5.Fire-fighting measures 5.1 Extinguishing media Suitable extinguishing mediaExcerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]: SMALL FIRE: Dry chemical, CO2 or water spray. LARGE FIRE: Dry chemical, CO2, alcohol-resistant foam or water spray. Move containers from fire area if you can do it without risk. Dike fire-control water for later disposal; do not scatter the material. FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Do not get water inside containers. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. (ERG, 2016)
5.2 Specific hazards arising from the chemicalWhen heated to decomposition it emits very toxic fumes of chlorides, nitrogen oxides, and sulfur oxides. (EPA, 1998)

6.3 Methods and materials for containment and cleaning upPick up and arrange disposal. Sweep up and shovel. Keep in suitable, closed containers for disposal.
7.Handling and storage 7.1 Precautions for safe handlingAvoid contact with skin and eyes. Avoid formation of dust and aerosols. Avoid exposure - obtain special instructions before use.Provide appropriate exhaust ventilation at places where dust is formed. For precautions see section 2.2.
7.2 Conditions for safe storage, including any incompatibilitiesStore in cool place. Keep container tightly closed in a dry and well-ventilated place.
8.Exposure controls/personal protection 8.1 Control parameters Occupational Exposure limit valuesno data available
Biological limit valuesno data available
8.2 Appropriate engineering controlsHandle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday.
8.3 Individual protection measures, such as personal protective equipment (PPE) Eye/face protectionSafety glasses with side-shields conforming to EN166. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).
Skin protectionWear impervious clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique(without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.
Respiratory protectionWear dust mask when handling large quantities.

10.2 Chemical stabilityStable under recommended storage conditions.
10.3 Possibility of hazardous reactionsWhen heated to decomposition it emits very toxic fumes of chlorides, nitrogen oxides, and sulfur oxides. [EPA, 1998]. Organosulfides are incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. Many of these compounds may liberate hydrogen sulfide upon decomposition or reaction with an acid.

12.3 Bioaccumulative potentialBased on an estimated log Kow of 1.20(1), the BCF for 2-chlorophenylthiourea can be estimated to be 4.8 from a recommended regression-derived equation(2,SRC). This indicates that environmental bioconcentration is not significant(SRC).
12.4 Mobility in soilBased on an estimated log Kow of 1.20(1), the Koc for 2-chlorophenylthiourea can be estimated to range from 11-107 using various regression-derived equations(2,SRC); these Koc estimations indicate high to very high soil mobility(3). Although high soil mobility can be predicted from the log Kow value, 2-chlorophenylthiourea may undergo significant adsorption in soil due to a covalent bonding with humic materials(SRC). Secondary amines (such as N-methylaniline) have been observed to undergo covalent bonding with humates(4) an initial rapid (and reversible) bonding phase is followed by a slow reaction (that is not readily reversible) in which the amine compound is chemically altered to yield an amino-substituted quinone(4). This covalent bonding process represents a mechanism in which aromatic amines may be converted to latent form in the biosphere(4).
12.5 Other adverse effectsno data available
13.Disposal considerations 13.1 Disposal methods ProductThe 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 packagingContainers 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.
