(48ae) Understanding the Complexities of Process Safety

Process safety – it’s a simple name for what is actually a complex process concerning an entire system of safety procedures within potentially dangerous facilities such as chemical plants, processing refineries and other similar facilities. From the design of the equipment to be used in these facilities to the inspection and maintenance, proper practices must be in place to ensure a safe working environment for all.

There is often a lack of knowledge regarding process safety among professionals working in hazardous locations industries, especially with regard to the safe operation of electrical equipment. This can be a serious problem, posing a threat to the safety of the facility as well as the personnel working in and around them.

So, what do these professionals need to know about process safety? Keeping up with applicable industry codes and standards is critical. Globally, standards developed by the International Electrotechnical Commission (IEC) and ATEX directive govern the industry. However, the U.S. has been reluctant to adopt these requirements, and instead abides by a number of National Fire Protection Association (NFPA) codes that pertain directly to explosive atmospheres. These include National Electric Code® (NEC) 500 and 505, among others.

According to these codes, environments that generate potentially explosive atmospheres are classified into different divisions or levels of potential danger based on the likelihood and duration of the explosive atmosphere’s presence. In addition, the codes divide the divisions/levels of potential danger into sub-groups based on the type of hazard contained in the atmosphere.

Depending on the division, sub-group and type of equipment, specifications vary and different protection performance operations are required. The NFPA best practices advise qualified personnel to perform periodic inspections, tests and services to ensure equipment is properly maintained. These professionals should be familiar with all electrical installation requirements and trained to evaluate and eliminate ignition sources.

Complex and difficult to understand, it’s no wonder hazardous locations professionals have difficulty keeping up with the classification system and the rules for safe operation outlined by the NFPA and NEC. However, these codes are in place to ensure a safe working environment for all, and it is imperative that personnel are able to demonstrate full comprehension.

During this presentation, Wayne Mayo, technical training specialist for hazardous locations at Intertek, will help attendees understand how to meet necessary regulations and enhance efficient and reliable operations. Through increased comprehension of NFPA guidelines, attendees will be able to determine the safety requirements and process controls needed to meet industry expectations, minimize hazards and increase worksite safety and optimal productivity.
