Chemical hazards related to dangerous goods or hazardous substances are frequently investigated by occupational hygienists. Other related areas including indoor air quality IAQ and safety may also receive the attention of the occupational hygienist.

Biological hazards may stem from the potential for legionella exposure at work or the investigation of biological injury or effects at work, such as dermatitis may be investigated.

As part of the investigation process, the occupational hygienist may be called upon to communicate effectively regarding the nature of the hazard, the potential for risk, and the appropriate methods of control.

Appropriate controls are selected from the hierarchy of control : by elimination, substitution, engineering, administration and personal protective equipment PPE to control the hazard or eliminate the risk. Such controls may involve recommendations as simple as appropriate PPE such as a 'basic' particulate dust mask to occasionally designing dust extraction ventilation systems, work places or management systems to manage people and programs for the preservation of health and well-being of those who enter a workplace.

Examples of occupational hygiene include: Disposable foam earplugs: out of the ear with coins for scale top and inserted into the wearer's ear bottom. Developing plans and procedures to protect against infectious disease exposure in the event of a flu pandemic. Monitoring the air for hazardous contaminants which may potentially lead to worker illness or death.

Workplace assessment methods[ edit ] Although there are many aspects to occupational hygiene work the most known and sought after is in determining or estimating potential or actual exposures to hazards. For many chemicals and physical hazards, occupational exposure limits have been derived using toxicological, epidemiological and medical data allowing hygienists to reduce the risks of health effects by implementing the "Hierarchy of Hazard Controls".

Several methods can be applied in assessing the workplace or environment for exposure to a known or suspected hazard. Occupational hygienists do not rely on the accuracy of the equipment or method used but in knowing with certainty and precision the limits of the equipment or method being used and the error or variance given by using that particular equipment or method. Ignacio and William H.

A traditional method applied by occupational hygienists to initially survey a workplace or environment is used to determine both the types and possible exposures from hazards e.

The walk-through survey can be targeted or limited to particular hazards such as silica dust, or noise, to focus attention on control of all hazards to workers. A full walk-through survey is frequently used to provide information on establishing a framework for future investigations, prioritizing hazards, determining the requirements for measurement and establishing some immediate control of potential exposures.

Other sources of basic characterization information include worker interviews, observing exposure tasks, material safety data sheets, workforce scheduling, production data, equipment and maintenance schedules to identify potential exposure agents and people possibly exposed. The information that needs to be gathered from sources should apply to the specific type of work from which the hazards can come from.

As mentioned previously, examples of these sources include interviews with people who have worked in the field of the hazard, history and analysis of past incidents, and official reports of work and the hazards encountered. Of these, the personnel interviews may be the most critical in identifying undocumented practices, events, releases, hazards and other relevant information.

Once the information is gathered from a collection of sources, it is recommended for these to be digitally archived to allow for quick searching and to have a physical set of the same information in order for it to be more accessible. One innovative way to display the complex historical hazard information is with a historical hazards identification map, which distills the hazard information into an easy to use graphical format.

An occupational hygienist may use one or a number of commercially available electronic measuring devices to measure noise, vibration, ionizing and non-ionizing radiation, dust, solvents, gases, and so on. Each device is often specifically designed to measure a specific or particular type of contaminant.

Such devices are often subject to multiple interferences. Electronic devices need to be calibrated before and after use to ensure the accuracy of the measurements taken and often require a system of certifying the precision of the instrument. Dust sampling[ edit ] Nuisance dust is considered to be the total dust in air including inhalable and respirable fractions. Various dust sampling methods exist that are internationally recognised.

Inhalable dust is considered to be dust of less than micrometers aerodynamic equivalent diameter AED that enters through the nose and or mouth. See Lungs Respirable dust is sampled using a cyclone dust sampler design to sample for a specific fraction of dust AED at a set flow rate.

The respirable dust fraction is dust that enters the 'deep lung' and is considered to be less than 10 micrometers AED. Nuisance, inhalable and respirable dust fractions are all sampled using a constant volumetric pump for a specific sampling period.

By knowing the mass of the sample collected and the volume of air sampled, a concentration for the fraction sampled can be given in milligrams mg per metre cubed m3. From such samples, the amount of inhalable or respirable dust can be determined and compared to the relevant occupational exposure limits. By use of inhalable, respirable or other suitable sampler 7 hole, 5 hole, et cetera , these dust sampling methods can also used to determine metal exposure in the air.

This requires collection of the sample on a methyl-cellulose ester MCE filter and acid digestion of the collection media in the laboratory followed by measuring metal concentration though an atomic absorption or emission spectrophotometry.

A further method exists for the determination of asbestos, fibreglass, synthetic mineral fibre and ceramic mineral fibre dust in air.

This is the membrane filter method MFM and requires the collection of the dust on a grided filter for estimation of exposure by the counting of 'conforming' fibres in fields through a microscope. Drama Fiction Non-fiction Poetry. Epidemiology Chapter 1: Basic Epidemiologic Concepts and Principles.
