CSS3动画无效

我使用css3为SVG创建了一个动画,它在Chrome和Firefox中完美运行.它部分在Safari中工作但不能在Internet Explorer中工作(支持css动画的IE9 +)

见演示

CSS:

@-webkit-keyframes dash {
  70%,80% {
    stroke-dashoffset: 0;
    fill-opacity: 0;
  }

  85% {
    fill-opacity: 0;
    stroke-opacity: 1;
  }

  95% {
    stroke: #17739D;
    stroke-dashoffset: -301;
    stroke-opacity: 0;
  }

  100% {
    fill-opacity: 1;
    stroke-dashoffset: -301;
  }
}

@-ms-keyframes dash {
  70%,80% {
    stroke-dashoffset: 0;
    fill-opacity: 0;
  }

  85% {
    fill-opacity: 0;
    stroke-opacity: 1;
  }

  95% {
    stroke: #17739D;
    stroke-dashoffset: -301;
    stroke-opacity: 0;
  }

  100% {
    fill-opacity: 1;
    stroke-dashoffset: -301;
  }
}

@-moz-keyframes dash {
  70%,80% {
    stroke-dashoffset: 0;
    fill-opacity: 0;
  }

  85% {
    fill-opacity: 0;
    stroke-opacity: 1;
  }

  95% {
    stroke: #17739D;
    stroke-dashoffset: -301;
    stroke-opacity: 0;
  }

  100% {
    fill-opacity: 1;
    stroke-dashoffset: -301;
  }
}


@keyframes dash {
  70%,80% {
    stroke-dashoffset: 0;
    fill-opacity: 0;
  }

  85% {
    fill-opacity: 0;
    stroke-opacity: 1;
  }

  95% {
    stroke: #17739D;
    stroke-dashoffset: -301;
    stroke-opacity: 0;
  }

  100% {
    fill-opacity: 1;
    stroke-dashoffset: -301;
  }
}

#Layer_1 { 
    margin-left: auto; 
    margin-right : auto;  
    top: 50%; 
    position: absolute; 
    left: 50%; 
    margin-left: -65px; 
    margin-top: -35px;   
}

svg {
  background: #fff;
  display: block;
}

svg * {
  stroke: #666;
  #stroke: #17739D;
  stroke-width: 1;
  fill-opacity: 0;
  stroke-dasharray: 350;
  stroke-dashoffset: 440;
}

svg #bp_svg * {

  -webkit-animation-name : dash;
  -moz-animation-name : dash;
  -ms-animation-name : dash;
  animation-name : dash;

  -webkit-animation-duration: 4s;
  -moz-animation-duration: 4s;
  -ms-animation-duration: 4s;
  animation-duration: 4s;

  -webkit-animation-timing-function : linear;
  -moz-animation-timing-function : linear;
  -ms-animation-timing-function : linear;
  animation-timing-function : linear;

  -webkit-animation-fill-mode : forwards;
  -moz-animation-fill-mode : forwards;
  -ms-animation-fill-mode : forwards;
  animation-fill-mode : forwards;
}

任何人都可以帮我理清如何使其在Safari和IE中正常工作吗？
