Which of the following are correct methods for reducing the exhaust volume designed for local exhaust hoods? B (A) Flanges added around the external suction hood; (B) In cold-process fume hoods, the suction opening is located at the top; (C) Slit-type edge shields that transform a low cross-section into a high one; (D) Slit-type edge shields that change equal-height slits into wedge-shaped slits
Which of the following are correct methods for reducing the exhaust volume designed for local exhaust hoods? USA: (A) Flanges added around the external suction hood; (B) In fume hoods for cold processes, the suction opening is located at the top; (C) Slit-type edge guards that transform a low cross-section into a high one; (D) Slit-type edge guards that change straight slits into wedge-shaped slits
A, C, D--------------------------------------（B---at the bottom）
Option ACD is correct; in option B, it should be placed at the bottom
