3-2. Physiological Action and First Aid.

WARNING

Contact with DS2 can cause irritation to personnel with chronic pulmonary, asthmatic,

renal, skin, or central nervous system conditions. Pregnant females should not be

exposed to DS2 under any circumstances.

DS2 is a caustic material that is extremely irritating to the skin, eyes, and respiratory tract and with direct contact will

damage these tissues. The visible effects depend on the area and duration of exposure, and on the amount of substance

present. Health effects can range from mild burns and primary irritation to the cornea to severe burns to the throat and

windpipe. Exposure to high vapor concentrations of DS2 can cause nausea, vomiting, and respiratory irritation as serious

effects. Exposure to the EGME in DS2 may cause central nervous system depression and liver damage. Although not

definitely established in humans, EGME could potentially cause adverse reproductive effects in male and female workers

(including teratogenesis) and this is a major concern with EGME. Thus appropriate controls should be established to

minimize worker exposure to EGME. Repeated skin and respiratory exposures to DETA can result in skin sensitization

and asthma.

Based on these effects, a potential toxic hazard exists with DS2 (and its components) and protective measures to prevent

inhalation of vapors and skin contact must be followed. Avoid inhaling vapors. Avoid contact with skin, eyes, or clothing.

If DS2 is inhaled, remove to fresh air. If breathing has stopped, apply artificial respiration. If breathing is difficult, give

oxygen. Additional supportive measures may be required. If eyes are exposed, Immediately flush the eyes with large

amounts of water for at least 15 minutes. In case of skin contact, blot off DS2 and then rinse skin with water until

soapiness is no longer present. If DS2 is ingested and the patient is conscious, give as much milk or water as possible.

Do not induce vomiting. Seek immediate medical attention in each of the above cases. Supportive measures may be

required.

3-3. Protection. Personnel performing any operations where contact with DS2 is a certainty must wear personal

protection equipment (PPE). The type and level of PPE to be worn depends on where the operation is being performed

and the anticipated severity of the hazard. These operations are:(1) General Inspection - Regular surveillance inspections

performed in accordance with Sections 4-2 and 4-5 below where the probability of
