Ventilation of chemical laboratories

Order design and installation of ventilation for chemical laboratories

ABL Engineering Group carries out a full cycle of work – from technical calculation of parameters and design of the ventilation system to the supply of equipment, installation of air ducts and commissioning of automation. Over the years, the company has completed 40+ industrial and laboratory facilities, gaining expertise in projects with increased requirements for air safety.

Chemical laboratories are facilities with a high concentration of harmful substances in the work area. Supply and exhaust systems here are required not only to provide air exchange, but also to control the air supply speed in each zone, maintain a vacuum in fume hoods, ensure purification of the exhaust flow through specialized filters and exclude the recirculation of contaminated air into work areas. Our engineers calculate the air exchange rate, select fans with the required pressure and performance characteristics, and design air duct routes taking into account the laboratory layout and the location of fume hoods.

Our own production in Temirtau – two workshops with a total area of more than 1,000 m² and a CNC machine park – allows us to produce non-standard elements of the ventilation system in strict accordance with the design documentation. This eliminates dependence on third-party suppliers and reduces installation time.

What is included in the comprehensive service:

• Technical calculation and design of the ventilation system taking into account SNiP and SanPiN standards for chemical laboratories
• Selection and supply of fans, air ducts, air purification filters and fume hoods
• Installation of supply and exhaust units and air duct routing using our own installation teams
• Installation and configuration of automation: gas sensors, air supply speed controllers, emergency switching systems
• Integration of heat recovery where it is technically justified and does not create a risk of recirculation of harmful substances
• Commissioning, testing and transfer of as-built documentation
• Maintenance of installed systems

Our own installation teams work throughout Kazakhstan: Almaty, Astana, Temirtau, Shymkent, Aktobe and other regions. The design department is headed byKorzhuk Lyubov Ivanovna(Head of the Technical Department), production and supply –Korzhuk Alexey Alexandrovich. Technical support of projects is carried out by Technical Department engineers, includingSemenok Alexander Alexandrovich. Commercial issues and agreement of conditions are in the area of responsibilityKhasanov Ildar Ildarovich(Sales and Project Management Department).

Important: ABL Engineering Group works exclusively with B2B customers – industrial enterprises, scientific organizations, medical institutions and commercial facilities of any size. The company does not carry out ventilation projects for residential premises and private facilities.

Ensuring the safety and compliance of chemical laboratory ventilation requirements

A chemical laboratory is a high-risk facility, where control of the composition of air masses directly determines the safety of personnel. Working with toxic substances, aggressive vapors and harmful gases creates stringent requirements for ventilation systems: they must not only provide air exchange, but also keep the concentrations of hazardous and harmful substances below the maximum permissible levels established by current regulatory documents.

ABL Engineering Group designs and installs ventilation systems for chemical laboratories in strict accordance with relevant standards –SNiP RK 4.02-42, SanPiN and industry regulations on labor protection. Each design solution is tested for compliance with regulatory requirements at the stage of calculating parameters: air exchange rate, rate of removal of contaminated air flows, vacuum level in fume hoods – all this is included in the technical documentation before installation begins.

Key principle: Compliance with regulations is not a formality, but an engineering task. Insufficient exhaust or incorrectly designed air ducts create a real risk of leakage of toxic gases and accumulation of harmful substances to dangerous concentrations.

Our specialists – including the head of the technical department Korzhuk Lyubov Ivanovna and the Technical Department engineer Semenok Alexander Aleksandrovich – provide full documentary support: from initial data to as-built documentation confirming the compliance of the installed system with all regulatory requirements.

• Control of maximum permissible concentrations (MPC)— calculations are carried out for each class of harmful and toxic substances used in the laboratory.
• Compliance with air flow regulations— the rate of air supply and removal complies with the requirements of SNiP and SanPiN for laboratory premises.
• Reduce the risk of hazardous substances leaking— systems are designed taking into account emergency scenarios: zoning, backup exhaust circuits, control sensors.
• Documentary confirmation of compliance— all technical documentation is drawn up in accordance with the regulatory requirements of Kazakhstan.
• Qualified specialists at every stage— from design to commissioning, with quality control of installation work.

Violation of standards in a chemical laboratory is not an administrative risk, but a direct threat to the health of employees. The accumulation of toxic aerosols and suspended particles, exceeding the permissible level of concentration of harmful substances, the absence of an emergency exhaust circuit – each of these factors can lead to an incident. That is why ABL Engineering Group builds systems with a performance reserve and incorporates backup solutions already at the design stage.

Over the years of operation and more than 40+ specialized facilities, the company has developed clear procedures for monitoring compliance with regulatory documents – from the initial audit of the premises to the final inspection of the installed system before delivery of the facility.

Problems and tasks of ventilation of chemical laboratories

A chemical laboratory is an environment where, during technological processes, experiments and chemical reactions, chemicals are constantly formed.vapors and gases of toxic, hazardous substances. Removing contaminants from the work area is not a matter of convenience, but a condition for the safe operation of the facility. Without a properly designed ventilation system, the concentration of harmful substances in the air quickly reaches maximum permissible values, creating a direct threat to personnel and equipment.

