In order to determine what level of PPE (Personal Protective Equipment) should be worn when working on, or observing, Energized Electrical Equipment, what type of study would need to be completed in order to provide labels for the equipment that would contain hazard boundaries, PPE required, and level of incident energy?
Employers have duties concerning the provision and use of personal protective equipment (PPE) at work.
PPE is equipment that will protect the user against health or safety risks at work. It can include items such as safety helmets, gloves, eye protection, high-visibility clothing, safety footwear and safety harnesses. It also includes respiratory protective equipment (RPE).
Why is PPE important?
Making the workplace safe includes providing instructions, procedures, training and supervision to encourage people to work safely and responsibly.
Even where engineering controls and safe systems of work have been applied, some hazards might remain. These include injuries to:
the lungs, eg from breathing in contaminated air
the head and feet, eg from falling materials
the eyes, eg from flying particles or splashes of corrosive
liquids
the skin, eg from contact with corrosive materials
the body, eg from extremes of heat or cold
PPE is needed in these cases to reduce the risk.
What do I have to do?
Only use PPE as a last resort
If PPE is still needed after implementing other controls (and there
will be circumstances when it is, eg head protection on most
construction sites), you must provide this for your employees free
of charge
You must choose the equipment carefully (see selection details
below) and ensure employees are trained to use it properly, and
know how to detect and report any faults
Selection and use
You should ask yourself the following questions:
Who is exposed and to what?
How long are they exposed for?
How much are they exposed to?
When selecting and using PPE:
Choose products which are CE marked in accordance with the
Personal Protective Equipment Regulations 2002 – suppliers can
advise you
Choose equipment that suits the user – consider the size, fit and
weight of the PPE. If the users help choose it, they will be more
likely to use it
If more than one item of PPE is worn at the same time, make sure
they can be used together, eg wearing safety glasses may disturb
the seal of a respirator, causing air leaks
Instruct and train people how to use it, eg train people to remove
gloves without contaminating their skin. Tell them why it is
needed, when to use it and what its limitations are
Other advice on PPE
Never allow exemptions from wearing PPE for those jobs that
‘only take a few minutes'
Check with your supplier on what PPE is appropriate – explain the
job to them
If in doubt, seek further advice from a specialist adviser
Maintenance
PPE must be properly looked after and stored when not in use, eg in a dry, clean cupboard. If it is reusable it must be cleaned and kept in good condition.
Think about:
using the right replacement parts which match the original, eg
respirator filters
keeping replacement PPE available
who is responsible for maintenance and how it is to be done
having a supply of appropriate disposable suits which are useful
for dirty jobs where laundry costs are high, eg for visitors who
need protective clothing
Employees must make proper use of PPE and report its loss or destruction or any fault in it.
Monitor and review
Check regularly that PPE is used. If it isn’t, find out why
not
Safety signs can be a useful reminder that PPE should be worn
Take note of any changes in equipment, materials and methods – you
may need to update what you provide
Types of PPE you can use
Eyes
Hazards
Chemical or metal splash, dust, projectiles, gas and vapour,
radiation
Options
Safety spectacles, goggles, face screens, faceshields, visors
Note
Make sure the eye protection chosen has the right combination of
impact/dust/splash/molten metal eye protection for the task and
fits the user properly
Head and neck
Hazards
Impact from falling or flying objects, risk of head bumping, hair
getting tangled in machinery, chemical drips or splash, climate or
temperature
Options
Industrial safety helmets, bump caps, hairnets and firefighters'
helmets
Note
Some safety helmets incorporate or can be fitted with
specially-designed eye or hearing protection
Don't forget neck protection, eg scarves for use during
welding
Replace head protection if it is damaged
Ears
Hazards
Noise – a combination of sound level and duration of exposure, very
high-level sounds are a hazard even with short duration
Options
Earplugs, earmuffs, semi-insert/canal caps
Note
Provide the right hearing protectors for the type of work, and
make sure workers know how to fit them
Choose protectors that reduce noise to an acceptable level, while
allowing for safety and communication
Hands and arms
Hazards
Abrasion, temperature extremes, cuts and punctures, impact,
chemicals, electric shock, radiation, vibration, biological agents
and prolonged immersion in water
Options
Gloves, gloves with a cuff, gauntlets and sleeving that covers part
or all of the arm
Note
Avoid gloves when operating machines such as bench drills where
the gloves might get caught
Some materials are quickly penetrated by chemicals – take care in
selection, see HSE’s skin at work website
Barrier creams are unreliable and are no substitute for proper
PPE
Wearing gloves for long periods can make the skin hot and sweaty,
leading to skin problems. Using separate cotton inner gloves can
help prevent this
Feet and legs
Hazards
Wet, hot and cold conditions, electrostatic build-up, slipping,
cuts and punctures, falling objects, heavy loads, metal and
chemical splash, vehicles
Options
Safety boots and shoes with protective toecaps and
penetration-resistant, mid-sole wellington boots and specific
footwear, eg foundry boots and chainsaw boots
Note
Footwear can have a variety of sole patterns and materials to
help prevent slips in different conditions, including oil - or
chemical-resistant soles. It can also be anti-static, electrically
conductive or thermally insulating
Appropriate footwear should be selected for the risks
identified
Lungs
Hazards
Oxygen-deficient atmospheres, dusts, gases and vapours
Options – respiratory protective equipment (RPE)
Some respirators rely on filtering contaminants from workplace
air. These include simple filtering facepieces and respirators and
power-assisted respirators
Make sure it fits properly, eg for tight-fitting respirators
(filtering facepieces, half and full masks)
There are also types of breathing apparatus which give an
independent supply of breathable air, eg fresh-air hose, compressed
airline and self-contained breathing apparatus
Note
The right type of respirator filter must be used as each is
effective for only a limited range of substances
Filters have only a limited life. Where there is a shortage of
oxygen or any danger of losing consciousness due to exposure to
high levels of harmful fumes, only use breathing apparatus – never
use a filtering cartridge
You will need to use breathing apparatus in a confined space or if
there is a chance of an oxygen deficiency in the work area
If you are using respiratory protective equipment, look at HSE’s
publication Respiratory protective equipment at work: A practical
guide
Whole body
Hazards
Heat, chemical or metal splash, spray from pressure leaks or spray
guns, contaminated dust, impact or penetration, excessive wear or
entanglement of own clothing
Options
Conventional or disposable overalls, boiler suits, aprons, chemical
suits
Note
The choice of materials includes flame-retardant, anti-static,
chain mail, chemically impermeable, and high-visibility
Don't forget other protection, like safety harnesses or life
jackets
Emergency equipment
Careful selection, maintenance and regular and realistic operator training is needed for equipment for use in emergencies, like compressed-air escape breathing apparatus, respirators and safety ropes or harnesses.
