Task 2.25. Act out the dialogue, employing interpreters from your group:


Students: Good morning! We are going to perform three lab exercises in your chemical lab on Friday. Will you tell us a few words about certain procedures to which we must conform while working there.

Lab assistant: With pleasure! As you see our chemical lab is modern and well-equipped. First of all, you should get acquainted with the safety regulations within the laboratory. You will know, for instance, that access to the lab is conditioned upon wearing safety glasses and a lab coat.

S: I’ve heard that lab coats should be cleaned and fastened, shouldn’t they?

LA: You are quite right, besides, they must be worn all the time in the lab. Now note the position of fire blankets and the fire extinguisher (вогнегасник) in the lab.

S: Will you show us the nearest escape route and assembly point in the event of evacuation?

LA: Certainly. It is this way, please. Now look at our apparatus. Take particular care handling delicate apparatus such as thermometers, glass electrodes etc. which are easily broken when their glass bulbs come into contact with other surfaces.

S: Wen, I know that many organic solvents are extremely flammable.

LA: Yes, it’s really so. That’s why you must be very careful while heating them. Besides, you should inform about any accidents or spillage either the technician or lab assistant (demonstrator) immediately.

S: At school our teacher of chemistry always asked us not to pipette solutions directly from reagent bottles. Was he right?

LA: Oh, for sure. You should always pour solutions into a beaker (мензурка) first, otherwise they can become contaminated. Besides, dispose of chemicals in the prescribed manner - Do not simply wash them down the sink!

S: It’s clear, and what are we required to do at the end of the experiment?

LA: First of all you must return all the mobile apparatus to the appropriate cupboard and solution reagent bottles to the shelf above the cupboard. Bear in mind that you must leave your bench clean and tidy. You should always remember that while working in our lab you are responsible for the health and safety of other students and staff.

S: Thank you very much for your instruction.

LA: You are welcome. Good bye.

The main equipment of the laboratory comprises electric resistance furnaces, thermoregulators and other facilities./ It serves as a central heating plant,/ It is a perfectly equipped laboratory.

B: Oh, there are students here. What assignment are they working on now?/ What are they investigating?

'A: They are dealing with heat treatment, such process as hardening. Here you can see instruments for determining hardness./ They learn to handle some new devices.

B: What device is it?/ Do they work without any assistance?

A: It is a radio-engineering device for measuring distances./ They usually work by themselves. But if a problem arises, they can ask the experienced laboratory assistant to help them.
