Q: What is the Coalition of Northeastern Governor's
(CONEG)?
A: Numerous states have passed hazardous
packaging regulations that will impact both the screen printing and supply
industries. This legislation, modeled after the Council of State Governments
(CSG) toxics reduction legislation, sets limits on the amount of lead, mercury,
cadmium and hexavalent chromium that can be found in any package or packaging
components. Packaging components have been defined as any individual assembled
part of a package, including inks and labels. The CSG has taken over this
legislation originated by CONEG (Coalition of Northeastern Governors). For
more information, visit their website at: www.csg.org Essentially, the law
states that no product shall be offered for sale or for promotional purposes
in a package that contains levels of the aforementioned heavy metals in excess
of 100 parts per million (0.01%), effective January 1, 1994.
Q: What Nazdar products currently comply with CONEG
regulations?
A: Based on information obtained from random
test data, Nazdar certifies that the standard colors in the ink lines listed
below comply with current CSG regulations regarding content of lead, mercury,
cadmium and hexavalent chromium.

Q: What FDA Compliance issues are there in Screen
Printing inks?
A: Often screen printers have questions
concerning Food and Drug Administration (FDA) compliance of the ink they are
using to print on food or food packaging. Commonly, the end user of the finished
product will require a statement of FDA compliance from the printer. In turn,
the printers are requesting FDA compliance from the ink manufacturers.
Q: How can you tell if a screen ink is suitable
for use on food products and packaging?
A: Several items must be looked at before
one can determine if a screen printing ink is suitable for use on food products
or food packaging.
First, is the ink going to be in direct or indirect contact with the food
product? A processing or packaging component (ink), which is intended to be
in immediate contact with the food is a direct contact material. An example
is the inside surface of a bread bag which does come into contact with the
loaf of bread. Indirect contact is only occasional or minimal contact with
a food product. The outside surface of a bread bag is a good example of indirect
contact. If a material will be in direct contact with food, it must be composed
only of direct or indirect food additives as found in 21 CFR 170-189. Please
note that none of Nazdar's inks are composed of direct or indirect food additives
and are therefore not suited for direct food contact use.
The second item in determining whether or not screen printing ink can be used
in food applications is the presence of a food-contact-approved functional
barrier. The FDA states that if there is a food-contact-approved functional
barrier (e.g., resinous coating, protective film, transparent cover, etc.)
separating printed material from the food, then such use of printing ink is
not a food-additive situation. The functional barrier must be of sufficient
thickness and continuity that it prevents the ink from passing through the
coating and migrating to the food. The manufacturer of the barrier must employ
good manufacturing practices to ensure that the barrier has formed a continuous
coating so that no pin holing is present and the barrier is of sufficient
thickness to prevent ink migration.
Q: What are the restrictions with functional barriers
and food packaging printing?
A: In a situation where a printer has an
approved functional barrier between the surface to be printed and the food
product, conventional water and solvent-based inks may be used for printing.
To determine whether or not a functional barrier is of the quality needed
to prevent ink migration, the FDA should be consulted. In addition to discussing
functional barriers, the ink chemistry, application and end product use should
be discussed and reviewed by the FDA prior to printing.
Q: What are the restrictions with UV inks on food
packaging?
A: Ultra-Violet (UV) curable screen inks
have different properties than water and solvent-based inks. Because 100 percent
polymerization or cure cannot be achieved or guaranteed in the UV process,
there is the possibility that untreated residual monomers, oligomers and photo
initiators remain in and on the surface of the printed ink film and may migrate
to the food product. Currently neither UV inks nor UV raw materials are approved
for direct or indirect food contact and are not recommended for use on food
packaging even when separated by a functional barrier. Recently the FDA has
delivered a ban on the use of lead and cadmium based decorations on the top
20mm of glass drinkware distributed in the US. The ban is intended to protect
children.

