The purpose of this alert is to remind everyone of a frequently overlooked hazard involving Synthetic Based Mud (SBM) additives. SBM is typically shipped to rig locations in tote tanks. Once on location, it is usually gravity fed to mud pits through flexible hoses. Synthetic Based Mud additives with a flash point of 73F (23C) meets the standard of a Class 1C flammable liquid. (Check the SBM additive MSDS sheet for flammability.) Decanting SBM additives with a low flash point without bonding and or grounding can result in an explosion.
