Hazard Analysis: Soldering Stations

**Description of Work:** Assembly, testing and repair of electronic
circuits routinely involves the use of soldering stations. Soldering
stations generally consist of a soldering iron, soldering iron holder,
and a base unit. The soldering iron tip applies heat to liquefy raw
solder. Liquefied solder \"flows\" onto and between non-solder-masked
metallic areas of printed circuit boards and the metallic \"legs\" of
components. When the soldering iron tip heat source is removed, the
liquid solder solidifies and forms an electrically conductive bond
between the printed circuit board and the component[.]{.underline}

|              |            | a)  Use Touch-Sensitive Soldering        |
|              |            |     Stations such that the iron tip is   |
|              |            |     not heated unless the iron is        |

|              |            |     normally means the iron is in        |

|              |            |     off and unheated when the iron is at |
|              |            |     rest in its holder, there is no      |

|              |            | b)  Use Manually operated Timers on the  |
|              |            |     AC power lines sourcing the solder   |
|              |            |     stations, to shut the irons off      |
|              |            |     after a fixed period of time unless  |
|              |            |     the timer is manually reset.         |
