    Most folks think that chemical hazards are strictly limited to manufacturing or other industrial sites.  The fact that there are potential chemical hazards in the safe confines of their homes often comes as a surprise.

    A surprising number of residential fires are caused by the spontaneous combustion of stain application materials.  When an oil-based stain is applied to furniture or flooring, the oils react with the oxygen in the air to form very large polymer chains.  The process of the liquid stain turning to solid barrier is called curing (it is not drying via evaporation) and the reaction is oxidation.  This reaction generates heat.  On the floor or chair, the heat dissipates into the room without an issue.  That same oxidation reaction is occurring on the brush, towel, sponge, or rag that was used to apply the stain.  If those materials are piled in a corner or in a trash can, the heat cannot dissipate.  If there is enough product present, enough heat can be generated to (more…)

    Fire protection is an expanse that I am both fascinated by and passionate about. To prove it, I could show you my sprinkler collection… the old ones, the new ones, the sizes, the features!  But instead, I will share some information to show you the relationship between fire protection systems and other systems that you may have never thought about!

    Fire protection, suppression, and alarm systems often do not act alone. They can be in cahoots with life safety systems or other equipment or building systems to mitigate fires and help firefighters. Many, but not all, of these functions are associated with fire alarm systems. Many, but not all, of these functions are customary and expected. Some of these functions will automatically reset when the alarm or system is reset, but not all! (more…)
