ElectroStrip(TM) Technology

A Primary Mission of the Council is to promote effective means of surface preparation in the maintenance industry using water and water/abrasive blasting techniques.

An electrolyte is contained in a liquid-absorbent material to which a counter electrode is attached.

This apparatus, often combined with a liner, is attached to the painted metal surface (typically steel) with magnets.

A DC voltage of 8 to 10 volts is applied for ½ to 2 hours.

ElectroStrip(TM) Corporation (Export, PA) was contracted to remove the existing coating system from one interior beam on the west abutment span of structure 2067 utilizing their ElectroStrip(TM) technology.

Connections made while under electrical load will arc with high-intensity light flash and high temperature, capable of causing injury.

Faulty ground may also result in personal injury if a worker provides an alternate path to ground.

A maximum productivity rate of 10 ft2/man-hr was observed during the demonstration.

The last two days showed a drop in productivity because the contractor did not assist with the process.

Air monitoring during the Hand/Power tool cleaning of the remainder of the structure showed the air borne Lead dust levels were well over the OSHA PEL for Lead.

‘Once-through’ abrasive blasting will typically have two blasters, one helper, and one foreman having an equivalent productivity rate of 50 ft2/man-hr.

‘While structure was grounded to complete the circuit’ perhaps the following would be clearer: ‘While the connection to the inherently grounded structure completed the circuit’ Faulty ground as occupational hazard: voltages not exceeding 18 V (max. voltage of our rectifier) are generally considered to present no shock hazard.
