1070nm laser emissions

Unveiling the risks of open fibre laser cutting machines: Protecting against 1070nm laser emissions and the blink reflex.

Advanced Robotic Technology (ART) is an Australian machine manufacturer and distributor concerned with machine safety. Director David White says, “The huge volume of imported machinery coming into Australia with lack of adequate safety equipment and proper training and information is extremely concerning to us.” Fibre laser cutting machines have revolutionised manufacturing with their precise cutting capabilities. However, the use of open Fibre laser cutting machines can pose significant risks that are often overlooked.

In this article, we will shed light on the specific dangers of 1070nm laser emissions on the retina and explore the reasons why people don't blink when exposed to this radiation. We will also discuss the importance of awareness among business owners in Australia, along with the personal and legal repercussions that may arise in case of injuries. Additionally, we will highlight the measures necessary to ensure machine safety, emphasizing the need to select a safe CNC Fibre laser cutting machine from a reputable manufacturer.

Unveiling the specific dangers

Open Fibre laser cutting machines are class 4 laser devices which emit laser radiation at around 1070nm, which can have fast and detrimental effects on the retina. The retina, a delicate tissue at the back of the eye, is particularly vulnerable to this specific wavelength. Prolonged or direct exposure to these laser emissions can cause severe damage, including thermal burns, retinal lesions, and even permanent vision loss.

The blink reflex conundrum

One of the reasons people do not blink when exposed to 1070nm laser radiation is due to the nature of the radiation itself. The radiation emitted by Fibre laser cutting machines is Near Infrared Light which is invisible to the human eye. Because the eye does not see or react to infrared light it fails to trigger the blink reflex, which is an automatic protective response to potential eye hazards. As a result, individuals may inadvertently remain exposed to the harmful laser radiation without blinking or seeking immediate protection. Safety guidelines emphasize the risks of reflected light and even diffused radiation, which can still pose considerable dangers to operators and bystanders if not properly controlled. By the time an individual realises that they have been exposed it will likely be too late and the damage can become permanent.

Awareness and legal repercussions

Business owners in Australia have a responsibility to prioritise workplace safety and protect their employees. Failure to address the risks associated with open Fibre laser cutting machines can lead to serious personal and legal repercussions. If an accident occurs and workers are injured due to laser radiation exposure, the business owner may face legal actions, financial penalties, and damage to their reputation. Additionally, injured workers may experience physical harm, psychological trauma, and potential long-term disabilities.

Ensuring safety measures

To mitigate the risks of open Fibre laser cutting machines and protect workers, business owners should take the following measures:

1. Select a Reputable Machinery Manufacturer: Choose a trusted manufacturer experienced in producing safe CNC Fibre laser cutting machines. Such manufacturers will assist in risk assessment and provide guidance on implementing proper safety protocols.

2. Implement Adequate Safety Measures: Install appropriate enclosures with interlocks to prevent access during operation.

Additionally, ensure the machine is equipped with safety features such as emergency stop buttons and protective barriers to minimize the risk of laser radiation exposure.

3. Provide Comprehensive Training: Ensure operators receive thorough training on the safe operation of the specific Fibre laser cutting machine they will be using. Emphasize the importance of wearing proper personal protective equipment (PPE), including laser safety glasses or goggles specifically designed to protect against 1070nm laser emissions.

4. Conduct Regular Inspections and Maintenance: Regularly inspect the machine for any faults, damage, or wear and tear. Adhere to a strict maintenance schedule to keep the machine in optimal working condition, reducing the likelihood of laser radiation leaks or other safety hazards.

Open Fibre laser cutting machines pose specific risks due to their emission of 1070nm laser radiation, which can cause severe damage to the retina. It is essential for business owners in Australia to be aware of these dangers and take proactive steps to ensure worker safety. By choosing a safe CNC Fibre laser cutting machine from a reputable manufacturer, conducting risk assessments, implementing safety protocols, and providing comprehensive training, businesses can create a safer work environment, protect workers from harm, and mitigate the personal and legal repercussions associated with accidents.

By addressing the specific dangers of 1070nm Fibre laser emissions on the retina, business owners can emphasise the importance of implementing appropriate safety measures. This includes providing laser safety glasses or goggles that offer adequate protection against the specific wavelength. These specialized eyewear options can significantly reduce the risk of retinal damage and vision loss, but are not a replacement for properly designed enclosures with safety interlocks. The safety zone around a class 4 fibre laser device without guarding extends more than 70 metres. Even reflected light from a wall or floor, or from under the cutting deck can permanently damage a person’s eyesight.

Conclusion

Protecting workers from the dangers of open Fibre laser cutting machines requires a multi-faceted approach. Business owners in Australia must prioritize safety by choosing a safe CNC Fibre laser cutting machine from a reputable manufacturer, implementing comprehensive risk assessments and safety protocols, providing proper training and protective equipment, and conducting regular inspections and maintenance. By taking these measures, businesses can create a safer work environment, reduce the risk of accidents, and protect both the well-being of their employees and their own legal standing in case of unfortunate incidents. artcnc.com
