The ruling states that 1 If the substance produced is highly toxic, the labeling must contain the word "Danger" and the statement "Poisonous gas formed when used to extinguish flame or on contact with heat " 2 If the substance produced is toxic, label ing must contain the word "Warning" or "Caution" and the statement "Dangerous gas formed when used to extinguish flame or on contact with heat " 3 Whether or not the substance produced is toxic or highly toxic, any fire extin guisher that, if used on an electrical fire, would be likely to cause electric shock must be labeled "Caution Do not use on electrical fires " All fire extinguishers producing toxic or highly toxic sub stances must also be labeled "Use in an enclosed place may be fatal" and "Do not enter area until well ventilated and all odor of chemical has disappeared " A product is "toxic" under the law if it has the capacity to cause personal injury to man through ingestion, inhalation, or absorption through the body surface A product is "highly toxic" if tests have shown that it produces death in test animals under con trolled conditions The above information is an amendment to the Federal Hazardous Substances Labeling Act published m the Federal Register, Vol 27, Apnl 5, 1962, p 3255 Miscellaneous equipment Wheeled equipment. Large portable units on wheels are commercially available and include 17-gal and 30-gaJ soda-acid, loaded stream, calcium chloride, and foam types, 50-lb, 75-lb, and 100-lb carbon dioxide types, and 150-lb and 350-lb dry-chemical types (See Fig 36-23) Wheeled "twinned" extinguishers With the development of fluorocarbon surfactants that are water soluble, foam agents are avail able that give water the property of floating m thin layers on liquid fuel surfaces ("light water") This charactenstic provides ex cellent protection against reflash on liquid hydrocarbon fires with only one-fourth the volume as compared to protein/air foam A combination wheeled extinguisher with "purple K" dry chemical and "light water" fluorocarbon foam provides a synergistic ex tinguishing system with both rapid knock down of flames and complete protection against reflash The two agents are simul taneously applied through dual pistol-gnp nozzles Vehicle-mounted equipment Water, foam, carbon dioxide, and dry chemical ex tinguishing agents are available m units that are mounted on vehicles They range in size from m-plant fire vehicles capable of turning in warehouse aisles, to large trucks suitable for refinery or airport protection Fire blankets. In some cases, fire blankets can be used to smother a small fire Their major purpose is to extinguish burning cloth ing, but they are useful, too, for smothering flammable liquid fires m small open con tainers Asbestos and flameproofed woolen blankets are available, the most common size is 66 by 80 m Blankets are usually stored m con tainers mounted on a wall or column, so arranged that they can be readily pulled out Miscellaneous hand equipment Five-gal or 2'/2-gal water or antifreeze back-pack tanks are available with hand pumps built into the hose nozzle handles This type of unit is earned on the back, and the slide action pump is operated with both hands The back-pack unit is frequently used for combating brush fires Training ot employees When a fire breaks out, the first steps are to evacuate the building occupants safely, and to call the fire department, but it is also important to apply prompt control measures when the fire is small Regardless of the size or the hazard involved, plans should be made for a well maintained, efficient fire alarm system, and effective fire fighting Extinguishers are effective only when fires are in the first stages, and it is essential that they be immediately accessible and promptly used Extinguishers are only as good as the operators using them It pays to train key workers on each shift frequently and 1107