Q: What are the unique characteristics of UV Inks?
A: UV inks cures only by exposure to ultraviolet
light - not evaporation and are 100% solid (solvent and water-based inks
are approximately 50% solid and 50% solvent or water).
Q: What are the hazards associated with UV Ink skin
contact?
A: UV inks contain acrylates which may cause:
- irritation
- redness
- burns
- blistering (contact with the skin)*
*Repeated skin contact may cause sensitization. Sensitized individuals
may develop the previous symptoms even if exposed to small quantities of ink.
Q: What precautions should be taken when using UV
Ink?
A: Wear impervious gloves and protective
glasses. Wear impervious aprons and shoes (Press operators).
Q: What should I do if I come into contact with
a UV curable product?
A:
- Immediately flush eyes with large amounts of cool water (15 minutes) and
seek medical attention. A MSDS of the product should be taken to the doctor.
- Immediately wash skin with large amounts of water. Use soap and water or
other skin cleaning compounds to remove ink.
- Never try to remove UV ink from the skin by using solvent or thinners.
Such action is likely to increase the possibility of undesirable effects.
- The presence or consumption of food, beverages or smoking materials should
be banned from the work environment. Operators should wash their hands thoroughly
prior to eating, drinking or smoking to eliminate accidental ingestion of
UV curable materials.
- All garments and protective clothing, soiled with even small amounts of
UV materials, should be discarded or laundered in hot water and detergent,
separately from other garments.
- Housekeeping should emphasize the necessity of cleaning up spills, cleaning
utensils such as measuring equipment, knives and stirrers. Because UV ink
will not dry unless exposed to intense UV light, it is easily spread from
one area to another without anyone realizing it.
The most important item in UV safety is proper training in the correct use
and housekeeping of ultraviolet curable inks. If the above steps are followed,
UV ink will provide excellent results with minimal health and safety problems.

Q: What are the standards for lead and other heavy
metals in paints and elemental lead in children's toys?
A: The following are the mandatory and voluntary
standards for children's toys:
MANDATORY STANDARD
Ban of Lead-Containing Paint and Certain Consumer Products Bearing Lead-Containing
Paint (16 CFR 1303) This mandatory standard (regulation) was issued by a U.S.
government agency and has the force of law. Toys or other articles intended
for use by children are not to be marketed if they bear lead-containing paint
or other surface coatings (ink). Lead-containing paint or other surface coatings
are defined as having lead in excess of 0.06% (600 ppm) of the weight of the
total nonvolatile content of the paint or the weight of the dried paint film.
Paint and similar surface-coating materials such as varnish, shellac and lacquer
are banned from paint intended for use in residences, schools, hospitals,
parks, playgrounds, public buildings, and other areas where consumers will
have direct access to painted surfaces, if the paint or surface coating contains
lead or lead compounds in excess of 0.06% (600 ppm).
VOLUNTARY STANDARDS
Voluntary standards are issued by private groups, often through a consensus
process. Their use is wholly voluntary, unless a state or local governmental
entity has adopted or incorporated them. These standards are often required
by the end receiver of printed products. Although they are not law, they may
be required by customers.
VOLUNTARY SAFETY STANDARD FOR TOYS
(ASTM F 963 - 96a)
This voluntary standard sets limits for the amount of antimony, arsenic, barium,
cadmium, chromium, lead, mercury and selenium in surface-coating materials
applied to children's toys. These limits are as follows:
Antimony
Arsenic
Barium
Cadmium
Chromium
Lead
Mercury
Selenium

EUROPEAN SAFETY STANDARD FOR TOYS
(EN 71-3: 1994)
The European standard for toys sets limits for the same chemicals as the Voluntary
ASTM F-963 standard. All limits are identical except for Barium whose limit
is set at 500 ppm or 0.0500%.

