It also provides protection against fires, overheating, and <br />destruction of insulation on wiring. <br />GFCis can be used successfully to reduce electrical hazards on construction sites. <br />Tripping of GFCIs - interruption of current flow - can be caused by wet connectors and <br />tools. It is good practice to limit exposure of connector and tools to excessive moisture <br />by using watertight or scalable connectors. Providing more GFCls or shorter circuits <br />can prevent tripping caused by the cumulative leakage from several tools or by leakage <br />from extremely long circuits. <br />(Adapted from OSHA 3007; Ground Fault Protection on Construction Sites, 1987). <br />7.6 Fire Prevention <br />Only Factory Mutual (FM) approved fire safety cans will be used to transport and store <br />flammable liquids. <br />All gasoline and diesel -driven engines requiring refueling must be shut down and <br />allowed to cool before filling. <br />Smoking is not allowed during any operations within the work arca. <br />No open flame or spark is allowed in any arca containing petroleum products or other <br />flammable liquids. <br />7.7 General Health <br />Medicine and alcohol can increase the effects of exposure to toxic chemicals. Unless <br />specifically approved by a qualified physician, prescription drugs should not be taken <br />by personnel assigned to operations where the potential for absorption, inhalation, or <br />ingestion of toxic substances exists. No persons are allowed on-site while under the <br />influence of drugs or alcohol or under any diminished capacity, whatsoever. <br />Drinking alcoholic beverages is prohibited. Drinking alcoholic beverages and driving is <br />prohibited at any time. Driving at excessive speeds is always prohibited. <br />Skin abrasions must be thoroughly protected to prevent chemicals from penetrating the <br />abrasion. <br />It is recommended that contact lenses not be worn by persons working on the site. <br />7.8 On -Going Training <br />The health hazards posed by the primary contaminants on this project will be discussed <br />over the course of the project at weekly "tool box safety meetings" to serve as a <br />refresher to this instruction. <br />The health hazards posed by the primary contaminants on this project will be discussed <br />over the course of the project at weekly "tool box safety meetings" to serve as a <br />refresher to this instruction. <br />Page 12 of 25 <br />P.14 <br />
