The Explosive Atmospheres Special Interest Group (Ex-SIG) is responsible for promoting awareness and understanding of Ex matters. Our focus is a set of associated practices and regulations. These areas continue to develop and represent significant challenges for guidance and understanding.
The SIG is authorised to constitute working groups to help fulfil its purpose.
Members & Leadership Team
Membership is drawn from a wide spectrum including end users, regulators, vendors, contractors and consultants, so that we may represent a broad range of interests in safety related matters. Many SIG members also belong to other professional bodies and this promotes an exchange of views and information throughout the discipline.
Additional standing or temporary working groups may be formed as sanctioned by the steering group.
Chair: Harvey Dearden

- The running of the SIG is to be overseen by a steering group comprised of the chairs from the SIG working groups and other individuals (offering useful skills and/or additional network access) that the group sees fit to co-opt.
- The chair of the steering group is to be elected by the group from amongst its members.
- Each working group will have a chair nominated by its members.
- Chairs will be elected for a period of 3 years (or the WG duration if less). Chairs may serve two consecutive terms, but may only serve in that capacity beyond two terms if there is no other suitable and willing candidate.
- The steering group and working groups should be limited in size to the number of people that are appropriate for them to effectively prosecute their business. The size of working groups shall be no larger than agreed with the steering group. If appropriate, additional members may be recruited as corresponding members of the WG.
- The steering group will be accountable to the trustees for the expenses incurred in the management of the SIG, and budgets for the SIG are to be agreed with the CEO.
- The steering group will be accountable to the trustees (via the Learned Society Board) for proper execution of its business in accordance with its terms of reference (which shall be agreed with the LSB).
- Legitimate expenses may be claimed (in accordance with InstMC expenses policy) for steering group and working group management meetings, but not for meetings or events open to the wider SIG membership.
- Criteria for eligibility to join working groups will be agreed with the steering group. Vacancies will be advertised to the SIG membership.
- Working Groups shall devise and implement a succession plan to ensure the appropriate balance and number of team members is maintained and that there is regular turnover of the WG membership.
- Applications for membership of the SIG are welcomed from a wide community of practitioners and other interested professionals. Membership of the SIG is automatically open to any individual member or Companion Company of the InstMC on application, and to other individuals and representatives of corporate bodies by agreement of the chair of the SIG or the chair of any of its working groups. Individuals or companies wishing to join are invited to contact the chair, making clear whether or not they are InstMC members.
