Tremors, convulsions, shortness of breath, inhibition of respiratory system. (USCG, 1999)

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 as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Phenols and related compounds

Activated carbon is a good method for removing chlorophenols from water. Competitive adsorption occurs between chlorophenols & humic substances present in nearly all municipal water supplies. This competition decr the capacity of carbon for chlorophenols. Chlorophenols

NO open flames. Prevent build-up of electrostatic charges (e.g., by grounding). Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.

Fireproof. Store in an area without drain or sewer access. Provision to contain effluent from fire extinguishing. Separated from strong oxidants and food and feedstuffs. Ventilation along the floor.SRP: Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants.

Evaluation: There is limited evidence in humans for the carcinogenicity of combined exposures to polychlorophenols or to their sodium salts. There is evidence suggesting lack of carcinogenicity of 2,4-dichlorophenol in experimental animals. ... Overall evaluation: Combined exposures to polychlorophenols or to their sodium salts are possibly carcinogenic to humans (Group 2B). Polychlorophenols and their sodium salts

The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. The hot liquid may cause severe skin burns. Exposure to the molten substance may result in extensive skin absorption and rapid death. Inhalation of the vapour may cause lung oedema. See Notes. Medical observation is indicated. The substance may cause effects on the central nervous system.

A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C; when in molten form, however, evaporation will be much faster.

AEROBIC: Using a static-culture flask-screening procedure with a settled wastewater inoculum, 2,4-dichlorophenol was found to be degradable with rapid microbial adaptation as 99-100% of initial concentration were degraded within 7 days(1). Using a Warburg respirometer and phenol-adapted bacteria (bacteria isolated from garden soil, river mud, compost and waste lagoon sediment), 95% of initial 2,4-dichlorophenol (200 ppm) was degraded within 7-10 days(2). Based on COD determination, 98% of initial 2,4-dichlorophenol was degraded in a BOD system with an activated sludge inoculum during a 20-day inoculation period(3). When activated sludge was exposed to 2,4-dichlorophenol at levels of 100 mg/L of sludge, 75% of the chemical disappeared in two days, and essentially 100% was gone in five days(4). However, 2,4-dichlorophenol, present at 100 mg/L, reached 0% of its theoretical BOD in 4 weeks using an activated sludge inoculum in the Japanese MITI test(5).

A BCF range of 7.1 to 69 was calculated in fish for 2,4-dichlorophenol(SRC), using carp (Cyprinus carpio) which were exposed to 30 ppb test compound over an 8-week period(1). The BCF of 2,4-dichlorophenol in goldfish ranged from 34 to 100(3,4); the BCF in an unspecified fish specie was 100(3) and in trout was 10(4). According to a classification scheme(2), these BCF values suggest the potential for bioconcentration in aquatic organisms is low to moderate(SRC). The BCF of 2,4-dichlorophenol in algae ranged from 257 to 263(3,4).

The Koc of 2,4-dichlorophenol ranged from approximately 200 to 5,000 in soil adsorption studies using five mineral soils(1); the most important factors controlling the degree of adsorption were pH and percentage of iron oxide in the soil(1). In batch soil adsorption experiments conducted at pH 10, 2,4-dichlorophenol exhibited a soil equilibrium partition coefficient (Kp) of 0.0+/-0.5 indicating that adsorption was not occurring(2); 2,4-dichlorophenol has a pKa of 7.8 at 20 deg C which indicates that it will exist predominantly in the ionized form at pH 10(2); ionized phenols will generally not sorb to neutral or negatively charged soil organic matter as well as the non-dissociated form(2). The adsorption of the dichlorophenol isomers (including 2,4-dichlorophenol) onto Wyoming bentonite clay was found to be pH dependent with maximum adsorption occurring when ionization of the isomers was less than 50% based on pKa values(3). A 2,4-dichlorophenol Koc of 126 was measured in a clay loam soil from Michigan State University(4).

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.

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.

The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential.Isolate contaminated clothing by sealing in a bag or other container.
