A Note From Our President

Since 1995, design safety engineering has focused on helping companies to improve the safety of products, equipment, machinery, and facilities through design. A primary method to achieve safety through design is the risk assessment. To stay on the leading edge of design safety methodologies, dse has been actively involved in national (ANSI) and international (ISO) standards development, eventually assuming leadership roles in these activities. dse delivers the latest knowledge and methods from this involvement to the customers we serve through books, technical presentations, training and our designsafe risk assessment software.

We are actively involved in the Prevention through Design activity sponsored by the US Centers for Disease Control and dse holds membership and leadership positions in the following standards development activities:

• ANSI B11.0 Safety of Machinery - Chair
• ISO 12100 Safety of Machinery – Convener (Chair) via ISO TC 199 / Working Group 5
• ANSI/PMMI B155.1 Packaging Machinery Safety Requirements
• ANSI/RIA R15.06 Safety requirements for Industrial Robots
• ANSI B11 Machine Tool Industry – Chair of the Accredited Standards Committee
• ANSI B11 TR7 Designing for Safety and Lean Manufacturing – Chair
• ANSI B11.19 – Performance requirements for risk reduction measures
• ANSI B11.25 – Safety Requirements for Large Machines - Vice Chair
• ANSI B11.26 – Functional Safety
• ANSI/ASSE Z590.3 Prevention through Design – Vice Chair
• ANSI/ASSE Z244.1 Control of hazardous energy – Vice chair
• ISO Guide 51 – Safety aspects – Guidelines for their inclusion in standards
• ISO 13849-1 – Safety-related parts of control systems, ISO TC 199 / Working Group 8
• ISO/TC 39/SC 10/WG 2 – Grinding machines
• ISO TC 313 Packaging Machinery – US TAG – Vice Chair
• NFPA 79 – Electrical Standard for Industrial Machinery

We continue to advance our knowledge, hone our expertise, and improve the tools in our toolbox through practical application of risk assessment and safety through design in the real world.

Admittedly, the risk assessment process can be painful, and dse applies what we've learned to help helps minimize the pain and the time it takes to complete risk assessment. Risk assessment is not an academic or theoretical exercise to dse. We get our hands dirty in the trenches helping clients and customers through the risk assessment process. We understand our clients are very busy and that risk assessments need to be done well and efficiently.

Through our involvement in products liability and safety litigation, we see first-hand the consequences of decisions made about risk and risk reduction, and the positive and negative impacts that the language in industry standards has on plaintiffs and defendant companies. We apply these lessons learned to our software tools, presentations and training to feed forward the results so that injuries are not repeated.

We enjoy and greatly value our long-term relationships with existing customers and clients, and we look forward to working with new companies where we can assist. We especially enjoy drinking scotch and blogging.

Thank you for your interest and we look forward to working with you.