The key task of ventilation in chemical laboratories— continuous removal of harmful substances, vapors and gases from the working area, maintaining a normal microclimate and preventing the spread of hazardous contaminants outside the laboratory premises.

When designing ventilation systems for chemical laboratories, ABL Engineering Group engineers work with a full range of tasks typical for production and research facilities:

• Removal of vapors and gases of toxic substances— localization of contaminants directly at the point of their formation: near fume hoods, reactors, reagent bottling areas. This eliminates the spread of hazardous compounds in adjacent rooms.
• Microclimate monitoring— maintaining standardized values of temperature and air humidity in accordance with the requirements of SanPiN and SNiP. Deviations from the norms affect both the accuracy of experiments and the working conditions of personnel.
• Preventing the spread of pollution— creation of directed air flows and low-pressure zones that prevent the migration of harmful substances into corridors, neighboring laboratories and administrative areas.
• Smoke removal in emergency situations— integration of emergency hood, providing evacuation of combustion products and toxic emissions in emergency situations during production processes.
• Neutralization and air purification— the use of filters and scrubbers to capture chemically active aerosols, acidic vapors and fine particles before being released into the atmosphere.

The complexity of the task is determined by the specifics of the technological processes and reactions occurring in the laboratory. Ventilation of a facility where acids are handled differs from systems designed for organic solvents or alkalis. That is why the calculation of system parameters always precedes the selection of equipment.

Compliance with regulatory requirements – SNiP, SanPiN and specialized GOSTs – is not an optional recommendation, but a mandatory condition for putting a facility into operation and passing supervisory inspections. ABL Engineering Group specialists design systems taking into account current editions of regulatory documents, which eliminates comments from regulatory authorities.

The company’s experience at more than 40+ completed facilities shows that most problems with ventilation in chemical laboratories arise not due to equipment failure, but due to errors at the stage of calculating the air exchange rate and incorrect determination of localization points of hazardous contaminants. That is why ABL Engineering Group begins each project with a detailed technological audit of the premises and analysis of the composition of substances used in production processes and experiments.

Technical parameters and characteristics of ventilation systems for chemical laboratories

Designing ventilation for chemical laboratories requires precise engineering calculations: each system parameter is determined based on the hazard class of the substances, the volume of the room, the nature of the technological processes and the requirements of regulatory documents. Technical Department engineers of ABL Engineering Group – in particular, Semenok Alexander Aleksandrovich and Head of the Technical Department Korzhuk Lyubov Ivanovna – perform a full technical analysis of the facility before the start of design.

Key technical characteristics that are calculated individually for each object:

• Air exchange rate— the minimum indicator for chemical laboratories is 6–10 times per hour, depending on the hazard class of the reagents. When working with highly toxic substances, the multiplicity can reach a maximum calculated value of 15–20 times/hour.
• Air handling unit performance— calculated as air flow in m³/hour, taking into account the volume of laboratory space, the number of fume hoods and local suction.
• System pressure— static pressure is selected based on the length of the air ducts, filter resistance and fan characteristics. For chemical facilities, units with increased resistance to aggressive environments are used.
• Airflow speed— in the working area of the fume hood, the air speed must be at least 0.5 m/s, which ensures reliable removal of vapors and gases without turbulent turbulence.
• Temperature and humidity— microclimate parameters are maintained within the ranges regulated by SanPiN: working area temperature 18–22 °C, air humidity — 40–60%. Deviations from the norm are recorded by the automation system.
• Noise level— when selecting equipment, the permissible noise in laboratory premises is taken into account (no more than 60 dBA), which affects the choice of the type of fans and the method of their vibration isolation.

The system is controlled through an automation panel with the integration of automatic sensors for gas contamination, temperature, humidity and pressure. There can be several sensors in the system – their number and location are determined at the design stage. Automation provides continuous monitoring of air quality, switching to emergency mode when maximum permissible concentrations are exceeded, and remote control of all actuators.

Technical methods of air control, used in ABL Engineering Group systems, include: continuous analysis of air composition through multi-gas sensors, cascade control of fan performance based on a signal from concentration sensors, as well as algorithms for automatic transition to maximum power in emergency situations.

Our own production of equipment at the site in Temirtau (2 workshops with an area of more than 1000 m², CNC machine park) allows us to produce air ducts, fan housings and automation elements with characteristics that exactly correspond to the design parameters of the project. This eliminates the discrepancy between design solutions and actually delivered equipment – a typical problem when working with intermediaries.

All technical solutions are developed taking into account the current standardization technologies: SN RK 4.02-105-2014, SanPiN 2.2.4.548-96, GOST 12.1.005-88. Head of Production and Supply Alexey Aleksandrovich Korzhuk ensures that the materials and equipment used comply with the specifications stated in the project – from incoming inspection to final acceptance of the installed system.
