Hazards and Protection.
Keep away from heat, sparks, and flame. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Do not expose to air. Store protected from light. Store under an inert atmosphere.
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use only in a well ventilated area. Minimize dust generation and accumulation. Do not breathe dust, vapor, mist, or gas. Do not get in eyes, on skin, or on clothing. Do not ingest or inhale. Store protected from light. Handle under an inert atmosphere. Store protected from air.
Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective clothing to prevent skin exposure. Clothing: Wear appropriate protective gloves to prevent skin exposure.
A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use.
Vacuum or sweep up material and place into a suitable disposal container. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, using the appropriate protective equipment. Avoid generating dusty conditions. Provide ventilation. Place under an inert atmosphere.
Stable at normal temperatures in tightly closed containers under an inert atmosphere. Substance undergoes color change upon exposure to light and air. Volatile in steam. May undergo auto-oxidation at 25 C.
Strong oxidizing agents, bases, acid chlorides, iron, nitric acid, acid anhydrides, albumin, alkalies, iron salts, antipyrine, acetanilide, air, menthol, urethane, spirit nitrous ether, camphor.
Carbon monoxide, irritating and toxic fumes and gases, carbon dioxide.

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Water runoff can cause environmental damage. Dike and collect water used to fight fire. Dusts at sufficient concentrations can form explosive mixtures with air. Extinguishing media: Water spray may cause frothing. Cool containers with flooding quantities of water until well after fire is out. In case of fire, use carbon dioxide, dry chemical powder or appropriate foam.
Containers may explode.
Fire may produce irritating, corrosive and/or toxic gases.
TLV: 10 ppm; 45 mg/m3 (as TWA); 20 ppm; 90 mg/m3 (STEL) (ACGIH 1997). MAK: 10 ppm; 45 mg/m3 (1997). NIOSH REL: TWA 10 ppm (45 mg/m3) ST 20 ppm (90 mg/m3)
May cause liver and kidney damage. Repeated exposure may cause sensitization dermatitis. Repeated exposure may cause damage to the spleen. Laboratory experiments have resulted in mutagenic effects.
May cause severe gastrointestinal tract irritation with nausea, vomiting and possible burns. May cause methemoglobinemia, cyanosis, convulsions, and death.
Dust is irritating to the respiratory tract. Causes irritation of the mucous membrane and upper respiratory tract.
Causes moderate skin irritation. May be absorbed through the skin in harmful amounts. May cause skin sensitization, an allergic reaction, which becomes evident upon re-exposure to this material. If absorbed, may cause symptoms similar to those for ingestion. Resorcinol has been known to cause hyperemia, itch, dermatitis, edema, and corrosion.
Contact with eyes may cause severe irritation, and possible eye burns. Contact of the eye with resorcinol has caused necrosis and corneal perforation.
Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.
Get medical aid immediately. Remove from exposure to fresh air immediately. If breathing is difficult, give oxygen. DO NOT use mouth-to-mouth respiration. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask.
Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Destroy contaminated shoes.
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
