We use can use a warning line system for fall prevention if the roof has a slope of 4/12 or less, is wider than fifty feet and has parapet walls less than 39" high. The warning lines can be made of wire, rope, or chain and flagged every six feet.  The warning lines must be supported by stanchion posts that can withstand a tipping force of at least 16 pounds.  The height of the warning line from the roof surface must be between 34 and 39 inches.  And the tensile breaking strength of the warning line should be at least 500 lbs. The open edges around the roof work site should be guarded by warning lines.  These have to be set six feet from all edges when no mechanical equipment is being used.  When mechanical equipment is being operated, the warnin... » Read more

We can't discuss torch applied systems without first talking about propane safety.  Propane or LPG (liquefied Petroleum Gas) is a fuel gas that is compressed and stored in pressurized tanks.  The tanks or cylinders come in different sizes with the most common for our industry ranging  between 20 and 100 pound cylinders.  A small tank being used in cooler weather may frost.  Let it thaw naturally and never torch the cylinder to defrost it.  Propane cylinders should be kept upright and chained/secured in that position .  They should be positioned in areas away from equipment or vehicle traffic.  They should be located away from any heat activity so they don't over heat. Use care when lighting a torch and when handling a lit torch.  Check all connections and hoses for leaks before you start.  Never use a... » Read more

Let's talk about what makes a fire and what we can do to prevent one. Fire can be compared to a triangle. Three sides are necessary to make a triangle and three ingredients are necessary to cause a fire. These are heat, air, and fuel. If any one of these three sides is missing, there can be no fire.   HEAT Heat, the first side of the fire triangle, can come from many sources. It can be generated by sparks from welding operations, discarded cigarette butts, electrical shorts, frayed wiring, friction from power tools, and hot exhaust pipes.  FUEL Fuel, the second side of the fire tr... » Read more
