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.

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）.
Back to top
Workers exposed to organic solvents for an extended time period incur

increased risk of the following health issues:

Chronic damage to the nervous system, which can result in

concentration and memory impairment, personality changes, and

permanent tiredness.

Reduced sensitivity to touch

Restless arm/leg syndrome

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 approximay 2 m²） or digestive system （total area

approximay 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. Approximay 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

unfortunay, 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: Unfortunay, 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
