monitoring. We offer tailor made, comprehensive packages to cater for all monitoring and analysis required by legislation for hospitals, clinics, dental surgeries and other healthcare/ commercial facilities.

Anaesthetic gases:

Trace levels of anaesthetic gases in operating rooms and other areas of healthcare facilities can result from equipment leaks, anaesthetic technique, exhalation of residual gases by patients and waste gases.

Gases are frequently used as an anaesthetic in operating rooms, emergency rooms, or inpatient settings. Low levels of this chemical have been associated with central nervous system, cardiovascular, and reproductive effects in humans along with a decrement in audiovisual performance. The Health and Safety Authority (Chemical Agents Regulations) 2007 Code of Practice specifies an 8-hour TWA limit of 30 mg/m3 and a STEL (15 minute reference period) of 45 mg/m3 for certain anaesthetic gas.

Halogenated anesthetic gases are also frequently administered. These compounds can cause eye, nose, and throat irritation. In addition, chronic exposure to halogenated anesthetic gases has been linked to an increased risk of reproductive hazards along with hepatic and renal disease. The Health and Safety Authority (Chemical Agents Regulations) 2007 Code of Practice specifies an 8-hour TWA limit for anesthetic gases.

Occupational Noise Monitoring
Sterilant gases:

Ethylene oxide is routinely used in healthcare facilities to sterilize medical devices and equipment. The Health and Safety Authority (Chemical Agents Regulations) 2007 Code of Practice specifies an 8-hour TWA limit of 10 mg/m3 for ethylene oxide.

Solvents and Disinfectants:

Glutaraldehyde is used in health-care settings as a cold sterilant to clean heat sensitive equipment. The Health and Safety Authority (Chemical Agents Regulations) 2007 Code of Practice specifies an STEL (15 minute reference period) limit of 0.2 mg/m3 for glutaraldehyde.

Formaldehyde is a chemical agent most commonly used in health-care facilities to fix and preserve tissue. The International Agency for Research on Cancer (IARC) classifies formaldehyde as a human carcinogen. The Health and Safety Authority (Chemical Agents Regulations) 2007 Code of Practice specifies an 8-hour TWA limit of 2.5 mg/m3 and an STEL (15 minute reference period) limit of 2.5 mg/m3 for formaldehyde.


Ambient dust in the workplace from processes carried out can often times be excessively high. Employees operating in such areas can experience health effects such as lung capacity deterioration and other such ailments. For this reason dust concentrations should be monitored to ensure either they are in compliance with maximum dust concentrations recommended by the HSA, or that in areas of high dust concentrations personnel face masks are supplied to the employees.

Inhalable dust is taken to mean any solid particle which by its small size can be carried in airflow or remains airborne. It includes respirable dust. Respirable dust is taken to be the solid particles of less than 8.5 microns in size. Dust of this size is normally invisible to the human eye. Respirable dust can get deep into the lung and does not get ejected by the normal means of breathing out, coughing or travelling out in the mucus.

Occupational Dust MonitoringFitz Scientific conducts occupational dust and dust fraction monitoring according to HSE MDHS 1 4/3 (General methods for sampling and gravimetric analysis of respirable and Inhalable dust). Fitz scientific has experience in undertaking occupational dust monitoring in a range of work environments providing clients with information to assess the health risks of dust in the workplace.

Services offered include:

  • Personal sampling attachment of sampler to the breathing zone of personnel working in the dust prone area.
  • Background sampling and fixed point sampling used to determine the levels of dust in the work
