The telecommunication industry contains includes cable providers, internet service providers, satellite providers and telephone providers and confined spaces. Even simple above ground termination boxes may contain gas hazards generated from the cable runs underground. Gases such as methane, carbon dioxide and hydrogen sulphide can run through cable trunking accumulating in termination boxes and manifesting as hazards when the termination box is opened.
The risk of danger occurs when a worker is sent to carry out tasks involving opening up of enclosed volumes that may not have been accessed for a period of time. All telecommunications companies have these in abundance.
What are the Dangers?
Those working in the telecommunications industry are at risk from a variety of gaseous dangers, many of which could cause harm to their health and safety. Though less obvious, these risks should be taken as seriously as falls from heights or electrocution, and they require a similar level of training. A worker must not climb to an elevated position without a harness, similarly they shouldn’t be accessing confined spaces without appropriate confined space training. Awareness of the dangers present and minimising the risks that could lead to adverse effects is a well-known safety principle. Training and proper PPE can help protect workers from these hazards.
Gas Hazards and Risks
As there are many confined spaces in the telecommunication industry workers are at risk from the presence of hazardous and toxic gases there. Hazardous gases can also be linked to seemingly simple above-ground termination boxes. Gases such as methane, carbon dioxide and hydrogen sulphide sometimes travel through the cable trunking, and therefore, when the termination box is opened, a build-up of these gases can be released.
Enclosed or partially enclosed spaces with high levels of methane in the air reduce the amount of oxygen available to breathe and therefore can cause mood changes, speech and vision problems, memory loss, nausea, sickness, facial flushing and headaches. In more severe cases and prolonged exposure, there may be changes in breathing and heart rate, balance problems, numbness, and unconsciousness. There is also a risk of fire as methane is highly flammable.
Carbon monoxide (CO) consumption also poses serious health issues to workers, with those ingesting the toxic substance facing flu-like symptoms, chest pain, confusion, fainting arrhythmias, seizures, or even worse health effects for high or long lasting exposures. Hydrogen sulphide (H2S) poisoning causes similar issues, as well as delirium, tremors, convulsions, and skin and eye irritation. Carbon dioxide is an asphyxiant gas that can displace oxygen and hance dizziness.
Gas detection can be provided in both fixed and portable forms. Our portable gas detectors protect against a wide range of gas hazards, these include Tetra 3 and T4. Our fixed gas detectors are used where reliability, dependability and lack of false alarms are instrumental to efficient and effective gas detection, these include Xgard and Xgard Bright. Combined with a variety of our fixed detectors, our gas detection control panels offer a flexible range of solutions which are able to measure flammable, toxic and oxygen gases, report their presence and activate alarms or associated equipment, for the telecommunication industry our panels include Gasmaster.
