Fire extinguishers will be:  Conspicuously located  Inspected monthly  Protected from freezing  Placed within the immediate area of sufficient strength any welding/cutting operation or flammable liquid storage area  Placed within five feet whenever gasoline-operated equipment is used If a fire extinguisher is discharged for any purpose, it should be reported to AHB, Inc. All temporary buildings and trailer complexes (shops, field offices, conex’s, etc.) will have a class ABC fire extinguisher located within the building. Access to fire hydrants, buildings and other structures will be maintained at all times. Fire Prevention: Temporary buildings located within another building or structure shall be laid tight constructed of non-combustible material or have a fire-resistance rating of at least one (1) hour. Plastic tarps or covers (visqueen) used for any purpose inside a building where welding, cutting, or open flame is present will be made of fire-retardant material. Combustible refuse from construction operations will not be burned or dumped anywhere on the construction site. Such refuse will be removed at frequent intervals, as needed. Storage of large quantities of construction debris will be placed in metal dumpsters. Storage of compressed gases will be:  Stored with valve caps securely on when not attached to a regulator  Secured upright at all times, including when transported in vehicles  Separated in accordance with OSHA requirements  Empty cylinders stored separately from full cylinders Only approved high flash point solvents are to be used for cleaning purposes. Oily rags and secured waste are to be stored separately in metal containers fitted with self- closing lids and must be removed from the building and disposed of properly at the end of each shift. Trash and refuse must be placed in trash containers provided for that purpose. A minimum clearance of 15 feet from fire hydrants must be maintained at all times. All fire safety rules and signs on this project will be observed and obeyed. Fire and Flammable Liquid Storage and Dispensing: High flash and methylene chloride solvents are prohibited. Flammable Liquids will be:  Stored outside, not within 20 feet of any structure or in a properly constructed storage locker, whenever possible  Stored in approved portable containers that are marked as to its contents  No more than 25 gallons stored inside any trailer or room  Posted with “NO SMOKING” signs. When a large number of workers speak a foreign language, the warning signs will be posted in that language, as well  Outside storage areas kept free of weeds and other combustible material All flammables will be stored in approved containers and marked as to the contents. if storing flammables for more than one day, contact AHB, Inc. for approval. Storage of flammables will be in an enclosure away from open flame, heat, direct sun or other sources of ignition. Transportation and transferring of volatile liquids will be made in Underwriter Laboratory or Department of Transportation approved containers. All gasoline or diesel storage tanks/drums will be placed in a berm or other secondary containment. Berms will be lined with minimum 6-mil plastic sheeting that is fuel- resistant. PVC linings are not allowed. Fuel and flammable liquid tanks, drums, or barrels will have the proper DOT placard and be labeled as to content. If workers speak a foreign language, the labels will also be in that language. LP gas storage tanks will be protected from vehicle traffic. At fuel dispensing points, the following is required:  Portable 20 B-C fire extinguisher within 25 to 75 feet from the fueling point  No smoking signs posted. Additional signs in a second language, if required  Self-locking fuel nozzle prohibited  Spill kit stored nearby  Tanks will be grounded and when dispensing flammable liquids, the containers will be bonded HOT WORK Hot work is defined as the use of open flames, other heat sources and/or spark- producing devices in areas where combustible materials may be or do exist or where there is potential for explosion or fire. Hot work activities include burning, welding, cutting, grinding or other operations that produce a flame or sparks that could cause catastrophic results if not controlled. Therefore, prior to performing “Hot Work” operations, workers will obtain a Hot Work Permit from the AHB, Inc. superintendent. A Hot Work Permit must be obtained daily. See Appendix F for the Hot Work Permit form. The following precautionary measures will be taken when a Hot Work Permit is required:  Grating, openings, etc., will be completely covered in such a way to prevent movement • Provisions sparks and slag from falling to a level below  Fire extinguisher in the immediate area or work  No flammable or combustible material stored within 35 feet in any direction  Combustible/flammable materials that cannot be moved must be covered with fire blankets or other suitable material  Worker(s) designated as fire watch will be trained and remain for one-half hour after work has ended  Follow confined space entry procedures, if required When burning or welding using compressed gases, back-flame arrestors will be installed on the regulator side of the oxygen and gas hoses or in accordance with the torch manufacturer’s recommendations. Welding screens will be used whenever possible to protect workers from welding flash. Each subcontractor is responsible for training workers prior to performing any hot work. The training will consist of:  A review of the work to be performed  Emergency procedure in case of fire  Precautions to be taken  How to use the fire extinguisher correctly  Duties of fire watch SCAFFOLDING All scaffolding used on this project will meet the requirements established in OSHA 29 CFR 1926 Subpart L. Each contractor using scaffolds must designate a scaffolding competent person to direct and supervise the erection and dismantling of all scaffolding on this project. The competent person will sign and attach one of the following color-coded scaffold tags to each scaffold:  Green tag: Scaffolding complete and ready for use  Red Tag: Scaffolding incomplete and not for use  Yellow Tag: Scaffolding usable but personal fall protection required Scaffolding will be inspected daily by the competent person prior to use. Workers required to work from scaffolding will receive training from their employer on the following:  Nature of any known hazards, such as electrical, fall or falling objects  Correct method of erecting, maintaining, and disassembling fall protection systems  Falling object protection  Proper handling of equipment or material on the scaffold  Maximum load-carrying capacity of the scaffold  Any other pertinent requirements about the scaffold During erection and dismantling of scaffolding, if deviation of the fall protection procedure is required, approval will be required by the AHB, Inc. Project Safety Manager. Records of scaffolding training will be maintained and will be available for review by AHB, Inc. Prior to erection, all scaffolding components will be inspected for defects and any damaged components will not be used. Scaffolding will be erected on a firm foundation/footing. Scaffold poles, legs, posts, frames and uprights will bear on metal base plates and mud xxxxx, where required. Scaffold legs, poles, posts, frames and uprights will be pinned or locked to prevent uplift. No scaffold will be enclosed unless a qualified engineer designed the enclosure. Scaffold platforms will be constructed with no space between the platform components. The space between the platform components and the scaffold uprights will not exceed one inch. Because of special circumstances such as building a scaffold around a pipe, the space opening between the scaffold and the object/structure cannot exceed 9-1/2 inches.
