1- High Pressure Mud (HPM) is a drilling fluid used in oil and gas industry for the purpose of drilling, maintaining, and completing wells. It provides lubrication to the drill bit, cools it, carries away cuttings from the hole, supports the borehole walls, and acts as a seal against formation fluids.

2- Fire-water Sprinkler Control (FSC) is a system designed to automatically discharge water onto a fire when a predetermined temperature or heat release is detected. It consists of sprinklers, pipes, valves, and a control unit. The configuration of FSC can vary based on the building size, design, and fire hazard levels. A typical configuration includes a water supply source, pump, pressure tank, control valve, pipe network, and sprinkler heads.

3- The complete loop of vibration involves several steps: (1) A power source generates mechanical vibrations. (2) These vibrations are transmitted to the exciter which converts them into longitudinal or rotary motion. (3) This motion is then transferred to the shaker table through a transmission system like bearings, couplings, and mounts. (4) The shaker table vibrates in the desired frequency and amplitude, causing the payload on it to experience similar vibrations. (5) Sensors placed on the payload collect data about the vibration levels. (6) This data is then sent back to the control room where engineers analyze it and make necessary adjustments to the vibration settings.

4- A proxymitter is a device that uses light waves for communication between two points. It works by sending signals from one device called a transmitter, which converts electrical signals into light pulses, and receiving these signals on another device called a receiver. Proxymitter technology is used in various applications such as proximity sensors, automated guided vehicles (AGV), and wireless charging systems.

5- If your partner is exposed to H2S (hydrogen sulfide) during the job, immediately evacuate the area and provide fresh air. Monitor their condition closely for symptoms like headache, dizziness, nausea, and breathing difficulties. Seek medical attention if necessary.

6- In case of a leaking valve gland packing, graphite or PTFE (polytetrafluoroethylene) packing can be used due to their ability to handle high temperatures, pressure, and corrosive substances.
