Example of HAZOP Cooling Coils Monomer Feed Refer to reactor system shown. Cooling Water

Example of HAZOP Cooling Coils Monomer Feed Refer to reactor system shown. Cooling Water to Sewer Cooling Water In T C Thermocouple The reaction is exothermic. A cooling system is provided to remove the excess energy of reaction. In the event of cooling function is lost, the temperature of reactor would increase. This would lead to an increase in reaction rate leading to additional energy release. The result could be a runaway reaction with pressures exceeding the bursting pressure of the reactor. The temperature within the reactor is measured and is used to control the cooling water flow rate by a valve. Perform HAZOP Study 22

TERMINOLOGY RISK � � � The combination of the likelihood and severity of a specified hazardous event occurring. Risk = Likelihood x Severity LIKELIHOOD is an event likely to occur within the specific period or in specified circumstances Severity is outcome from an event such as severity of injury or health of people, or damage to property, or insult to environment, or any combination of those caused by the event.

TERMINOLOGY DANGER � Danger explains relative exposure to the hazard. It shows the tendency of a hazard hit / struck an employee in a risky situation. Examples: Employees who regularly handle chemicals will be more vulnerable to the dangers of the chemicals than other employees who rarely do. More concentrated sulfuric acid is more dangerous than the sulfuric acid was diluted, so the risk is higher for workers handling the concentrated acid compared to workers who

HAZARD IDENTIFICATION METHOD TO IDENTIFY HAZARD 3. Measurement of the atmosphere, monitoring the environment or medical surveillance of workers. Exposure monitoring: Monitor working area by personal monitoring (monitor of noise, heat, radiation, air contaminants, chemicals etc. ) Biological monitoring: Biological monitoring is a regular measuring activity where selected validated indicators of the uptake of toxic substances in the human body are determined in order to prevent health impairment. Monitoring by examination of, four example, blood, urine, saliva and expired air. Medical Surveillance: Health Surveillance is warranted if substance is used in workplace; substance is hazardous, evidence or reason to suspect injury and atmospheric monitoring insufficient

HIRARC PROCESS RISK ASSESMENT Approach: � Qualitative Risk Assessment: A qualitative analysis would use a scale of "Low, Medium, High" to indicate the likelihood of a risk event occurring. Example: HIRARC � Semi-Quantitative Risk: Used to describe the relative risk scale. � Quantitative Risk Assessment: requires calculations of two components of risk (R): , the magnitude of the potential loss (L), and the probability (p) that the loss will occur.

CONCLUSION � Hazard identification, risk assessment, control and review is not a task that is completed and then forgotten about. � Hazard identification should be properly documented even in the simplest of situations � Risk assessment should include a careful assessment of both likelihood and consequence. � Control measures should conform to the recommendations of the hierarchy of control. The risk management process is an on going one.
