Hello all,
here is another scientific abstract drawn from Toxline,
I am sure my fellow potters can avoid the kind of exposure
described here (burning eyes and tears, sore throat and coughing).
TITLE: [Acute deterioration of the CO diffusion capacity following =
exposure to ski-wax vapors] AUTHORS: Knopfli B; Guntensperger U; =
Schibler A; Villiger B=20
AUTHOR AFFILIATION: Thurgauisch-Schaffhausische Hohenklinik Davos.=20

ABSTRACT: In cross country skiing use of hot wax is of importance. 90% =
of the active swiss cross country skiers have their own, self maintained =
equipment. Long unprotected exposure to hot wax fumes may cause =
disturbance of lung function. To examine short lasting disturbance in =
pulmonary function, CO-diffusion capacity and dynamic and static lung =
volumes in five healthy human subjects after exposure for one hour to =
hot wax (containing Paraffin and Cera-F) were determined. The subjects =
complained about burning eyes and tears, sore throat and coughing. =
Immediately after exposure all subjects showed a significant decrease of =
the CO-diffusion capacity of 10.6% (SEM 3.9), related to the ventilated =
alveolar space (DCOSB/VA). Maximal decrease of 13.6% (SEM 2.4) was after =
90 min. After 24 hours the reduction persisted with 9.4% (SEM 2.1). The =
dynamic and static lung volumes remained unchanged. In summary a =
reduction of the CO-diffusion capacity after inhalative hot wax exposure =
was observed for at least 24 hours.=20

In response to a request from a representative of the United Auto =

Union, Local 2300, an investigation was undertaken of possible hazardous =
working conditions at the University book binding room and printing shop =
(SIC-2752) at Cornell University. The printing room has three to six =

which=20

conditioning=20
unit. The drip pan associated with this unit had standing stagnant=20
condensate. A thermoplastic adhesive containing petroleum (8002059) wax =

used in the book binding process. Air sampling in the book binder room=20
indicated nondetectable airborne paraffin (8002742) wax or organic =
solvents.=20
Air sampling at the print shop indicated measurable concentrations of=20
hydrocarbon solvents at about one third the permissible level. Based on =
these=20
results it was concluded that a health hazard did not exist from =
employee=20
exposure to paraffin wax fumes or petroleum solvents. Recommendations =
were=20
made to further reduce employee exposures to these agents.

ABSTRACT :
A walk through survey was undertaken at a chrome tannery to gather=20
information for a NIOSH industry wide study of the tanning industry. =
This=20
facility was built in 1955 with an addition in 1973. Currently the =
facility=20
employed 150 individuals in the production area and 40 in the =
administrative=20
area. The products of the factory were finished leather hides with an =
annual=20
production of 500,000 hides. The hides were produced in a variety of =
colors=20
with many different finishes and special treatments. Ventilation =
consisted of=20
a few fans mounted near the ceiling and an open door at the beginning of =
the=20
wet process area. Large amounts of air were drawn out of the building by =
ventilating systems in the spray finishing booths. Workers were =
potentially=20
exposed to calcium-oxide (1305788), hydrogen-sulfide (7783064), ammonia=20
(7664417), sulfuric-acid (7664939), chrome, tannins, paraffin wax fumes, =
resins, leather dust, dye dust, heat and noise. While actual =
measurements=20
were not taken at this site, the practice of good housekeeping rules and =
lack=20
of any strong odors suggest that the working conditions may be good. The =
author suggests improvements for the mixing and storing area of the =
doping=20
department. Drums containing solvents should be sealed more tightly when =
not=20
in use to prevent evaporation of vapors. An in depth industrial hygiene=20
survey at this location is not recommended by the author.
