Understanding and Managing Exposure to Volatile Organic Compounds in the Workplace


Within the domain of occupational hygiene, employers face a critical challenge in controlling exposure to hazardous substances. Volatile Organic Compounds (VOCs) constitute a class of chemicals that present a particular risk due to their ability to become airborne as vapours at room temperature. As an employer, it is imperative to comprehend the nature of VOCs, the industries or processes where exposure can occur, the associated health effects, and, most importantly, how to prevent or mitigate exposure effectively.

What are Volatile Organic Compounds (VOCs)?

Volatile Organic Compounds encompass a diverse range of chemicals that easily evaporate into the air. These compounds are prevalent in various industrial processes and products, making them a significant concern for occupational health and safety. Common VOCs include toluene, styrene, acetone, ethyl acetate, dimethylformamyde, glycol ethers, benzene, and xylene.

Industries and Processes at Risk

VOCs find their way into the workplace through a multitude of industries and processes. Employers must be particularly vigilant in sectors where the following products are commonly used:

Adhesives (Toluene, Styrene): Found in the manufacturing and construction industries, these compounds are integral to adhesive formulations, posing a risk to workers involved in bonding processes.

Solvents (Acetone, Ethyl Acetate): Industries such as printing, painting, and cleaning extensively use solvents, putting workers in these fields at a higher risk of VOC exposure.

Paints (Dimethylformamyde, Glycol Ethers): Paint manufacturing, automotive painting, and construction activities involve the use of paints containing VOCs, making it crucial to address exposure risks.

Cleaning Agents (Benzene, Xylene): Workers involved in cleaning operations, particularly in industries such as hospitality and healthcare, may face exposure to VOCs present in cleaning agents.

Health Effects of VOC Exposure

Exposure to VOCs can have detrimental effects on the health of workers. Short-term exposure may cause irritation of the eyes, nose, and throat, while long-term exposure can lead to more severe conditions such as damage to the liver, kidneys, and the central nervous system. Some VOCs are also known to be carcinogenic, underscoring the importance of stringent control measures.

Preventing and Reducing Exposure

As an employer, adhering to the Control of Substances Hazardous to Health Regulations 2002 (COSHH) is paramount. Here are key steps to effectively manage and reduce VOC exposure:

Identification of Hazardous Substances: Begin by reviewing safety data sheets for all substances used or worked upon in the workplace. Identify and document all VOCs present.

Exposure Testing Regime: Implement an exposure testing regime to assess the levels of VOCs in the workplace. This involves measuring exposure against Workplace Exposure Limits (WELs) defined by the Health & Safety Executive.

Control Measures: Based on the exposure assessment, take necessary actions to either reduce or control exposure. This may include implementing engineering controls, such as ventilation systems, or providing personal protective equipment.

Ongoing Monitoring: VOC exposure is dynamic, and workplace conditions may change. Establish an ongoing monitoring regime to ensure that control measures remain effective and to promptly address any emerging risks.


In conclusion, understanding and managing exposure to VOCs in the workplace is a fundamental aspect of ensuring the health and safety of employees. Employers play a crucial role in implementing robust control measures, conducting regular assessments, and staying abreast of regulatory requirements to create a work environment that minimises the risks associated with volatile organic compounds. Prioritising the well-being of workers not only fosters a safer workplace but also contributes to long-term productivity and success.
