LEV Proficiency Modules

P601


Commissioning and Thorough Examination and Testing of Local Exhaust Ventilation Systems

 
Aim:
To provide the methodology, theoretical and practical knowledge to enable the student to proficiently:
 
  • Show awareness of the principles of good control practice and the role of local exhaust ventilation (LEV).
  • Carry out commissioning of an LEV system and establish whether the system works effectively and controls exposure.
  • Determine the operating criteria for continued performance to specification.
  • Carry out the testing of previously-appraised LEV systems used to control exposure to substances hazardous to health.
  • Produce suitable records of the results of examination and testing as required by regulatory guidance and codes.
  • Understand and be able to describe the principles and the main elements of an LEV system.
  • To judge whether an LEV system is capable of adequate control of the identified hazards.
  • Carry out the necessary measurements safely to determine if an LEV system is effective and operating to the design specification.
  • Provide suitable advice to remedy any faults discovered.
Prior Knowledge:
Candidates for this course are expected to have some basic knowledge of the components of ventilation systems and their purpose and be aware of the contents of HSG 258 (2008) Controlling Airborne Contaminants at Work.
 

P602

Basic Design Principles of Local Exhaust Ventilation Systems

Aim:
To provide the basic methodology, theoretical and practical knowledge to enable the student to proficiently:
  • Demonstrate awareness of the principles of good control practice and the role of local exhaust ventilation (LEV).
  • Understand the importance of design considerations in terms of the workplace, process, and plant, as a means of reducing occupational exposures.
  • Understand the principles and the main elements of an LEV system and be able to design basic LEV systems that will be capable of adequately controlling the identified hazards.
  • Know how to carry out the necessary measurements at commissioning of a system and to check whether a local exhaust ventilation system is effective and operating to the design specification.
  • Provide suitable records of the basis of design.
PriorKnowledge:
Candidates for this course are expected to have successfully completed module P601 or can demonstrate equivalent knowledge. They should also have a good understanding of the contents of HSG 258 (2008) Controlling Airborne Contaminants at Work.

 

P604

Performance Evaluation and Management of Local Exhaust Ventilation Systems

 
Aim:
 
To provide the theoretical and practical knowledge to enable the student to:
 
·         Understand the basic principles of how airborne contaminants are generated by industrial processes, how this impacts on the control strategy, and how the performance of control solutions can thereby be evaluated and optimized.
·         Understand the importance of design considerations (in terms of the workplace, process, and plant)  in reducing occupational exposures.
·         Recognise the range of approaches to risk reduction embodied in the hierarchy of control
·         Understand the principles and the main elements of an LEV system and understand the basic design features of LEV systems to facilitate adequate control of the identified hazards.
·         Recognise the limitations of local exhaust hoods and enclosures and the means to optimise their effectiveness.
·         Understand how to carry out the necessary measurements to assess whether a local exhaust ventilation system is effective and operating to the design specification.  
·         Understand the principles and methods of air sampling  and interpretation and limitation of results
·         Be able to determine either qualitatively and quantitatively as appropriate  whether an LEV system is capable and achieving adequate control of the identified hazards
·         Be able to diagnose the likely causes of poor system performance, and provide suitable advice to remedy any faults discovered.
·         Determine the operating criteria for continued performance to specification and Develop a testing criteria for routine maintenance checks. Have the ability to Advise on appropriate user pre use checks and user training.
·         Produce commissioning reports, user manuals and system log books to retain suitable records of the results of examination and testing as required by regulatory guidance and codes.
 
Prior Knowledge:
Candidates for this course are expected to have some basic knowledge of the components of local exhaust ventilation systems and their purpose and have taken proficiency module P601 or have equivalent knowledge and experience. They should also have a good working knowledge of the contents of HSG 258 (2008) Controlling Airborne Contaminants at Work.