Q: What is a Volatile Organic Compound (VOC)?
A: Volatile Organic Compounds (VOCs) are
defined by the Federal Environmental Protection Agency (EPA) as organic compounds
which participate in atmospheric photochemical reactions. In terms that we
can all understand, a VOC is anything that evaporates and causes air pollution.
Not a VOC:
- Water: Evaporates but doesn't cause harmful air pollution.
- Resin: Doesn't have the ability to evaporate.
- Pigment: Dry powder, therefore doesn't evaporate.
Solvents used in inks and associated products are the main concern to the
coating industry. Solvents have the ability to evaporate and meet the criteria
of an air pollutant. (Examples of VOCs are xylene and toluene.)
Q: Mathematically, what is a VOC?
A: The amount of VOCs in products are determined
by calculating the amount of solvent present in a gallon or liter of ink,
excluding water and EPA-exempt solvents, and expressed in either pounds per
gallon, or grams per liter.
Knowing the weight per gallon (WPG) and the weight solids of a solvent-based
ink, the VOCs can be calculated according to the following equation:
VOC = WPG x (100% minus % solids in product)
For example, a solvent based ink weighing 10.0 pounds per gallon and having
a weight solids of 70% would have the following VOC amount:
VOC = 10.0 WPG x (100% - 70%)
VOC = 10.0 WPG x (30%)
VOC = 3.0 WPG
(3.0 pounds of VOCs exist in each gallon of ink)
To convert pounds per gallon to grams per liter (g/L) use the following conversion
factor:
Lb/Gal to g/L....multiply by 119.84
g/L to Lb/Gal....divide by 119.84
In the example above, to convert 3.0 Lb/Gal of VOCs to g/L, perform the following:
3.0 X 119.84 = 359.5 g/L
(359.5 grams of VOCs exist in each liter of ink)

Q: What is the Hazardous Materials Identification
System (HMIS)?
A: HMIS was developed by the National Paint
and Coatings Association (NPCA) to provide information on the acute health
hazards, flammability and reactivity of products encountered in the workplace
at room temperatures. HMIS is a visual system using colors, numbers, letters
of the alphabet and symbols to communicate risk information to workers. The
HMIS program communicates necessary hazard information to supervisors and
employees in a uniform and easily understandable manner. The program is based
on a rating scheme designed to be as compatible as possible with hazard communication
systems such as ANSI, NIOSH and others used by industry. HMIS codes assigned
are only suggested ratings based on anticipated normal screen printing applications.
The employer has the ultimate responsibility for assigning these ratings and
should fully evaluate the MSDS, work practices and environmental conditions
prior to assigning the appropriate ratings.

Q: What is Waste?
A: Any solid, liquid, or contained gaseous
material that is no longer useable and is either recycled, thrown away or
stored until enough has been generated to treat or dispose.
A non-hazardous waste mixed with either a characteristic or listed waste will
be considered hazardous waste.
Q: How can waste be identified as Hazardous?
A: There are two ways a waste may
be identified as HAZARDOUS:
CHARACTERISTICS OF WASTES: A waste that exhibits any of the following characteristics:
- IGNITABLE - Inks, Solvents - Flash Point less than
140°F
- CORROSIVE - Acids, Caustics - pH less than or equal
to 2 or greater than or equal to 12.5
- REACTIVE - Explosives, Peroxides
- TOXIC - Metals, Pesticides, Organics
LISTED WASTES: A waste is considered hazardous if it appears on any one of
the four lists of hazardous waste contained in EPA regulations. These wastes
have been listed because they either exhibit one of the characteristics described
above or contain any number of toxic constituents that have been shown to
be harmful to health and the environment. The regulations list over 400 hazardous
wastes, including waste derived from manufacturing processes and discarded
commercial chemical products.
Generator Categories
Important: These categories may vary by
state. The categories below dictate the amount of regulations that will be
applicable to the generator. A smaller amount of waste generated means a smaller
amount of applicable regulations.
CONDITIONALLY EXEMPT SMALL QUANTITY GENERATORS: Generates less than 220 lbs/month
of a hazardous waste
SMALL QUANTITY GENERATORS: Generates between 220 - 2200 lbs/month of a hazardous
waste
LARGE QUANTITY GENERATORS: Generates 2200 lbs/month or more of a hazardous
waste
A printer will commonly generate wastes that can be identified as hazardous.
Processes that can generate wastes are screen cleaning, screen reclaiming,
color matching and outdated/unusable materials.
EXAMPLE 1:
If waste ink is accumulated that has a flash point less than 140°F or contains
enough lead to be regulated, then this waste will be considered hazardous.
EXAMPLE 2:
If a screen wash is accumulated that has a flash point greater than 140°F,
but contains a material that is considered toxic (e.g. Methyl Ethyl Ketone)
or contains a listed waste (e.g. Xylene, Toluene), then this waste is considered
hazardous.
