4.3 Indication of immediate medical attention and special treatment needed, if necessary
/SRP:/ Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on the left side (head-down position, if possible) to maintain an open airway and prevent aspiration.

10.3 Possibility of hazardous reactions
This material is combustible when exposed to heat or flame.Phenols, such as CREOSOTE, do not behave as organic alcohols, as one might guess from the presence of a hydroxyl (-OH) group in their structure. Instead, they react as weak organic acids. Phenols and cresols are much weaker as acids than common carboxylic acids (phenol has pKa = 9.88). These materials are incompatible with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides. Flammable gas (H2) is often generated, and the heat of the reaction may ignite the gas. Heat is also generated by the acid-base reaction between phenols and bases. Such heating may initiate polymerization of the organic compound. Phenols are sulfonated very readily (for example, by concentrated sulfuric acid at room temperature). The reactions generate heat. Phenols are also nitrated very rapidly, even by dilute nitric acid. This compound is incompatible with acacia, albumin, oxidizers and cupric, ferric, gold and silver salts.

- Toxicity to fish: no data available
- Toxicity to daphnia and other aquatic invertebrates: EC50; Species: Daphnia magna (Water flea, age 12 hr); Conditions: freshwater, static, 18°C; Concentration: 25900 ug/L for 48 hr; Effect: intoxication, immobilization /formulation

12.2 Persistence and degradability
AEROBIC: o-Methoxyphenol, present at 100 mg/L, reached 97% of its theoretical BOD in four weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1).
12.3 Bioaccumulative potential
An estimated BCF of 3 was calculated in fish for o-methoxyphenol(SRC), using log Kow of 1.32(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soil
A log Koc of 1.60 for o-methoxyphenol, corresponding to a Koc of 40(SRC), was experimentally determined in a Brookston clay loam soil(1). A log Koc of 1.56(2), corresponding to a Koc of 36(SRC) has also been reported. According to a classification scheme(3), these Koc values suggest that o-methoxyphenol is expected to have very high mobility in soil. The pKa of o-methoxyphenol is 9.98(4), indicating that this compound will exist primarily in the undissociated form in the environment(SRC). The adsorption of the phenol occurrs by hydrogen bonding to sites on soil surfaces; ortho-substitution generally results in decreased adsorption compared to para-substitution due to steric hindrance(1).
12.5 Other adverse effects
no data available
13.Disposal considerations
13.1 Disposal methods
Product
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Contaminated packaging
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
