INFLAMMABILITY AND EXPLOSION DANGER |
|
- Not inflammable without primer
- With primer it is inflammable at temperature
over 400°C
- It is immediately auto-extinguishing
- It is not explosive
|
TOXICOLIGICAL DATA |
|
| In the case of total destruction by fire (by
persistent flame at 700°C) before auto-extinguishing, the
product will exhale C0, C02, H20 as steam and will leave carbon
residue. HAZARDOUS FUMES or DUST may be generated when soldering,
welding, burning, wire brushing, melting or processing enameled
wires. Excessive exposure to dust may cause irritation to the
eyes, skin and/or respiratory systems. The wearing of appropriate
protective eye, skin and breathing equipment may be required.
Inhalation of fumes should be avoided. The soldering of polyurethane
enamel can present an Isocyanate inhalation hazard. Levels of
free Isocyanate above the control limit can be generated during
the soldering operation. It is recognised that exposure to Isocyanates
can lead to sensitisation and occupational Asthma. Fumes should
be removed by efficient exhaust ventilation. |

EXPOSURE LIMITS |
|
| Exposure limit 0.020mg per cubic metre for an
8 hour time weighted average reference period. Short term exposure
limit 0.07mg per cubic metre for a 10 minute period. |
| |
ECOLOGICAL DATA |
|
Waste should normally be recycled due to the
high value of the base metal.
It should be noted that enameled wires
are lubricated with wax at < 75mg per square metre of wire
surface. |
