Climate Screen Fire Safety Precautions
Greenhouse, garden center and nursery fires can be especially destructive, once a fire is underway it can spread very quickly.
The following steps should be reviewed and implemented to minimize fire risk associated with screens and shade cloths.
- Correct potential wiring problems that can result in fires
If wires are in contact with screens at any point in the coverage area, friction against the wiring is likely to result as the screen is opened and closed. Friction can wear away the insulation and expose a hot wire to greenhouse screens. One way to prevent this hazardous situation from occurring is to have all wiring in ceilings routed away from any moving systems and encased in metal conduit.
- Ensure that heating exhaust pipes are always at least 3 feet from screens that are not fire resistant
For other combustible materials, make sure a metal thimble is used where the vent passes through the material, such as a greenhouse end wall. For a new construction or replacement consider using a double-walled "Class B gas vent".
- Screen systems should be retracted (placed in a gathered position to form a natural fire break) if a fire should start
Vents should be manually closed and all air movement equipment should be shut down, if possible.
- Place proper firefighting equipment in each structure
ABC dry chemical fire extinguishers (5 to 10 pounds) should be used, with the number of extinguishers depending on the size of the building. Travel distance to a fire extinguisher should be no greater than 75 feet.
- Under no circumstances should garden hoses be considered adequate for fire extinguishing
A garden hose is 1/2 inch in diameter, as opposed to 2-1/2 inch for a fire hose. A garden hose is completely ineffective for addressing extremely fast-burning fires.
