Handling of Large Magnets
Please do not simply select a large magnet!
Handling large magnets is extremely dangerous due to their unimaginable adhesive power. Handling them carelessly without thorough precautions and knowledge can lead to irreparable accidents and tragedies. We are not responsible for any accidents or losses caused by handling magnets.
We may refuse to sell large magnets
Our company places the highest priority on the safety of our customers, and may refuse to sell magnets weighing more than 1.5 kg. If you are considering purchasing a large magnet, please ask us any questions before making your selection. If a finger, hand, or arm is pinched, it cannot be easily removed, and there is a risk of necrotic comminuted fractures and loss of the magnet. When handling large magnets, be sure to take all possible safety measures and have multiple people who are familiar with handling the magnet handle the magnet.
An example of an accident caused by handling a large magnet
While handling large neodymium magnets, round φ75mm x 70mm and square 100mm x 50mm x 50mm, the index finger of the right hand was accidentally pinched between the magnets, resulting in a comminuted fracture of the tip. The surgery took 90 minutes, and fortunately only the tip of the first joint needed to be amputated. The magnets used are shown below, and when the two magnets are attracted to each other, the adhesive force is approximately 362kgf (3,553 Newtons). In other words, a force of more than 362kg is required to pull the magnets apart.
When a finger, hand, or limb becomes trapped between large magnets and cannot be released
In the unlikely event of an accident, remain calm and take all possible action to avoid damage. If you determine that it is difficult to do it yourself, immediately contact emergency services and request rescue. If necessary, request that emergency services or a third party use non-magnetic tools that are not attracted to magnets when removing or separating magnets. If a crowbar, hydraulic jack, iron plate, or iron tools are used, these magnetic objects may be attracted to magnets and the damage may worsen, making rescue even more difficult.
Safety measures for handling large magnets
If skin gets caught between magnets, it may cause internal bleeding and the skin may peel off. If you are caught between magnets, wearing gloves may help you avoid injury. Please wear gloves or work gloves as necessary when handling magnets. Using non-magnetic tools or wood may help prevent disaster. When handling magnets, use tools made of stainless steel, which is non-magnetic and does not attract magnets. Besides stainless steel, the safest non-magnetic tools are classified as special tools and are sold as explosion-proof tools. Explosion-proof tools are made of copper and beryllium alloys (BeCu), such as beryllium copper and beryllium bronze, and are characterized by being non-magnetic and not generating sparks while being highly strong. The image shows a crowbar made of non-magnetic beryllium copper alloy, which does not attract magnets and has a high strength, so it can be used as a safety tool.
