incompatible materials. (See Incompatibility section). Do not store or consume food, drink, or
tobacco where they may become contaminated with this material. All labeled precautions must be
observed when handling, storing and transporting empty containers due to product residues. Triple
rinse before disposal.
Ventilation: Match ventilation to conditions of use so as not to exceed any applicable exposure limits
(see Section 8). Good general conditions of 10 or more room volumes per hour in the work area
recommended.

Respiratory Protection: When this product is used in the intended way, no respiratory protection is
anticipated to be necessary. If use conditions do not maintain vapors or fumes below exposure
limits use suitable respiratory equipment. Respirator type: full-face organic vapor/N95. If hazardous
decomposition products are likely to have been released. Respirator type: Acid gas. See Stability
and Reactivity Section.
Ventilation: Avoid exposure to mists and vapors by mixing solutions in closed vessels and/or under
local exhaust ventilation. Good general ventilation (typically 10 air changes per hour) should be
used. Ventilation rates should match conditions of use.
Eye Protection: Wear safety glassed with side shields or protective goggles whenever mixing or
handling solutions.
Skin and body protection: Wear impervious gloves and protective clothing suitable for the risk of
exposure.

11. Toxicological information
Effects of exposure for hydroquinone
General advice: This mixture contains hydroquinone which is classified as a dermal sensitizer in
some jurisdictions. This mixture is not expected to be a dermal sensitization hazard to humans. The
toxicological properties of this solution have not been investigated.
Contains: Hydroquinone. Hydroquinone has been classified as a Category 3 mutagen and carcinogen
by the European Union based upon testing rats and mice given hydroquinone by stomach tube or at
high dietary levels. The International Agency for Research on Cancer (IARC) under ranking for cancer
potential has classified hydroquinone in Group 3, i.e. "not classifiable as a carcinogen. In the EU a
Category 3 mutagen is given a risk phrase R68" Possible risk of irreversible effects" at concentrations
above 1%, and a Category 3 carcinogen attracts a risk phrase R40 "Limited evidence of carcinogenic
effect at concentrations above 1%. Exposure to products containing such substances should be
controlled to below established control limits and special care should be taken with pregnant or breast-
feeding women to ensure appropriate controls are in place to control the risk.
Acute Toxicity for hydroquinone:
LD50 Oral- rat- 302 mg/kg
LD50 Dermal ?Mammal ?5,970 mg/kg
Inhalation: Expected to be a low hazard for recommended handling.
Eyes: No specific hazard known. May cause transient irritation.
Skin: May cause sensitization by skin contact.
Ingestion: Expected to be a low ingestion hazard. However, some asthmatics or sulfite-sensitive
individuals may experience wheezing, chest tightness, stomach upset, hives, faintness, weakness and
diarrhea.

13. Disposal considerations
Working solution: Waste material is currently classified as hazardous under Council Directive
91/689/EEC. The European Waste Catalogue Code is 09 01 01 Water based developer and activator.
The preferred options for disposal are to send to licensed reclaimers, or to permitted incinerators. Any
disposal practice must be in compliance with federal, state, and local regulations. Do not dump into
sewers, ground, or any body of water.
Product containers: Triple rinse with water. Waste product packaging may be consigned for
recovery or disposal as non hazardous waste. Whenever possible, minimize waste by using the rinse
water to make up the working solution. The European Waste Catalogue Code is 15 01 02 plastic
packaging.
Waste product packaging contaminated by residues of hazardous contents should be consigned for
disposal as hazardous waste. In this instance, the European Waste Catalogue Code is 15 01 10
packaging containing residues of or contaminated by dangerous substances.
