In this image above it highlights the potential severity ofharm and likelihood of harm occurring in a laboratory or any other workspacehazards.
The image above has a grade a system which instructs the potentialuser of the equipment the types of risks they could be handling, the gradesystem of the hazard is done by accessing the likelihood of the harm occurringgraded from 1-3, and multiplying it by the potential severity of harm alsograded from 1-3. This grading system instructs the potential user of thehazards he will be encountering ranging from 1 being the lowest and 9 being thehighest. The Table Below will analyse the type of equipment’s we’vehave been introduced to by the risk assessment technicians in the laboratoryroom RVMB036. As shown in the table below it analyse the types of hazards whichoccurs for example, abrasives, noise, cables, airborne dust particles, ventilation,manual handling etc. Protections in place for these hazards were emergency stopbuttons for encase of a fire, demonstrations and supervision by the technicians,fully displayed regulation of equipment, cables were tucked out of the way.These are very simple insurances that the individual’s cooperation is obligedin order to avoid the hazards from occurring.
Majority of the equipments in thelaboratory is graded as level of risk of 1, these hazards are well controlledand contained which is why supervision isn’t needed, its mostly trivial andincase of it happening simple precautions made to prevent it from leading to aserious risk.From the examples above which is most likely to occur in alaboratory when can take the example of noise from a particular equipment,which could lead to severe hearing damages which has been graded of outcome of2 which is tolerable, in the laboratory it has been evaluated that thisparticular cases won’t be an issue because it’s high unlikely to occur becauseof the preparations that has been used to prevent this risk to develop all theequipment’s are highly experimented on and passed the health and safetyregulations to fully reduces future risks. But even though the laboratory takesextra precautions to allow the individual tocomprehend the unlikely risks they’ll beencountering in using this particular equipment. It also advisedto even further reduce the risk the individual should cover their ears with specialtype of head equipment. Another example of hazards which could most likely occur inthe laboratory which is graded to be 3 which is moderate is the use of theequipment such as abrasives, cables, fire. The use of these needs special attention and supervision which whyits grade to be 3. In the case of a fire there’s many safety precautions whichis undertaken to fully reduce a serious risk such as different labelled fireextinguishers depending on the type of fire, also other precautions such as quicklyand safely exiting the laboratory is encouraged to stop further risks, leftaround cables is also encouraged to be safely removed because it could cause injuryto an individual.
In the laboratory the most dangerous type of hazard to occuris graded to be 4 which is also moderate The table shows some hazards that havea risk level of 4, including machinery and water. These hazards have a higherrating than those with a level 3 rating because they are more likely to occurthan those above, but could also be harmful if they were to occur. There areexisting precautions for these hazards including signage, emergency stopbuttons and protective clothing, and also designated areas for certainactivities such as hand washing. Further precautions that can be taken in thefuture can include supervision to make sure machinery is being used correctlyand that all machines and taps are turned off after use.
