Question: How to sample toxic gases? Answer: ① Stand upwind or in a direction perpendicular to the wind direction. ② Do not block the airflow coming from upstream with your body. ③ Be sure to wear a gas mask and other protective equipment. ④ Open the valve slowly to replace the air in the container. ⑤ Have someone supervise the sampling process to prevent any accidents. ⑥ Close the sampling valve after sampling is complete.

1. Ensure proper personal protection by wearing appropriate protective equipment; select the right gas mask or respirator based on the toxicity of the substances. 2. Carry a combustible and toxic gas detector. 3. Take samples strictly in accordance with the sampling methods specified in the operating procedures.
1. Stand upwind or in a direction perpendicular to the wind direction； 2. One’s own body cannot block the wind flow from upstream ； 3. Wear a gas mask and protective gear properly ； 4. Slowly open the valve to replace the bladder ； 5. Someone should be present to supervise the sampling in case of any issues.
Answer: ① Stand upwind or in a direction perpendicular to the wind direction. ② Do not block the airflow coming from upstream with your body. ③ Be sure to wear a gas mask and protective gear. ④ Open the valve slowly to replace the air inside the bag. ⑤ Have someone supervise during sampling to prevent any accidents. ⑥ Close the sampling valve after sampling is complete

Close the sampling valve after sampling is complete.
Common collectors include absorbent liquids and absorption tubes (large bubble absorption tubes, small bubble absorption tubes, porous glass plate absorption tubes, impact absorption tubes, etc.), wave materials and sampling clamps, solid adsorbent tubes, syringes, plastic bags, etc. The collectors used should meet the corresponding specifications required by the instruments； Inspections and verifications must be carried out before sampling.
