Testing will determine if an ignition occurs during the drop of a Universal Sampler onto a push-mode bit in a flammable gas environment. Ten drops each of the sampler using both a push-mode and rotary mode insert onto a push-mode bit will be completed. If an ignition does not occur under the conditions set forth in this test, then a satisfactory level of confidence will be obtained which would allow field operations using these inserts and drill bit
