Hazardous Area Classification
Method of analyzing and classifying the environment where explosive gas atmospheres may occur so as to facilitate the proper selection and installation of equipment to be used safely in that environment. This process allows for preparation of safety procedures for plant operation and maintenance. The area classification process also reduces the overall installation risk level.

Turnkey P&ID with Mechanical Identification
The combination of our mechanical identification and technical drafting services makes MSI a single source of responsibility for the most critical aspects of any process safety management and risk management program. Our ability to integrate our mechanical identification products on piping and components coinciding with facility P&IDs means HAZOP personnel can quickly and easily identify process issues prior to emergency response. By utilizing this integrated approach, this combination of products and services provides great value and many benefits to risk assessment teams, new and existing maintenance personnel, and contractors.  

Emergency Evacuation Route Plans
The emergency evacuation route plan serves as a valuable and readily available guiding tool for the occupants and outside emergency responders during an emergency. Plans are posted throughout the facility and include information such as your location, directions to the exit(s), locations of fire protection and safety devices and brief emergency procedures.
