Safety advice have been circulated for "what to do in case of imminent blast" including laying flat on your stomache with arms around back of neck, and keeping mouth open.

Yesterday, I was sympathetic to the volunteers preparing for funeral ..etc. It was very hot and humid. The sun was merciless. I approached them to ask if they needed anything. I was thinking of buying for them a few dozen snacks and a few cases of water and juice. But I was given immediate and serious sign of "turn around", which I followed.
