Risk Responsibility & Risk Management

   
  

Warning
All herein after risks are serious actions that may damage the instruments, affects patient health or user health, and can be danger for patient health and life. All actions should be taken to reduce such risk..It is the user responsibility to repoty for any incidence or near incidence to the manufacturer as immediate action.

   

Energy Hazards

Risk Estimation Of Risk Risk Reduction Evaluation Of Risk
Heat Can effect product shape and cause scale

Correct use of temperature
and use of electroplishing,
acid pickling, Ultrasonic
cleaning and passivation technique.

Hazard related to heat is minimized.
Mechanical force Causes change in shape, damages the blade and cutting ends and other unnecessary load strike cause effect on product damage.  Correct use of forging load, proper use of machines and care in storage reduces the risk.  Proper storage and expert workers are used to avoid the above risk.
Moving parts All moving parts are functioning and there is unnecessary friction for damaging the device. Proper half-moon, box and other accessories are manufactured and prepared for reduction in risk. Cutting test, Strength stability and boil test are conducted for evaluation of the risk.
Suspended mass Can cause rust in the form of contamination Use for the required purpose and apply preservation techniques such as, oiling and Passivation to minimize the risk. Clean the instrument in ultrasonic cleaner during manufacturing and Clean the instruments as per instructions during operation.

Responsible

Bio contamination Can cause rust on the device due to hand sweating, chloride atmosphere and tap water, Bacteria, Ammonia gas

Avoid the atmosphere of ammonia gas, chloride ions, tap water.Use gloves during operation to avoid hand sweating having the particles ofHydrogenSulfide

Check the instruments with the help of boil test. Apply some force No rust No indication of stress corrosion cracking.  User
Bio incompatibility Color change and black deposits appear due to clotting of blood on the device.Some bacteria and chemicals also produce different color. Tap water has also effect for producing fade color and affecting the life.

Do not put the devices in blood during operation. Always clean with distilled water after operation. Avoid the instruments from dust and other contamination. Properly preserve the instruments.

Check that there is no deposits of any color due to dust or contamination. No depositsNo rust  User
Incorrect formulation (Chemical composition Damage of the devices .Effect on the life of the devices. Dirty devices.Misuse of the devices. Damage during operation. Effect on patient health. Use material for devices as stated in ISO 7153. Use Chemicals of suitable concentration for Acid pickling, Electro polishing, Ultrasonic Cleaning etc. Proper hardness for better working and functioning. Mill test CertificateChemical Composition ReportBoil Test Report Hardness Test Report No rust Good functioning Manufacturer
Toxicity Depletion of Chromium layer can cause toxicity stainless steel is corrosion resistant because it has chromium oxide layer that prevents it from rust and corrosion and if the solution of high pH is used then this solution or detergent strengthens on the surface of the instrument and during sterilization in the autoclave the detergents or solution strengthens by the effect of heat and also removes chromium oxide layer and as a result of the removal of chromium oxide layer, corrosion occurs. pH of the solution and detergents must be maintained in between the range of 6.0 to 8.0. Proper techniques of Autoclaving and Sterilization No rust User
Cross infection Can damage health and can create a danger for life. Instruments should be sterilized every time before using it for next operation.(Line start-up inspection) No damage and infection Good functioning of the instrument. User
Inability to maintain hygienic safety Rust Reduction in device life Danger for patient life Use proper safety instructions as given at the end of this chapter. All environment control and safety hygienic conditions are followed. Log time use of the device. User
Degradation Improper functioning Damage in patient health Properly stored All safety conditions are followed. Instrument is working properly, having required surface level and shine.Easy to use Good functioning of the instrument. user

 

   

Environmental Hazards

Risk Estimation Of Risk Risk Reduction Evaluation Of Hazard
Responsible
Likelihood of operation outside prescribed environmental conditions Can cause rust, damage, infection, reduction in life of the device and patient Severe injury

Proper hygienic conditions Provide protection equipment and good atmosphere.

There is no contamination and dust. All controls are checked and verified. User
Incompatibility with other devices Due to high hardness and heat effects, device can damage / break suddenly.Breakage

Use proper specification for getting required hardness. Use sterilization solution having pH in between 6.0 to 8.0

Hardness test report Check the pH of the solution with calibrated pH meter Manufacturer and customer
Accidental mechanical damage Due to high hardness and heat effects, device can damage / break suddenly.Breakage

Use proper specification for getting required hardness. Use sterilization solution having pH in between 6.0 to 8.0

Hardness test report Check the pH of the solution with calibrated pH meter User
Contamination due to waste products and /or device disposal During production, Some foreign particles like chips, chemicals, dust, oil, lint contaminate with the product that causes problem after complete processes. The above particles are the source of instrument staining,, spotting , corrosion and other potentially damaging conditions. Other effective measures are also being documented here. Water also produces mineral deposits which are the cause of corrosion

To avoid the above problems. Instruments are ultrasonic cleaned with the validated time. The frequency of ultrasonic cleaning process depends upon the design and manufacturing techniques of the product., as mentioned on related quality plans. The effectiveness of ultrasonic cleaning process depends upon the time used as determined by validation of the process. Water mineral composition changes from one locality to another locality and it is the basic cause of stain, spot, corrosion and discoloration of instruments. so, to solve the problem created by water, always use deionized water.

Verify that the shape, surface, fitting and setting of devices and Boil test reports showing the result as OK. User

 

   

Hazards Related To Use On The Device

Risk Estimation Of Risk Risk Reduction Evaluation Of Hazard
Responsible
Inadequate labeling Change the label after consulting with Manufacturer Co. (Pvt) Ltd.

Distributor must properly check the label according to requirement of the directive

Manufacturer should recheck before pasting the label on the device. Manufacturer
Inadequate warnings instructions Can cause death or injury due to improper use of the device.

Only relevant person should use the device.

Check that label has warnings, precautions and administration of the device. Manufacturer
Inadequate specification of accessories Accessories having different design feature or with wrong material cause inadequacy for device operation.

All accessories / drawings should show complete dimension and tolerance control.

Check that related drawings show all necessary dimensions and accessory is completely fit in the device. Manufacturer
