Assessment and risk control

download (3)


Risk is everywhere, in any daily activity. If you want an efficient and safe work, it’s better to conduct a risk analysis. TCS HANOI would like to share with you some following experiences.

What is risk analysis?

Risk analysis is a process in which we study about risks probably related to your work; determine in details those risks, set up control activities in order to perform that work most efficiently and safely and to avoid any accident, any asset, facilities and environment damages.

When we should conduct a risk analysis?

At any time, before performing any work, we can conduct a risk analysis for that. Example: we intend to move a glass from this table to another one. What can be happened during movement? Is the glass hot? Is a hand – on sharp? Is water plenty? Is there any stuck during movement? .v.v.

Who will conduct a risk analysis?


People who participate in a risk analysis process should understand principles and sequences of analyzing. In addition, that people should experiment in the work which he will analyse. A risk analysis cannot be perfect if it is prepared by one or two persons. At least, there should be from three to five members who join into that project. That group should be required about working plan knowledge, mechanical, electrical, chemical, medical knowledge….

  1. Split the work into different steps

You should split the work into different steps following its sequence. Splitting should not be too in details so you can forget the major steps. But it should not be too general so you can miss necessary or predictable steps. Those steps should be clear and directly related to each event and also to dangers what could be happening or will happen during process.

  1. Danger awareness, danger level determination

What is danger? Anything that can injury, frustrate, destruct environmentis danger. Danger can be visible or invisible. In general, tools, machines .v.v. can be considered as dangers, and its consequences are following concerns.

Danger level:If we compare between one motorbike at speed 50km/h and one car at same speed, it is clear that the car is appeared with a danger level higher than motorbike. Or we do comparison between 2 different speeds of the same car; we instantly state that the car at higher speed is more dangerous than the lower. Moreover, if the car in accident that carry more peoples than the other will be more dangerous than the fewer in accident.Hence, danger level is the consequence causing by an incident or an accident.

Danger frequency:When I across a road less crowed I’m safer than across a road much crowed. If number of vehicles is big, probability of accidents is higher. In the same way, if I do something many times in certain time, danger frequency is in direct ratio to the times that I’m in touch with working tools or to danger of that work.

What is risk?

Risk is combination between danger level and its frequency.

Risk = Danger level x Frequency

  1. Question commonly in use during risk analysis:

  • A popular principle: Who? What? Where? When? And How?
  • Is it critical to do this or that work?
  • It has ever been done, hasn’t it?
  • Is there any other way to do this work?
  • Who will join in doing this work? Ai
  • Is there any special requirement about physical or health conditions of people that will do this work?
  • Which tools or equipment will relate to process?
  • When does work start and end?
  • Will time and weather condition take effect to process?
  • Is there any other work that will be performed at same time?
  • What are technical requirements for this work?
  • How about communication?
  • What happen if changing work process?
  • What is danger visible at working area?
  • What is danger probably occurring during work in progress?
  • What is danger invisible probably occurring when work is impacted by relative actions?
  • Impact level of dangers to work, people in charge and working environment?
  • How we can isolate dangers already recognized?
  • How to prevent or minimize dangers to people in charge and also to working environment?
  • Who is responsible for taking actions?
  • Protected equipment if for whom? Details of technical requirements.
  1. Measures of risk control:

Rui ro

There are a lot of measures of risk control. However, risk analysis team will choose most suitable measures base on situation and condition in details of working area and of specific work. Measures can be different but we should comply to different following priorities in order to choose the best measure:

  • Isolation: Please isolate dangers to working area so we avoid being in touch with them
  • Replacement: Please replace dangers by others conditions, equipment safer….
  • Manufacturing: Please maintain, provide extra equipment or protection mode upon in touch with dangers.
  • Policy: Issuing a policy or a regime and a suitable working time.
  • Providing personal protection equipment (PPE): PPE is always the last measure while the others choices are already considered and processed. Should remember that PPE is necessary but it cannot protect you completely.
  1. Risk analysis dashboard:

Risk analysis should be written clearly, if necessary it should be translated to language which participator can understand. Risk analysis dashboard should mention clearly each unit of work, time and location of process. It should mention clearly visible/invisible dangers that can impact to work process. Those impacts are at which level, who will be impacted…v.v. It should state clearly names of participators and also authorized approvers..v.v.


Risk analysis is an important procedure while doing a complicated work or work at high risk level. Risk analysis dashboard is connection about safety between stakeholders. Please conduct a risk analysis for your specific works. If your works is repeated at different period and in different location, your dashboard should be restudied and updated. Above is only TCS Hanoi general guidelines about risk analysis./.
