People of flesh and blood are vulnerable. Especially our senses, which we constantly need to make contact with others and the environment possible.
Some protection is well established as an umbrella or a motorcycle helmet.
There are many more. Make, depending on the job you are going to do, your own risk analysis. Knowing danger and avoiding injury is better than regret afterwards.

As a work or sport is risky, it is recommended not to do this alone. Do it with two or more, so there is always someone to watch, who can help or can get help. Even if you're careful, you can have an accident. Material defects, ignorance of yourself or others, crowds, distractions... you cannot exclude any unforeseen circumstances.

Protection against noise
Chainsaw and other power tools are not only due to their cut quality and speed dangerous.
140 dB causes irreversible damage to the hearing, and
150 dB can cause deafness, all higher than
192 dB can lead to death.

Maximum exposure duration at various levels without the risk of hearing damage.

Earmuffs or earplugs are not expensive. Hearing damage is irreversible, and never recovers.

Protection against light
Too much and too bright light can damage your eyes. The use of a welding screen or glasses is evident. Also, sunglasses or goggles help against glare or snow blindness.
(Use shadow, a hat and sunscreen in the sun.)

Darkness is also a problem: make sure your work place and –spot is well lit.
Make sure you are seen (fluorescent vest, (flashing) light).

Sun protection
Avoid sunburn. Wear a hat and protective clothing. Don’t stay too long (20 min.) in the sun.
You can use coconut oil as a sunscreen. Or mix olive oil, lemon juice (or lime) (and beer).
Are you still burned by the sun, you can cool the skin with yogurt, cucumber and grated potato as aftersun.

In the winter you burn on snow just as quickly as on the beach in the summer, especially through the reflection of UV light (right up to your nostrils)! The skin turns red due to an influx of blood into the small subcutaneous blood vessels, so that your skin also feels warm (glows).

Protection against dust (mist and smoke)
Fibers of glass wool can irritate immensely. Cover each piece of skin.
Also, use a dust mask when working with fast rotating grinding mill, grinding or grinding stone, sanding, fine powders (cement), and demolition.
Bangkok motorcyclists use for years already a masks in traffic.
With sprays verify which filters are prescribed.

Protection against injuries
A helmet protects somewhat against falling objects. Or a bike helmet also when you fall.
Safety goggles protect your eyes from sparks, splinters when cutting, milling, drilling and grinding.
A facial mask is useful when using chain saw and brush cutter. (Or fencing sport.)
As a beekeeper you can use a hat with a veil.
(Waterproof) steel-toed shoes and sturdy soles are quite established.
Knee pads are useful when kneeling: weeding, flooring, roofing.
Gloves are available for various applications: dishwashing gloves to work long in water, woven metal gloves to bone, leather ones for rough jobs, thin surgical gloves for hygienic (or dirty) work, rubber for chemical products....

Fall protection
Keep the work area orderly and well lit.
A ladder is usual not to work, but to bridge height.
Make sure she is stable: adequate and not too sloping, flat, non-slip on smooth floors, or pins under wide feet on soft ground, or with lateral stabilizers. Make the ladder if possible fixed.
If necessary, also yourself.
Work at height: fit a railing or banister. Protect yourself with a harness or rope. Provide nets to catch falling objects.
Observe the maximum load that a ladder or platform can bear.
Use appropriate props.

Protection against cold and hypothermia
If you 're numb, you can’t do much more. So. Prevent it. Hypothermia can be deadly. When surfing and diving we use a neoprene suit. On the motor bike warm clothing underneath a leather suit. Double gloves and socks and a cap on the bike.

Protection against wet
Wet in itself is not really so bad. But you quickly cool off. Rain gear is still highly recommended. Or waders to work in ditches and ponds.

Protection against heat
In forging and welding, use leather gloves and apron against sparks and hot metal. And tongs. Oven mitts in the kitchen. Do you work with an open flame, keep a working fire extinguisher and a fire extinguisher (cloth) within reach.

Protection against beating
In martial arts is sometimes used a toque to protect the testicles. Boxing gloves, fist protectors and soft helmets protect attacker and defender.
Shin guards can be found at the football equipment. Rugby also has a whole arsenal.

The whole of these materials is called PPE: Personal protective equipment models.

Working is unhealthy because 100% of the work accidents take place during work.
