This illustration distinctly shows the importance of using a fume extraction system, even when soldering only once in a while or for just a few hours a day. The captured particles are primarily condensed residues from flux. Without a filter system these particles ill be partly inhaled the operator with the remainder spread over the work object and workplace. In contrast, a proper filter system will eliminate not only the particles, but will also catch and eliminate dangerous gases created in the soldering process.

Tel:18607695075谢生
用风机将烟雾抽入机箱，通过内置的滤芯进行过滤，主要能够起到过滤粉尘
、异味、有毒气体和杀灭部分细菌的作用。滤网又分：集尘滤芯、玻纤滤芯、
HEPA滤芯、活性炭滤芯等。其中最关键就是活性炭滤芯，它能起到分解有毒气体
和杀菌作用，特别是抑制二次污染。产品的特点是风机功能以及滤芯的质量决定
净化效果，机器的放置以及室内布局影响净化是否完全，室内净化效果是否均衡
。滤芯需定期更换。
烟雾组成成分及危害:
通常在焊接烟雾中有95％是焊料及助焊剂在高温下挥发出的微粒，这些微粒
飘浮在空气中在一定的光线照射下人眼可以观察到，即我们能够看到的烟雾。而
另外有5％是以气体方式散发在空气中，我们的肉眼是看不到的，而这些气体中
含有大量的一氧化碳、二氧化碳、甲醇、乙醇、甲烷、甲醛等有害性成分。
操作者长时间在以上环境下工作，吸入过量有毒物质，将会引起头痛、恶心、哮
喘、慢性支气管炎等症状，严重影响身体健康，同时也影响正常生产。
Hazardous smoke and fumes, harmful to your health if inhaled, are
present in many workplace environments. Operations using lead-free
solder, lasers, solvents, and glues are especially at risk.
Overexposure can lead to serious – and possibly long term – medical
problems.Health difficulties such as nosebleed, eye irritation, and
sore throat are occurring with increasing frequency in the workplace,
as are incidences of dermatitis, occupational asthma, and, in some
cases, permanent lung damage.

OCCUPATIONAL ASTHMA
“Occupational Asthma is a disease characterized by variable air flow
limitation and/or airway hyper-responsiveness due to causes and
conditions attributable to a particular occupational environment and
not to stimuli encountered outside the workplace.” (Bernstein et al
1993)
Fumes and gases in industrial areas are often dangerous to the people
working in those areas. Some of these substances are readily visible
or have a distinct odor; others are invisible and odorless. Many are
toxic and can lead to allergic reactions, sometimes progressing to occupational asthma.
Occupational asthma is a major issue in electronics manufacturing
because when a worker develops occupational asthma, they must be
removed from the working area, sometimes permanently. In some
countries, cases of occupational asthma due to flux fumes and/or
isocyanates have already lead to legal claims against employers.
Occupational asthma is often indicated by symptoms common to hay
fever – an itchy, blocked, or runny nose, often accompanied by
sneezing and glazed, itchy, or watering eyes.
LEAD-FREE SOLDER
The transition to lead-free soldering has reduced strain on the
environment, but for the operator, the hand soldering process has
become more dangerous. The lead in the solder is gone, but to get the
solder wire to flow properly, substantially more flux must be used.
The temperature needed to create a good solder joint using lead-free
solder is also higher, causing a stronger reaction within the flux and
creating more solder smoke with a greater number of particles. Lead-
free soldering produces up to 250 % more particles between 0.5 and 1.0
microns in diameter, the size that is the most dangerous to inhale. In
addition to particles, solder smoke can contain isocyanates,
aldehydes, and other unhealthy substances.
Lead-free soldering causes up to 250 % more particles in the breathing
zone … roughly 20 million particles between 0.3 and 1.0 microns in
diameter per cubic foot, or about 700 million particles per cubic
meter.

PARTICLES
Respirable particles – Many particulate LGACs are very small
(generally less than 1 micron in diameter), so they can be easily
inhaled.
Toxic particles – Some particulate LGACs may cause allergic,
carcinogenic or toxic effects, such as the chrome and nickel
particles produced when working with lasers on stainless steel.

GASES
Volatile Organic Compounds (VOCs) are often produced when working with
lasers on plastics.
Many VOCs already have Workplace Exposure Limits in place according to
COSHH (control of substances hazardous to health).

