Abstract
Effluent containment devices are made of flame-resistant material having a Flame Spread Index of greater than zero and less than 30. The material may also have anti-static properties, such as being formed of a dissipative material or one that resists flow electrification.
Claims19
An effluent containment device for handling effluent from a hydroblasting operation, comprising:
- an interface portion adapted for coupling with an end of an effluent source;
- an enclosure adapted for containing effluent from a hydroblasting operation, the enclosure having a sidewall that is flexible and formed of material comprising a flame-resistant material having Flame Spread Index (FSI) greater than zero and no more than 70;
- whereby the sidewall will not support self-sustaining combustion upon encountering a combustion initiation source.
The effluent containment device of paragraph 5 wherein the effluent containment device is adapted to generate no more than 400 volts upon flow electrification during hydroblasting.
The effluent containment device of paragraph 5 wherein the effluent containment device is adapted to generate no more than 200 volts upon flow electrification during hydroblasting.
The effluent containment device of paragraph 5 wherein at least a portion of the sidewall has an electrical surface resistance between 1×10{circumflex over ( )}6 ohms/square and 1×10{circumflex over ( )}11 ohms/square, such that the sidewall is classified as dissipative.
A vessel and effluent containment device combination comprising:
- a vessel that is a source of effluent;
- and
- an effluent containment device mounted on the vessel and adapted for containing the effluent, the effluent containment device comprising:
- an interface portion adapted for coupling with an end of an effluent source;
- an enclosure adapted for containing effluent from a hydroblasting operation, the enclosure having a sidewall that is flexible and formed of material comprising a flame-resistant material having Flame Spread Index (FSI) greater than zero and no more than 70;
- whereby the sidewall will not support self-sustaining combustion upon encountering a combustion initiation source.
