The invention provides an operation cabinet for a laboratory. The operation cabinet comprises a working cabinet, a supporting frame group, a top cabinet and a control mechanism, wherein the top cabinet is mounted above the working cabinet through the supporting frame group; a first observation window and a second observation window are movably mounted on the supporting frame group; a first driving device, a second driving device, a third driving device and a fan are mounted in the top cabinet; the first driving device is in drive connection with the first observation window; the second driving device is in drive connection with the second observation window; the third driving device is in drive connection with a commodity shelf; a plurality of air guide holes are formed in the bottom of the commodity shelf; each air guide hole is communicated with a fan air inlet through a pipeline; a fan air outlet is connected with an air outlet pipe; a filter screen is mounted in the air outlet pipe; the control mechanism comprises a control device, a gravity sensing device, a light ray emitter, a light ray receiver and a control switch. According to the operation cabinet for the laboratory, the internal environment of the laboratory and the health of a human body can be effectively protected.

The invention discloses a mounting method of a fire emergency marker lamp. The mounting method comprises the steps of step I, fixing a lamp shell of the fire emergency marker lamp to the wall surface; step II, laying a gravity sensing ground mat of the fire emergency marker lamp on the ground, with the bottom layer of the gravity sensing ground mat fitting the ground and the gravity sensing ground mat positioned behind the lamp shell of the fire emergency marker lamp; and step III, repeating the step I and the step II to lay a plurality of fire emergency marker lamps along an escape route, with the lamp shells and the gravity sensing ground mats of the adjacent fire emergency marker lamps being flush. The mounting method of the fire emergency marker lamp is matched with a fire emergency marker lamp applied by the inventor on the same day. The fire emergency marker lamp can be utilized for guiding the blind to acquire the escape route, so that the blind can conveniently escape from the fire scene, the personal safety of the blind is guaranteed, and the casualties are reduced.
