H&S Instructions for Magnets
Massive force needs responsibility.
Safety first. Strong magnets, although small, contain enormous energy. Read the rules below to prevent injuries damage to body and equipment.
Safety checklist!
Handling guide
Before starting, read the rules. Sudden snapping can destroy the magnet or injure your hand. Be predictive.
Finger safety
Big blocks can smash fingers in a fraction of a second. Never place your hand between two strong magnets.
Risk of cracking
Neodymium magnets are sintered ceramics, meaning they are very brittle. Clashing of two magnets will cause them cracking into small pieces.
Adults only
Neodymium magnets are not suitable for play. Swallowing a few magnets can lead to them pinching intestinal walls, which constitutes a direct threat to life and requires immediate surgery.
Warning for heart patients
Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.
Cards and drives
Do not bring magnets near a wallet, computer, or TV. The magnetic field can destroy these devices and erase data from cards.
GPS Danger
GPS units and smartphones are extremely susceptible to magnetism. Close proximity with a powerful NdFeB magnet can decalibrate the sensors in your phone.
Skin irritation risks
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction appears, cease working with magnets and wear gloves.
Operating temperature
Standard neodymium magnets (grade N) lose power when the temperature surpasses 80°C. This process is irreversible.
Fire risk
Powder generated during machining of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
