Halogens and Health: A Look at the Risks.
Comprising group 17 of the periodic table, halogens are oxidising and electrophile agents with various commercial and industrial uses. Along with their other uses, halogens, specifically chlorine, bromine, and fluorine are commonly used in cable manufacturing as they are incorporated into materials like polyvinyl chloride (PVC) and flame retardants to enhance the performance and safety of cables. However, exposure to cables containing halogens can also threaten human health and the environment.
This blog aims to provide a layered overview of exposure to halogens and how they could lead to several diseases in humans while also contaminating the atmosphere with toxic chemicals.
Types of Halogens and their uses
Fluorine (F) The most reactive of all halogens, this gas is pale yellow and used in welding and glass frosting in the form of fluorides. It is also utilised in nuclear power plants to separate isotopes of uranium.
Chlorine (Cl) This is a greenish-yellow gas used as a disinfectant to kill bacteria and purify drinking water and swimming pools. It is also used in the production of various chemicals like polyvinyl chloride (PVC), used in making plastic products.
Bromine (Br) Bromine is a reddish-brown liquid that is used in chemicals, dyes, pesticides, medicines, and chemical intermediates. Halon fire extinguishers which are used to put out fires also contain Bromine in them.
Iodine (I) This is a shiny, purple-black solid that is essential for human health, particularly in thyroid function. They are also used in pharmaceuticals and disinfectants, printing inks, and dyes in the form of iodine salts.
Astatine (At) This is a rare and radioactive element which is scarce. It is primarily used in scientific research and cancer treatment.
Halogens in Cable Manufacturing
PVC Cables Polyvinyl Chloride (PVC) is a widely used plastic in cable insulation and sheathing. It contains chlorine that has excellent flame-retardant properties which makes them a popular choice for cables in buildings and industrial applications.
Flame Retardants Since Bromine-based compounds help prevent the spread of fire, they are often used as flame retardants in cables. Fluoropolymers Fluorine with its excellent temperature-resistant, chemical-resistant properties is commonly used in fluoropolymers like polytetrafluoroethylene (PTFE) which makes them ideal for high-performance cables in a vast industry.
Manufacturing Process
Workers who are in charge of cable manufacturing are at constant risk of exposure to halogens and toxic gases through the inhalation of dust or fumes and skin contact with raw materials.
Installation and Maintenance Since installation and maintenance require cutting, stripping, or burning cables, it makes the electricians prone to serious health risks.
Fire Situations During a fire breakout, cables containing halogen can release toxic gases such as hydrogen chloride, hydrogen bromide, and hydrogen fluoride which could further create a contaminated space for the occupants and the firefighters.
Environmental Release Halogen-containing cables must be disposed of properly, otherwise they might lead to the release of harmful and toxic gases, further contaminating the environment.
Health Risks Associated with Halogen Exposure from Cables
Chlorine and PVC Exposure to halogen from burning PVC cables can lead to respiratory issues which could further cause coughing, choking, and lung diseases. Coming in contact with these chemicals can also lead to skin and eye irritation, which includes redness and burning sensations. Even though short-term exposure to these chemicals may be treatable, long-term exposure can result in increased cancer risks.
Bromine-based Flame Retardants Bromine-based halogens can release harmful elements that can cause neurological effects due to their exposure leading to symptoms such as headache, dizziness, and cognitive loss. These retardants, also known as endocrine disruptors, can lead to a dysfunctional reproductive system. Their exposure can cause skin irritation, respiratory problems, and in severe cases, chemical burns.
Fluorine and Fluoropolymers Inhaling these gases can make a person prone to frequent headaches and dizziness in their daily lives. They could also lead to long-term respiratory problems and even pain and damage to bone joints. Too much fluoride in the body can lead to neurotoxic effects further contributing to slow development in children.
Preventing and Managing Halogen Exposure from Cables
Use of Halogen-free cables To avoid these circumstances switch to LSZH cables, which will ensure your safety from inhaling hazardous chemicals as they do not release toxic gases when burned, hence creating a positive and sustainable environment for all of us. They can be utilised in residential, commercial, and industrial buildings as these cables are particularly critical in high-occupancy buildings.
Proper Ventilation Ensuring proper ventilation in your buildings will reduce the contamination of these gases in the air with the help of frequent drainage of these gases. This will help in minimising the inhalation of toxic gases by releasing them through mechanical Ventilation systems, and local exhaust ventilation.
Fire Safety Measures Implementing smoke detection systems will help in preventing damage before looking for a cure. These detectors help in minimising the release of toxic gases by providing an early alert for the people. Installing these detectors along with other safety protocols can significantly help in reducing these incidents and the dangers attached to them.
Conclusion
Halogens play an important role in our everyday lives. While its use cannot go unnoticed, overuse of it can lead to potential health hazards. Understanding and identifying its sources along with following the appropriate measures will help in reducing health risks and damage to the environment.
Industries and other vast businesses should switch to halogen-free cables, for which we recommend Greenbuild Supply. Their wires are designed to excel in heavy-duty applications and for ease of installation, the range of LSZH+ conduits and cable covers offer superior performance, sustainability, and safety. Greenbuild also supplies you with other products that could help you in easy installation of cables based in Australia, including smoke detector systems.
Since prevention is better than cure, contact Greenbuild Supply today and switch to LSZH while allowing yourself to live a comfortable, tension-free, and sustainable life.
