1Answer 1Risk analysis is one of the science that deals with risks, their probability and evaluation (Aven, 2015). The risk assessment and management is carried out for each project as a part of risk analysis. Risk occurs when someone is exposed to hazardous conditions that may cause injury and severe health problem. There are several methods to identify the hazards like HAZOP (Hazards and Operability problems) method (Dunjó, et al., 2010). It is a systematic approach to identifying risks and its operability problems across the entire facility. This kind of method is useful in identifying unwanted hazards designed into facilities due to lack of knowledge or caused due to changes in the process or operating conditions into the preexisting installation. Apart from HAZOP, there are other methods to identify the hazards such as “What if,” Checklists, Task analysis, etc. HAZOP analysis is carried out by a multidisciplinary team with team structure involving two kinds of members one is of the technical background while other is of supporting role. In HAZOP criticality analysis, the relative importance of each failure effect isquantified so that risk factors could be reduced. In this assignment, we would discuss the hazardsassociated with the chemical industry and its management. There are several risks associated with the chemical industry such as exposure to hazardous/poisonous chemicals. Such risks could happen due to spillage, splash, inhalation, etc. which could be due to leakage. One of the known examples for leakage is Bhopal gas tragedy. Apart from exposure to the chemicals are tenable to explosion or fire that is not just because of flammable fluids but could also be done due to a blastin pressurized chemicals or uncontrolled reaction. Another potential hazard that could be overlooked in the chemical industry is an electrical hazard that can also be caused by static.

2Answer 2:Hazard identification (HI) is a major step as the company is looking for the modifications in the plant. The first phase of HI would start with planned site inspection, with an idea to identify any gaps in the implementation. This review includes surveys on preplanned lines, of process hardware and methods along with the interviews with field staff and operators. After that a checklist is prepared to evaluate the equipment, resources or events during the installation. Task analysis is carried out to know all occupations and jobs establishing the work efficiency and hazards related to any of the successive steps. As a risk identification, HAZOP method was used which is a rigorous and widely accepted technique for it. The following questions will be considered for expert HAZOP analysis.• Plant’s design intention • Deviations from the plan, if any? • Cause of deviation • Outcomes of such deviationThe exact method of implementation of HAZOP varies according to the demand. As the detailed plan has been made to the piping and instrumentation diagram phase, the outline, workouts and first standard operating procedures are prepared, and HAZOP can be undertaken formally. This action plan is subject to detailed and projected reviewing by a team with varying backgrounds. It should always be remembered that HAZOPs are intended to identify the problem, not for solvingthem.
