Aug
Potassium hydroxide (KOH) is an important chemical in many industries, but it also poses many risks to worker health. This article will explore the health effects of KOH when working in manufacturing plants, along with the necessary protective measures to ensure safety.
1. What is Potassium hydroxide?
Potassium hydroxide, with the chemical formula KOH, is a chemical compound belonging to the alkali group. It is commonly known as caustic potash. KOH is a white crystalline solid and is very soluble in water, forming a strong alkaline solution.
KOH has highly corrosive properties and is one of the strongest bases used in industrial applications. In a moist environment, it can absorb moisture from the air, causing caustic potash pellets to quickly become wet and sticky. This compound is primarily produced by the electrolysis of potassium chloride (KCl) solution or potassium carbonate (K2CO3) to obtain potassium hydroxide.
KOH has many applications in industry, including the production of soap, detergents, catalysts in chemical reactions, and in food processing. However, due to its strong corrosive nature, it must be handled carefully to avoid harm to health and the environment.
Understanding the characteristics and properties of potassium hydroxide not only helps in its effective application but also serves as an important basis for ensuring safety when working with this chemical in manufacturing plants.

2. Where does Potassium hydroxide originate from in the production process?
Potassium hydroxide (KOH) originates from various industrial processes. In the chemical manufacturing industry, KOH is often produced through the electrolysis of potassium chloride (KCl) or potassium carbonate (K2CO3) solutions. This is the most common method, where the electrolysis of potassium chloride solution separates it into potassium hydroxide and chlorine gas. This chemical can be recovered in solution or solid form depending on the production process requirements.
Additionally, in soap manufacturing plants, KOH also arises as a byproduct during the reaction between fats and alkaline solutions. In this process, fats or oils react with KOH solution to form soap and glycerin. Excess or unreacted KOH may remain in the final product or must be properly treated.
Besides, KOH also appears in food processing, especially when producing products that require pH adjustment. For example, in the food processing industry, KOH may be used to clean or adjust the pH of raw materials. In these processes, KOH is added in solution or powder form, and its presence can create ammonia gas and other byproducts.
These sources indicate that potassium hydroxide is widely present in many production fields, from chemicals to food, and managing and controlling its generation is crucial to ensure safety for workers and the working environment.
3. Industries that use Potassium hydroxide in production
Potassium hydroxide (KOH) is an important chemical widely used in many industries and production fields. One of the main industries using KOH is soap production. In the soap manufacturing process, KOH is used to react with fats or oils to form soap and glycerin. Soap produced from KOH typically has properties that make it easily soluble in water and is used in liquid soap products and detergents.
The chemical industry is also a significant field that uses KOH. This chemical is used as a catalyst in many chemical reactions and in the production processes of other chemicals. KOH helps adjust the pH of solutions and promotes the necessary chemical reactions to create other chemical products.
In the food industry, KOH is used to adjust pH and clean processing equipment. It plays an important role in maintaining product quality and ensuring efficient food processing operations. However, the use of KOH in food must be strictly controlled to ensure consumer health safety.
The wastewater treatment industry also uses KOH to adjust pH and remove impurities. KOH helps treat wastewater by neutralizing acids and purifying water before it is discharged into the environment or reused.
In addition, KOH is also used in battery production, especially alkaline batteries, where it is used as a key component in electrolyte solutions. It also plays an important role in the paper and pulp industry, where it is used to process and clean raw materials.
The widespread applications of potassium hydroxide demonstrate its important role in many production fields. However, the use of KOH must be carefully managed to avoid health and environmental risks.
4. How does Potassium hydroxide affect workers
Potassium hydroxide (KOH) is a powerful chemical and can significantly affect worker health if not used and managed properly. Due to its highly corrosive nature, KOH can cause severe damage to the skin, eyes, and respiratory system.
When in direct contact with the skin, KOH can cause severe burns and irritation. If not treated promptly, chemical burns can lead to serious injuries and leave long-term scars. Workers in environments with high KOH concentrations must use personal protective equipment such as chemical-resistant gloves and clothing to minimize exposure risk.
If KOH comes into contact with the eyes, it can cause severe irritation, redness, pain, and even corneal damage. In case of eye contact, rinse immediately with clean water and seek emergency medical care. KOH can damage eye structures and have long-term effects on vision if not treated promptly.
Inhaling KOH dust or vapor can cause respiratory irritation, leading to coughing, difficulty breathing, and respiratory problems. In workplaces where KOH is present, providing adequate ventilation and using protective masks is crucial to protect workers’ respiratory health.
In addition to direct effects on the skin, eyes, and respiratory tract, KOH can also cause health problems if not handled properly in the workplace. Long-term exposure to KOH can lead to chronic health issues and reduce the quality of life for workers.
5. Safe permissible concentration of Potassium hydroxide for human exposure
To ensure worker safety when exposed to potassium hydroxide (KOH), controlling the concentration of this chemical in the work environment is very important. Occupational safety and health regulatory agencies, such as the Occupational Safety and Health Administration (OSHA) and the World Health Organization (WHO), have established limits on KOH concentration to protect worker health.
The safe concentration of KOH in the workplace is typically specified in air quality and chemical concentration standards. According to current regulations, the maximum permissible concentration of KOH in workplace air usually does not exceed 2 mg/m³ over an 8-hour workday. This limit is determined based on KOH’s potential to cause irritation and health effects in humans.
Maintaining KOH concentration below the specified level not only helps minimize the risk of skin, eye, and respiratory irritation but also helps prevent chronic health problems related to long-term exposure to this chemical. Control measures such as effective ventilation systems, use of personal protective equipment, and safe work procedures are necessary to maintain KOH concentration within permissible limits.
In addition to controlling air concentration, regular health monitoring for workers exposed to KOH is also an important part of the safety management program. This includes checking relevant health indicators and implementing timely treatment measures if there are signs of poisoning or irritation.
To ensure compliance with safety standards, companies need to conduct regular checks and measurements of KOH concentration, while also staying updated on the latest regulations and standards from authorities. Full implementation of protective and monitoring measures will help ensure worker safety and maintain a healthy working environment.
At a basic level, if working in an industrial environment, adhering to safety standards and limiting exposure to Potassium hydroxide is important. Organizations like the Occupational Safety and Health Administration (OSHA) in the United States provide guidelines and safety principles to protect workers from the negative impacts of chemical substances.
