Health and Safety
Designers have a duty of care.
They have a responsibility to ensure
the products we use are safe. This
only applies if the product is being
used for the purpose for which it was
intended, by the users for whom it
was intended and in the environment
it was intended for.

Personal Safety
is about making sure people are not
exposed to unnecessary risk and harm
• Using personal protection equipment – eye protection, face masks,
safety shoes, overalls
• Check tools and equipment are safe to use – that everything is in
good working order
• Maintain a safe environment – nothing on floor to trip over,
extraction systems working properly
• Accident procedures clearly understood
• 1) make scene of accident safe
• 2) assess the injury
• 3) treat the injury
• 4) write an accident report
• 5) undertake work to prevent accident happening again.

Risk assessment
• 1) identify the specific risk e.g. for using an
iron the risk is burning your hand or arm with
the iron or getting a burn from steam, also risk
of dropping iron on your foot.
• 2) assess the probability or chances of an
accident happening
• 3) minimise risk: is there anything you can do
to reduce the likelihood of an accident taking
place.
• After considering these three aspects, the risk
becomes acceptable or not acceptable.

COSHH
• The law requires employers to control exposure
to hazardous substances. Employers have to
comply with the Control of Substances Hazardous
to Health Regulations 2002 (COSHH)
• FUMES, DUST, BACTERIA, ADHESIVES, PAINTS can
lead to skin irritation, dermatitis, asthma, losing
consciousness, cancer, infection
• E.g. – solvent based spray glues, tensol cement,
etching agents for PCBs, soldering and dusts
produced from cutting and finishing materials

Quality
• Quality of design is not about manufacture. It
could be the look or the novel concept – user
perception plays a part.
• Quality of design is indicated by
• how well product functions,
• how aesthetically pleasing it is and
• how appealing it is to the user.
• It must also be sustainable – standing the test of
time, not having a negative impact on the
environment.

Quality of manufacture
• How well a product has been made
• How appropriate materials are – consider cost,
availability, working properties and environmental
issues
• How appropriate manufacture methods are
• How good the surface finish is
• How well components fit into product
• Quality depends on Design Tolerance allowable.
e.g. 100mm ±2mm for a distance or a resistor of 2k
with a tolerance of ± 5% (gold band)

Quality Control
Quality control is about ensuring that
products conform to standards that will
ensure they are safe to use.
Quality control checks are required. You must
identify key quality control points in the
manufacturing process.
Quality marks and symbols show they meet
agreed standards e.g. ISO9000 – quality
management system to ensure continual
improvement.

Quality marks: BS kitemark and CE mark
A kitemark means the British Standards Institute (BSI) has
independently tested a product, confirmed that it conforms to
the relevant British Standard, and has issued licence to the
company to the company to use the kitemark. Safety and
reliability in such things as fridges, plugs, helmets are shown
by these marks
The CE marking (also known as CE mark) is a
mandatoryconformity mark on many products
placed on the single market in the European
Economic Area (EEA). The CE marking certifies that
a product has met EU consumer safety, health or
environmental requirements. CE stands for
Conformité Européenne, "European conformity" in
French.
