The Vapors

'Tis the season for working inside the boat. In most cases, the boat is a tightly sealed boat with minimum ventilation and that can create conditions that might not be a problem in the summer but this time of the year can be hazardous.

Fumes from painting or cleaning solvents may collect in concentrations high enough to create the risk of a fire or even explosion if an ignition source is present. Simply pulling the trigger on an electric drill or flipping a light switch might lead to more than a bad memory.

If you are thinking about using any solvent or fuel fired heating device, take a look at the table linked below to find a clue as to the best type of ventilation to provide, i.e. a high level vent for lighter than air fumes such as natural gas, or vent ducts in the bilge for heavier fumes such as propane or most hydrocarbon solvents.
