VirtLab «Life Safety and Labor Protection»

Software laboratory complex for the simulation of laboratory work on the main sections of the course of Life Safety and Labor Protection for technical specialties. The program complex includes simulation labs:

1. The Study of Microclimatic Conditions in the Working Area of Industrial Premises

OBJECTIVE: Familiarization with the theoretical foundations of rationing microclimatic factors, the study of instruments, measurement techniques and assessment of microclimatic conditions in the working area of the premises.

SUMMARY: Conducting laboratory work includes the sequential execution of a number of simulation experiments. The implementation of each simulation experience consists in performing a series of sequential actions in accordance with the standard experimental methodic. The experiment examines the main indicators of the microclimate of the industrial premises: humidity and air temperature, air velocity, atmospheric pressure and other indicators.

2. The Study of the Illumination of Workplaces in Artificial Light

OBJECTIVE: The study the principles of the regulation of illumination in the workplace, the study of illumination in the workplace using an analog luxmeter and an assessment of the level of illumination.

SUMMARY: A virtual lab simulates a specially equipped cabin, enclosed by a thick dark curtain. There are devices in the cab that allow you to turn on the general and combined lighting systems with fluorescent lamps and incandescent lamps, change the voltage in the electrical network using a laboratory autotransformer, and use multi-colored shields to simulate the color of the room walls.

3. The Study of the Effectiveness of the Ventilation System

OBJECTIVE: The study of a standardized method of aerodynamic testing of general exchange ventilation system and the determination of its effectiveness.

SUMMARY: In a virtual laboratory work, a specially equipped aerodynamic test bench of a general ventilation system is simulated. The simulation model of the laboratory bench includes a centrifugal fan with an electric drive, a duct of constant cross section, equipped with a special valve in the form of a lobe diaphragm, a measuring pneumometric tube (Pitot tube) and an analog micromanometer.

4. The Study of the Process of Static Electrification in Pneumatic Conveying of Granular Material

OBJECTIVE: The study the electrostatic spark hazard of the process of pneumatic transport of dielectric materials, the determination the sensitivity of the object under study to the igniting effect of a discharge of static electricity and assessing the effectiveness of the protective measures used.

SUMMARY: In virtual laboratory work, a specially equipped stand is simulated, including a solid-phase pneumatic transport system (there is transporting of a mixture of polymeric materials with a particle size of 3...5 mm in a closed circulation cycle), a device for recording electrical charges of static electricity, and a discharge chamber («bomb») with a capacity of 1 liter with two electrodes, one of which is attached to the aluminum lining of the bunker, and the second is grounded.

5. The Study of Electrical Safety of Electrical Installations with Voltage up to 1000 V

OBJECTIVE: Familiarization of the ability to properly assess and ensure the required electrical safety conditions for electrical installations with voltage up to 1000 V.

SUMMARY: The virtual laboratory work simulates the specially equipped stand with measuring devices (milliameter, ammeter and voltmeter), mnemonic panel, resistance shop and toggle switches of operating modes. The work also simulates additional measuring devices — an electronic megohmmeter (for measuring the insulation resistance of cable phases) and an electronic resistance meter for a grounding device. The laboratory work is divided into 3 educational and methodological parts: work with the stand; measurement of the insulation resistance of the cables; measurement of the resistance of the grounding device.

6. The Study of Flash and Ignition Temperatures of Flammable Liquids

OBJECTIVE: Familiarization of a standardized method for determining the flash point and ignition of flammable liquids in an open crucible.

SUMMARY: A virtual laboratory work simulates a special device for determining flash and ignition temperatures of flammable liquids in an open crucible. Laboratory equipment is placed in a fume hood that provides timely exhaust of the combustion products of the studied liquids. Are testing of 10 samples of flammable liquids: oil shale oil, oil varnish, diesel fuel, kerosene, white spirit, ethyl alcohol (ethanol), methyl alcohol (methanol), engine oil, aviation oil and acetone.
