What is your role in Powder Containment?
My role is to work with manufacturers to reduce the health risks to workers when working with particulates and powders. It can include assessing and documenting the risks for a specific material and proc-ess, prioritising the problems and finding cost effective solutions. Materials can be very different in their potential to harm. Particle size, dustiness, the process, equip-ment, amount of material, how many and what manual operations are done can be different for different products. These things affect the potential exposure. If there isn’t much experience of successful dust problem solving in a company it adds
uncertainty. Talking to a specialist can help to keep costs down and make sure that industry standard solutions are considered
Who is the Powder Containment course aimed at?
It’s aimed at people who work in indus-tries using organic or inorganic particu-lates, mixtures, blends or powders in their processing as raw materials, intermediates or products. They may be managers, supervi-sors, safety, engineering or other technical staff making the business case for change, responding to process developments and/ or providing and installing solutions.
What are the themes of the Powder Containment course?
The main themes are; perceptions and consequences (for example, did you know that flour dust can cause asthma?), capture and containment, equipment selection and performance expectations.
Fire and explosion risks are mentioned but not dealt with in any detail. There is a separate in- depth one-day course available on this topic entitled Dust Explosions – how to manage DSEAR/ATEX compliance. There are also sections on this important subject included on the Biomass Handling, Feeding and Storage course, as well as briefly on the general Overview of Particulate Handling Technology course.
What can participants expect to see and do?
Attendees often come from very differ-ent industries. We encourage participation and ask attendees to share their issues and offer ideas for solutions.
We look at some different risk assess-ment approaches including the UK H&SE 5 step approach, a case study and HSG258 for airflow capture systems.
Barrier systems are reviewed for higher risk materials with the opportunity to discuss points
of weakness and look at the impact of ergo-nomics on design and how worker behaviors’ can affect the airborne particle level.
There is a tour of the Wolfson Centre pilot plant and a chance to meet senior staff. Powder blockages and flow problems can lead to releases of powder when lines are opened to clear them or equipment fails. Sometimes solving an underlying process-ing or equipment problem means airborne powder issues can be eliminated.
There is a surgery for individual advice at the end of the day.
With so many training courses available, why should people attend a Powder Containment course?
For powders and particulates ‘the devil is in the detail’. Understanding is often built up over time by experience in the workplace. Industry and regulators now expect a faster, more accurate and cost effect response to problems as Health and Safety is involved. This course gives a good grounding, provides tools for immediate use and references and contacts for follow up questions.
What are you most excited about for Powder Containment?
Every course brings a new mix of industries so I always learn something new about a dif-ferent set of materials, products or processes. It is good for people to realise that others have similar problems and that solutions can cross over between different types of industry where they may be tried and tested.
How has the Powder Containment course changed and developed?
Course numbers are limited to allow time for discussion and sharing of experiences and concerns. The location is the Medway campus of the University of Greenwich at Chatham Maritime in Kent.

The MULTIDOS® L is available both as an open design or with a dustproof housing variant and can be supplied in standard designs or in special designs for a host of different industry sectors. This weighfeeder is an individual, customised solution for any application.The MULTIDOS® L is available with a hygienic design which satisf ies the most stringent hygienic requirements of the food industry with FDA certified product contact parts. For example, the weighing module is very easy to dismantle and assemble, saving time and effort for frequent cleaning intervals and wet cleaning. All relevant parts for cleaning are secured with easy to use plug connections. The casing can be taken off and the mechanism removed to the side.
