aging than low tones at the same sound level. Impact noise can
also be hazardous, for example, hammer blows.
Risks
Damage to hearing can occur at noise levels higher than the limits.
In severe cases, the damage to hearing can become permanent.
Precautions
•
Use hearing protection. Make sure that it has been tested and
that it protects against the corresponding noise level.
Solvents
Fluids that dissolve grease, paint, lacquer, wax, oil, adhesive, rub‐
ber, and so on, are called organic solvents.
Such liquids include white (petroleum) spirits, petrol, alcohols, die‐
sel, xylene, trichloroethylene, and toluene.
Many solvents are flammable and constitute a fire hazard.
Risks
Products that contain solvents produce fumes that can cause dizzi‐
ness, headaches, and nausea. They may also irritate mucous mem‐
branes in the throat and the respiratory tract.
If solvents come in direct contact with the skin, this may cause dry‐
ing and cracking. The risk of skin allergies increases. Solvents may
also cause injury if they penetrate through the skin and are absor‐
bed by the blood.
If the body is continuously exposed to solvents, the nervous system
may be damaged. Symptoms include sleep disorders, depression,
nervousness, memory disorder, or general tiredness and fatigue.
Continuous inhalation of petrol and diesel fumes is suspected to
cause cancer.
Precautions
•
Avoid inhaling solvent fumes and make sure the ventilation is
adequate. If necessary, wear a fresh-air mask or respiratory
device with a suitable filter for toxic gases.
•
Never leave a solvent container open; seal the lid carefully.
•
Use solvents with a low content of aromatic substances. This
reduces the risk of injuries.
•
Avoid skin contact.
•
Use protective gloves.
•
Make sure that work clothes are solvent-resistant.
Fire and explosion risks
Examples of explosive substances are oils, petrol, diesel fuel,
organic solvents (such as lacquer, plastic, and cleaning agents),
rust proofing agents, welding gas, gas for heating (acetylene), and
high concentrations of dust particles from combustible materials.
Machine and vehicle tyres are highly flammable and cause fires that
spread explosively.
Risks
Examples of the causes of ignition include welding, cutting, smok‐
ing, sparks produced by grinding, and flammable materials coming
into contact with hot machine parts.
