Re: Gas leak. Remote terminals are vented to prevent that. There are fans constantly pulling air up and out of the cabinet. The only way that could happen is if the fans failed (which would trip an alarm) or someone physically blocked the air's pathway. |

Valencia, CA | In my neighborhood in Valencia, CA, Southern California Edison's 16 kV (buried) underground line went bad, and cooked AT&T's (SBC/PacBell) underground lines and burnt up a couple of blocks of underground wire. The wire was melted all the way to my ground block at the house. It took a couple of weeks to repair all the lines (new PVC, 22 AWG vs. 24 AWG) and my DSL works better  |

Unless those fans are explosion proof, which they are not, they are probably the ingition point of the explosion. |

| But if they're working the gas won't have time to buildup. |
|
| that would depend on how big the leak was. |
|
| But as I mentioned in another post. The generator is completely seperate from the actual DSLAM. For this reason. The only gas that could build up would be battery. And it ain't going to build that fast. |

said by bogey780:Remote terminals are vented to prevent that. There are fans constantly pulling air up and out of the cabinet. FWIW Most newer cabinets (MESA etc.) are sealed the inside air is recirculated and is not exchanged with the outside atmosphere. In order to keep the electroincs cooled they use heat exchangers not fans connected to the outdoors. This helps to keep the interior dry and nice and clean.
Last year I heard of a MESA 4 that exploded when a tech opened the door. Investigation revealed the charger/alarm failed and battery string had gone into thermal runaway filling the interior of the cabinet with hydrogen gas when the tech opened the door something sparked and the rest was history.
As for gas that can also be a problem most cabinets have conduit running from them and if not properly sealed sewer (methane) gas can migrate up the pipe from the manhole and into the cabinet add one spark from a relay contact and boom it’s all over for that RT.