Skin dryness and irritation; non-allergic eczema
SOLVENT OVERVIEW, TYPES, AND FAQs
Overview
Few workers understand the risks of exposure to solvents, yet many are
exposed to them on a daily basis. Everyone working in an industrial
environment comes into contact with chemicals that contain solvents.
How dangerous the chemicals containing the solvents are depends on the
properties of the substances and the precautions taken when handling
them.
Organic solvents are absorbed primarily through the mucous membranes
(total area: 80-200 m²), but some can also be absorbed through the
skin (total area approximately 2 m²) or digestive system (total area
approximately 10 m²).
There is a noticeable trend of people becoming more sensitive to
allergic materials, such as airborne particles and solvents, in
industrialized societies. This indicates a need for improved
extraction equipment and precautions.
Types
Isocyanates Isocyanates is the name of a large family of substances
such as TDI (toluene-2,4-diisocyanate), MDI (diphenyl-methane
diisocyanate), and HDI (hexa-methylene diisocyanate) used extensively
in industrial workplaces. There are a large number of different
isocyanates with different characteristics, but common to all of them
is that they cause health problems, especially when inhaled. One of
the largest areas of use for isocyanates is in the manufacture of
polyurethane plastics (PUR). PUR appears as a soft compact foam and is
found in coatings and other chemical products. Approximately 5 % of
all plastics used are currently PUR and its usage is increasing.
However, during the polymerizing and heating of PUR, a number of
isocyanate combinations are formed. When heating phenyl formaldehyde
resin, methyl isocyanates are formed.
Isocyanates can easily be absorbed through the skin and through the
mucous membranes. In contact with water they form amines that will
stay in the blood for a long time. Isocyanates are also found in
polyurethane materials (coatings), glues, and varnishes.
Isocyanates cause health hazards – especially when inhaled in the
form of gas, steam, dust, or aerosol droplets. Inhalation can cause
irritation in eyes, mucous membranes, and respiratory system with
symptoms resembling asthma or bronchitis and decreased lung function.
The risk of hypersensitivity is high.
Isocyanates can also cause skin irritation. Repeated contact can cause
eczema, and in some cases, skin allergy. Isocyanates have a very low
limit value … so low that you may be exposed to dangerous
concentrations without noticing, as isocyanates are invisible and
odorless at low levels. An allergic person can develop problems even
when exposed to concentrations below the hygienic limit value.
Recently, new health hazards have been discovered with certain PUR
coatings and some PUR glues used in the manufacture and repair of
printed circuit boards. The same risks occur when working with coated
optical cables that contain small amounts of PUR and coated wire. When
these materials are heated, isocyanates are formed in such high
concentrates that it can cause asthma. It is believed that the thermal
segregation starts at 150-200°C. There are also strong reasons to
suspect that isocyanates can be formed when heating resin products
like fluxing materials.
Alcohols Inhalation or skin contact with alcohols such as methanol,
ethanol, or isopropanol can cause dizziness, headache, disturbed
vision, or fainting. Absorption over a longer period can permanently
damage the eyesight of the victim.
Aldehydes Aldehyde solvents such as formaldehyde and acetaldehyde are
transformed when heat is applied to them, resulting in fumes that have
an irritating effect on the eyes and respiratory organs. Inhalation
can induce headache, dizziness, and fainting in severe cases.
Esters (acetates) Esters such as ethyl acetate and dioctyl phthalate
are often used as solvents and dissolvents in the manufacture of
paints, plastics, and synthetic fibers. Like most solvents, they cause
irritation of the respiratory passages, but long term exposure causes
kidney and liver damage.
There are many other solvents in common use, including ketones,
mercaptans, organic acids, and ethers, all of which have an effect on
the human body, primarily on the respiratory system. Skin contact
(splashes) resulting in eczema is a secondary, but fairly common
occurrence.
FAQs
Why are solvents dangerous?
Can the body break down solvents?
Are all solvents equally dangerous?
What parts of the body do solvents harm?
Is the damage done by solvents permanent?
Q:Why are solvents dangerous?
A: Solvents dissolve fat. The easier they dissolve fat, the easier
they are absorbed by the body and the greater their capacity for doing
damage. The ability to dissolve fat is partly the reason why solvents
are used, and is one of the main reasons why they are so dangerous if
they get into your body.
The cells of the brain contain a high degree of fat. Since the brain
works like a sponge in absorbing solvents, this puts the nervous
system at great risk.
Q:Can the body break down solvents?
A:Yes, the liver can break down many of the solvents. But
unfortunately, the chemicals formed when these substances are broken
down can be even more dangerous than the original solvents.
It can take a long time for your body to break down solvents – so
long, in fact, that the body cannot get rid of everything during the
night or even over the weekend. This is very serious because it means
that solvents can accumulate in your body, sometimes causing
irreversible damage.
Q:Are all solvents equally dangerous?
A: No, some are safer than others. Also, the body absorbs some more
slowly than others. If you have a choice of solvents, use one that
causes as little harm as possible and is absorbed very slowly.
Q:What parts of the body do solvents harm?
A:That depends on the solvent in question. The brain, bone marrow,
liver, and kidneys are susceptible to damage, but the most common
effect is damage to the nervous system. Just as with alcohol (which is
a solvent) as the body absorbs more and more of a solvent, reactions
become slower and judgment is impaired. In many jobs, those events can
open the victim to other, even more extreme dangers.
Q: Is the damage done by solvents permanent?
A: Unfortunately, in many cases the damage is irreversible. It has
been proven that occupational symptoms appear slowly over a long
period. By the time a condition is diagnosed, lasting damage may have
been caused to the nervous system, respiratory system, eyes, brain,
liver, and kidneys.
GLUES
The main health risks of long-term exposure to glues are:
- Skin irritation
- Skin drying
- Allergic contact eczema
- Asthmatic problems from inhalation of glue dusts and solvents
The level of health risk varies depending on the type of glue being
used, with non-hardening glues (“hot glues” that gain strength by
cooling) being least dangerous. Glues that strengthen by drying are
somewhat more harmful, with water?based glues being less dangerous
than solvent?based types. Glues that pose the highest risk of health
concerns are “hardening” glues that cure independent of surrounding
conditions.
HARDENING GLUES – HEALTH CONCERNS
Polyurethane glues – Polyurethane glues contain isocyanates that are
released during application. Isocyanates can cause:
Asthma
Hyper-sensitivity to isocyanates
Breathing problems when exposed to other fumes (perfumes, motor
vehicle exhaust, tobacco smoke, etc.)
Irritation of skin and eyes
Reduced lung capacity
Acrylate glues – Acrylate glues contain high concentrations of
acrylate, methacrylate or cyanoacrylate esters that can cause contact
allergies.
Epoxy glues – Epoxies can cause:
Skin irritation
Allergic contact eczema
Silicone glues – Residue products of silicone glues include oximes,
alcohols (alcoxy “methanol”, methoxy), and acetone. These volatile
by-products can cause
