FRENCH CANADIAN LABELING LAWS

A group of law students from the University of Montreal have taken upon
themselves to have the law on food and agricultural products enforced in the
retail stores. Article 38, Section III of Regulation 683 of the Province of
Quebec, stipulates that: "The use of French is obligatory in all inscriptions,
and inscriptions in another language must not take precedence over those in
French". This group of students has so far filed 14 suits against Steinberg
Stores and 10 against Dominion Stores for labels on products that do not meet with
the law requirements. Steinbergs, for one, and according to La Presse, May 31,
1972, have written to their suppliers requesting that they replace all items on
their shelves that do not meet the requirements mentioned above, or take them
out of the stores completely. The Food Brokers Association, the Sea Food Distri-
butors Association, the Montreal Chamber of Commerce, the Association of Canadian
Food Manufacturers and a few others are to meet with Mr. Toupin, the Minister of
Agriculture, soon and discuss the implications of such action by the students.

SAFETY: LIFT TRUCKS

The increasing use of lift trucks implies a potential hazard whenever they
are used in reasonably confined spaces such as storage rooms, the new continuous-
type degreening rooms, and any areas with less than extreme ventilation. Any such
internal combustion-type equipment can build up hazardous levels of carbon monoxide.
We have already had one near fatality in a Florida citrus packinghouse.
Electric-type lift trucks are definitely preferable in terms of such atmospheric
pollution hazards. Although their initial investment cost is high, their cost-per-
unit-handled is less over a span of years (e.g. 10-15 years).
If internal combustion-type trucks are used, they should use butane (or "L.P."
gas), never gasoline, and should be equipped with a catalytic muffler. Such muff-
lers should be regularly serviced and/or replaced according to the manufacturers'
directions.
NOTE: This is yet another reason for scrupulously following our standard
recommendation that all degreening rooms should have ventilation equal to one air
change per hour based on the volume of the empty room.

HUMIDITY IN STORAGES AND DEGREENING ROOMS


This is a psychrometric chart showing the relationships between temperature,
relative humidity, and actual water content of the air at a given temperature and
relative humidity.

To many it will, perhaps, seem just another unnecessary complication in a
life that is already too complicated. However, we find an increasing number of
shippers who are familiar with such charts; and to others it can afford a most
valuable medium for discussing heating, humidity, and refrigeration equipment
with suppliers.

On this chart, we have indicated five optimum conditions for storage on
degreening of various varieties. All call for 95% relative humidity. However,
as a wise old statistician once remarked, "Percent is the fertile mother of fallacy"
The scale on the right-hand margin gives the absolute humidity or the actual amount
of water in grains of moisture per pound of air necessary to provide the relative
humidity indicated. A quick glance will show that six times as much moisture must
be vaporized at 850F ("E") to give 95% R.H. as at 330F ("A"). Obviously, this
greatly affects selection of humidity maintenance equipment in a dual purpose
(degreening and refrigeration) room.
