Summary

TLDRIn this instructional video, a technician from PT Trihasco Utama demonstrates the detailed process of gas sampling in the field. They emphasize the importance of safety measures, including the use of gas detectors, protective masks, and gloves. The technician explains the equipment used, such as gas pumps and sampling cups, and outlines the steps involved in taking samples from the pipeline. After collecting the gas, the technician shows how the sample's color changes, indicating the type and concentration of gases like CO2 and H2S. This video offers a comprehensive guide to the gas sampling procedure and analysis.

Takeaways

😀 A person introduces themselves as a Horse Technician at PT Trihasco Utama.
😀 Their daily tasks involve taking gas and water samples for SLB (presumably related to safety or environmental monitoring).
😀 Before starting work, it's essential to ensure all necessary equipment is on hand, including a gas detector.
😀 Ensuring the safety of the work area is a priority before starting sampling activities.
😀 Personal protective equipment (PPE) such as a cartridge mask is required for gas sampling.
😀 The mask mentioned is a full-face type, suitable for protecting against various toxic gases.
😀 Gas sampling equipment includes a degpharm pump for extracting gas from pipelines and a sampling cup.
😀 Different types of sampling cups are used for various gases, such as one for H2SO.
😀 The proper preparation of the sampling equipment includes ensuring that the cups are sealed and intact before use.
😀 After breaking the seal of the sampling cup, it’s connected to a gas detection device (drager farm) to measure the gas content.
😀 A visual change in color indicates the presence and concentration of gases, such as CO2 and H2S, during the sampling process.

Q & A

What is the role of the person in the video?
-The person in the video works as a Horsen Technician at PT Trihasco Utama. Their job involves taking gas and water samples for analysis, particularly for SLB (Surface Leaking Bottles) at field locations.
What equipment is necessary before starting the sampling process?
-Before starting the sampling, it's essential to ensure that all necessary equipment is present. This includes a gas detector, PPSP (Personal Protective Safety Equipment) such as a mask with a cartridge, gloves, and other protective gear.
Why is it important to check the location before beginning the sampling work?
-It is important to check the location to ensure it is safe and free from toxic gases. Safety is a top priority before proceeding with any work in the field.
What type of mask is used, and why is it necessary?
-The mask used is a hole-type mask with a cartridge. It is designed to filter out nearly all types of toxic gases, ensuring the technician's safety during the sampling process.
What is the function of the gas pump (degepharm) mentioned in the video?
-The degepharm, or gas pump, is used to pump and collect the gas present in the pipeline. This is a critical tool for obtaining the required gas samples.
What is the purpose of the sampling cup?
-The sampling cup is used to collect specific gas samples, such as H2S (Hydrogen Sulfide) in the video. Different types of sampling cups are used depending on the gas being sampled.
How is the sampling cup prepared before use?
-Before using the sampling cup, it must be checked to ensure it is properly sealed at both ends. The technician then breaks the seal and inserts the cup into the house of the gas detector, ensuring everything is secure.
What happens after inserting the cup into the gas media?
-After the cup is inserted into the gas media, the technician presses the device, collects the gas sample, and then removes the cup. The gas sample collection is complete.
How is the gas sample analyzed?
-The gas sample is analyzed by observing the color change in the sample. For example, CO2 samples change from white to blue, and H2S samples change from white to brownish. The scale of the gas content is measured based on these color changes.
What does the color change in the gas samples indicate?
-The color change in the gas sample indicates the presence and concentration of the specific gas being sampled. For CO2, the color changes from white to blue, while for H2S, it changes from white to brownish, allowing technicians to gauge the gas content.
