Long runs of unprotected, PVC or plastic rubber sheathed combustible cables, usually supported by cable trays, are prone to rapid fire spread /generation of toxic smoke /acid gases and can thus cause excessive damage to men & materials. Unprotected cables burn & propagate fire after only a few minutes of exposure to fire/ flames. Power required for vital control functions, supplies and services fail very quickly. Burning cable sheaths carry the fire rapidly forwards and the burning PVC gives off aggressive toxic vapors. Indirect damage from cable fires (fire travel, breakdowns, corrosion resulting from harmful gases affecting sensitive instruments), is generally greater than the fire damage, initially visible.
Cable Fire Suppression Coatings are thus a critical step in achieving fire safety and ideally, they should provide the following three key protections:
- Fire Resistance
- Flame Retardance
- Smoke Prevention
- Good adhesion of the coating facilitates vertical and overhead application, minimizes cleanup.
- Does not affect the capacity of the cables to carry current, therefore, it does not require that the cables be de-rated does not attack or harm standard cable jacketing.
- Conforms readily to cable shape and maintains flexibility indefinitely, allowing for cable movement or removal.
- Virtually maintenance free; does not crack or deteriorate significantly with age, resists attack from harsh environments.
- Dries to the touch approximately 2 to 4 hours after application and cures thoroughly in 24 to 48 hours, depending on temperature and humidity.
- The product can be applied easily by brush or spray by a contractor or in-house maintenance crew with no extensive training.
- A safe, non-flammable, latex emulsion, it involves no job-site hazards, mixing, or thinning; cleanup is accomplished with soap and water.
- Suitable for both indoor & outdoor use. Weathering resistant. Post curing will not wash off with rainwater.
- The release of hydrochloric acids vapors is slowed down considerably by using Firex EC 43. Acid vapors that are released are neutralized. There is no subsequent burning of protected cables after the direct effect of a fire has been halted.
A thorough cleaning of cables is not required. However, oil or grease should be removed with dry rags (no solvent). Using a broom or vacuum cleaner to remove heavy layers of dust is sufficient.
Application by spray is done in a conventional way by spraying crosswise. The Light Grey color of the coating should well cover the color of the cable jacket. Generally, the required thickness may be applied in one coat. However, where new vertical cables are to be coated, it is recommended to first apply a thin “fog coat” and let it dry, then apply the final coat.Desired thickness can be achieved in two-three coats.
Brushing Firex EC 43 Coating on all cables requires 2-3 coats to build up the required thickness. Again, a thin coat applied first and allowed to dry will aid in building up the required thickness.
