Standardisation is important to reduce variety and
to promote the quality of products by defining
features and characteristics governing their fitness
for purpose. The standards promote clear
unambiguous communication between purchasers
and suppliers for quotation ordering and supply
purposes. In 1994 a single European standard,
EN 29453 (ISO 9453), superseded all other
European national standards, BS 219, DIN 1707,
NFC 90-550. Other equivalent international
standards include QQS 571E, ASTM B32 and
JIS-Z-3382.

Section 3. Hazards Identification

Inhalation of the flux fumes given off at soldering temperatures will irritate the nose and throat. Repeated
or prolonged exposure to flux fumes may cause an allergic reaction leading to occupational asthma.
Solder alloys containing lead give of negligible lead fume at normal soldering temperatures and at
temperatures up to 500ºC. Lead is harmful if absorbed into the body and can cause birth defects and
other reproductive harm.

Section 4. First Aid Measures

Inhalation: Flux fumes emitted during soldering will irritate the nose and throat and may cause an asthmatic type
reaction. Remove affected person to fresh air, obtain medical attention if there is any respiratory
distress.
Skin Contact: Rosin and rosin derivatives can cause a rash to develop. If any skin irritation develops seek medical
advice. Wash hands with soap and warm water after handling solder wire.
Eye Contact: Flux fumes may irritate the eyes. The flux may spit during soldering. Flush immediately with plenty of
water, ensure that the eyeball and the inside of the eyelids are properly bathed by gently prising open the
eyelids.
Ingestion: Not relevant

Section 5. Fire Fighting Measures
Suitable extinguishing media: Dry chemical, carbon dioxide, water spray or foam.
Do not use: Water jet
Exposure hazards: High temperatures above 500ºC may produce heavy metal dust, fumes and/or vapours. The medium will
give rise to irritating fumes.
Protective measures: Fire fighters should wear full protective clothing and breathing apparatus operated in positive pressure
mode.

Section 6. Accidental Release Measures

Personal precautions: Refer to Section 8, Personal Protection.
Environmental precautions: Refer to Section 13, Disposal.
Methods of clearing up: Place in closed container for subsequent disposal.

Section 7. Handling & Storage

Handling: The fumes produced during use should be extracted away from the breathing zone of the operators.
Ensure that the general area is well ventilated. Wash the hands with soap and warm water after handling
soldering products, particularly before eating and drinking or smoking.
These products should be stored in a cool dry area. Keep out of the reach of children and away from
Storage: food and drink.

Section 8. Exposure Controls & Personal Protection

Maximum Exposure Limits (MEL’s):-
Substance: Long Term Exposure Limits (8 Hour TWA) Short Term Exposure Limit (15 min)
Rosin based solder flux fume 0.05 mg/m³ 0.15 mg/m³ Sen
Lead * 0.15 mg/m³ -
Personal Protection:-
Respiratory protection: Necessary if there is a risk of exposure to high concentrations of flux fumes.
Eye Protection: Operators should wear safety goggles to protect the eyes from spitting flux.
Suitable work wear should be worn to protect clothing.
Skin Protection: For blood lead monitoring and medical surveillance requirements, refer to the HSC Approved code of
Practice supporting the Control of Lead at Work Regulations. Employees should be under medical
surveillance if the risk assessment made under the Control of lead at Work regulations indicate they are
likely to be exposed to significant concentrations of lead, or if an employment medical adviser or
appointed doctor certifies that an employee should be under medical surveillance.
A woman employed on work which exposes her to lead should notify her employer as soon as possible if
she becomes pregnant. The employment medical advisor/appointed doctor should be informed of the
pregnancy. Under the Management of Health & Safety at Work (Amendment) Regulations 1994,
employers should assess the risks at work to the health of pregnant workers and workers who have
recently given birth or are breast feeding.

Section 10. Stability & Reactivity

Conditions to avoid: If solder is exposed to temperature over 500ºC lead dust, fume and /or vapours may be produced.
Materials to avoid: Solder will react with concentrated acid to release poisonous fumes of nitric oxide. This will in turn
oxidise to nitrogen dioxide, a red gas with a pungent odour. If personnel are extensively exposed to
these gases then immediate medical attention should be sought, as symptoms can be delayed for a
considerable time period and can be fatal. Solder may react with other strong acids to release highly
flammable / explosive hydrogen gas.

Section 11. Toxicological Information ( toxic effects arising from exposure based on experimental and non
experimental data)
Acute Toxicity: The flux fumes produced during soldering will irritate the nose and throat. For personnel that have
become sensitised to rosin fumes, exposure can cause symptoms of asthma attacks of wheezing),
chest tightness and breathlessness - alveolitis breathlessness and flu like symptoms), or rhinitis and
conjunctivitis (runny or stuffy nose and watery or prickly eyes typical of hay fever). Rosin can also cause
sensitisation by skin contact causing dermatitis.
Lead can cause weakness, vomiting, loss of appetite, convulsions and stupor.
Prolonged and / or repeated exposure to flux fumes may cause some workers to develop an allergic
reaction to them (become sensitised).
Chronic Toxicity: Lead can cause weakness, insomnia, hypertension, headaches and pains in the joints. Chronic
exposure to lead may result in damage to the blood - forming, nervous, urinary and reproductive
systems. Lead is classified as a 2B carcinogen by the IARC (1987). Evidence for carcinogenity is
adequate in animals but inadequate in humans.
Reproductive Toxicity: The placenta offers no barrier to the transport of lead from the mothers blood stream to that of the foetus.
