The machine produces hydrogen and oxygen gas and electrical charges are present on exposed conductors. Are there any operator health or safety hazards to be aware of?
Electrical Danger: the conductors are all exposed in ECD systems because the current carried is low voltage direct current. The National Electrical Code permits exposed conductors up to a threshold of 50 vdc. Most ECD/ECM systems operate well under this threshold. Gas Exposure: the volume of hydrogen and oxygen gas produced at the reaction is very small in most installations. Normal ventilation is sufficient to dissipate the gas and avoid danger. Machines in small confined rooms should be well ventilated and electrolyte tanks and vessels should provide for free exchange of fresh air. Salt Water Electrolyte: Typically we are using Sodium Chloride (table salt) or Sodium Nitrate (fertilizer) and water. These are no more hazardous to humans (skin contact) than bathing in the ocean. Some may have allergic reactions and therefore it is advised that operators wear gloves and minimize skin exposure as much as possible. Also, since the process releases metal by-products into the electrolyte tha
