Dear Yasir, ask this question openly, you have asked this question in your project. again post a question but not under the project because all people do not have access to your question.

Hello,

Do you speak about assesment ? Occupational risk, biologic or chemical process ? Tell us more to help you.

 Hello Cecile, 

I need guidance regarding the hazards elimination associated with PSM (Process Safety Management) elements for process industries in terms of Fire, Explosion and Toxic Release.

Hello Yasir,

I am a professional risk prevention engineer for research centers. I do not have projects underway because I have a support function for researchers. I am specialized in chemical and biological risk. I can help you if you describe a little more your project and the chemical substances you use.

 Dear Yasir, 

Your question mentions Hazard Elimination Techniques. In general hazard elimination is not a relevant issue as many hazards are simply present as a result of substances (raw materials and products) choices, process choices, equipment design, the environment in which the operation is planned, etc.

Hazard identification is the first step, for which tools are available, such as BowTie based investigation (https://www.cgerisk.com/knowledgebase/The_bowtie_method). Based on  the identified hazards and possible control and/or mitigation measures the remaining risks must be determined. This means that for specific hazards (fire, explosion / detonation, run-away, intoxication, fatalities, soil / surface water / ground water pollution, falling from height, high/low pressure, wrong product quality, process changes, poor maintenance, etc, etc) specific expertise might be required. A major part of my job is

The crucial question in Process Safety Management processes is identifying the acceptable level of risk. However low the risk can be made, there will always be a residual risk which might result in catastrophic incidents.

Based on many incident investigations and PSM studies I have been involved in, my experience is that incidents do happen, but the severity of the incidents must be reduced as reasonable as possible. This also means that safe rescue activities (fire brigade, medical services, etc) after a calamity should also be taken into account.

From my website (www.doktersadvice.com):

Basis for Risk Management in general are the following steps:

 • Know the hazards and threats that may cause problems for both activities and organization

 • Identify events that may jeopardize the normal operation

• Inventorize the available controls that could prevent or limit undesirable events and ensure proper functioning of these controls (prevention).

 • Identify consequences of the most threatening events.

 • Inventorize protection and mitigation measures/defenses that might limit the consequences (repression).

 • Take appropriate actions (including incident analysis) to ensure that all controls and defenses are functioning as intended.

Hi Yasir,

In process Industries, Process upsets are the major risk. In the process safety management, The important elements which needs to be considered are

1. Process Safety Information - Getting all the information with respect to Process Design basis, equipment basis and material basis - In this process safety studies play a vital role in providing critical information about process behaviour

2. Assessing the risk through PHA and take appropriate mitigation measure

3. Management of Change with respect to technology, Facility and personnel

Muhammad Yasir Shamim hazards are not related to PSM elements, hazards are associated with process itself or the chemicals in the process. PSM is used to avoid or minimize these hazards by managing. So pls elaborate what actually is your aim
