Established for over 11 years, Gully Howard Technical are experts within our fields, ideally placed to offer the W505 – Control of Hazardous Substances training course. Our trainers are both highly knowledge and professional, with vast experience delivering Occupational Hygiene Training worldwide.
The W505 – Control of Hazardous Substances is a core module under the Occupational Hygiene Training Association (OHTA) international qualification scheme. BOHS are the UK examining board for this module and Gully Howard Technical are the course providers. Candidates will take an open book written examination at the end of the module, and complete an assessed practical during the course. View the W505 course syllabus here.
The W505 – Control of Hazardous Substances Training course aims to describe the ways in which exposure to hazardous substances arises in the workplace, and to introduce the methodologies and technologies available to control exposures and thereby reduce risks to health.
On successful completion of this module the student should be able to:
- Describe how airborne contaminants are generated by industrial processes, how this impacts on the control strategy, and how control solutions can thereby be optimised.
- Recognise the range of approaches to risk reduction embodied in the hierarchy of control and select appropriate strategies for implementation.
- Describe the meaning of “adequate control”, particularly in relation to personal exposures.
- Discuss the importance of design considerations in terms of the workplace, process, and plant, as a means of reducing occupational exposures.
- Describe the principle elements of a local exhaust ventilation system, give examples of typical installations and how to carry out the necessary measurements to assess whether a local exhaust ventilation system is effective and operating to the design specification.
- Recognise the limitations of local exhaust hoods and enclosures and the means to optimise their effectiveness.
- Describe how personal protective equipment programmes may be used in an effective manner.
- Recognise the impact that control measures may have on other workplace hazards and understand the need to take a holistic approach to the design of control solutions.
