Page 2 of 10

Inhalation: At room temperature, vapors are minimal due to low volatility. Certain operations may 

generate vapor or mist concentrations sufficient to cause respiratory irritation. Such operations include 

those in which the material is heated or sprayed as an aerosol (venting of vessels/lines). 

Ingestion: Low toxicity if swallowed. Small amounts swallowed incidentally as a result of normal 

handling operations are not likely to cause injury; however, swallowing larger amounts may cause 

injury. 

Aspiration hazard: Based on physical properties, not likely to be an aspiration hazard. 

Effects of Repeated Exposure: In rats, repeated dietary ingestion of diethyltoluenediamine (DETDA) 

has caused pancreatic, eye, liver and thyroid effects. 

Cancer Information: Diethyltoluenediamine (DETDA) has caused cancer in long-term animal studies. 

Increased numbers of tumors in the liver, thyroid and possibly the mammary glands were observed in 

rats given DETDA in their diet at exaggerated doses for 2 years.

4. First-aid measures 

Eye Contact: Immediately flush eyes with water; remove contact lenses, if present, after the first 5 

minutes, then continue flushing eyes for at least 15 minutes. Obtain medical attention without delay, 

preferably from an ophthalmologist. Suitable emergency eye wash facility should be immediately 

available. 

Skin Contact: Remove material from skin immediately by washing with soap and plenty of water. 

Remove contaminated clothing and shoes while washing. Seek medical attention if irritation persists. 

Wash clothing before reuse. Discard items which cannot be decontaminated, including leather articles 

such as shoes, belts and watchbands. 

Inhalation: Move person to fresh air; if effects occur, consult a physician. 

Ingestion: If swallowed, seek medical attention. Do not induce vomiting unless directed to do so by 

medical personnel. 

Notes to Physician: No specific antidote. Treatment of exposure should be directed at the control of 

symptoms and the clinical condition of the patient. 

Emergency Personnel Protection: First Aid responders should pay attention to self-protection and 

use the recommended protective clothing (chemical resistant gloves, splash protection). If potential for 

exposure exists refer to Section 8 for specific personal protective equipment. 

5. Fire Fighting Measures 

Extinguishing Media: Water fog or fine spray. Dry chemical fire extinguishers. Carbon dioxide fire 

extinguishers. Foam. Do not use direct water stream. May spread fire. Alcohol resistant foams (ATC 

type) are preferred. General purpose synthetic foams (including AFFF) or protein foams may function, 

but will be less effective. 

Fire Fighting Procedures: Keep people away. Isolate fire and deny unnecessary entry. Use water 

spray to cool fire exposed containers and fire affected zone until fire is out and danger of reignition has 

passed. Fight fire from protected location or safe distance. Consider the use of unmanned hose 

holders or monitor nozzles. Immediately withdraw all personnel from the area in case of rising sound 

from venting safety device or discoloration of the container. Do not use direct water stream. May 

spread fire. Move container from fire area if this is possible without hazard. Burning liquids may be

moved by flushing with water to protect personnel and minimize property damage. Contain fire water 

run-off if possible. Fire water run-off, if not contained, may cause environmental damage. Review the 

"Accidental Release Measures" and the "Ecological Information" sections of this (M)SDS. 

Special Protective Equipment for Firefighters: Wear positive-pressure self-contained breathing 

apparatus (SCBA) and protective fire fighting clothing (includes fire fighting helmet, coat, trousers, 

boots, and gloves). Avoid contact with this material during fire fighting operations. If contact is likely, 

change to full chemical resistant fire fighting clothing with self-contained breathing apparatus. If this is 

not available, wear full chemical resistant clothing with self-contained breathing apparatus and fight fire 

from a remote location. For protective equipment in post-fire or non-fire clean-up situations, refer to 

the relevant sections. 

Unusual Fire and Explosion Hazards: Container may rupture from gas generation in a fire situation. 

Violent steam generation or eruption may occur upon application of direct water stream to hot liquids. 

Hazardous Combustion Products: During a fire, smoke may contain the original material in addition 

to combustion products of varying composition which may be toxic and/or irritating. Combustion 

products may include and are not limited to: Nitrogen oxides. Carbon monoxide. Carbon dioxide. 

6. Accidental Release Measures 

Steps to be Taken if Material is Released or Spilled: Contain spilled material if possible. Absorb 

with materials such as: Dirt. Sand. Sawdust. Collect in suitable and properly labeled containers. 

Wash the spill site with water. See Section 13, Disposal Considerations, for additional information. 

Personal Precautions: Isolate area. Keep unnecessary and unprotected personnel from entering the 

area. Spilled material may cause a slipping hazard. Refer to Section 7, Handling, for additional 

precautionary measures. Use appropriate safety equipment. For additional information, refer to 

Section 8, Exposure Controls and Personal Protection. 

Environmental Precautions: Prevent from entering into soil, ditches, sewers, waterways and/or 

groundwater. See Section 12, Ecological Information. Spills or discharge to natural waterways is likely 

to kill aquatic organisms.

A "skin" notation following the inhalation exposure guideline refers to the potential for dermal 

absorption of the material including mucous membranes and the eyes either by contact with vapors or 

by direct skin contact. 

It is intended to alert the reader that inhalation may not be the only route of exposure and that 

measures to minimize dermal exposures should be considered. 

Personal Protection

Eye/Face Protection: Use chemical goggles. 

Skin Protection: Use protective clothing chemically resistant to this material. Selection of specific 

items such as face shield, boots, apron, or full body suit will depend on the task. 

Hand protection: Use gloves chemically resistant to this material. Examples of preferred 

glove barrier materials include: Butyl rubber. Natural rubber ("latex"). Neoprene. 

Nitrile/butadiene rubber ("nitrile" or "NBR"). Polyethylene. Ethyl vinyl alcohol laminate 

("EVAL"). Polyvinyl alcohol ("PVA"). Polyvinyl chloride ("PVC" or "vinyl"). NOTICE: The 

selection of a specific glove for a particular application and duration of use in a workplace 

should also take into account all relevant workplace factors such as, but not limited to: Other 

chemicals which may be handled, physical requirements (cut/puncture protection, dexterity, 

thermal protection), potential body reactions to glove materials, as well as the 

instructions/specifications provided by the glove supplier. 

Respiratory Protection: Respiratory protection should be worn when there is a potential to exceed 

the exposure limit requirements or guidelines. If there are no applicable exposure limit requirements 

or guidelines, wear respiratory protection when adverse effects, such as respiratory irritation or 

discomfort have been experienced, or where indicated by your risk assessment process. For most 

conditions, no respiratory protection should be needed; however, if material is heated or sprayed, use 

an approved air-purifying respirator. The following should be effective types of air-purifying 

respirators: Organic vapor cartridge with a particulate pre-filter. 

Ingestion: Use good personal hygiene. Do not consume or store food in the work area. Wash hands 

before smoking or eating. 

Engineering Controls

Ventilation: Use local exhaust ventilation, or other engineering controls to maintain airborne levels 

below exposure limit requirements or guidelines. If there are no applicable exposure limit 

requirements or guidelines, general ventilation should be sufficient for most operations. Local exhaust 

ventilation may be necessary for some operations.
