Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

First-aid measures
Eye contact
Immediately flush eyes with plenty of clean water for an extended time, not less than fifteen (15) minutes. Flush longer if there is any indication of residual chemical in the eye. Ensure adequate flushing of the eyes by separating the eyelids with fingers and roll eyes in a circular motion.
Skin contact
Immediately remove contaminated clothing and shoes. Wash the affected area with plenty of soap and water until no evidence of the chemical remains (at least 15-20 minutes). Launder clothing before reuse. Get medical attention if symptoms occur.
Inhalation
If affected, remove to fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration. If any processing vapors, decomposition products, or particulates are inhaled, remove the individual(s) to fresh air. Provide protection before allowing reentry.
Ingestion
Do not induce vomiting. Never give anything by mouth to an unconscious person. Rinse out the mouth with water. Get medical attention immediately.
Fire-fighting measures
Fire and explosive properties
As with all organic dusts, fine particles suspended in air in critical proportions and in the presence of an ignition source may ignite and/or explode. Dust may be sensitive to ignition by electrostatic discharge, electrical arcs, sparks, welding torches, cigarettes, open flame, or other significant heat sources. As a precaution, implement standard safety measures for handling finely divided organic powders. See Section 7 for suggested measures.
N-OXYDIETHYLENETHIOCARBAMYL-N'-OXYDIETHYLENESULFENAMIDE: The following characteristics apply to powder and are expected to apply to dust from pellets reduced to a powder:
-Minimum explosive concentration: 0.03 oz/ft3 (30 g/m3)
-Minimum ignition energy (dust cloud): 0.20 joules
-Maximum rate of pressure rise: 14,700 psi/sec @ 0.1 oz/ft3 (1,010 bars/sec @ 100 g/m3)
-Maximum pressure of explosion: 83 psig @ 0.5 oz/ft3 (5.7 bars-gauge @ 500 g/m3)
-Explosion severity ratio: 5.83 (severe)
-Deflagration Index, Kst (estimate): 355 bar m/sec
-Ignition sensitivity: Strong
-Volume resistivity: 1.01 x 10^14 ohm-cm
-National Electrical Code (NFPA 70): Group G dust.
Extinguishing media
Use water spray, dry chemical, or foam. Carbon dioxide may be ineffective on larger fires due to a lack of cooling capacity which may result in reignition. Avoid hose streams or any method which will create dust clouds.
Fire fighting instructions
Avoid hose streams or any method which will create dust clouds. Wear self-contained breathing apparatus (SCBA) equipped with a full facepiece and operated in a pressure-demand mode (or other positive pressure mode) and approved protective clothing. Personnel without suitable respiratory protection must leave the area to prevent significant exposure to hazardous gases from combustion, burning or decomposition. In an enclosed or poorly ventilated area, wear SCBA during cleanup immediately after a fire as well as during the attack phase of firefighting operations.
Unusual fire/explosion hazards
Irritating or toxic substances may be emitted upon burning, combustion or decomposition. Concentrated dust/air combinations may produce explosive conditions.
Accidental release measures
Containment techniques
Contain by diking with sand, earth or other non-combustible material. If spilled in an enclosed area, ventilate. Do not flush product into public sewer, water systems or surface waters.
Clean-up techniques
Wear proper personal protective clothing and equipment. Using care to avoid dust generation, vacuum or sweep into a closed container for reuse or disposal. Use approved industrial vacuum cleaner for removal. Eliminate ignition sources. Do not sweep or flush spilled product into public sewer, streams or other water systems. Avoid causing dust. If inhalation of dust cannot be avoided, wear an approved particulate respirator. Place into labeled, closed container; store in safe location to await disposal. Change contaminated clothing and launder before reuse. Personal Protective Equipment must be worn.

Handling and storage
Handling
As with any chemical product, use good laboratory/workplace procedures. Do not breathe dust, vapor, mist or gas. Do not ingest, taste, or swallow. Wash thoroughly after handling this product. Always wash up before eating, smoking or using the facilities. Use under well-ventilated conditions. Avoid eye and skin contact. Avoid routine inhalation of dust of any kind. Exercise care when emptying containers, sweeping, mixing or doing other tasks which can create dust. Wash contaminated clothing before reuse. Provide eyewash fountains and safety showers in the work area.
As a precaution to control dust explosion potential, implement the following safety measures: Eliminate ignition sources (e.g., sparks, static buildup, excessive heat, etc.). In general, dust of organic materials is a static charge generator which may be ignited by electrostatic discharge, electrical arcs, sparks, welding torches, cigarettes, open flame, or other significant heat sources. Use spark-proof tools and equipment. Bond, ground and properly vent conveyors, dust control devices and other transfer equipment. Prohibit flow of polymer, powder or dust through non-conductive ducts, vacuum hoses or pipes, etc.; only use grounded, electrically conductive transfer lines when pneumatically conveying product. Good housekeeping and controlling of dusts are necessary for safe handling of product. Prevent accumulation of dust (e.g., well-ventilated conditions, promptly vacuuming spills, cleaning overhead horizontal surfaces, etc.). A properly engineered explosion suppression system must be considered. See standards such as the National Fire Protection Association NFPA 654, "Standard for the Prevention of Dust Explosions in the Plastics Industry"; NFPA 69, "Explosion Prevention Systems"; NFPA 68, "Explosion Venting Protection"; NFPA 77, "Static Electricity" and other standards as the need exists.
Storage
Store cool and dry, under well-ventilated conditions. Avoid extremes of temperature and humidity. Keep container closed when not in use. Do not store in open, unlabeled or mislabeled containers.
