The Role of the Industrial Hygiene Intern
By Ikwon J.
According to the Occupational Safety and Health Administration (OSHA), industrial hygienists use monitoring and analytical methods to measure worker exposure from environmental hazards and apply strategies including engineering, work practice controls, and other methods to control potential health hazards. This description describes the exact tasks I am performing as the Industrial Hygiene (IH) intern for the City of Seattle.
Primary tasks as the IH intern include understanding the exposure of workers to environmental hazards such as noise, air, or dust. First, a goal of noise monitoring is to prevent hearing loss of workers because extensive exposure to loud noises can negatively affect hearing and may cause hearing loss. Therefore, IH personnel try to reduce the exposure to protect hearing of workers.
Second, air monitoring is conducted, mostly for office workers because they spend eight to ten hours in offices every day. Therefore, poor indoor air quality can be very hazardous. For example, the presence of molds, high concentration of carbon dioxide or carbon monoxide, and dust can be issues regarding indoor air quality. Thus, the industrial hygienist uses analytical methods to detect health hazards in air and applies methods to improve indoor air quality to promote health of office workers.
Lastly, dust sampling may be conducted for indoor air quality for office workers, but it is more focused on protecting construction workers. For instance, silica dust is a basic component of soil, sand, granite, and many other materials and is classified as the human lung carcinogen. Because silica dust is very dangerous and commonly exists in many construction sites, IH personnel monitor silica exposure of workers, and they apply control methods to reduce health hazards.
After the sampling, the industrial hygienist writes a report about findings from the samplings and recommendations to protect health of workers from environmental hazards in work sites. The recommendations may include an engineering control to remove a source of hazard or advising safer work practices.
In conclusion, the Industrial Hygiene tasks are a mixture of field work and office work. On some days, the industrial hygienist conducts sampling and monitoring in the field, but some days they need to stay at in their offices to write reports and perform office tasks as the industrial hygienist. Because the tasks are well balanced between field and office, the career of industrial hygienist is interesting and enjoyable.
