3. JOB HAZARD ANALYSIS Potential hazards fall into the following groupings: Hazards common to all heavy construction sites;Hazards related to the explosive nature of fuel tanks; Hazards due to chemicals and pollutants. Construction heavy equipment hazards will be minimized due to very few personnel being on the site, thereby minimizing the risk of unplanned equipment/human contact. Equipment stability(roll over)is not an issue since the backhoe will be operating on level terrain. Underground Service Alert(USA)need not be notified since no excavation is to take place. There are no overhead lines near the work area. Mr. Willis will not dig close to any live electrical or fuel lines. Proper clothing,including a hard hat,will be wore at all appropriate times. Empty fuel tanks can pose a fire or explosive hazard. To mitigate such hazard, the tank has been rendered inert through the displacement of combustibles with steam and water during the rinsing and cleaning that took place on February 3, 1998. A gas meter will be used to monitor the L.E.L.before dropping the concrete into the tank. Work near the tank shall not proceed until the combustibles have been reduced to a safe level. Chemical and pollutant hazards are not anticipated. All diesel product has been removed as noted above. While contact is not probable,should it occur,thorough washing of the skin should mitigate any negative effects. There is a probability that contact will be made with the outside asphalt coating of the tank, if it exists. Said contact should be benign and can be mitigated by washing of the skin. If any unforeseen chemicals are discovered,the job will be stopped until said chemicals are dealt with and a plan developed for its avoidance or removal. 4. JOB HAZARD SUMMARY Avoid construction hazards by limiting unauthorized/untrained people on the job site. Use conservative techniques during the filling of the tank with concrete..Personnel are to wear proper clothing for the task. Monitor the levels of hydrocarbons throughout the operation. If the L.E.L. level is unacceptable,the vapors shall be displaced by inserting dry ice through the two holes that have been cut in the top of the tank.. No work shall be done until safety has been established as shown by a gas meter. Expected chemical exposure(asphalt&diesel)contact is to be avoided. If skin contact is established proper washing with soap and water should ensue. If unexpected chemicals are discovered,they are to be avoided. If unavoidable,all work should stop and the job site should be secured until a contingency plan is developed.
