Health and safety in science organisationsCOSHH:
COSHH is the law that requires employers to control substances that are hazardous to health. You
can prevent or reduce workers exposure to hazardous substances by:
finding out what the health hazards are;
deciding how to prevent harm to health (risk assessment)
providing control measures to reduce harm to health
making sure they are used
keeping all control measures in good working order
providing information, instruction and training for employees and others
providing monitoring and health surveillance in appropriate cases
planning for emergencies.
Most businesses use substances, or products that are mixtures of substances. Some processes create
substances. These could cause harm to employees, contractors and other people. Sometimes
substances are easily recognised as harmful. Common substances such as paint, bleach or dust from
natural materials may also be harmful.
The health and safety law:
The Health and Safety at Work Act 1974 states employers are responsible for protecting the
safety of their employees at work, by preventing
potential dangers in the workplace. It places general duties on employers to ensure the
health, safety and welfare of all persons while at work. This Act places a legal duty on
employers to ensure, so far as reasonably practicable, the health, safety, and welfare of employees,
and to ensure that employees and others are kept safe. The Health and Safety at Work Act 1974
(HSWA) covers all workplaces and says that an employer must do everything reasonably practicable
to provide a safe and healthy workplace. The HSWA is supplemented by many statutes, regulations,
codes of practice and guidance.
Responsibilities of employer:
All employers, whatever the size of the business, must:
make the workplace safe
prevent risks to health
make sure that plant and machinery is safe to use
make sure safe working practices are set up and followed
make sure that all materials are handled, stored and used safely
provide adequate first aid facilities
tell you about any potential hazards from the work you do - chemicals and other substances
used by the firm - and give you information, instructions, training and supervision as needed
set up emergency plans
make sure that ventilation, temperature, lighting, toilet, washing and rest facilities all meet
health, safety and welfare requirements
check that the right work equipment is provided and is properly used and regularly
maintained
, prevent or control exposure to substances that may damage your health
take precautions against the risks caused by flammable or explosive hazards, electrical
equipment, noise and radiation
avoid potentially dangerous work involving manual handling (and if it can't be avoided, take
precautions to reduce the risk of injury)
provide health supervision as needed
provide protective clothing or equipment free of charge (if risks can't be removed or
adequately controlled by any other means)
make sure that the right warning signs are provided and looked after.
Potential hazards
Labs:
In soap kitchens, labs, and pharmacies, eye contact is a frequent hazard that could endanger their
vision. Employers in school labs are required to utilise powder, such as ammonium sulphate, which
might cause damage to their eyes from dust inhalation. Like tables, which are made in pharmacies,
dust might enter their eyes and injure them. The use of poisonous liquid products by the cosmetic
and pharmaceutical industries also presents a risk of employee skin contact, which could burn or
otherwise harm their skin, as well as employee eye contact, which could harm or blind them if the
product splashes or splatters or if some employees are not wearing the appropriate protective gear.
Additionally, while dealing with bare flames and unanticipated chemical reactions in both
organisations.
Pharmacy:
A special risk that only pertains to pharmacy labs is drug development. Drug development poses a
risk to workers by exposing them to potentially infectious harmful germs. This is particular since
cosmetic corporations do not create pharmaceuticals. Making anticancer drugs exposes people to
substances that are carcinogenic and can cause cancer, which is another risk. This is dangerous and
might be bad for people's health. Only pharmaceutical research labs are allowed to utilise this. The
final danger is drying operations, which might damage your hearing due of the loud noise. Another
specific risk facing pharmacies is the production of dangerous medications, which have the potential
to have devastating health impacts like leukaemia and genetic damage. only authorised places, like
lockers.
