Consider Your Current Workplace Or A Workplace With Which You Are Fami

Consider your current workplace or a workplace with which you are familiar. Of the three primary routes of exposure (inhalation, dermal, ingestion), which route do you believe is the most important for controlling exposures to health hazards? Give an example of a health hazard in the workplace, and explain why you believe the exposure route you chose is important for that health hazard. (Note: By a hazard in the workplace , we mean a chemical hazard, so name the chemical. Also, name the process the chemical will be working in. Then determine the various routes of potential exposure. You may also comment on the target organ or systemic effects). Assume that your input will be an informed opinion so expect to see in-text citations and reference sources used (as you would for any academic writing) unless you are the expert who wrote the article or book on the subject. Even then, it is a good idea to provide resources for the reader to be aware of-Dr.B. Please include the name of the person or question to which you are replying in the subject line. For example, "Tom's response to Susan's comment." ALSO PLEASE REPLY TO ANOTHER STUDENTS COMMENT BELOW Michael: One thing that jumps right out at me is when my tile guys do large commercial projects. There are two hazards that jump out to me. One is that they stack tiles in what could be considered walk ways and the major hazard is that they use a material called Mastic to seal the tile to the floor. Per Merriam Webster dictionary, Mastic is one of any various pasty materials used as protective coatings or cements in the placing of ceramic tile or other materials. This chemical could be either exposed through dermal, coming in contact with the skin when the tiler is putting down the tile if they try to cut safety corners and not wear gloves or they can enter the body through Inhalation because they are working so close to the chemical while the work in being performed. The mastic does give off a smell in which vapors are being put in the air at a small level but over time could be dangerous to the tiler if they do not wear proper PPE. P4 Introduction to Industrial Hygiene state's that Powders or dusts in the work environment can also be a form of exposure when they come in contact with the skin. This would also be the case with tiling as there are dust particles even after the job is done that must be swept up during the cleaning process that could enter through mouth Injestion.

In occupational health and safety, understanding the primary routes of exposure to chemical hazards is crucial for effective risk management and the implementation of protective measures. Among inhalation, dermal contact, and ingestion, inhalation is often regarded as the most critical route for controlling exposures to airborne chemical hazards due to the respiratory system's direct access to the bloodstream and the frequent presence of airborne contaminants in various work environments. This paper explores this concept through the example of a chemical used in a construction setting—mastic adhesive—and discusses its associated health hazards, exposure routes, and systemic effects.

Mastic adhesives, commonly employed in floor tiling, are composed of complex chemical formulations, including volatile organic compounds (VOCs) such as toluene, xylene, and formaldehyde (Agency for Toxic Substances and Disease Registry, 2011). These chemicals are released into the air as vapors during application and curing, posing inhalation risk to workers involved in tiling projects. Since tilers work in close proximity to the adhesive, inhalation becomes the primary route of exposure, especially if proper respiratory protective equipment (RPE) is not used. Persistent inhalation of VOCs can lead to various health issues, including respiratory irritation, central nervous system depression, and systemic toxicity (Snyder et al., 2017).

The target organs affected primarily include the lungs, brain, and liver, which are involved in detoxification and metabolic processing of chemical toxins. Long-term exposure to VOCs from mastic may cause chronic respiratory diseases, neurotoxicity, and even carcinogenic effects, as some VOCs are classified as carcinogens (International Agency for Research on Cancer, 2012). The systemic absorption of these chemicals through inhalation allows them to reach various organs, impairing their function and leading to adverse health outcomes.

While dermal contact is also a concern, especially during mixing or accidental spills, it generally poses a secondary route of exposure in comparison to inhalation in this scenario. Proper personal protective equipment, including gloves and coveralls, can mitigate dermal absorption; however, vapors in the air often penetrate protective clothing, making inhalation control measures more critical. Ingestion of chemical residues is less likely during typical tiling operations but can occur from contaminated hands or food consumed in the work area, emphasizing the importance of hygiene practices.

Controlling inhalation exposure involves multiple strategies such as adequate ventilation, use of RPE, and substitution of less hazardous materials when possible. Engineering controls are essential in capturing vapors at the source, especially in enclosed or poorly ventilated spaces (National Institute for Occupational Safety and Health, 2015). Administrative controls, including worker training and strict hygiene practices, further reduce risks. Personal protective equipment serves as the last line of defense but must be properly fitted and used consistently.

In conclusion, inhalation stands out as the primary route for exposure to chemical hazards like mastic adhesives in construction settings due to the volatility of the chemicals involved and the proximity of workers to vapors. Effective control of inhalation exposure is paramount to safeguarding workers' health, preventing acute and chronic health effects, and reducing occupational disease burden. Implementing a comprehensive hazard control plan that integrates engineering, administrative, and personal protective measures is essential for managing chemical exposures in the workplace (Leigh et al., 2016).
