Air flushing provides an efficient method of removing debris from pipelines and newly constructed systems. ∴ In the gas process lines, the velocity should be the lowest figure between 60 m/s and the velocity obtained at 1.3 time the maximum process flow rate. The minimum velocity should be 30 m/s. In liquid process lines, a…
01. Air Blowing Test Air Blowing can be used as a safer, more environmentally friendly and cost effective alternative to conventional cleaning and steam blowing. The purpose of air blowing is to remove loose scale and debris prior to start up using compressed air as the cleaning medium. The velocity of a large air mass…
A Job Safety Analysis (JSA), also known as a Job Hazard Analysis(JHA), is to identify hazards before they occur. It is on the relationship between workers, tasks, equipment, devices and working environment. After you identify uncontrolled hazards, you should carry out four steps to eliminate or reduce it to an acceptable risk level. ∴ 1. Select…
JOB SAFETY ANALYSIS (JSA) is a systematic process that breaks down a job into a sequence of steps, identifies hazard in each step, evaluates the actual and potential risk of the hazard and establishes risk control measures. Work Method Statement (WMS, Method of Statement) is a document detailing how a particular task or activity will…
