  • 6 Mine Safety Tips To Keep You Accident-Free

    Take Care of Your Physical and Mental Health. Working in mining can be both physical and mentally strenuous. Staying well nourished and rested will go a long way to preventing accidents. Identify and Communicate Hazards. When you spot a hazard, be sure to communicate this to your supervisor and ensure it’s clearly labeled. Even if the current situation isn’t hazardous but there’s potential for it to become one, proactively addressing it will ensure your safety and your entire team’s safety. Protect Your Lungs. To keep your lungs protected, always make sure you’re using the right respiratory protection, whether it’s just a facemask or more complex protection. Fall Protection. Fall hazards at mines range from shafts, slipping on the side of a steep hill, or even tripping over equipment, and more. Falls from a height, such as down shafts, are especially challenging because specialized equipment and rescue training may be required to retrieve the injured worker.

    Prioritize Planning. Whether in surface or underground projects, itcritical for miners to develop thorough plans before beginning work. Taking time to calculate the best approach can help the process to go more smoothly and protect the well being of the whole crew. Maintain Rigorous Standards. Exercising regular inspection and adherence to mining regulations can set high expectations for workers. You can instill a sense of responsibility and attentiveness on your job site by meticulously enforcing safety rules. Wear Personal Protective Gear. Labor intensive jobs all have specific personal protective gear needs, and mining is no different. Head-to-toe protection can shield miners from impacts, chemicals and extreme temperatures. Pay Attention to Equipment Upkeep. Unchecked, aging parts can go unnoticed, and worn-out valves or brakes can lead to loss of control. Old or defective equipment can open up dangers to a site, but regular cleaning and repair can keep machinery in optimal shape.
