livestock or unauthorized persons and guarding, blocking, or barricading roads leading into the <br />blasting area. The vicinity of charged holes will be barricaded, posted, or flagged against <br />unauthorized entry. The all clear signal shall be given only after the area has been checked to <br />insure that no unusual hazards such as slides or undetonated charges exist and access to <br />or travel through the area can safely resume. <br />Unavoidable Hazards <br />This is a list of some unavoidable hazardous conditions that may dictate blasting at times other <br />than the posted time period. The following conditions shall be cause for detonation under <br />emergency conditions: <br />Records <br />a. Destruction of damaged or deteriorated explosives or detonators in a safe manner. <br />b. Disposal of misfires and /or undetonated explosives. <br />c. Firing of charged holes as soon as practical after cessation of static electricity or stray <br />current conditions when electric detonators are used. <br />d. Firing of charged holes when weather conditions indicate the existence of an eminent <br />safety hazard. <br />e. Operator safety or safety considerations for the general public. <br />WFC will maintain blast records according to Rule 4.08.5. Each blasting and seismograph <br />record shall be retained for a period of three years following the date of the blast. Copies of <br />these records will be maintained at the mine and made available for inspection. WFC has five <br />(5) blast monitoring devices at present time. See Attachment 2.05.3(6)(a) -3 for detailed <br />specifications of these machines. These machines will usually be placed at the nearest <br />inhabited dwelling(s) along with other none inhabited structures such as sewer pipelines, <br />irrigation ditches and other structures. The closest structures will take monitoring precedence <br />over further structures due to the limited number of monitoring machines. <br />Section 2.05.3(6)(a) <br />Page 10 February 12 <br />
