10. STABILITY AND REACTIVITY
Materials to Avoid
The flux will react vigorously with strong oxidising agents, possible with explosive violence.
11. TOXICOLOGICAL INFORMATION
Acute Toxicity
The flux fumes produced during soldering will irritate the nose and throat. For personnel that have developed an
allergic reaction to modified rosin fumes, further exposure may 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.) Exposure to flux fumes may cause skin irritation
and rash. Modified rosin can also cause sensitisation by skin contact causing redness, irritation, rash or pustules.

Chronic Toxicity
Prolonged or repeated skin contact with modified rosin can lead to an allergic contact dermatitis. The skin will react
by producing anything from weals to pustules. Prolonged or repeated inhalation of modified rosin fumes may lead to
occupational asthma. Cases of occupational asthma due to inhalation of rosin fumes produced from soldering fluxes
are reportable under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 1995.
