4.3 Indication of immediate medical attention and special treatment needed, if necessary
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.

Occupational Exposure limit values
Handle with caution in the workplace.
NIOSH considers ethylene dichloride; hexachloroethane; 1,1,2,2-tetrachloroethane; and 1,1,2-trichloroethane; to be potential occupational carcinogens. Additionally, NIOSH recommends that the other five chloroethane compounds: 1,1-dichloroethane; ethyl chloride; methyl chloroform; pentachloroethane; and 1,1,1,2-tetrachloroethane be treated in the workplace with caution because of their structural similarity to the four chloroethanes shown to be carcinogenic in animals.

12.2 Persistence and degradability
Biodegradation data are not available for 1,1,1,2-tetrachloroethane(SRC, 2008); however, biodegradation data for the isomer 1,1,2,2-tetrachloroethane indicate that degradation will be slow under aerobic conditions, but may proceed under anaerobic conditions(1).
12.3 Bioaccumulative potential
An estimated BCF of 12 was calculated in fish for 1,1,1,2-tetrachloroethane(SRC), using a water solubility of 1.07X10+3 mg/L at 25°C(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
The experimentally determined Koc for 1,1,1,2-tetrachloroethane is 399(1). According to a classification scheme(2), this Koc value suggests that 1,1,1,2-tetrachloroethane is expected to have moderate mobility in soil.
