A.P1 EXPLAIN HOW HEALTH AND SAFETY MEASURES IN A SCIENTIFIC ORGANISATION COMPLY WITH
LEGISLATION/ A.P2 DESCRIBE THE POTENTIAL HAZARDS RELEVANT TO DIFFERENT SCIENTIFIC WORKING
ENVIROMENT.
Health and safety measurements in scientific organisation comply with legislation, by having laws and rules put in place
for companies to follow; different institutions will have different rules to follow under the HSE (Health and safety
Executive). The HSE helps regulate workplaces and prevents safety concerns and death from occurring. Laws state that
organisations must have protective measures that will help prevent so to Plan, Assess, organise, control and monitor
employees, customers and others who could also be impacted is a necessity. All Employees should be given special
training that is required to adapt to the workplace and should be aware of any health and safety risks that could occur
during activities if not followed accordingly there will be a cost for both organisation and individuals; include fines,
imprisonment, and disqualification.
In a chemistry lab before every practical is carried out, a risk assessment is produced to ensure safety by a well
experienced, knowledgeable person i.e. a technical team member, the risk assessment should include all possible
hazards that could occur so that there is a calculated risk of health and safety. HSE states when working in a lab all staff
should wear PPE (Personal protective equipment) [1992] because it helps protects employees from health or safety risks
when in a hazardous environment and around dangerous chemical substances to ensure employees are trained
professionally and know how to report/detect faults. PPE can help protect ones respiratory system(lungs) by breathing
in contaminated air, skin from contact with irritant/corrosive materials, the body from extremes of heat or cold and
falling materials that could land on both head and feet and the eyes from splashes of corrosive substances and flying
particles this could be prevented by face shields, safety googles, making sure that it is suitable for the chosen task so
PPE is needed to reduce risk.an example is during an Aspirin practical when dealing with phosphoric acid the scientist
should be fully protected with lab coat, goggles, and gloves so they prevent accidents from occurring as phosphoric acid
is very hazardous and should be handle carefully when being handled, disposable gloves should be worn so that your
skin is not burned and are available in a wide range of material i.e. latex which suits the practical this could be checked
by the risk assessment to how much risk of exposure there could be spill on to you with the safety of gloves you should
be safe but if not phosphoric acid is corrosive/ irritant to the skin can burn eyes and breathing it can cause irritant to the
nose, throat and could damage the respiratory system. One should be taught on who to remove the gloves without
contaminating and irritating their skin.
COSHH (control of substances hazardous to health regulations) [2002] and COMAH (Control Of Major Accident Hazard)
[2015] works with dangerous chemical, liquid substances/biological agents; states that the appropriate training for
employees should be given and taught the risks and to take precautions when dealing with disinfectants and harmful
substances and if a spillage does occur to follow the COSHH rules which state’s all spillages are to be reported to a
senior technician and to follow a risk assessment which will tell you how to reduce the risk, Employers should create a
risk assessment for all chemicals, this should contain PPE, how to carry out substances safely and how and where to
store them, the risk should be a calculated risk of the likelihood of the spillage occurring (probability of y*z) and if it is
contaminates the air or any other substances around to follow the control measures of appropriate decontamination
and disinfection procedures. Mercury is commonly used in college laboratories when using thermometers to check
boiling points and temperatures of chemical substances when in a food test checking temperatures for water when
being heated by a hotplate water should be at least 100 degrees and then to put a test tube of substance X to get your
result you would check using a thermometer which contains Mercury and if the thermometer dropped mercury will cost
10 of thousands of pounds just to get it cleared, if you don’t have the right training and cleaning procedures, using
mercury in an education environment may not be worth the risk of having it on-site. In a practical using a silver bulb
thermometer there is about 1.5-3grams of mercury, which if broken should be handled appropriately and not to be
thrown away into the trash, COSHH states that if less than 2 tablespoons of mercury is spilt you maybe be able to clean
it up, using a kit yourself. If not to 1 st ventilate the room and to keep humans and animals out of the area, where
appropriate PPE example gloves to avoid irritation to contact with the skin and to clean the mercury into an
unbreakable container and to store it into concealed plastic bag 2 one inside another. Dispose all contaminated waste as
