The Safety and Security (SafeSec) Division of ISA exists to help our members grow both professionally and personally through a transfer of information and knowledge. Our committee chairs write brief articles at least twice a year for posting online. We program safety and security related sessions at ISA conferences, maintain a website and two list serves (one for safety, one for security). Short webinars will be coming soon. Simply put, we're providing premier content and access to experts that you won't get anywhere else.
