The substance is
produced and used in closed system. Personnel protection equipments
(mask, gloves and safety glasses) are used during production, handling
and use of the substance. Occupational exposure to 11-aminoundecanoic
acid may mainly occurs by inhalation of particles.
occupational exposure limits have been determined for 11-aminoundecanoic
acid. To recognize the adverse effects of exposure to non toxic particle
matter, a TLV-TWA of 10 mg/m3 for inhalable particle and
a TLV-TWA of 3 mg/m3 for respirable particles have been establishedby
exposure survey was conducted in the Atofina's production plant
of Marseille-Saint Menet in 1994 and 1995.
In 1994, inhalable
particulates were monitored one time at 2 working places
and in the ambient air:
were applied to reduce the exposure of the operator in
charge of the packaging. New big bags were used for the packaging instead
of recycled big bags, which were at the origin of the release of a
large amount of inhalable particles.
According to this
corrective measure, the 8-hour TWA at the packaging working
areas was reduced to 0.90 mg/m3 (mean of 2 measurements), in a new
measurement campain performed in 1995. Inhalable particles were assumed
to be reduced in the same proportion for the driver of fork-lift trucks
and in the ambient air close to the bag filling machine. This assumption
was confirmed in subsequent occupational exposure surveys (Personal
monitoring) performed in 2000, 2001, 2002 and 2003. All measurements
were well below the TLV-TWA of 10 mg/m3 forinhalable particle
and the TLV-TWA of 3 mg/m3 for respirable particles
