1. Scope
This risk management is carried out for EsCom100 to identify the hazards associated with medical
devices, to estimate and evaluate the associated risks, to control these risks, and to monitor the
effectiveness of controls. This report is applicable to all stages of the life-cycle of a medical
device in accordance with ISO 14971:2007.
2. Definition
○ Harm: Physical injury and/or damage to health or property.
○ Hazard: A potential source of harm
○ Hazardous situation: Circumstance in which people, property, or the environment are exposed
to on or more hazard(s)
○ Risk: The probable rate of occurrence of a hazard causing harm and the degree of severity of
the harm
○ Post-production: Part of the life-cycle of the product after the design has been completed and
medical device has been manufactured.
○ Residual risk: Risk remaining after risk control measures have been taken.
○ Risk Analysis: The investigation of available information to identify hazards and to estimate
risks.
○ Risk assessment: Overall process comprising a risk analysis and a risk evaluation
○ Risk control: Process in which decisions are made and measures implemented by which risks
are reduced to, or maintained within, specified levels
○ Risk estimation: Process used to assign values to the probability of occurrence of harm and the
severity of that harm
○ Risk evaluation: Process of comparing the estimated risk against given risk criteria to
determine the acceptability of the risk
○ Risk management: Systematic application of management policies, procedures and practices
to the tasks of analyzing, evaluating, controlling and monitoring risk.
○ Safety: Freedom from unacceptable risk of harm
○ Severity: Measure of the possible consequences of a hazard
○ Verification: Confirmation, through the provision of objective evidence, that specified
requirements have been fulfilled

4. 3 - Estimation of the risks for each hazardous situation(Step 3)
The identified hazards shall be estimated using the criteria below. Reasonably foreseeable
sequences or combinations of events that can result in a hazardous situation shall be considered
and the resulting hazardous situations shall be recorded.
1. Severity
The severity of harm consists of five stages;

Unacceptable risk [Level 17-25]
Investigate further risk reduction [Level 5-16]
Insignificant risk [Level 0-4]
Where the total value of the risk estimation is Green or Yellow Zone, the risk should be reduced to
the lowest level practicable by appropriate risk control. After the risk reduction measures, the risk
shall be evaluated if the measures produce another risk. Only when the medical benefits outweigh all
the identified and residual risk, they can be accepted. Where it is in Red Zone, it must be diminished
by appropriate measures and re-estimated. Otherwise, it cannot be accepted as a medical device.
SPIDENT CO., LTD.
Risk Management Report , Page 17 of 20
5. Risk Evaluation
Step 4. Risk Evaluation
From the estimated hazard data at step 3, we can decide if risk reduction is needed or not. Where the
level is under 4, BAR or under 16, ALARP, it can go step 9 directly. However, the possible risk
reduction can be adopted.
6. Risk Control
6.1 Risk reduction
When risk reduction is required, risk control activities shall be performed as follows,
6.2 Option analysis (Step 5)
The risk control measures shall be used one or more of the followings in the priority order listed.
1. Inherent safety by design
2. Protective measures in the medical devices itself or in the manufacturing process
3. Information for safety
6.3 Implementation of risk control measures (Step 6)
The risk control measures adopted at stage5 shall be implemented and verified.
6.4 Residual risk evaluation (Step 7)
After the risk control measures are applied, the residual risk evaluation shall be performed in
accordance with the same criteria as in step 3.
6.5 Risk/benefit analysis (Step 8)
Decide if the overall residual risks posed by the medical devices are acceptable.
6.6 Other generated hazards (Step 9)
Risk control measures taken in step 5 may have inherent hazard. If any new hazards are introduced
by any risk control measures, the associated risk(s) shall be assessed.
